Sodium cetearyl sulfate

Sodium cetearyl sulfate (CAS 59186-41-3) is an anionic surfactant derived from a blend of cetyl and stearyl alcohols, supplied as a sodium salt of the mixed sulfate esters. It functions as an emulsifier and cleansing agent across personal care, pharmaceutical, and industrial formulations.

In cosmetic emulsions, such as creams, lotions, and hair conditioners, it stabilizes oil-in-water systems and contributes to a smooth, spreadable texture. Formulators target this ingredient for both leave-on and rinse-off products to ensure consistency.

Pharmaceutical manufacturers use it as an emulsifying excipient in topical preparations such as creams and ointments. In these applications, consistent droplet size and formulation stability are critical to the overall performance of the medicinal product.

In shampoos and body washes, it delivers foam generation and surface wetting alongside primary surfactants. This synergy improves overall cleansing efficiency and enhances the sensory experience for the end user during application.

Industrial cleaning formulations also incorporate this compound for its degreasing and wetting performance on hard surfaces. Its chemical properties allow for effective soil removal in various commercial and technical environments.

Sodium cetearyl sulfate is commercially available as a white to off-white powder or paste. Standard supply grades include cosmetic or personal care grade and pharmaceutical grade for specialized manufacturing requirements.

The pharmaceutical grade typically meets BP or Ph.Eur. specifications to ensure high purity and safety. Bulk quantities are commonly offered in bags or drums, with technical-grade material available for non-cosmetic industrial applications.
