Alkyl sulfates if ingested are well-absorbed and are metabolized into a C 3, C 4 or C 5 sulfate and an additional metabolite. The highest irritant of the alkyl sulfates is sodium laurylsulfate, with the threshold before irritation at a concentration of 20%. Surfactants in consumer products are typically mixed, reducing likelihood of irritation.
Sodium laureth sulfate (SLES), an accepted contraction of sodium lauryl ether sulfate, also called sodium alkylethersulfate, is an anionic detergent and surfactant found in many personal care products (soaps, shampoos, toothpaste, etc.) and for industrial uses. SLES is an inexpensive and very effective foaming agent. [1]
Prominent alkyl sulfates include ammonium lauryl sulfate, sodium lauryl sulfate (sodium dodecyl sulfate, SLS, or SDS), and the related alkyl-ether sulfates sodium laureth sulfate (sodium lauryl ether sulfate or SLES), and sodium myreth sulfate. Others include: Alkylbenzene sulfonates; Docusate (dioctyl sodium sulfosuccinate ...
Along with sodium laureth sulfate, they are one of the oldest and most widely used synthetic detergents and may be found in numerous personal-care products (soaps, shampoos, toothpaste etc.) and household-care products (laundry detergent, dishwashing liquid, spray cleaner etc.). [1]
Sodium dodecyl sulfate (SDS) or sodium lauryl sulfate (SLS), sometimes written sodium laurilsulfate, is an organic compound with the formula CH 3 (CH 2) 11 OSO 3 Na and structure H 3 C−(CH 2) 11 −O−S(=O) 2 −O − Na +. It is an anionic surfactant used in many cleaning and hygiene products. This compound is the sodium salt of the 12 ...
Hydrophobic coagulation occurs when a positively charged solution is added with a sodium alkyl sulfate. The coagulation value is smaller when the alkyl chain length of the coagulator is longer. Hydrophobic coagulation occurs when a negatively charged solution contains a cationic surfactant.
Sodium pareth sulfate, recently renamed to sodium alketh sulfate [1], and known also as sodium polyoxyethylene alkyl ether sulfate, is a surfactant found in some detergent products such as hand or body washes, but not as commonly as other chemicals such as sodium laureth sulfate (SLES). It is the sodium salt of a sulfated polyethylene glycol ether.
R= Alkyl, M= Na +, n = 1 or 2. α-Olefin sulfonates (also: alpha-olefin sulfonates or AOS) are a group of anionic surfactants, which are used as detergents. [1] The compounds contain a - mostly linear, primary - alkyl R and a monovalent cation M, preferably sodium. [2]
