"Sodium...' means the element sodium, 'stearoyl' means stearic acid, 'hydrolyzed collagen' means collagen hydrolysates which have been rendered water-soluble by enzymatic processes. Collagen hydrolysates are obtained from animal connective tissue, especially bovine collagen. In Asia, collagen hydrolysates are often obtained from Pacific fish species (cod) or from chicken collagen.
Sodium hydrolyzed collagen is used in cosmetic formulations. The substance acts as an antistatic agent (reduces static electricity by neutralizing the electrical charge on the surface, e.g. of hair) and as a combability aid (reduces or prevents tangling of the hair due to changes or damage on the hair surface, thus improving combability).
