Description

Sodium 9,10-Dihydroxystearate is the sodium salt derivative of 9,10-dihydroxystearic acid, a functionalized fatty acid. This compound is valued for its surfactant and emulsifying properties, derived from its unique dihydroxylated stearate structure. It is primarily utilized in industrial applications requiring specialized anionic surfactants, such as in the formulation of lubricants, metalworking fluids, and specialty soaps. The product is supplied under the identifier CAS NO 20731-55-9.

Application

• As a specialized anionic surfactant and emulsifier in industrial lubricant formulations.
• Key component in the production of metalworking fluids and coolants.
• Used in the synthesis of high-value specialty soaps and cleaning compounds.
• Intermediate for further chemical synthesis in the production of polymer additives.
• Potential emulsifying agent in textile processing and fiber lubricants.
• Functional additive in corrosion inhibitor packages for various industrial systems.
