Science
Mechanism of Action
This ingredient primarily functions as a water-in-oil (W/O) emulsifier, leveraging its unique molecular structure to create stable interfaces between disparate water and oil phases. It effectively binds these components, ensuring a consistent product texture and preventing separation. Furthermore, it acts as a thickening agent, contributing to a smooth, creamy feel. On the skin, it aids in hydration by forming a barrier that minimizes transepidermal water loss and by slowly releasing moisture. Its properties also suggest potential benefits in controlling fungal growth, making it suitable for formulations targeting fungal acne.

The Formula
Formulation
Stability
A robust nonionic W/O emulsifier, stable across neutral, mildly acidic, and mildly alkaline pH systems. It exhibits significant resistance to high electrolyte concentrations and ethanol. For optimal performance in achieving heat-stable water-in-oil emulsions, high-temperature emulsification is suggested.
Conflicts
- Application on damaged or compromised skin should be strictly avoided.
- Formulations must implement stringent controls to ensure minimal presence of potential impurities, specifically ethylene oxide and 1,4-dioxane.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that PEG-30 Dipolyhydroxystearate, along with other PEG diesters, is safe for use in cosmetics when formulated to be non-irritating. This assessment is further recognized by regulatory authorities such as the European Union's Cosmetics Regulation. It is generally considered non-toxic, non-irritating to eyes and skin, and carries a low potential for skin sensitization. However, individuals with highly sensitive skin are advised to perform a patch test prior to widespread use. It must not be applied to compromised or damaged skin. Manufacturers bear the responsibility of ensuring the removal of impurities like ethylene oxide and 1,4-dioxane from the final ingredient.
