Structure

Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) (SLES) is in the family of organosulfate compounds,[2] and has the formula, CH3(CH2)11SO4Na. It consists of a 12-carbon tail attached to a sulfate group, that is, it is the sodium salt of a 12-carbon alcohol that has been esterified to sulfuric acid. An alternative description is that it is an alkyl group with a pendant, terminal sulfate group attached. As a result of its hydrocarbon tail, and its anionic “head group”, it has amphiphilic properties that allow it to form micelles, and so act as a detergent.

Physicochemical properties

The critical micelle concentration (CMC) in pure water at 25 °C is 8.2 mM,[1] and the aggregation number at this concentration is usually considered to be about 62.[3] The micelle ionization fraction (α) is around 0.3 (or 30%).[4]

Production

Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) (SLES) is synthesized by treating lauryl alcohol with sulfur trioxide gas, oleum, or chlorosulfuric acid to produce hydrogen lauryl sulfate.[5] The resulting product is then neutralized through the addition of sodium hydroxide or sodium carbonate.[citation needed] Lauryl alcohol can be used in pure form or may be derived from either coconut or palm kernel oil by hydrolysis (which liberates their fatty acids), followed by hydrogenation.[citation needed] When produced from these sources, commercial samples of these “Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) (SLES) ” products are actually not pure Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) (SLES) , rather a mixture of various sodium alkyl sulfates with Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) (SLES) being the main component.[6] For instance, Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) (SLES) is a component, along with other chain-length amphiphiles, when produced from coconut oil, and is known as sodium coco sulfate (SCS).[7] Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) (SLES) is available commercially in powder, pellet, and other forms (each differing in rates of dissolution), as well as in aqueous solutions of varying concentrations.

Laboratory applications

Principal applications

Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%), in science referred to as sodium dodecyl sulfate (Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) (SLES) ), is used in cleaning procedures, and is commonly used as a component for lysing cells during RNA extraction and/or DNA extraction, and for denaturing proteins in preparation for electrophoresis in the Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) (SLES) -PAGE technique. In the case of the Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) (SLES) -PAGE application, the compound works by disrupting non-covalent bonds in the proteins, and so denaturing them, i.e., causing the protein molecules to lose their native conformations and shapes.[citation needed] By binding to the proteins with high affinity and in high concentrations, the negatively charged detergent provides all proteins with a similar net negative charge and therefore a similar charge-to-mass ratio. In this way, the difference in mobility of the polypeptide chains in the gel can be attributed solely to their size as opposed to both their size and charge.[16] It is possible to make separation based on the size of the polypeptide chain to simplify the analysis of protein molecules, this can be achieved by denaturing proteins with the detergent Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) (SLES) .The association of Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) (SLES) molecules with protein molecules imparts an associated negative charge to the molecular aggregate formed;[citation needed] this negative charge is significantly greater than the original charge of that protein.[citation needed] The electrostatic repulsion that is created by Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) binding forces proteins into a rod-like shape, thereby eliminating differences in shape as a factor for electrophoretic separation in gels.[citation needed] Dodecyl sulfate molecule has two negative charges at the pH value used for electrophoresis, this will lead the net charge of coated polypeptide chains to be much more negative than uncoated chains.[17] The charge-to-mass ratio is essentially identical for different proteins because Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) (SLES) coating dominates the charge.

Miscellaneous applications

Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) is used in an improved technique for preparing brain tissues for study by optical microscopy. The technique, which has been branded as CLARITY, was the work of Karl Deisseroth and coworkers at Stanford University, and involves infusion of the organ with an acrylamide solution to bind the macromolecules of the organ (proteins, nucleic acids, etc.), followed by thermal polymerization to form a “brain-hydrogel” (a mesh interspersed throughout the tissue to fix the macromolecules and other structures in space), and then by lipid removal using Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) (SLES) to eliminate light scattering with minimal protein loss, rendering the tissue quasi-transparent. Along with sodium dodecylbenzene sulfonate and Triton X-100, aqueous solutions of Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) (SLES) are popular for dispersing or suspending nanotubes, such as carbon nanotubes.

In products intended for prolonged contact with skin, concentrations should not exceed 1%.”:89ff

Sensitivity

Like all detergent surfactants, Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) removes oils from the skin, and can cause skin and eye irritation.[citation needed] It has been shown to irritate the skin of the face, with prolonged and constant exposure (more than an hour) in young adults.Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) (SLES) may worsen skin problems in individuals with chronic skin hypersensitivity, with some people being affected more than others.

Oral concerns

The low cost of Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) (SLES) , its lack of impact on taste, its potential impact on volatile sulfur compounds (VSCs, which contribute to malodorous breath),[35] and its desirable action as a foaming agent have led to the use of Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) (SLES) in the formulations of toothpastes.A series of small crossover studies (25-34 patients) have supported the efficacy of Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) (SLES) in the reduction of VSCs, and its related positive impact on breath malodor, although these studies have been generally noted to reflect technical challenges in the control of study design variables. While primary sources from the group of Irma Rantanen at University of Turku, Finland conclude an impact on dry mouth (xerostomia) from Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) (SLES) -containing pastes, a 2011 Cochrane review of these studies, and of the more general area, concludes that there “is no strong evidence… that any topical therapy is effective for relieving the symptom of dry mouth.”[36] A safety concern has been raised on the basis of several studies regarding the effect of toothpaste Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) (SLES) on aphthous ulcers, commonly referred to as canker or white sores. A consensus regarding practice (or change in practice) has not appeared as a result of the studies. As Lippert notes, of 2013, “very few… marketed toothpastes contain a surfactant other than Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) (SLES) [Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) (SLES) ],” and leading manufacturers continue to formulate their produce with Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) (SLES) .

Interaction with fluoride

Some studies have suggested that Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) (SLES) in toothpaste may decrease the effectiveness of fluoride at preventing dental caries (cavities). This may be due to Sodium lauryl ether sulphate 28% (Sodyum lauril eter sülfat %28, SODIUM LAURYL ETHER SULPHATE 28%) (SLES) interacting with the deposition of fluoride on tooth enamel.

Structure

Le lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES) appartient à la famille des composés organosulfates, [2] et répond à la formule CH3 (CH2) 11SO4Na. Il se compose d’une queue de 12 carbones attachée à un groupe sulfate, c’est-à-dire du sel de sodium d’un alcool à 12 carbones qui a été estérifié en acide sulfurique. Une description alternative est qu’il s’agit d’un groupe alkyle avec un groupe sulfate terminal pendant. Du fait de sa queue d’hydrocarbure, et de son «groupe de tête» anionique, il possède des propriétés amphiphiles qui lui permettent de former des micelles, et donc d’agir comme un détergent.

Propriétés physicochimiques

La concentration micellaire critique (CMC) dans l’eau pure à 25 ° C est de 8,2 mM, [1] et le nombre d’agrégation à cette concentration est généralement considéré comme d’environ 62. [3] La fraction d’ionisation micellaire (α) est d’environ 0,3 (soit 30%).

Le lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES) est synthétisé en traitant l’alcool laurique avec du trioxyde de soufre gazeux, de l’oléum ou de l’acide chlorosulfurique pour produire de l’hydrogène lauryl sulfate. [5] Le produit résultant est ensuite neutralisé par l’ajout d’hydroxyde de sodium ou de carbonate de sodium. [La citation nécessaire] L’alcool laurylique peut être utilisé sous forme pure ou peut être dérivé de l’huile de noix de coco ou de palmiste par hydrolyse (qui libère leurs acides gras), suivi par hydrogénation. [citation nécessaire] Lorsqu’ils sont produits à partir de ces sources, des échantillons commerciaux de ces produits “sodium lauryl éther sulfate 28% (SLES)” ne sont en fait pas du sodium lauryl éther sulfate 28% pur (SLES), plutôt un mélange de divers alkyles de sodium sulfates, le lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES) étant le composant principal. [6] Par exemple, le lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES) est un composant, avec d’autres amphiphiles à chaîne, lorsqu’il est produit à partir d’huile de noix de coco, et est connu sous le nom de coco sulfate de sodium (SCS). [7] Le lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES) est disponible dans le commerce sous forme de poudre, de pastille et d’autres formes (chacune différant par des taux de dissolution), ainsi que dans des solutions aqueuses de concentrations variables.

Applications de laboratoire

Principales applications

Le lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%), appelé dans la science le dodécyl sulfate de sodium (sodium lauryl éther sulfate 28% (SLES)), est utilisé dans les procédures de nettoyage et est couramment utilisé comme composant pour la lyse des cellules lors de l’extraction d’ARN et / ou d’ADN extraction, et pour dénaturer les protéines en préparation pour l’électrophorèse dans la technique de lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES) -PAGE. Dans le cas de l’application Sodium lauryl éther sulfate 28% (SLES) -PAGE, le composé agit en perturbant les liaisons non covalentes dans les protéines, et ainsi en les dénaturant, c’est-à-dire en faisant perdre aux molécules de protéines leurs conformations et formes natives. [la citation nécessaire] En se liant aux protéines avec une affinité élevée et à des concentrations élevées, le détergent chargé négativement fournit à toutes les protéines une charge négative nette similaire et donc un rapport charge-masse similaire. De cette manière, la différence de mobilité des chaînes polypeptidiques dans le gel peut être attribuée uniquement à leur taille par opposition à leur taille et à leur charge. [16] Il est possible de faire une séparation en fonction de la taille de la chaîne polypeptidique pour simplifier l’analyse des molécules de protéines, ceci peut être réalisé en dénaturant les protéines avec le détergent Sodium lauryl éther sulfate 28% (SLES). L’association Sodium lauryl éther sulfate 28 % (SLES) molécules avec des molécules de protéine confère une charge négative associée à l’agrégat moléculaire formé; [citation nécessaire] cette charge négative est significativement plus grande que la charge originale de cette protéine. [Citation nécessaire] La répulsion électrostatique qui est créée par Sodium lauryl la liaison du sulfate d’éther à 28% force les protéines en forme de bâtonnet, éliminant ainsi les différences de forme en tant que facteur de séparation électrophorétique dans les gels. [la citation nécessaire] La molécule de sulfate de dodécyle a deux charges négatives à la valeur de pH utilisée pour l’électrophorèse, la charge nette des chaînes polypeptidiques enrobées est beaucoup plus négative que les chaînes non enrobées. [17] Le rapport charge / masse est essentiellement identique pour différentes protéines car le revêtement de lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES) domine la charge.

Applications diverses

Le lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) est utilisé dans une technique améliorée de préparation des tissus cérébraux à étudier par microscopie optique. La technique, qui a été qualifiée de CLARITY, a été le travail de Karl Deisseroth et de ses collègues de l’Université de Stanford, et implique l’infusion de l’organe avec une solution d’acrylamide pour lier les macromolécules de l’organe (protéines, acides nucléiques, etc.), suivie par polymérisation thermique pour former un “cerveau-hydrogel” (un maillage intercalé dans tout le tissu pour fixer les macromolécules et autres structures dans l’espace), puis par élimination des lipides à l’aide du lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES) pour éliminer la diffusion de la lumière avec un minimum perte de protéines, rendant le tissu quasi-transparent. Avec le dodécylbenzène sulfonate de sodium et le Triton X-100, les solutions aqueuses de lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES) sont populaires pour disperser ou mettre en suspension des nanotubes, tels que des nanotubes de carbone.

Utilisations de niche

Le lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES) a été proposé comme microbicide topique potentiellement efficace, à usage intravaginal, pour inhiber et éventuellement prévenir l’infection par divers virus enveloppés et non enveloppés tels que les virus de l’herpès simplex, le VIH et la forêt de Semliki virus. Dans les expériences de formation d’hydrate de gaz, le sulfate de lauryléther de sodium 28% (SLES) est utilisé comme promoteur de croissance d’hydrate de gaz.Les chercheurs visent des promotions d’hydrate de gaz à l’échelle des applications industrielles d’hydrates de gaz telles que le processus de dessalement, le stockage de gaz et le gaz technologies de séparation. Il a été démontré que les membranes liquides formées à partir de sulfate de lauryléther de sodium à 28% (SLES) dans l’eau fonctionnent comme des séparateurs de particules inhabituels.

Toxicologie

Cancérogénicité

Le lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES) n’est pas cancérigène lorsqu’il est consommé ou appliqué directement, même à des quantités et des concentrations qui dépassent les quantités utilisées dans les produits commerciaux standard.L’examen précédent du groupe d’experts du programme Cosmetic Ingredient Review (CIR) en 1983 a rapporté que Sodium lauryl éther sulfate 28% (SLES) (là, abrégé Sodium lauryl éther sulfate 28% (SLES), pour Sodium lauryl éther sulfate 28%) à des concentrations allant jusqu’à 2%, au cours d’un an d’études alimentaires orales chez le chien, a donné aucune preuve de tumorigénicité ou de carcinogénicité, et qu’aucun excès d’aberrations chromosomiques ou d’effets clastogènes n’a été observé chez les rats nourris à hauteur de 1,13% de lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) dans leur alimentation pendant 90 jours, par rapport à ceux d’un régime témoin. [28]: 157 , 175 L’examen de 2005 par le même groupe a indiqué que d’autres données disponibles manquaient de toute suggestion disponible que le lauryl éther sulfate de sodium 28% (SLES) ou le sel d’ammonium apparenté du même amphiphile pourrait être cancérigène, déclarant tha «Malgré les affirmations contraires sur Internet, la cancérogénicité de ces ingrédients n’est qu’une rumeur»; les deux études concluent que le lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES) semble «être sans danger dans les formulations conçues pour une utilisation discontinue et brève suivie d’un rinçage complet à la surface de la peau. Dans les produits destinés à un contact prolongé avec la peau, les concentrations ne doivent pas dépasser 1%. “: 89ff

Sensibilité

Comme tous les tensioactifs détergents, le lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) élimine les huiles de la peau et peut provoquer une irritation de la peau et des yeux. [Citation nécessaire] Il a été démontré qu’il irritait la peau du visage, avec une exposition prolongée et constante (plus d’un heure) chez les jeunes adultes.

Préoccupations orales

Le faible coût du lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES), son absence d’impact sur le goût, son impact potentiel sur les composés soufrés volatils (CSV, qui contribuent à l’haleine malodorante), [35] et son action souhaitable comme agent moussant ont a conduit à l’utilisation du lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES) dans les formulations de dentifrices.Une série de petites études croisées (25-34 patients) ont soutenu l’efficacité du lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES) dans la réduction de Les CSV et leur impact positif connexe sur la mauvaise odeur respiratoire, bien que ces études aient généralement été considérées comme reflétant des défis techniques dans le contrôle des variables de conception de l’étude. Alors que les sources primaires du groupe d’Irma Rantanen de l’Université de Turku, la Finlande concluent à un impact sur la bouche sèche (xérostomie) des pâtes contenant du lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES), une revue Cochrane de 2011 de ces études, et de domaine général, conclut qu’il n’y a «aucune preuve solide … qu’une thérapie topique soit efficace pour soulager le symptôme de la bouche sèche.» [36] Un problème de sécurité a été soulevé sur la base de plusieurs études concernant l’effet du dentifrice Sodium lauryl éther sulfate 28% (SLES) sur les ulcères aphteux, communément appelés chancres ou plaies blanches. Un consensus sur la pratique (ou le changement de pratique) n’est pas apparu à la suite des études. Comme le note Lippert, en 2013, “très peu … de dentifrices commercialisés contiennent un tensioactif autre que le lauryl éther sulfate de sodium 28% (SLES) [sodium lauryl éther sulfate 28% (SLES)]», et les principaux fabricants continuent de formuler leurs produits avec du lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES).

Interaction avec le fluorure

Certaines études ont suggéré que le lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES) dans le dentifrice peut diminuer l’efficacité du fluor pour prévenir les caries dentaires (caries). Cela peut être dû à l’interaction du lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES) avec le dépôt de fluorure sur l’émail des dents.

Aperçu

Le lauryl éther sulfate de sodium 28% (sulfate lauryl éther sodique 28% (SLES)) est l’un des ingrédients que vous trouverez sur votre bouteille de shampoing. Cependant, à moins que vous ne soyez chimiste, vous ne savez probablement pas ce que c’est. Le produit chimique se trouve dans de nombreux produits de nettoyage et de beauté, mais il est souvent mal compris.

Les mythes urbains l’ont lié au cancer, à l’irritation de la peau, etc. La science peut raconter une histoire différente.

Comment ça fonctionne

Le lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES) est ce qu’on appelle un «surfactant». Cela signifie qu’il abaisse la tension superficielle entre les ingrédients, c’est pourquoi il est utilisé comme agent nettoyant et moussant.

La plupart des préoccupations concernant le lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES) proviennent du fait qu’il peut être trouvé dans les produits de beauté et d’auto-soins ainsi que dans les nettoyants ménagers.

Le lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES) est un surfactant de formule chimique similaire. Cependant, le SLES est plus doux et moins irritant que le lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES).

Où vous trouverez le lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES)

Si vous regardez sous le lavabo de votre salle de bain ou sur l’étagère de votre douche, vous trouverez très probablement du lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES) dans votre maison. Il est utilisé dans une variété de produits, notamment:

Produits de soin, tels que la crème à raser, le baume à lèvres, le désinfectant pour les mains, les traitements pour les ongles, le démaquillant, le fond de teint, les nettoyants pour le visage, les exfoliants et le savon liquide pour les mains

Produits capillaires, tels que shampooing, revitalisant, colorant capillaire, traitement antipelliculaire et gel coiffant

Produits de soins dentaires, tels que dentifrice, produits de blanchiment des dents et bain de bouche

Produits de bain, tels que huiles ou sels de bain, gel douche et bain moussant

Crèmes et lotions, comme la crème pour les mains, les masques, les crèmes anti-démangeaisons, les produits d’épilation et les écrans solaires

Vous remarquerez que tous ces produits sont topiques ou appliqués directement sur la peau ou le corps.

Le lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES) est également utilisé comme additif alimentaire, généralement comme émulsifiant ou épaississant. Il peut être trouvé dans les produits à base d’œufs séchés, certains produits à base de guimauve et certaines bases de boissons sèches.

Y a-t-il des dangers?

La Food and Drug Administration (FDA) considère que le lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES) est aussi sûr qu’un additif alimentaire.

En ce qui concerne son utilisation dans les cosmétiques et les produits pour le corps, l’étude d’évaluation de la sécurité du lauryl éther sulfate de sodium 28% (SLES), publiée en 1983 dans l’International Journal of Toxicology (l’évaluation la plus récente), a révélé qu’il n’est pas nocif s’il est utilisé brièvement et rincé de la peau, comme avec les shampooings et les savons.

Le rapport indique que les produits qui restent sur la peau plus longtemps ne doivent pas dépasser 1% de concentration de sodium lauryl éther sulfate 28% (SLES).

Cependant, la même évaluation a suggéré un risque possible, quoique minime, pour les humains en utilisant le lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES). Par exemple, certains tests ont montré qu’une exposition cutanée continue au lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES) pouvait provoquer une irritation légère à modérée chez les animaux.

Néanmoins, l’évaluation a conclu que le lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES) est sans danger dans les formulations utilisées dans les cosmétiques et les produits de soins personnels. Étant donné que bon nombre de ces produits sont conçus pour être rincés après de courtes applications, les risques sont minimes.

Selon la plupart des recherches, le lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES) est un irritant mais pas un cancérigène. Des études n’ont montré aucun lien entre l’utilisation du lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES) et un risque accru de cancer.

Selon une étude de 2015, le lauryléther sulfate de sodium 28% (Sodium lauryl ether sulphate 28%) (SLES) peut être utilisé sans danger dans les produits de nettoyage ménagers.
