It is widely used in daily necessities, cosmetics, polymer manufacturing industry and other fields. In daily necessities, it can be used with anionic, cationic and most amphoteric compounds to provide rich foam, good detergency and electrolyte stability, and is often used in the production of cosmetics and detergents, which is mild and does not hurt the skin. In emulsion polymerization, it can be used as emulsifier and stabilizer, can effectively control the size of the latex particle size, used in vinyl acetate, vinyl chloride, acrylic ester, styrene and styrene-propylene systems to meet the It is used in vinyl acetate, vinyl chloride, acrylate, styrene and styrene-propylene systems to meet polymer requirements for stability and scrub resistance. It mixes well with many natural and synthetic resins and can be used as a dispersant.
