Science
Mechanism of Action
This ingredient operates by forming a stabilizing film that significantly lowers the surface tension between immiscible liquids, facilitating their integration into a uniform, stable emulsion. As a surfactant, it actively aids in lifting and removing dirt and impurities from the skin's surface. Additionally, it serves as a solubilizer, assisting in the dissolution of other formulation components, and acts as a stabilizer to maintain product integrity, potentially enhancing skin hydration and contributing to product consistency.

Stability
As a primary emulsifier, PEG-30 Glyceryl Isostearate is engineered to effectively blend and stabilize oil and water phases within formulations. Its inherently mild character ensures broad compatibility with a diverse range of cosmetic ingredients. When present as a solid (fine powder or pellets), it can further enhance product consistency and serve as a humectant, while its inherent microbiological stability may reduce the necessity for additional preservative systems.
