Polyglyceryl dipolyhydroxystearate

Polyglyceryl dipolyhydroxystearate (CAS 156531-21-4 ), also marketed as Polyglyceryl-2 Dipolyhydroxystearate, is a polyglycerol ester of polyhydroxystearic acid used primarily as a water-in-oil emulsifier and rheology modifier.

It stabilizes emulsions and controls viscosity across cosmetic, food, and industrial formulations. In personal care, it anchors water-in-oil emulsions in sunscreens, foundations, and long-wear skin creams.

This ingredient delivers stable, non-greasy textures that hold up under high pigment or UV-filter loads. Food manufacturers use it as a dispersing and emulsifying agent in chocolate coatings and fat-based confectionery systems.

In these food applications, it reduces viscosity and improves flow during processing. In color cosmetics, it suspends and disperses pigments uniformly within anhydrous or low-water formulations, preventing separation over shelf life.

Coatings and adhesive formulators use it to stabilize pigment dispersions and modify the rheological profile of oil-based systems. Polyglyceryl dipolyhydroxystearate is supplied as a viscous liquid or soft paste.

The physical state depends on the specific grade and temperature. Food-grade and cosmetic-grade specifications are available, with cosmetic grades commonly meeting COSMOS or Ecocert certification requirements.

It is typically offered in drum and IBC quantities suited to industrial-scale formulation. This versatile ester provides reliable performance across a wide range of temperature and pH conditions in diverse manufacturing sectors.
