from Wikipedia, the free encyclopedia

Hydroxypropylguarhydroxypropyltrimethylammoniumchlorid ( INCI designation HYDROXYPROPYL, guar hydroxypropyltrimonium chloride ) is a quaternary ammonium salt , which in cosmetic is used products. The substance is one of the polymers . The associated CAS number is 71329-50-5.

Manufacturing
