Science
Mechanism of Action
Functions by lowering interfacial tension with a Hydrophile-Lipophile Balance (HLB) value of approximately 7.8, making it moderately oil-soluble. It organizes at the oil-water interface to stabilize water-in-oil (W/O) systems and acts as a wetting agent to ensure uniform distribution of active ingredients across the skin surface.

Key findings
- 01 Sensitization studies on guinea pigs confirmed the ingredient as a non-sensitizer even at high concentrations of 50%.
- 02 Demonstrated effective and gentle removal of lipid-based impurities without compromising skin barrier integrity at concentrations between 1.6% and 2.0%.

Dusting Analysis
As a functional emulsifier rather than a 'hero' active, this ingredient is rarely 'dusted.' It is typically used at levels required for formula stability, ranging from 0.1% in leave-on products to 3% in rinse-off systems.
The Formula
Formulation
Stability
Maintains structural integrity in acidic environments but is susceptible to hydrolysis in alkaline conditions (pH > 8.0). It remains stable in varying water hardness levels.
Synergies
- High HLB surfactants
- Mineral oils
- Silicone elastomers
Conflicts
- Strong oxidizing agents
- Highly alkaline environments (pH > 8)
Safety
Safety Profile
Manufacturing processes must involve strict vacuum stripping to ensure the absence of 1,4-dioxane byproducts.
