Science
Mechanism of Action
This ingredient, a quaternary ammonium salt modified with hydrolyzed silk amino acids, possesses a cationic character that enables it to effectively adsorb to skin surfaces. Upon application, it forms a protective film, thereby enhancing the skin's defense against environmental damage and bolstering its natural moisture barrier. The embedded silk amino acids, as essential protein building blocks, actively bind and retain moisture, promoting sustained hydration, improved skin texture, and supporting natural regeneration.

Safety Profile
While the Cosmetic Ingredient Review (CIR) Expert Panel has not specifically reviewed COCODIMONIUM HYDROXYPROPYL SILK AMINO ACIDS, they have assessed α-amino acids as safe for cosmetic use and found silk protein ingredients generally to be mild skin irritants at most, without sensitization potential. No specific maximum concentration for skin applications of this ingredient has been explicitly established by regulatory bodies like CIR, SCCS, or FDA. It is not currently listed on EWG's Skin Deep Restricted or Unacceptable Lists, and GHS hazard information from The Good Scents Company reports 'None found'.
