Polyurethane-24
A cosmetic ingredient used as hair conditioning, hair fixing in skincare, haircare, and personal-care products sold in the European Union.
What is it?
Polyurethane-24 is a complex polymer prepared via the following multi-step synthesis. First, isophorone diisocyanate (IPDI) is reacted with three different polyols: Poly(1,4-Butanediol)-30, 1,4-Butanediol, and dimethylol butanoic acid. This pre-polymer is then reacted with a reagent formed by the reaction between Aminpropyl Triethoxysilane and lauryl acrylate. The resulting polymer is subsequently chain extended by reaction with isophorone diamine in aqueous solution to produce Polyurethane-24
What does it do?
Polyurethane-24 is listed in the EU cosmetic ingredient inventory with the following declared functions:
-
Hair conditioning
improves the appearance, feel, and manageability of hair
-
Hair fixing
holds hair in a desired style, typically through a flexible film coating each strand
EU regulatory status
Polyurethane-24 is allowed for use in cosmetic products in the European Union under Regulation 1223/2009. It is not subject to a specific Annex restriction at the time of writing.
