What is 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.
Where is Polyethylene glycol-30 dipolyhydroxystearate used?
- Personal care: stable emulsions in sunscreens and lotions, including high oil-phase loads and UV filters
- Pharmaceutical: solubilisation and dispersion of poorly water-soluble actives in topical and oral dosage forms
- Textile processing: wetting and dispersing agent improving dye penetration and surface uniformity on synthetic fibres
- It stabilises oil-in-water and water-in-oil emulsions in industrial formulations.
Good to know: Handling characteristics vary by temperature. Cosmetic-grade and pharmaceutical-grade specifications are available, the latter often aligning to excipient standards for topical and oral formulations.
Commercial specifications
- Bulk supply in drum or container quantities
- Smaller packaging for formulation development
