Foaming properties are actually added to meet a consumer demand [20]. CAS number: 151-21-3. However, the same process that makes SLES a less irritating ingredient than SLS exposes it to a known carcinogen, 1,4-dioxane. Its properties are similar to those of its non-ether cousin,sodium lauryl sulfate(SLS). Its a contraction for lauryl ether in its more formal name, sodium lauryl ether sulfate, or SLES. , Lets get technical. The CMC of SLS is roughly 8.1 mol m-3 at 25C. Gleason. Sodium lauryl sulfate is used in shampoos and cleansers. Surfactants enable the surface area of contact between the droplet and the substrate to be larger, and thus increase wetting of the substrate [4]. Sodium Lauryl Sulfate (SLS) is an anionic surfactant naturally derived from coconut and/or palm kernel oil. Its essentially a synthetic soap. The head group must be sufficiently soluble in water to be classed as a surfactant [2,3]. Actually the product is mixed, the "n" subscript in his formula giving only the AVERAGE number of ethyl ether groups per molecule, an. Answer (1 of 4): The "eth" indicates that the lauryl alcohol has been ethoxylated before being sulfonated, resulting in the structure the previous answerer posted. [1] The related surfactant sodium lauryl sulfate (also known as sodium dodecyl sulfate or SDS) is produced similarly, but without the ethoxylation step. It is derived from palm kernel oil or coconut oil. Formulas that contain SLS could irritate both a sensitive scalp and eyes, and formulas that contain SLES could be contaminated unless the company claims to have purified the chemical and ensures it is free from 1,4-dioxane. In the Ph.Eur, Sodium lauryl sulfate is described as a mixture of sodium alkyl sulfates and consists mainly of Sodium lauryl sulfate (chemical formula, CH3(CH 2)10CH 2 OSO 3 Na).

The chemical formula of Sodium Laureth sulfate is CH 3 (CH 2) 10 CH 2 (OCH 2 CH 2) n OSO3Na, and Its chemical structure is as seen in the picture: Most of the time, the commercial product presented by chemical providers is heterogeneous, meaning it differs in both length of the alkyl chain and the number of ethoxylates (C 2 H 4 O). For foam to exist there must be a substituent with the bulk of the liquid to lower surface tension. Technical Divisions Above a critical concentration SLS will form micelles in water. [5][6][7][8], Products containing SLES can be contaminated with (up to 300 ppm) of 1,4-dioxane, a by-product of SLES production.

Another use of SLS was documented in a study recently. Let ACS help you navigate your career journey with tools, personal coaching and networking. At the substrate a liquid droplet will form to have the least surface tension possible and thus the least surface area in contact with the substrate. PG-300995 is an anti-HIV agent, but is a poorly soluble drug in solution. experience redness, itching, or uncomfortableness), you may have developed an allergic reaction., Both SLS and SLES are commonly used in shampoo for their foaming properties that contribute to a robust lather and remove dirt and oils from the scalp. It's a widely used biochemical technique that separates proteins based on their molecular weight. Ether refers to one or more ethylene oxide groups placed between the sulfate and lauryl moieties. CAS Number: 151-21-3. Gosselin, H.C. Hodge, R.P. It is also known by the term sodium dodecyl sulfate. 420.54.
