VAXEN Sodium Cocoyl Isethionate (SCI) Powder 500g

Sodium cocoyl isethionate, usually shortened to SCI, is a cosmetic-grade anionic surfactant derived from coconut fatty acids. It produces a dense, creamy foam while being gentle on skin and hair, which has made it the primary surfactant in shampoo bar and syndet bar formulation. VAXEN SCI Powder is cosmetic grade, INCI Sodium Cocoyl Isethionate, CAS 61789-32-0.

SCI is typically the base surfactant in hot-process syndet formulation. Disperse the powder into the heated phase of your formulation, where it melts and blends evenly with the other ingredients, then combine with your chosen co-surfactants, oils and additives before moulding. It works well alongside SCS and cocamidopropyl betaine to build balanced cleansing systems for skin and hair.

SCI is derived from coconut fatty acids. Those fatty acids are converted into a mild anionic surfactant that is solid at room temperature, which is why SCI is so widely used in solid and waterless formats: shampoo bars, syndet bars, facial cleansing bars, powder cleansers and exfoliating scrubs.

SCI is classed as a mild anionic surfactant: it cleanses while producing a dense, creamy foam and is chosen by formulators specifically for formulations intended to be gentle on skin and hair. That mildness, combined with its solid format, is why it dominates syndet bar and facial cleansing bar recipes.

Yes. SCI blends well with SCS, cocamidopropyl betaine and other anionic or amphoteric surfactants, letting you balance foam, mildness and cleansing power in a bespoke blend. A common pairing is SCS for high-foam performance with SCI for creaminess and mildness. Full INCI, CAS 61789-32-0 and batch details are included on every VAXEN pack.
