Sodium myristyl sulfate

Sodium myristyl sulfate (CAS 1191-50-0), also known as sodium tetradecyl sulfate, is an anionic surfactant derived from myristic acid.

Where is Sodium myristyl sulfate used?

• Personal care: primary or co-surfactant in shampoos, facial cleansers and body washes for dense, stable foam
• Pharmaceuticals: emulsifying and dispersing agent in topical creams, ointments and gels
• Specialty cleansing systems: controlled degreasing
• Its C14 chain length positions it between lauryl and cetyl sulfates in cosmetic emulsion development.

Good to know: Utilized without the harshness associated with shorter-chain sulfates. Buyers should confirm active matter content and sodium sulfate levels, as these vary between suppliers and affect formulation performance and stability.

Commercial specifications

• Active matter content and sodium sulfate levels vary between suppliers; verify before purchase
• Physical form depends on active content
• Cosmetic-grade and pharmaceutical-grade material with specifications aligned to industry purity requirements for topical and rinse-off applications
