Science
Mechanism of Action
This ingredient functions as an amphiphilic molecule, bridging the gap between oil and water phases in a formulation. The polyglycerin-6 component provides hydrophilicity, while the cocoa butter-derived fatty acids (primarily stearic, palmitic, and oleic acids) provide lipophilic emolliency. Upon application, it integrates into the stratum corneum to support lipid barrier cohesion and reduce transepidermal water loss (TEWL) while acting as a gentle solubilizer for other active lipids.

Dusting Analysis
While rarely 'dusted' in the traditional sense of high-cost actives, it is sometimes used at sub-0.5% levels purely to claim 'Cocoa Butter' on a label for marketing purposes in water-based serums where true cocoa butter would be incompatible.
