Description

Ethane-1,2-Diylbis(Oxyethane-1,2-Diyl) Bispalmitate is a high-purity, synthetic diester compound derived from palmitic acid and a polyethylene glycol (PEG) backbone. This chemical serves as a versatile non-ionic surfactant and emollient, prized for its ability to enhance solubility, stability, and texture in complex formulations. It is a critical ingredient for manufacturers in the personal care, cosmetics, and pharmaceutical industries seeking reliable, high-performance raw materials for their products.

Application

• Cosmetic & Personal Care Formulations: Acts as a premium emollient, solubilizer, and texture enhancer in creams, lotions, sunscreens, and makeup products.
• Pharmaceutical Excipient: Used as a non-ionic surfactant and solubilizing agent in topical drug delivery systems, ointments, and creams.
• Industrial Lubricants & Release Agents: Functions as a biodegradable lubricant component and mold release agent in polymer processing.
• Plasticizer & Softener: Imparts flexibility and softness to polymer films and synthetic materials.
• Textile Processing: Employed as a softening agent and lubricant in fiber and fabric treatment.
• Agricultural Adjuvants: Used as a component in pesticide and herbicide formulations to improve spreading and adherence.
