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.
Sodium laurylsulfate tested on Uronema parduczi, a protozoan, was found to have the lowest effect value with the 20 h-EC5 being 0.75 milligrams per litre (2.7 × 10 −8 lb/cu in). Chronic exposure tests with C 12 to C 18 with the invertebrate Ceriodaphnia dubia found the highest toxicity is with C 14 ( NOEC was 0.045 mg/L).
A foaming agent is a material such as a surfactant or a blowing agent that facilitates the formation of foam.A surfactant, when present in small amounts, reduces surface tension of a liquid (reduces the work needed to create the foam) or increases its colloidal stability by inhibiting coalescence of bubbles.

Sodium alketh sulfate, known prior to being renamed in 2021 as sodium pareth sulfate, [1] and 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).
Sodium dodecyl sulfate, appearing as its synonym sodium lauryl sulfate (SLS), is considered a generally recognized as safe (GRAS) ingredient for food use according to the USFDA (21 CFR 172.822). [7] It is used as an emulsifying agent and whipping aid. [ 8 ]
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]
