Disodium Laureth Sulfosuccinate is a surfactant. It is a disodium salt of ethoxylated lauryl alcohol bound to sulfosuccinic acid. Disodium Laureth Sulfosuccinate is primarily used in cleansing products, including bubble baths, bath soaps and detergents, shampoos and shaving cream.
In cosmetics and personal care products, Disodium Laureth Sulfosuccinate functions as a surfactant
Disodium Laureth Sulfosuccinate is an anionic surfactant. This means that this ingredient has a negative charge. The negative charge is associated with the sulfosuccinate portion of the compound. Surfactants function by reducing the surface tension of water which makes it easier to wash dirt from the skin and hair.
The Food and Drug Administration (FDA) includes Disodium Laureth Sulfosuccinate on its list of indirect food additives that may be used as an emulsifier and/or surface active agent in articles in contact with food. The safety of Disodium Laureth Sulfosuccinate has been assessed by the Cosmetic Ingredient Review (CIR) Expert Panel. The CIR Expert Panel evaluated the scientific data and concluded that this ingredient was safe for use in cosmetics and personal care products in the present practices of use and concentration when formulated to be non-irritating.
CIR Safety Review:
Based on its high molecular weight and negative charge, the CIR Expert Panel concluded that it not likely that Disodium Laureth Sulfosuccinate as used in personal care products would penetrate the skin. The CIR Expert Panel reviewed data that showed no systemic toxicity following oral exposure. Disodium Laureth Sulfosuccinate was not genotoxic and related compounds were not reproductive or developmental toxicants. Disodium Laureth Sulfosuccinate was not a sensitizer. Depending on the concentration and formulation, Disodium Laureth Sulfosuccinate can be irritating to the skin and eyes. Therefore, the CIR Expert Panel concluded that Disodium Laureth Sulfosuccinate was safe in the present practices of use and concentration when formulated to be non-irritating. Trace amounts of 1,4-dioxane, a by-product of ethoxylation may be found Disodium Laureth Sulfosuccinate. The potential presence of 1,4-dioxane is well known and can be controlled through purification steps to minimize it from the ingredient before blending into cosmetic formulations.

Disodium Laureth Sulfosuccinate has a lauryl alcohol group that is ethoxylated. The lauryl alcohol group in Disodium Laureth Sulfosuccinate is bound to a polyethylene glycol chain that contains an average of 1 to 4 ethoxy units. The ethoxylate of lauryl alcohol serves to increase the water solubility of the compound.
