Science
Mechanism of Action
This ingredient functions by significantly lowering the interfacial tension between diverse components, acting as an efficient emulsifier, surfactant, and solubilizer. This capability allows for the stable integration of oil-based ingredients within aqueous systems, preventing phase separation and contributing to a consistent product texture. Its structure also imparts skin conditioning properties, enhancing the skin's feel.

The Formula
Formulation
Stability
Polyglyceryl-10 Heptacaprylate, as part of the polyglyceryl-10 ester family, demonstrates general stability, particularly within a pH range of 5.0-7.0. It is an effective oil-in-water emulsifier and serves as an emulsion stabilizer. The ingredient can be dispersed in hot water and shows solubility in various vegetable oils and silicones.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that the broader family of Polyglyceryl Fatty Acid Esters, which includes Polyglyceryl-10 Heptacaprylate, is safe for cosmetic application when formulated to be non-irritating. The polyglycerin-10 backbone itself has also been deemed safe by CIR. While a specific maximum concentration for Polyglyceryl-10 Heptacaprylate is not explicitly stated, related polyglyceryl-10 esters are commonly utilized at concentrations between 1% and 10% and are associated with a low risk of irritation and non-comedogenicity.
