Sodium Lauryl Sulfoacetate (SLSA) CAS 1847-58-1

SLSA is a distinct molecule, not a variant of SLS/SLES. It is a sulfoacetate — a larger, higher-molecular-weight anionic surfactant with a much lower skin-penetration profile, which translates into reduced irritation potential. Unlike sulfates, it is fully compatible with sulfate-free positioning, and it produces a denser, creamier lather.

  • Mild, Sulfate-Free Alternative to SLS/SLES A gentle anionic surfactant derived from coconut fatty alcohol. Its larger molecular size limits penetration into the skin barrier, making it markedly less irritating than SLS or SLES. The formulation of choice for sulfate-free shampoos, baby care, sensitive-skin cleansers and toothpaste.
  • Excellent Foaming with Dense, Creamy Lather Delivers abundant, stable and fine-textured foam even in hard water. It boosts both foam volume and foam quality in finished formulations, allowing brands to reduce the total surfactant load while maintaining consumer-perceived richness.
  • High Active Matter & Consistent Quality Supplied as a ≥ 95% active white powder, each batch standardized to a tight active-matter range. Consistent surface activity and color guarantee reproducible results from pilot trials to full-scale production.
  • Versatile Compatibility Across Applications Functions effectively as a primary or co-surfactant alongside amphoteric and non-ionic surfactants. Stable across a broad pH range and compatible with common preservatives and actives — suitable for shampoo, body wash, facial cleanser, toothpaste, bath bombs and cleansing bars.
  • Factory Direct Supply with Full Compliance Support Produced in an ISO-certified, GMP-compliant facility from coconut-derived feedstock. COSMOS/Ecocert and Halal documentation available on request. Every shipment is accompanied by a batch-specific CoA and MSDS.
