Compatibility
Works well with:
Cetyl Alcohol Glycerin Mineral Oil Caprylic/Capric Triglyceride Shea Butter Magnesium Sulfate
Polyglyceryl-2 Dipolyhydroxystearate is an oil-soluble W/O emulsifier that works best when dispersed into the oil phase before combining with the water phase. It is particularly effective in combination with co-emulsifiers such as polyglyceryl-4 isostearate or cetyl PEG/PPG-10/1 dimethicone for silicone-in-water systems. High concentrations of electrolytes in the water phase can aid or disrupt stability depending on the overall formulation design.
Formulation notes
Polyglyceryl-2 Dipolyhydroxystearate is a polyglycerol ester of polyhydroxystearic acid primarily used as a water-in-oil (W/O) emulsifier, providing stable, elegant emulsions including high-water-content creams and sunscreens. Its branched fatty acid chain contributes to emulsion stability and gives the resulting product a rich, skin-conditioning feel. It is considered a low-irritation, skin-compatible ingredient and is commonly used in mineral sunscreen formulations to disperse inorganic UV filters such as zinc oxide and titanium dioxide.
