POLYGLYCERYL-6 POLYRICINOLEATE.

Valuable CAS 107615-51-0 / SURFACTANT - EMULSIFYING

Polyglyceryl-6 Polyricinoleate is a versatile lipophilic emulsifier and stabilizer, adept at creating stable water-in-oil emulsions. It enhances the texture of cosmetic formulations, imparting a smooth, cushioned feel while improving spreadability. Beyond its functional properties, it also provides emollient benefits to the skin.

Summary

Emulsifying Skin Conditioning Stabilizing Thickening Anticaking

Science

Mechanism of Action

This ingredient functions primarily as an emulsifier and stabilizer, leveraging its strong lipophilic structure, derived from polyglycerol and ricinoleic acid, to effectively bind immiscible oil and water phases into stable emulsions. On the skin, it contributes emollient properties, aiding in hydration and nourishment. Aesthetically, it refines formula texture, offering a lubricating feel, adding cushion, and ensuring uniform dispersion of pigments and other active ingredients.

Key findings

  1. 01 Delivers emollient and emulsifying properties, provides a smooth, lubricating skin feel, adds cushion, and improves the spreadability of lotions and creams. It effectively disperses pigments and other ingredients for consistent formulations.
  2. 02 Enables the formation of stable water-in-oil emulsions, supporting high water content in diverse product types.
  3. 03 Formulated gel emulsions exhibit relatively smaller droplet sizes and enhanced thermal stability, attributed to a dual stabilization mechanism involving Pickering interface stabilization and a continuous-phase crystal network.
  4. 04 Successfully utilized in advanced double emulsion systems (water-in-oil-in-water) to achieve enhanced encapsulation efficiency.
