Polyglyceryl-2 dipolyhydroxystearate    is a naturally occurring chemical compound obtained by the reaction of glycerine with stearic or isostearic acid.

The name describes the structure of the molecule:

• Polyglyceryl-2 indicates a polymeric molecule derived from glycerol, a three-atom alcohol. This component provides emulsifying and stabilizing properties to the compound.
• dipolyhydroxystearate refers to a modified form of stearic acid, a saturated fatty acid. The modification introduces additional hydroxyl groups, enhancing solubility and water-binding capacity.

Raw Materials Used in Production.

Polyglyceryl-2 Dipolyhydroxystearate is a synthetic emulsifier and stabilizer derived from the combination of polyhydroxylated fatty acids (like stearic acid) and polyethoxylated glycerin.

Step-by-step Summary of Industrial Production Process.

• Production of polyethoxylated glycerin through the polymerization of glycerol.
• Reaction of polyethoxylated glycerin with stearic acid or similar fatty acids to form the compound.
• Purification of Polyglyceryl-2 Dipolyhydroxystearate to remove impurities and reaction by-products.
• Quality control to ensure the product meets required standards.

Form and Color

Polyglyceryl-2 Dipolyhydroxystearate typically appears as a paste or viscous liquid, ranging in color from white to light yellow.

What it is used for and where

Cosmetics

Skin conditioning agent. It is the mainstay of topical skin treatment as it has the function of restoring, increasing or improving skin tolerance to external factors, including melanocyte tolerance. The most important function of the conditioning agent is to prevent skin dehydration, but the subject is rather complex and involves emollients and humectants that can be added in the formulation.

Used as an emulsifier, viscosity controller, dispersant and stabiliser in creamy oil/water emulsions in skin and hair care products.

In chemical products for oral hygiene, sunscreens.
