Poly(ethylene glycol) distearate is a non-ionic surfactant widely used as an emulsifier and stabilizer in cosmetics and personal care products. It facilitates the blending of oil and water-based ingredients, resulting in smooth and consistent textures for creams, lotions, shampoos, and makeup.

In the pharmaceutical industry, it functions as an emulsifying agent in topical formulations such as creams and ointments, aiding drug absorption through the skin, and as a lubricant in tablet and capsule production to improve manufacturing processes.

Additionally, it is employed in the textile industry as a lubricant and softening agent during manufacturing. Its biocompatibility and versatility make it valuable across these sectors.
