Use

1. Rubber industry

Stearic acid plays an important role in the synthesis and processing of rubber. Stearic acid is a vulcanization active agent widely used in natural rubber, synthetic rubber and latex, and can also be used as a plasticizer and softener. In the process of producing synthetic rubber, stearic acid must be added as an emulsifier. In the production of foam rubber, stearic acid can be used as a foaming agent, and stearic acid can also be used as a release agent for rubber products.

2. Cosmetics industry

Stearic acid is used in two types of skin care products, vanishing cream and cold cream, to emulsify it into a stable and white cream. Stearic acid is also the main raw material for making almond honey and milk. Stearic acid soap esters are more widely used in the cosmetics industry.
