Description

Triethylene Glycol Monostearate is a non-ionic surfactant and emulsifier derived from the esterification of triethylene glycol with stearic acid. This compound is valued for its ability to modify viscosity, stabilize emulsions, and act as a dispersing agent in a wide range of formulations. It serves as a critical functional ingredient for manufacturers in the cosmetics, personal care, plastics, and food processing industries seeking reliable performance and material compatibility.

Application

• Cosmetics & Personal Care: Used as an opacifier, pearlescent agent, and viscosity modifier in creams, lotions, shampoos, and conditioners.
• Plastic & Polymer Industry: Functions as an internal and external lubricant and anti-static agent in PVC, polyolefins, and other polymer processing.
• Food Industry: Acts as an emulsifier and dispersant in certain food-grade applications, such as in whipped toppings and edible coatings.
• Textile Processing: Employed as a softening agent, lubricant, and anti-static finish for synthetic fibers and yarns.
• Industrial Lubricants: Serves as a component in synthetic lubricants and metalworking fluids.
• Agricultural Formulations: Used as an adjuvant in pesticide and herbicide formulations to improve spreading and adherence.
