Description

Polyglyceryl-2 Dipolyhydroxystearate is a high-performance, non-ionic emulsifier and stabilizer derived from polyglycerol and hydroxystearic acid. This versatile compound is prized for its ability to create stable, elegant emulsions with excellent skin feel and texture, making it a cornerstone ingredient in demanding personal care and cosmetic formulations. It is particularly sought after by manufacturers in the cosmetics, skincare, and pharmaceutical industries for its superior performance in oil-in-water (O/W) systems.

Application

  • Primary Emulsifier in cosmetic creams, lotions, and sun care products for stable oil-in-water (O/W) emulsions.
  • Stabilizing Agent in color cosmetics, including foundations, BB creams, and makeup removers, to prevent phase separation.
  • Texture Enhancer in skincare serums and moisturizers, providing a rich, non-greasy, and smooth after-feel.
  • Key Ingredient in high-end decorative cosmetics for improved pigment dispersion and long-wear properties.
  • Formulation Aid in pharmaceutical topical preparations, such as creams and ointments.
  • Compatibility Booster in complex formulations containing various oils, silicones, and active ingredients.
