Function:
1. It has good lubricity.
2. It has emulsification function
3. When 12-hydroxystearic acid is added to some systems, it can increase the viscosity of the system
4. The hydroxyl group in the molecule is an active functional group that can participate in a variety of chemical reactions.
Application:
1.12-hydroxystearic acid is used in the manufacture of various industrial greases, such as greases for automotive hub bearings, industrial machinery bearings, etc.
2. In the plastics and rubber industry, it can be used as a plasticizer and release agent.
3.12-hydroxystearic acid can improve the performance of coatings and inks. For example, as emulsifiers, thickeners and leveling agents.
4. In cosmetics lotions and creams, 12-hydroxystearic acid mainly plays the role of emulsification and thickening
5. In shampoos and body washes, it acts as a surfactant to help clean skin and hair.
6.12-hydroxystearic acid can be used as emulsifier and stabilizer in the food industry. For example, the production of margarine, ice cream and other foods, it can also play a role in preventing frost in chocolate and other foods.
