Quaternium-15 (Formaldehyde Releaser)
What is Quaternium-15 (Formaldehyde Releaser)?
Quaternium-15, also known as 1-(3-chloroallyl)-3,5,7-triaza-1-azoniaadamantane chloride, is a synthetic cationic quaternary ammonium salt designed for cosmetic formulations. It appears most often in hair conditioners, shampoos, and styling aids. In its antistatic capacity, the positively charged molecule binds to hair's negative surface charge, neutralizing static electricity to promote smoother, more manageable strands and reduce flyaways. As a preservative, it decomposes gradually to release formaldehyde, which disrupts microbial cell walls, inhibiting bacteria and fungi to safeguard product integrity during use and storage. This controlled release mechanism supports formulation stability in water-based cosmetics without immediate breakdown.
