C12-14 HYDROXYALKYL HYDROXYETHYL BETA-ALANINE.

Valuable CAS 70521-70-9 / 70521-71-0 / CLEANSING, HAIR CONDITIONING, SURFACTANT - CLEANSING, SURFACTANT - FOAM BOOSTING

An amphoteric amino acid-based surfactant that combines gentle cleansing with conditioning properties through its unique zwitterionic structure. The C12-14 alkyl chain provides effective lipophilic cleansing while the beta-alanine headgroup delivers pH-responsive conditioning benefits. This dual-function ingredient excels as both a primary mild cleanser and foam-boosting secondary surfactant across all skin types.

Summary

cleansing hair conditioning surfactant foam boosting

Science

Mechanism of Action

Functions as a pH-responsive amphoteric surfactant where the beta-alanine nitrogen becomes protonated at lower pH levels, creating cationic charge that binds to negatively charged keratin for conditioning effects. At neutral pH, maintains zwitterionic character for gentle cleansing while the C12-14 alkyl chain provides lipophilic properties for effective sebum removal and foam stabilization.

Key findings

  1. 01 Patent studies demonstrate effective secondary surfactant properties at 0.1-1.0% in leave-on formulations, improving skin softness while reducing primary surfactant irritation
  2. 02 Technical formulations at 1.0-5.0% in rinse-off products show superior foam volume and density with lower irritancy compared to traditional betaines
