Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-Hydro-.Omega.-(1-Oxooctadecyl)Oxy-, Ether With 2,2-Bis(Hydroxymethyl)-1,3-Propanediol (4:1) is a specialized, non-ionic surfactant and emulsifier derived from a polyethoxylated stearyl alcohol and pentaerythritol structure. This chemical is valued for its ability to provide excellent stability, lubrication, and conditioning effects in complex formulations. It is primarily sought by manufacturers in the personal care, cosmetics, and specialty chemical industries for creating high-performance products.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary emulsifier and stabilizer in creams, lotions, and ointments, providing a smooth texture and enhanced skin feel.
• Hair Care Products: Used in conditioners and styling aids for its lubricating and anti-static properties, improving hair manageability and shine.
• Skin Care Emulsions: Effective in stabilizing oil-in-water (O/W) emulsions for moisturizers, serums, and sunscreens.
• Pharmaceutical Topicals: Serves as a non-irritating emulsifying base for medicated creams and dermatological preparations.
• Industrial Lubricants & Release Agents: Functions as an additive in synthetic lubricants and mold release agents due to its surfactant properties.
• Textile & Fiber Processing: Employed as a softening agent and lubricant in fiber treatments and fabric finishes.
