How we scored it
Chitosan (chitin-derived) + lactic acid (fermentation) salt, both natural fragments → 2/2 natural, 1.0.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.
Where it comes from
Chitosan from deacetylated crustacean-shell or fungal chitin, salted with fermentation-derived lactic acid from sugar feedstocks.
In plain English
A film-forming, hair-fixing polymer made from chitosan, from crustacean shells or fungi, combined with lactic acid, a fermentation-derived acid. Used in hairsprays and styling products.
CosIng definition: Chitosan, 2-hydroxypropanoate salt
