Functions of PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate):
PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) is used in cosmetics and beauty products primarily as a surfactant and cleansing agent, because PEG Stearates’ ability to clean the skin and hair by helping water to mix with oil and dirt so that they can be rinsed away, according to CosmeticsInfo.org. However, it is also seen as an emollient, because of secondary properties.
Unlike typical PEGs, (whose identifying number corresponds to their molecular weight) the numerical value of each PEG Stearate corresponds to the average number of ethylene oxide monomers in the polyethylene chain (from 2 – 150).
Despite the many fears regarding PEGs, they are seen as an ingredient in a large number of products because of their diverse properties. In a study published in the Toxicology journal in 2005, entitled “Safety assessment on polyethylene glycols (PEGs) and their derivatives as used in cosmetic products,” it was concluded that: “Taking into consideration all available information from related compounds, as well as the mode and mechanism of action, no safety concern with regard to these endpoints could be identified. Based on the available data it is therefore concluded that PEGs of a wide molecular weight range (200 to over 10,000), their ethers (laureths. ceteths, ceteareths, steareths, and oleths), and fatty acid esters (laurates, dilaurates, stearates, distearates) are safe for use in cosmetics.”
PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) is not considered to be an irritant or sensitizer (it gave only minimal irritation in studies up to 100%), and are CIR and FDA approved for use, but not on broken skin (Source).
Safety Measures/Side Effects of PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE):
However. The Cosmetics Database found PEG 40 Stearate to be a moderate to high hazard ingredient depending on usage. The EWG issues warnings regarding: cancer, developmental and reproductive toxicity, contamination concerns, irritation, and organ system toxicity.
According to a study published in the International Journal of Toxicology, PEGs (including PEG 40 Stearate) can contain harmful impurities, including: Ethylene Oxide, known to increase the incidences of uterine and breast cancers and of leukemia and brain cancer, according to experimental results reported by the National Toxicology Program; 1,4-dioxane, a known carcinogen; PAHs, known to increase the risk of breast cancer; lead; iron; and arsenic (Source).
Products and formulas containing PEG 40 Stearate should not be used on broken or irritated skin. Although PEGs are considered safe for use topically on healthy skin, studies showed that patients suffering from severe burns were treated with PEG-based antimicrobial cream; this treatment resulted in kidney toxicity. “The PEG content of the antimicrobial cream was determined to be the causative agent. However, no evidence of systemic toxicity occurred in studies with intact skin. Because of the observation of kidney effects in burn patients, the CIR Expert Panel qualified their conclusion on the safety of the PEG ingredients to state that cosmetic formulations containing these ingredients should not be used on damaged skin”

Polyoxyethylene 40 monostearate, also known as ethylene glycol monostearate or myrj 52, belongs to the class of organic compounds known as fatty acid esters. These are carboxylic ester derivatives of a fatty acid. Polyoxyethylene 40 monostearate is considered to be a practically insoluble (in water) and relatively neutral molecule. Polyoxyethylene 40 monostearate has been primarily detected in urine. Within the cell, polyoxyethylene 40 monostearate is primarily located in the membrane (predicted from logP) and cytoplasm.
A sample work-up method for gas chromatographic profiling of polyethylene glycol related cmpd in pharmaceutical matrixes is described. After a short sample clean-up, carbon-oxygen linkages were partially cleaved with 0.07/M BBr3 in CH2Cl2 at room temp. The reaction was stopped after 1 min by addn of 0.01M hydrochloric acid. The products were trimethylsilylated and injected onto a WCOT 50 m X 0.25 mm CP-SIL 5 CB fused silica column. Eleven model cmpd, representing 4 common types of polyethylene glycol deriv, were evaluated by this method. Characteristic profiles can be obtained from polyethylene glycol deriv carrying different functional groups. Minimum detectable amt are in the range of 200 ug.
Polyoxyl 40 Stearate is used in cosmetics and beauty products primarily as a surfactant and emulsifier. It occurs naturally as a white, waxy or flaky substance, according to The Food and Agriculture Organization of the United Nations.

Health effects of PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate)
PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate) is considered biologically inert and safe by the FDA. However, a growing body of evidence shows the existence of anti PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate) antibodies in approximately 72% of the population based on plasma samples from 1990-1999.[medical citation needed] The FDA has been asked to investigate the possible effects of PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate) in laxatives for children.[29]
Due to its ubiquity in a multitude of products and the large percentage of the population with antibodies to PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate), hypersensitive reactions to PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate) are an increasing concern.[medical citation needed] Allergy to PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate) is usually discovered after a person has been diagnosed with an allergy to an increasing number of seemingly unrelated products, including processed foods, cosmetics, drugs, and other substances that contain PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate) or were manufactured with PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate).[30]
When PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate) is chemically attached to therapeutic molecules (such as protein drugs or nanoparticles), it can sometimes be antigenic, stimulating an anti-PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate) antibody response in some patients. This effect has only been shown for a few of the many available PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate)ylated therapeutics, but it has significant effects on clinical outcomes of affected patients.[31] Other than these few instances where patients have anti-PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate) immune responses, it is generally considered to be a safe component of drug formulations.
Available forms and nomenclature of PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate)
PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate), PEO, and POE refer to an oligomer or polymer of ethylene oxide. The three names are chemically synonymous, but historically PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate) is preferred in the biomedical field, whereas PEO is more prevalent in the field of polymer chemistry. Because different applications require different polymer chain lengths, PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate) has tended to refer to oligomers and polymers with a molecular mass below 20,000 g/mol, PEO to polymers with a molecular mass above 20,000 g/mol, and POE to a polymer of any molecular mass.[32] PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate)s are prepared by polymerization of ethylene oxide and are commercially available over a wide range of molecular weights from 300 g/mol to 10,000,000 g/mol.[33]
PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate) and PEO are liquids or low-melting solids, depending on their molecular weights. While PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate) and PEO with different molecular weights find use in different applications, and have different physical properties (e.g. viscosity) due to chain length effects, their chemical properties are nearly identical. Different forms of PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate) are also available, depending on the initiator used for the polymerization process – the most common initiator is a monofunctional methyl ether PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate), or methoxypoly(ethylene glycol), abbreviated mPEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate). Lower-molecular-weight PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate)s are also available as purer oligomers, referred to as monodisperse, uniform, or discrete. Very high purity PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate) has recently been shown to be crystalline, allowing determination of a crystal structure by x-ray diffraction.[33] Since purification and separation of pure oligomers is difficult, the price for this type of quality is often 10-1000 fold that of polydisperse PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate).

Polyethylene glycol 40, pharmaceutical quality
Polyethylene glycol 40, pharmaceutical quality
The production of polyethylene glycol was first reported in 1859. Both independently isolated products that were polyethylene glycols.[38] Polyethylene glycol is produced by the interaction of ethylene oxide with water, ethylene glycol, or ethylene glycol oligomers.[39] The reaction is catalyzed by acidic or basic catalysts. Ethylene glycol and its oligomers are preferable as a starting material instead of water, because they allow the creation of polymers with a low polydispersity (narrow molecular weight distribution). Polymer chain length depends on the ratio of reactants.
HOCH2CH2OH + n(CH2CH2O) → HO(CH2CH2O)n+1H
Depending on the catalyst type, the mechanism of polymerization can be cationic or anionic. The anionic mechanism is preferable because it allows one to obtain PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate) with a low polydispersity. Polymerization of ethylene oxide is an exothermic process. Overheating or contaminating ethylene oxide with catalysts such as alkalis or metal oxides can lead to runaway polymerization, which can end in an explosion after a few hours.
Polyethylene oxide, or high-molecular weight polyethylene glycol, is synthesized by suspension polymerization. It is necessary to hold the growing polymer chain in solution in the course of the polycondensation process. The reaction is catalyzed by magnesium-, aluminium-, or calcium-organoelement compounds. To prevent coagulation of polymer chains from solution, chelating additives such as dimethylglyoxime are used.
Alkaline catalysts such as sodium hydroxide (NaOH), potassium hydroxide (KOH), or sodium carbonate (Na2CO3) are used to prepare low-molecular-weight polyethylene glycol.

Usage comme solvant en chimie du PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate)
À température ambiante, le PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate) est un liquide visqueux incolore lorsqu’il a une masse moléculaire inférieure à 600 g·mol-1 et un solide cireux lorsque sa masse moléculaire est supérieur à 800 g·mol-1. Le PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate) liquide est miscible en toute proportion avec l’eau tandis que le PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate) solide est hautement soluble dans l’eau. Le PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate) de faible masse moléculaire peut donc être utilisé comme solvant polymère, c’est-à-dire un polymère qui agit comme solvant pour des composés de faible masse molaire5, avec ou sans ajout d’eau. Le PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate) peut ainsi dissoudre des sels inorganiques divers par complexation. De plus, la viscosité du PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate) diminue lorsque la température augmente. Pour le PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate)-1000, la température de fusion se situe vers 35-40 °C, et pour le PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate)-2000, la température de fusion se situe vers 44-45 °C.

Les catalyseurs de transfert de phase (PTC) sont utilisés pour transporter un réactif aqueux dans la phase organique dans un état activé la réaction peut avoir lieu entre un réactif aqueux et un réactif organique. Le PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate) a la capacité de servir comme PTC car les chaînes polyéthylène peuvent former des complexes avec les cations métalliques comme les éthers couronnes. Les solutions de PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate) ont une habilité à coordonner les cations. Pour maintenir l’électroneutralité des complexes PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate)-cations métalliques doivent apporter un équivalent d’anion dans la phase organique et rendent l’anion disponible pour la réaction avec les réactifs organiques. L’activité catalytique du PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate) dépend de la masse moléculaire et de la nature des cations et des anions. Le PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate) et de nombreux dérivés ont été utilisés comme PTC pour remplacer les PTC onéreux et toxiques. Le PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate) est moins cher que les éthers couronnes, les cryptants et plus stable aux hautes températures. Pour ces différentes raisons, le PEG 40 STEARATE (POLYOXYETHYLENE 40 STEARATE) (Polioksietilen 40 stearat) (Polyoxyl 40 stearate) a été utilisé comme PTC dans des SN, des oxydations des réactions de Williamson.
