Sodium myristyl sulfate

Sodium myristyl sulfate (CAS 1191-50-0), also known as sodium tetradecyl sulfate, is an anionic surfactant derived from myristic acid. It delivers strong foaming, emulsification, and cleansing performance across pharmaceutical and personal care applications.

In personal care formulations, it functions as a primary or co-surfactant in shampoos, facial cleansers, and body washes where dense, stable foam is a key performance requirement.

Pharmaceutical manufacturers use it as an emulsifying and dispersing agent in topical creams, ointments, and gel formulations. It also appears in specialty cleansing systems where controlled degreasing is needed.

This ingredient is utilized without the harshness associated with shorter-chain sulfates. In cosmetic emulsion development, its C14 chain length positions it between lauryl and cetyl sulfates.

This specific molecular structure gives formulators a mid-range option for adjusting foam texture and skin feel. Sodium myristyl sulfate is typically supplied as a white to off-white powder or paste.

The physical form depends on active content. Standard grades include cosmetic-grade and pharmaceutical-grade material, with specifications aligned to industry purity requirements for topical and rinse-off applications.

Buyers should confirm active matter content and sodium sulfate levels, as these vary between suppliers. These factors directly affect formulation performance and stability in the final product.
