POLYGLYCEROL-10 HEXACAPRYLATE/CAPRATE.

Valuable / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, SURFACTANT - CLEANSING

POLYGLYCERYL-10 HEXACAPRYLATE/CAPRATE is a multi-functional ester derived from polyglycerol and caprylic/capric acids, serving as an emollient, emulsifier, solubilizer, and surfactant. It supports skin barrier health, stabilizes complex formulations, and facilitates gentle yet effective cleansing.

Science

Mechanism of Action

This ingredient functions synergistically to improve skin condition and formulation stability. As an emollient, it provides exogenous lipids, enhancing the skin's natural barrier properties and contributing to a softer, smoother skin texture. Its emulsifying capabilities stabilize oil and water components, forming uniform and stable emulsions. As a surfactant, it effectively lowers surface tension, allowing for the dissolution and removal of oil and impurities from the skin. Furthermore, it acts as a solubilizer, enabling oil-soluble ingredients, such as fragrances, to integrate seamlessly into water-based systems, while also drawing moisture to the skin to aid in recovery from dryness.

Stability

Appearing as a clear to pale yellow or hazy yellow to amber viscous liquid, this ingredient is primarily soluble in alcohol (ethanol), isopropyl alcohol, vegetable oils, and silicones. While insoluble in water, it can be readily dispersed in hot water. It effectively functions as an oil-in-water (O/W) emulsifier, co-emulsifying agent, and emulsion stabilizer. It is also valued as a fragrance solubilizer and foam stabilizer, offering a PEG, PPG, and Chlorine-free alternative to traditional polysorbates.
