Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-Hydro-.Omega.-Hydroxy-, Ether With 1,2,3-Propanetriol Monooctadecanoate (2:1) is a non-ionic surfactant and emulsifier derived from glycerol monostearate and polyethylene glycol. This compound matters for its ability to effectively stabilize oil-in-water emulsions and modify the texture and consistency of formulations. It is primarily needed by manufacturers in the cosmetics, personal care, and pharmaceutical industries for creating creams, lotions, and ointments with a smooth, non-greasy feel.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary emulsifier and stabilizer in creams, lotions, and moisturizers.
• Pharmaceutical Topicals: Used in ointments, dermatological creams, and medicated pastes for consistent drug delivery and texture.
• Food Industry (where grade compliant): Functions as an emulsifier and texture modifier in certain food products and food packaging coatings.
• Industrial Applications: Serves as an emulsifier, dispersant, or lubricant in textile processing, paper coatings, and polymer additives.
• Agricultural Adjuvants: Used in pesticide and herbicide formulations to enhance spreading and adherence on plant surfaces.
