Description

Monooxyethylene Trimethylolpropane Tristearate is a specialized non-ionic surfactant and emulsifier derived from trimethylolpropane. This compound is valued for its excellent lubricity, emulsifying properties, and thermal stability, making it a versatile functional additive. It is primarily used in industrial formulations requiring high-performance surface modification and stabilization, such as in synthetic lubricants, polymer processing, and cosmetic emulsions.

Application

• As a high-efficiency internal and external lubricant in PVC processing and other polymer systems.
• As an emulsifier and stabilizer in the production of cosmetics and personal care products, including creams and lotions.
• As a key component in formulating synthetic metalworking fluids and industrial lubricants.
• As a processing aid and release agent in the plastics and rubber industries.
• As a textile auxiliary for fiber lubrication and softening.
• As a co-emulsifier in specialty agricultural chemical formulations.
