POLYGLYCERYL-10 DECASTEARATE.

Valuable CAS 39529-26-5 / SKIN CONDITIONING

Polyglyceryl-10 Decastearate is a versatile polyglyceryl fatty acid ester, expertly designed to stabilize oil-in-water formulations as an effective emulsifier. Beyond its formulation benefits, it acts as a comprehensive skin conditioning agent, providing essential hydration, softening, and support for the skin's natural barrier. It also functions as a mild surfactant, aiding in gentle cleansing while maintaining skin integrity.

Science

Mechanism of Action

Functioning as an amphiphilic molecule due to its hydrophilic polyglyceryl and lipophilic stearic acid components, Polyglyceryl-10 Decastearate proficiently creates stable emulsions by facilitating the uniform dispersion of oil and water phases. On the skin, it delivers conditioning benefits by attracting and retaining moisture, thus minimizing transepidermal water loss and promoting a softer, healthier complexion. As a surfactant, it assists in dislodging impurities and excess oil from the skin's surface without compromising its vital moisture barrier. Additionally, it may contribute to formula viscosity as a mild thickening agent and enhance hydration through humectant properties.

Stability

A closely related ester, Polyglyceryl-10 Stearate, demonstrates excellent resistance to both salt and acid, suggesting similar robustness for Polyglyceryl-10 Decastearate. It disperses easily in water and exhibits hygroscopic properties. When incorporated into water-containing formulas, it has the potential to form a cyclopolymerized structure capable of locking water within a cage, indicating highly stable and long-lasting moisturizing effects.
