Mainly used for synthesizing detergents as additives, soap enhancers, and preventing soap oil precipitation and frosting. It has a strong emulsifying effect on lubricating oils and fats, and can be used to adjust the pH value of buffer soap solutions. It is also used as a dispersant in industrial water softeners, leather pretanning agents, dyeing aids, paints, kaolin, magnesium oxide, calcium carbonate and other industrial suspensions. It is also used as a dispersant in drilling and mud, and as an oil repellent in the paper industry.
