Polyethylene glycol-30 dipolyhydroxystearate

Polyethylene glycol-30 dipolyhydroxystearate (CAS 70142-34-6 ), also known commercially as Polyethylene glycol-15-hydroxystearate, is a polymeric emulsifier derived from hydroxystearic acid and polyethylene glycol. It stabilizes oil-in-water and water-in-oil emulsions across personal care, pharmaceutical, and industrial formulations where conventional emulsifiers fall short. In cosmetic formulations, it enables stable emulsions in sunscreens and lotions. This is particularly useful where high oil-phase loads or UV filters are difficult to suspend. Pharmaceutical manufacturers use it to solubilize and disperse poorly water-soluble active ingredients in topical and oral dosage forms. In textile processing, it functions as a wetting and dispersing agent that improves dye penetration and surface uniformity on synthetic fibers. Food-contact and industrial applications leverage its emulsifying performance. The material maintains stability in systems requiring compatibility across a broad range of pH and temperature conditions. Polyethylene glycol-30 dipolyhydroxystearate is typically supplied as a waxy solid or paste. Handling characteristics vary by temperature, and it is available in cosmetic-grade and pharmaceutical-grade specifications. The latter often aligns to excipient standards relevant to topical and oral formulations. Bulk supply is standard in drum or container quantities, with smaller packaging available for formulation development. This versatile emulsifier ensures long-term stability and performance in complex chemical systems. Contact us for supply of Polyethylene glycol-30 dipolyhydroxystearate Request Quote
