Sodium decyl sulfate

Sodium Decyl Sulfate (CAS 142-87-0) is an anionic surfactant derived from decyl alcohol, supplied as a white powder under trade names including Avirol 110, Pentrone DN, and Compound 132D. It carries no assigned E-code and is identified under EC 205-568-5 with the molecular formula C10H22O4S.Na.

In textile and leather processing, Sodium Decyl Sulfate functions as an emulsifier and wetting agent, reducing interfacial tension to ensure uniform dye penetration and consistent substrate treatment. In personal care formulations, its foaming and cleaning action derives from the sulfate head group binding to oils and particulates, enabling their removal during rinsing.

This material is supplied in powder form and falls under REACH regulation, requiring an up-to-date Safety Data Sheet for EU trade. Procurement teams should confirm grade specification and compliance documentation prior to ordering, as suitability varies across cosmetic, industrial cleaning, and paper-processing applications. Standard packaging formats apply per supplier specification.
