How we scored it
Where it comes from
Collagen from bovine or porcine hide or fish skin is hydrolysed and then reacted with a quaternary ammonium reagent, usually a glycidyl- or chlorohydroxypropyl-ammonium compound. The exact quaternising agent and degree of substitution are not specified, so the value is an estimate.
In plain English
Collagen protein broken into small peptides and chemically given a positive charge so it clings to hair and skin. Used to condition and reduce static in shampoos and conditioners. The protein is animal-derived; the charged group is added synthetically.
