About
A conditioning complex of hydrolyzed soy protein with PEG-7 modified dimethicone, providing film-forming and moisturizing benefits for skin and hair.
Hydrolyzed Soy Protein/Dimethicone PEG-7 Acetate is formed by reacting hydrolyzed soy protein with the acetic acid ester of PEG-7 Dimethicone, combining protein conditioning with silicone smoothing properties. Soy allergy is less common than wheat allergy in the general population, and the hydrolysis process further reduces allergenic potential. The ingredient is not restricted under EU Regulation 1223/2009 Annexes II or III. The PEG-7 Dimethicone component is well-established in cosmetic formulations and considered safe at use concentrations.
