Description

Polyoxy(Methyl-1,2-Ethanediyl), .Alpha.-(1-Oxooctadecyl)-.Omega.-(1-Oxooctadecyl)Oxy- is a high-purity, non-ionic surfactant and emulsifier belonging to the class of polyethylene glycol (PEG) distearates. This compound is valued for its excellent stabilizing and conditioning properties, making it a critical component in formulations requiring consistent texture and performance. It is primarily sought after by manufacturers in the personal care, cosmetics, and pharmaceutical industries for its ability to create stable emulsions and enhance product feel.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary emulsifier and opacifier in creams, lotions, and conditioners to provide a rich, stable texture.
• Pharmaceutical Topicals: Used as an excipient in ointments, creams, and topical drug delivery systems for its emulsifying and stabilizing properties.
• Industrial Lubricants & Release Agents: Serves as a component in synthetic lubricants and mold release agents due to its film-forming ability.
• Textile & Fiber Processing: Employed as a softening agent and lubricant in fiber production and textile finishing.
• Agricultural Adjuvants: Functions as a surfactant in pesticide and herbicide formulations to improve spreading and adherence.
• Polymer & Plastic Additives: Used as an internal or external lubricant and anti-static agent in plastic processing.
