The Uses of Quaternium-15

1-(3-Chloroallyl)-3,5,7-triaza-lazonia- adamantane chloride is a formaldehyde-releasing preservative in hand creams, lotions, face creams, shampoos, latex paints, topical medicaments, polishes, metal-working fluids, adhesives, inks, etc.; quatemium-15.

The Uses of Quaternium-15

1-(cis-3-Chloroallyl)-3,5,7-triaza-1-azoniaadamantane chloride may be used as a formaldehyde releaser to investigate the influence of formaldehyde in dermatitis patients with or without contact allergy to formaldehyde through baseline patch test series.

Biochem/physiol Actions

1-(cis-3-Chloroallyl)-3,5,7-triaza-1-azoniaadamantane chloride, also known as quaternium-15, is used as a preservative in some cosmetics and other industrial products. It releases formaldehyde therefore, repeated use products containing quaternium-15 may cause contact dermatitis.
