Cocamidopropyl Hydroxysultaine

  • Amphoteric surfactants
  • CAS 70851-07-9
  • IUPAC: N-[3-(dimethylammonio)propyl]dodecanamide-2-hydroxypropane-1-sulfonate

Low irritation potential. No GHS health classifications in typical formulation concentrations. Milder than primary anionic surfactants — often used to reduce formulation irritancy.

Cocamidopropyl hydroxysultaine is a coconut-derived amphoteric (zwitterionic) surfactant used as a co-surfactant and foam booster in car shampoos and mild cleaning formulations. Its amphoteric nature means it's compatible with both anionic and cationic surfactants, and its presence in a formulation typically reduces overall skin and eye irritancy compared to anionic-only systems. Biodegrades aerobically. No significant aquatic toxicity classification. The PCHS class (sultaine-type) has an established safety record in personal care and automotive care applications.
