Sodium cetyl sulfate

Sodium Cetyl Sulfate (CAS 1120-01-0) is an anionic surfactant derived from cetyl alcohol, commercially known under trade names including Avitex SF and abbreviated as SHS. It carries no assigned E-code and is identified under EC number 214-292-4 with the molecular formula C16H34O4S.Na.

In personal care formulations, Sodium Cetyl Sulfate functions as an emulsifier by reducing interfacial tension between oil and water phases, stabilising creams and lotions at low use levels. In textile and leather processing, it acts as a wetting and dispersing agent, enabling uniform dye penetration and improving substrate uptake during finishing operations.

Sodium Cetyl Sulfate is supplied as a white powder and falls under HS code 34021100 for customs classification. It is subject to REACH registration requirements within the EU. Buyers should confirm grade specifications and available packaging formats directly with the supplier to ensure compliance with their application requirements.
