Sodium stearate is a white, oily powder with a slippery and fatty smell. Soluble in hot water or hot alcohol. The aqueous solution is alkaline due to hydrolysis, and the alcohol solution is neutral. It is prepared by the interaction of octadecanoic acid and sodium hydroxide. It is used in the manufacture of toothpaste and is also used as a water repellent and a plastic stabilizer.
Main uses of sodium stearate: thickening agent; Emulsifier; Dispersant; Adhesive; Corrosion inhibitor
1, detergent: used to control the foam in the rinse process.
2. Emulsifiers or dispersants: Emulsifiers and antioxidants for polymers are medium.
3. Corrosion inhibitors: Cluster packaging film to make it have protective properties.
4. Makeup: shaving gel, transparent viscose, etc.
5. Adhesive: used as natural glue and then paste paper.
Sodium stearate can be used as polyvinyl chloride heat stabilizer, as well as cosmetic flour, skin ointment and pharmaceutical tablet raw materials (excipients, lubricants); Used to make wood powder lubricated bright and transparent; Paint industry for transparent polishing agent. Metal soaps used as polyvinyl chloride stabilizers are mainly advanced fatty acid salts of cadmium, barium, calcium, zinc and magnesium. The base is stearic acid and lauric acid salts. The performance of metal soap stabilizer varies with the type of metal and the acid group, and the general rule is as follows: Heat resistance: cadmium, zinc soap has good initial heat resistance; Barium, calcium, magnesium, strontium soap has good long-term heat resistance, and lead soap is in the middle. Weather resistance: cadmium, zinc, lead, barium, tin soap is better. Processability: The lubricity of lead and cadmium soap is good, but the acid group also has a great influence on the lubricity. Widely used in food, medicine, coatings, plastics, rubber, textile and so on.
