About

Derived from hydrolyzed silk protein, helps smooth and condition hair.

Steardimonium Hydroxypropyl Hydrolyzed Silk is a quaternary ammonium-modified hydrolyzed silk protein used as a high-end conditioning ingredient in cosmetic formulations. Not restricted under EU Regulation 1223/2009, silk protein derivatives are prized for their smooth texture and excellent film-forming properties that impart a luxurious sensory experience. Silk proteins have low allergenic potential compared to animal-derived proteins and are considered premium conditioning agents in skin and hair care.
