Description
Sodium Laureth Carboxylate (CAS 33939-64-9) is an ethoxylated fatty acid surfactant sold under trade names including Akypo-Soft 45NV, Akypo-Soft 100NV, Surfine WLL-A, and Sandopan 6624. It carries no assigned E-code and is also referenced as Sodium Laureth-5 Carboxylate in INCI nomenclature.
In personal care formulations, it functions as a mild anionic surfactant that tolerates high electrolyte concentrations, making it suitable for conditioning shampoos and sulfate-free cleansers where foam stability and low irritation potential are required. It also acts as an emulsifier in rinse-off skin care products, stabilising oil-in-water systems through its ethylene oxide chain.
Sodium Laureth Carboxylate is supplied in liquid form at varying ethoxylation degrees, with Akypo-Soft 45NV and 100NV representing distinct EO chain lengths for formulation flexibility. The substance falls under REACH registration obligations within the EU. Procurement teams should confirm supplier REACH compliance documentation and SDS before ordering.
