cis-1-(3-Chloroallyl)-3,5,7-triaza-1-azoniaadamantane chloride
Quaternium-15 is a quaternary ammonium salt used as a preservative in many cosmetics and industrial substances. It acts as a formaldehyde releaser. It can cause contact dermatitis in sensitive individuals. It's toxicity is also due to it's ability to react and release formaldehyde and nitrosamines, both of which are believed to be carcinogenic.
