About
Conditioning agent derived from hydrolyzed jojoba protein that helps protect hair
Laurdimonium hydroxypropyl hydrolyzed jojoba protein is produced by hydrolyzing jojoba protein and then quaternizing with lauryl dimethyl amine and hydroxypropyl substituents. This cationic protein derivative provides substantive conditioning benefits to skin and hair through electrostatic attraction to negatively charged surfaces. EU cosmetics regulation lists this ingredient without specific restrictions. The quaternary ammonium structure (like benzalkonium chloride) is well-established in cosmetics, though skin compatibility should be assessed in finished formulations.
Skin benefits
- Provides substantive skin-conditioning benefits through cationic protein deposition
- Hydrolyzed jojoba protein delivers amino acids and peptides to skin surface
- Improves skin feel and smoothness after application
Known concerns
- Quaternary ammonium compounds may cause irritation in敏感皮肤 (sensitive skin) individuals
- Cationic nature may cause incompatibility with anionic (sulphate) surfactants in formulations
