Greenbentin-SG/854/AG

Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) is a non-ionic surfactant ideal for use in rinse aids. This alkoxylated alcohol is low foaming, biodegradable, offers excellent rinsing, and very good wetting.

Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) is a chemical reaction in which ethylene oxide adds to a substrate. Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) is the most widely practiced alkoxylation, which involves the addition of epoxides to substrates.

In the usual application, alcohols and phenols are converted into R(OC2H4)nOH where n ranges from 1 to 10. Such compounds are called Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG). Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) are often converted to related species called ethoxysulfates. Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) and ethoxysulfates are surfactants, used widely in cosmetic and other commercial products.[1] The process is of great industrial significance with more than 2,000,000 metric tons of various ethoxylates produced worldwide in 1994.

Production of Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG)

The process was developed at the Ludwigshafen laboratories of IG Farben by Conrad Schöller and Max Wittwer during the 1930s.

Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG)

Industrial Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) is primarily performed upon fatty alcohols in order to generate fatty Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (FAE’s), which are a common form of nonionic surfactant (e.g. octaethylene glycol monododecyl ether). Such alcohols may be obtained by the hydrogenation of fatty acids from seed oils,[5] or by hydroformylation in the Shell higher olefin process.[6] The reaction proceeds by blowing ethylene oxide through the alcohol at 180 °C and under 1-2 bar of pressure, with potassium hydroxide (KOH) serving as a catalyst.[7] The process is highly exothermic (ΔH -92 kJ/mol of ethylene oxide reacted) and requires careful control to avoid a potentially disastrous thermal runaway.

ROH + n C2H4O → R(OC2H4)nOH

The starting materials are usually primary alcohols as they react ~10-30x faster than do secondary alcohols.[8] Typically 5-10 units of ethylene oxide are added to each alcohol,[6] however Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alkoxylated alcohol) can be more prone to Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) than the starting alcohol, making the reaction difficult to control and leading to the formation of a product with varying repeat unit length (the value of n in the equation above). Better control can be afforded by the use of more sophisticated catalysts,[9] which can be used to generate narrow-range ethoxylates. Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alkoxylated alcohol) are considered to be a high production volume (HPV) chemical by the US EPA.[10]

Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG)/propoxylation

Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) is sometimes combined with propoxylation, the analogous reaction using propylene oxide as the monomer. Both reactions are normally performed in the same reactor and may be run simultaneously to give a random polymer, or in alternation to obtain block copolymers such as poloxamers.[7] Propylene oxide is more hydrophobic than ethylene oxide and its inclusion at low levels can significantly affect the properties of the surfactant. In particular Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alkoxylated alcohol) which have been ‘capped’ with ~1 propylene oxide unit are extensively marketed as defoamers.

Ethoxysulfates

Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alkoxylated alcohol) are often converted to the corresponding organosulfates, which can be easily deprotonated to give anionic surfactants such as sodium laureth sulfate. Being salts, ethoxysulfates exhibit good water solubility (high HLB value). The conversion is achieved by treating Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alkoxylated alcohol) with sulfur trioxide.[11] Laboratory scale synthesis may be performed using chlorosulfuric acid:

R(OC2H4)nOH + SO3 → R(OC2H4)nOSO3H

R(OC2H4)nOH + HSO3Cl → R(OC2H4)nOSO3H + HCl

The resulting sulfate esters are neutralized to give the salt:

R(OC2H4)nOSO3H + NaOH → R(OC2H4)nOSO3Na + H2O

Small volumes are neutralized with alkanolamines such as triethanolamine (TEA). In 2006, 382,500 metric tons of alcohol ethoxysulfates (Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alkoxylated alcohol)) were consumed in North America.

Other materials

Although alcohols are by far the major substrate for Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG), many nucleophiles are reactive toward ethylene oxide. Primary amines will react to give di-chain materials such as polyethoxylated tallow amine. The reaction of ammonia produces important bulk chemicals such as ethanolamine, diethanolamine, and triethanolamine.

Applications of ethoxylated products

Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (AE) and alcohol ethoxysulfates (Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alkoxylated alcohol)) are surfactants found in products such as laundry detergents, surface cleaners, cosmetics, agricultural products, textiles, and paint.

Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG)

As Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alkoxylated alcohol) based surfactants are non-ionic they typically require longer ethoxylate chains than their sulfonated analogues in order to be water-soluble.[15] Examples synthesized on an industrial scale include octyl phenol ethoxylate, polysorbate 80 and poloxamers. Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) is commonly practiced, albeit on a much smaller scale, in the biotechnology and pharmaceutical industries to increase water solubility and, in the case of pharmaceuticals, circulatory half-life of non-polar organic compounds. In this application, Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) is known as “PEGylation” (polyethylene oxide is synonymous with polyethylene glycol, abbreviated as PEG). Carbon chain length is 8-18 while the ethoxylated chain is usually 3 to 12 ethylene oxides long in home products.[16][page needed] They feature both lipophilic tails, indicated by the alkyl group abbreviation, R, and relatively polar headgroups, represented by the formula (OC2H4)nOH.

Alcohol ethoxysulfates

Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alkoxylated alcohol) found in consumer products generally are linear alcohols, which could be mixtures of entirely linear alkyl chains or of both linear and mono-branched alkyl chains. A high-volume example of these is sodium laureth sulfate a foaming agent in shampoos and liquid soaps, as well as industrial detergents.

Human health for Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG)

Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) are not observed to be mutagenic, carcinogenic, or skin sensitizers, nor cause reproductive or developmental effects.[18] One byproduct of Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) is 1,4-dioxane, a possible human carcinogen.[19] Undiluted Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alkoxylated alcohol) can cause dermal or eye irritation. In aqueous solution, the level of irritation is dependent on the concentration. Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alkoxylated alcohol) are considered to have low to moderate toxicity for acute oral exposure, low acute dermal toxicity, and have mild irritation potential for skin and eyes at concentrations found in consumer products.

Aquatic and environmental aspects

Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alkoxylated alcohol) are usually released down the drain, where they may be adsorbed into solids and biodegrade through anaerobic processes, with ~28-58% degraded in the sewer.[20][non-primary source needed] The remaining Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alkoxylated alcohol) are treated at waste water treatment plants and biodegraded via aerobic processes with less than 0.8% of Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alkoxylated alcohol) released in effluent.[20] If released into surface waters, sediment or soil, Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alkoxylated alcohol) will degrade through aerobic and anaerobic processes or be taken up by plants and animals.

Toxicity to certain invertebrates has a range of EC50 values for linear AE from 0.1 mg/l to greater than 100 mg/l. For branched alcohol exthoxylates, toxicity ranges from 0.5 mg/l to 50 mg/l.[16] The EC50 toxicity for algae from linear and branched Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alkoxylated alcohol) was 0.05 mg/l to 50 mg/l. Acute toxicity to fish ranges from LC50 values for linear AE of 0.4 mg/l to 100 mg/l, and branched is 0.25 mg/l to 40 mg/l. For invertebrates, algae and fish the essentially linear and branched Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alkoxylated alcohol) are considered to not have greater toxicity than Linear AE.

Biodegradation of Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG)

The degradation of Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alkoxylated alcohol) proceeds by ω- or β-oxidation of the alkyl chain, enzymatic hydrolysis of the sulfate ester, and by cleavage of an ether bond in the Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alkoxylated alcohol) producing alcohol or Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alkoxylated alcohol) and an ethylene glycol sulfate. Studies of aerobic processes also found Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alkoxylated alcohol) to be readily biodegradable.[12] The half-life of both AE and Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alkoxylated alcohol) in surface water is estimated to be less than 12 hours.[21][non-primary source needed] The removal of Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alkoxylated alcohol) due to degradation via anaerobic processes is estimated to be between 75 and 87%.

In water

Flow-through laboratory tests in a terminal pool of Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alkoxylated alcohol) with mollusks found the NOEC of a snail, Goniobasis and the Asian clam, Corbicula to be greater than 730 ug/L. Corbicula growth was measured to be affected at a concentration of 75 ug/L. The mayfly, genus Tricorythodes has a normalized density NOEC value of 190 ug/L.

Human safety of Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG)

Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alkoxylated alcohol) has not been found to be genotoxic, mutagenic, or carcinogenic.

Alcohols, C8-10, ethoxylated, propoxylated, (Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG)) are a small subset of alcohol ethoxylates which have many applications, but are primarily used in detergents and as surfactants because they are particularly effective at removing oily soils. They are also used in commercial and residential cleaners (3) and hydraulic fracturing.

Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcohol ethoxylate)s are a class of compounds that are commonly used throughout many industrial practices and commercial markets. These compounds are synthesized via the reaction of a fatty alcohol and ethylene oxide, resulting in a molecule that consists of two main components, (1) the oleophilic, carbon-rich, fatty alcohol and (2) the hydrophilic, polyoxyethylene chain.

Due the basic structure of these compounds that pair a hydrophobic portion (water-hating) with a hydrophilic component (water-loving), Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcohol ethoxylate)s are a versatile class of compounds, commonly referred to as surfactants. Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcohol ethoxylate) surfactants enhance the mixing and solubilization of oil and water by having these contrasting sections within the same compound. With this unique structure, a single molecule can inhabit the interface of two immiscible phases (i.e. oil and water), effectively bringing them closer together and lowering the interfacial energy associated between them. By lowering this energy, many novel solution applications can be accessed by increasing the homogeneity of these two previously immiscible phases.

What is Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcohol ethoxylate)?

Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcohol ethoxylate)s can vary widely in their properties and applications because the materials used to make these products can vary in their structures and amounts. For instance, fatty alcohols, which are commonly sourced from natural materials, can provide different structures depending on the plant from which they were extracted. Common natural sources of fatty alcohols include the palm oil tree (including both palm oil and palm kernel oil), oils from the coconut tree, and the oil from rapeseed. Each of these natural sources differs in its distribution of carbon chains, making an Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcohol ethoxylate) from coconut oil alcohol different from an Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcohol ethoxylate) made from the alcohol of a palm kernel oil.

Oxiteno offers a wide array of Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcohol ethoxylate)s that have been sourced from natural materials (Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcohol ethoxylate)s), each of which provide a unique set of application properties. Additionally, fatty alcohols can also be synthesized from petroleum products, providing unique structures in the hydrophobic moiety that are not commonly observed in nature. Branched alcohols and alcohols of specific carbon distributions can be attained using synthetic starting materials, all of which strongly affect the Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcohol ethoxylate)’s final properties. If you’re seeking surfactant companies, please visit the Oxiteno website to see our large portfolio of Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcohol ethoxylate)s from synthetic sources.

Alternatively, the length of the polyoxyethylene component (i.e. the hydrophilic portion) of the Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcohol ethoxylate) provides this class of compounds with a wide assortment of water solubilities and detergency properties. Increasing the amount of ethylene oxide on the Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcohol ethoxylate) typically increases its water solubility, as well as increases the hydrophilic/lipophilic balance (HLB) of the compound. Ranging in arbitrary units of 1-20, the HLB of a nonionic surfactant can be calculated and used to determine the propensity of a compound to work effectively in a given solution of oil and water. Lower HLB values (< 10) are commonly used for oil-rich solutions while surfactants with higher HLB values (> 10) are typically most efficient in oil-in-water emulsions.

Greenbentin-SG / 854 / AG

Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) est un surfactant non ionique idéal pour une utilisation dans les produits de rinçage. Cet alcool alcoxylé est peu moussant, biodégradable, offre un excellent rinçage et un très bon mouillage.

Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) est une réaction chimique dans laquelle l’oxyde d’éthylène s’ajoute à un substrat. Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) est l’alcoxylation la plus largement pratiquée, qui implique l’ajout d’époxydes aux substrats.

Dans l’application habituelle, les alcools et les phénols sont convertis en R (OC2H4) nOH où n va de 1 à 10. De tels composés sont appelés Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG). Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) sont souvent convertis en espèces apparentées appelées éthoxysulfates. Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) et les éthoxysulfates sont des tensioactifs largement utilisés dans les cosmétiques et autres produits commerciaux. [1] Le processus est d’une grande importance industrielle avec plus de 2 000 000 de tonnes métriques de divers éthoxylates produits dans le monde en 1994.

Production de Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG)

Le procédé a été développé dans les laboratoires Ludwigshafen d’IG Farben par Conrad Schöller et Max Wittwer dans les années 1930.

Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG)

Industrial Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) est principalement réalisé sur des alcools gras afin de générer du Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) gras (FAE), qui sont une forme courante de tensioactif non ionique (par exemple, l’éther monododécylique d’octaéthylène glycol). Ces alcools peuvent être obtenus par hydrogénation d’acides gras à partir d’huiles de graines, [5] ou par hydroformylation dans le procédé Shell pour oléfines supérieures. [6] La réaction se déroule en soufflant de l’oxyde d’éthylène à travers l’alcool à 180 ° C et sous 1 à 2 bars de pression, l’hydroxyde de potassium (KOH) servant de catalyseur. [7] Le processus est hautement exothermique (ΔH -92 kJ / mol d’oxyde d’éthylène ayant réagi) et nécessite un contrôle minutieux pour éviter un emballement thermique potentiellement désastreux.

ROH + n C2H4O → R (OC2H4) nOH

Les matières premières sont généralement des alcools primaires car ils réagissent environ 10 à 30 fois plus vite que les alcools secondaires. [8] En général, 5 à 10 unités d’oxyde d’éthylène sont ajoutées à chaque alcool [6], mais le Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcool alcoxylé) peut être plus sujet au Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) que l’alcool de départ, ce qui rend la réaction difficile pour contrôler et conduire à la formation d’un produit avec une longueur d’unité de répétition variable (la valeur de n dans l’équation ci-dessus). Un meilleur contrôle peut être assuré par l’utilisation de catalyseurs plus sophistiqués, [9] qui peuvent être utilisés pour générer des éthoxylates à plage étroite. Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcool alcoxylé) est considéré comme un produit chimique à haut volume de production (HPV) par l’US EPA. [10]

Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) / propoxylation

Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) est parfois combiné avec la propoxylation, la réaction analogue utilisant l’oxyde de propylène comme monomère. Les deux réactions sont normalement effectuées dans le même réacteur et peuvent être effectuées simultanément pour donner un polymère statistique, ou en alternance pour obtenir des copolymères séquencés tels que les poloxamères. [7] L’oxyde de propylène est plus hydrophobe que l’oxyde d’éthylène et son inclusion à de faibles niveaux peut affecter de manière significative les propriétés du tensioactif. En particulier, le Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcool alcoxylé) qui a été «coiffé» avec ~ 1 unité d’oxyde de propylène est largement commercialisé comme antimousse.

Éthoxysulfates

Le Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcool alcoxylé) est souvent converti en organosulfates correspondants, qui peuvent être facilement déprotonés pour donner des tensioactifs anioniques tels que le laureth sulfate de sodium. Étant des sels, les éthoxysulfates présentent une bonne solubilité dans l’eau (valeur HLB élevée). La conversion est obtenue en traitant le Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcool alcoxylé) avec du trioxyde de soufre. [11] La synthèse à l’échelle du laboratoire peut être réalisée à l’aide d’acide chlorosulfurique:

R (OC2H4) nOH + SO3 → R (OC2H4) nOSO3H

R (OC2H4) nOH + HSO3Cl → R (OC2H4) nOSO3H + HCl

Les esters de sulfate résultants sont neutralisés pour donner le sel:

R (OC2H4) nOSO3H + NaOH → R (OC2H4) nOSO3Na + H2O

De petits volumes sont neutralisés avec des alcanolamines telles que la triéthanolamine (TEA). En 2006, 382 500 tonnes métriques d’éthoxysulfates d’alcool (Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcool alcoxylé)) ont été consommées en Amérique du Nord.

Autres matériaux

Bien que les alcools soient de loin le substrat principal du Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG), de nombreux nucléophiles sont réactifs envers l’oxyde d’éthylène. Les amines primaires réagiront pour donner des matériaux di-chaîne tels qu’une amine de suif polyéthoxylée. La réaction de l’ammoniac produit d’importants produits chimiques en vrac tels que l’éthanolamine, la diéthanolamine et la triéthanolamine.

Applications des produits éthoxylés

Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (AE) et les éthoxysulfates d’alcool (Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcool alcoxylé)) sont des tensioactifs présents dans des produits tels que les détergents à lessive, les nettoyants de surface, les cosmétiques, les produits agricoles, les textiles et la peinture.

Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG)

Comme les tensioactifs à base de Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcool alcoxylé) ne sont pas ioniques, ils nécessitent généralement des chaînes éthoxylées plus longues que leurs analogues sulfonés pour être solubles dans l’eau. [15] Des exemples synthétisés à l’échelle industrielle comprennent l’éthoxylate d’octylphénol, le polysorbate 80 et les poloxamères. Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) est couramment pratiqué, quoique à une échelle beaucoup plus petite, dans les industries biotechnologiques et pharmaceutiques pour augmenter la solubilité dans l’eau et, dans le cas des produits pharmaceutiques, la demi-vie circulatoire des composés organiques non polaires. Dans cette application, Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) est connu sous le nom de «PEGylation» (l’oxyde de polyéthylène est synonyme de polyéthylène glycol, abrégé en PEG). La longueur de la chaîne de carbone est de 8 à 18, tandis que la chaîne éthoxylée est généralement de 3 à 12 oxydes d’éthylène dans les produits ménagers. [16] [page nécessaire] Ils comportent à la fois des queues lipophiles, indiquées par l’abréviation du groupe alkyle, R, et des groupes de tête relativement polaires, représenté par la formule (OC2H4) nOH.

Ethoxysulfates d’alcool

Le Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcool alcoxylé) trouvé dans les produits de consommation est généralement des alcools linéaires, qui pourraient être des mélanges de chaînes alkyles entièrement linéaires ou de chaînes alkyles linéaires et monobranchées. Un exemple à grand volume de ceux-ci est le laureth sulfate de sodium, un agent moussant dans les shampooings et les savons liquides, ainsi que dans les détergents industriels.

Santé humaine pour Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG)

Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) ne semble pas être mutagène, cancérigène ou sensibilisant cutané, ni causer d’effets sur la reproduction ou le développement. [18] Un sous-produit de Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) est le 1,4-dioxane, un cancérogène possible pour l’homme. [19] Le Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) non dilué (alcool alcoxylé) peut provoquer une irritation cutanée ou oculaire. En solution aqueuse, le niveau d’irritation dépend de la concentration. Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcool alcoxylé) est considéré comme ayant une toxicité faible à modérée pour une exposition orale aiguë, une faible toxicité cutanée aiguë et un potentiel d’irritation légère de la peau et des yeux à des concentrations trouvées dans les produits de consommation.

Aspects aquatiques et environnementaux

Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcool alcoxylé) sont généralement rejetés dans les égouts, où ils peuvent être adsorbés dans les solides et se biodégrader par des processus anaérobies, avec ~ 28 à 58% dégradés dans les égouts. [20] [source non primaire nécessaire] Le Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcool alcoxylé) restant est traité dans les stations d’épuration des eaux usées et biodégradé par des procédés aérobies avec moins de 0,8% de Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcool alcoxylé) rejeté dans l’effluent. [20 ] S’il est rejeté dans les eaux de surface, les sédiments ou le sol, le Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcool alcoxylé) se dégradera par des processus aérobies et anaérobies ou sera absorbé par les plantes et les animaux.

La toxicité pour certains invertébrés a une plage de valeurs CE50 pour l’EI linéaire de 0,1 mg / l à plus de 100 mg / l. Pour les exthoxylates d’alcools ramifiés, la toxicité varie de 0,5 mg / l à 50 mg / l. [16] La toxicité CE50 pour les algues du Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcool alcoxylé) linéaire et ramifié était de 0,05 mg / l à 50 mg / l. La toxicité aiguë pour les poissons va de valeurs CL50 pour AE linéaire de 0,4 mg / l à 100 mg / l, et ramifiée est de 0,25 mg / l à 40 mg / l. Pour les invertébrés, les algues et les poissons, les Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcool alcoxylé) essentiellement linéaires et ramifiés ne sont pas considérés comme ayant une plus grande toxicité que les AE linéaires.

Biodégradation de Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG)

La dégradation du Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcool alcoxylé) se fait par ω- ou β-oxydation de la chaîne alkyle, hydrolyse enzymatique de l’ester sulfate, et par clivage d’une liaison éther dans le Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcool alcoxylé) produisant de l’alcool ou du Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcool alcoxylé) et un sulfate d’éthylène glycol. Des études sur les processus aérobies ont également révélé que le Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcool alcoxylé) était facilement biodégradable. [12] On estime que la demi-vie d’AE et de Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcool alcoxylé) dans l’eau de surface est inférieure à 12 heures. L’AG (alcool alcoxylé) dû à la dégradation par des processus anaérobies est estimé entre 75 et 87%.

Sécurité humaine de Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG)

Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcool alcoxylé) ne s’est pas révélé génotoxique, mutagène ou cancérigène.

Les alcools en C8-10, éthoxylés, propoxylés (Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG)) sont un petit sous-ensemble d’éthoxylates d’alcool qui ont de nombreuses applications, mais sont principalement utilisés dans les détergents et comme tensioactifs car ils sont particulièrement efficaces pour éliminer les salissures huileuses. Ils sont également utilisés dans les nettoyants commerciaux et résidentiels (3) et la fracturation hydraulique.

Les Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (éthoxylate d’alcool) sont une classe de composés couramment utilisés dans de nombreuses pratiques industrielles et marchés commerciaux. Ces composés sont synthétisés via la réaction d’un alcool gras et de l’oxyde d’éthylène, donnant une molécule qui se compose de deux composants principaux, (1) l’alcool gras oléophile riche en carbone et (2) la chaîne polyoxyéthylène hydrophile.

En raison de la structure de base de ces composés qui associent une partie hydrophobe (détestant l’eau) à un composant hydrophile (aimant l’eau), les Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (éthoxylate d’alcool) sont une classe polyvalente de composés, communément appelés tensioactifs. Les tensioactifs Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (éthoxylate d’alcool) améliorent le mélange et la solubilisation de l’huile et de l’eau en ayant ces sections contrastées dans le même composé. Avec cette structure unique, une seule molécule peut habiter l’interface de deux phases non miscibles (c’est-à-dire l’huile et l’eau), les rapprochant efficacement et abaissant l’énergie interfaciale associée entre elles. En abaissant cette énergie, de nombreuses applications de solutions novatrices sont accessibles en augmentant l’homogénéité de ces deux phases auparavant non miscibles.

Qu’est-ce que Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (éthoxylate d’alcool)?

Les Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (éthoxylate d’alcool) peuvent varier considérablement dans leurs propriétés et leurs applications car les matériaux utilisés pour fabriquer ces produits peuvent varier dans leurs structures et leurs quantités. Par exemple, les alcools gras, qui proviennent généralement de matières naturelles, peuvent fournir des structures différentes selon la plante dont ils ont été extraits. Les sources naturelles courantes d’alcools gras comprennent le palmier à huile (y compris l’huile de palme et l’huile de palmiste), les huiles de cocotier et l’huile de colza. Chacune de ces sources naturelles diffère dans sa distribution de chaînes carbonées, ce qui rend un Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcool éthoxylé) à partir d’alcool d’huile de coco différent d’un Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (éthoxylate d’alcool) fabriqué à partir de l’alcool d’un l’huile de palmiste.

Oxiteno propose une large gamme de Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (éthoxylate d’alcool) provenant de matériaux naturels (Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (éthoxylate d’alcool)), chacun offrant un ensemble unique de propriétés d’application . De plus, les alcools gras peuvent également être synthétisés à partir de produits pétroliers, fournissant des structures uniques dans le groupement hydrophobe qui ne sont pas couramment observées dans la nature. Les alcools ramifiés et les alcools de distributions spécifiques de carbone peuvent être obtenus en utilisant des matières premières synthétiques, qui affectent toutes fortement les propriétés finales du Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (alcool éthoxylate).

En variante, la longueur du composant polyoxyéthylène (c’est-à-dire la partie hydrophile) du Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (éthoxylate d’alcool) fournit à cette classe de composés un large assortiment de solubilités dans l’eau et de propriétés détergentes. L’augmentation de la quantité d’oxyde d’éthylène sur le Greenbentin-SG/854/AG (GREENBENTIN-SG/854/AG) (éthoxylate d’alcool) augmente généralement sa solubilité dans l’eau, ainsi que l’équilibre hydrophile / lipophile (HLB) du composé. Dans des unités arbitraires de 1 à 20, le HLB d’un tensioactif non ionique peut être calculé et utilisé pour déterminer la propension d’un composé à travailler efficacement dans une solution donnée d’huile et d’eau. Des valeurs HLB inférieures (<10) sont couramment utilisées pour les solutions riches en huile, tandis que les tensioactifs avec des valeurs HLB plus élevées (> 10) sont généralement plus efficaces dans les émulsions huile dans eau.
