Unveiling PEG-30 Dipolyhydroxystearate: A Versatile Emulsifier for Advanced Formulations

PEG-30 Dipolyhydroxystearate, a non-ionic polymeric emulsifier, stands out as a multifunctional ingredient across pharmaceutical and cosmetic industries. Chemically, it is the polyethylene glycol diester of poly(12-hydroxystearic acid), with an average of 30 to 35 ethylene oxide units in its PEG backbone, lending it unique structural advantages.

In cosmetics, it excels as a water-in-oil (W/O) emulsifier, efficiently bonding and stabilizing oil and water phases while thickening formulations. It can create stable W/O emulsions with up to 90% water content, and its ability to disperse solids like pigments makes it ideal for high-performance makeup and sunscreen products. Formulators can use it alone or in combination, with recommended dosages ranging from 0.5% to 5% depending on the product type, such as 2%-3% for regular W/O creams and 2.5%-4% for foundations.

Pharmaceutically, it plays a pivotal role in self-nanoemulsifying drug delivery systems (SNEDDS). Its saturated long-chain lipid structure resists oxidation, extending shelf life, and enhances lymphatic uptake of poorly water-soluble drugs, helping them bypass first-pass metabolism. Even under in vitro digestion conditions, over 94% of it remains intact, protecting drugs from precipitation and improving their solubility and bioavailability. Compatible with a wide range of active ingredients and excipients, it offers exceptional formulation flexibility and stability.
