Description

Pentaerythritol Distearate CAS NO 13081-97-5 is a high-purity, synthetic ester derived from pentaerythritol and stearic acid, functioning as a versatile non-ionic surfactant and lubricant. Its value lies in providing excellent emulsifying, softening, and anti-static properties, which are critical for enhancing product performance and process stability. This chemical is essential for manufacturers in the plastics, personal care, and textile industries seeking reliable auxiliary agents for polymer processing, fiber treatment, and cosmetic formulations.

Application

• Acts as an internal and external lubricant and mold release agent in PVC, polyolefin, and engineering plastic production.
• Serves as a softening agent and spin finish in synthetic fiber and textile manufacturing.
• Functions as an emulsifier and opacifier in cosmetic and personal care products like creams and lotions.
• Used as a viscosity modifier and processing aid in paint, ink, and coating formulations.
• Employed as an anti-static agent and dispersant in various industrial chemical processes.
• Acts as a component in candle wax blends to modify crystallization and burning properties.
