Description

Polypropyleneglycolazelate (End-Capped with stearic acid) is a specialized synthetic ester polymer, functioning as a high-performance emollient and lubricant. This compound is valued for its excellent skin compatibility, low irritation potential, and ability to form stable, non-greasy films. It is primarily sought after by manufacturers in the cosmetics, personal care, and pharmaceutical industries for formulating premium skin creams, lotions, and topical ointments.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary emollient and skin-conditioning agent in creams, lotions, sunscreens, and makeup products.
• Pharmaceutical Topicals: Used as a base or excipient in ointments, gels, and medicated creams for enhanced drug delivery and patient comfort.
• Lubricants & Release Agents: Serves as a non-toxic lubricant in machinery for food processing or in mold release applications for plastics and rubber.
• Plasticizer: Imparts flexibility and improves low-temperature performance in polymer resins and elastomers.
• Hair Care Products: Provides conditioning and shine in shampoos, conditioners, and hair styling products.
• Industrial Lubricants & Greases: Employed in formulating biodegradable and environmentally compatible lubricating greases.
