ALUMINUM CAPRYLOYL HYDROLYZED COLLAGEN.

Questionable CAS 165800-56-6 / ANTISTATIC, HAIR CONDITIONING, SKIN CONDITIONING

This unique ingredient combines hydrolyzed collagen with a capryloyl group and aluminum salt, functioning as a multifaceted skin and hair conditioning agent with antiperspirant properties.

Summary

antistatic skin conditioning hair conditioning antiperspirant

Science

Mechanism of Action

The capryloyl modification enhances the lipophilic nature of hydrolyzed collagen, improving skin and hair adherence. Its aluminum salt component provides astringent and antiperspirant effects by temporarily forming plugs in sweat ducts, also neutralizing surface electrical charges.

Stability

Optimal stability is observed within a slightly acidic to near-neutral pH range (4.5–7.0). Extreme pH values below 4.5 or above 8.5 can significantly increase aluminum component solubility, potentially destabilizing the complex.

Conflicts

  • Strong chelating agents (e.g., EDTA)
  • High concentrations of electrolytes
  • Anionic surfactants
