How we scored it
Hydrolysate of natural chitosan; hydrolysis reagents (acid/enzyme) leave no mass.
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
Made by hydrolysing chitosan, itself derived from chitin in crustacean shells or fungal cell walls, using acid or enzymes. The hydrolysis agents leave no mass in the final product.
In plain English
A conditioning ingredient made by breaking down chitosan, a natural fibre from shellfish shells (or fungi), into smaller pieces. Used in hair and skin products to help them feel smoother.
CosIng definition: Hydrolyzed Chitosan is the hydrolysate of Chitosan derived by acid, enzyme or other method of hydrolysis
