Quaternium-19 Consensus Reports
Quaternium-19 Specification
Quaternium-19, with the CAS NO. 81859-24-7, is a white granular powder with a characteristic amine odor. In cosmetics and personal care products, it is used mainly in the formulation of hair care products, lotions and makeup. When used in hair care products, Polyquaternium-10 can reduce static electricity.Quaternium-19 is also known as Polyquaternium-10. It adsorbs well to proteinaceous surfaces, such as the proteins in hair. It is in the chemical class known as quaternary ammonium compounds.
The toxicity data is as follows:
