About

A gentle amphoteric surfactant derived from capryl and capramidopropyl betaine, providing rich foam and excellent skin compatibility in cleansers.

This hydroxysultaine is related to the babassu derivative (34512) but uses a shorter capryl/capra (C8-C10) fatty acid chain profile, which generally reduces residual allergenicity. Hydroxysultaines are amphoteric surfactants that remain effective across a broad pH range and are noted for low irritation potential in patch testing. Not restricted in EU Annexes II or III. Readily biodegradable.

Skin benefits

  • Ultra-mild cleansing for facial and body products
  • Excellent foaming even in hard water
  • Good compatibility with other surfactants

Known concerns

  • Amide bond may hydrolyse under extreme pH conditions
  • Low irritation but eye contact should be minimised
