Disodium 2-sulfolaurate

Disodium 2-sulfolaurate (CAS 38841-48-4) is an anionic surfactant derived from lauric acid, functioning as a cleansing, foaming, and emulsifying agent across personal care and industrial cleaning formulations.

It belongs to the alpha-sulfo fatty acid salt family, a class recognized for strong surface activity and compatibility with hard water conditions. In personal care, it is used as a primary or co-surfactant.

It is frequently found in shampoos, body washes, and facial cleansers where controlled foam and mildness are required. Home care and industrial cleaning products incorporate it to boost degreasing performance.

It also helps to stabilize emulsions in liquid detergent systems. Textile processing operations use it as a wetting and scouring agent to improve fiber penetration and soil removal during preparation stages.

In leather and paper manufacturing, it supports dispersion of processing aids and improves substrate uniformity during wet treatment steps. This versatility makes it a staple in various manufacturing sectors.

Disodium 2-sulfolaurate is typically supplied as a paste or aqueous solution, with active content commonly specified by the supplier. It is available in technical and industrial grades suited to cleaning.

Textile applications also benefit from these specific grades. Food-contact and personal care grades may be available where formulation compliance requires documented purity specifications for safety.
