How we scored it
Amino acids/peptides from acid, alkaline or enzymatic hydrolysis of soy protein; hydrolysis reagents leave no mass; hydrolysed protein = 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
Produced by acid, alkaline, or enzymatic hydrolysis of soybean protein into amino acids and peptides. No petrochemical route is used; only the hydrolysis catalyst, which contributes no product mass, varies.
In plain English
A blend of amino acids and small peptides made by breaking down soy protein, used to condition hair and skin and hold in moisture. It comes entirely from soybeans.
CosIng definition: Protein hydrolyzates, soya. Substance obtained by acidic, alkaline, or enzymatic hydrolysis of soya composed primarily of amino acids, peptides, and proteins. It may contain impurities consisting chiefly of carbohydrates and lipids along with smaller quantities of miscellaneous organic substances of biological origin
