Sodium laureth carboxylate

Sodium laureth carboxylate (CAS 33939-64-9) is an ether carboxylate surfactant derived from ethoxylated lauryl alcohol.

Where is Sodium laureth carboxylate used?

• Personal care: cleansing, foaming and emulsification
• Shampoos and body washes: primary or co-surfactant generating stable foam compatible with skin and hair proteins
• Facial cleansers and micellar formulations: emulsifies sebum and cosmetic residues without the harshness of conventional sulfate surfactants
• Conditioning rinse-off products: controlled foam and low irritation potential
• Liquid hand soaps and baby care products rely on it for degreasing with a gentler cleansing profile.

Good to know: Mildness profiles suit sensitive-skin lines and frequent use on delicate skin. Cosmetic-grade material meets purity requirements for personal care finished goods.
