Science
Mechanism of Action
It acts as a hydrophilic bridge between water and oil phases, significantly lowering interfacial tension. Its unique structure allows it to build a stable gel network within the formulation, which not only improves the delivery and spreadability of active ingredients but also aids in moisture retention by reinforcing the product's film-forming capabilities on the skin.

Key findings
- 01 Demonstrated as an essential primary emulsifier (at 1.0%) for stabilizing Japanese quasi-drug whitening formulas containing Tranexamic acid.
- 02 Validated at 0.8% in sunscreen technology to successfully stabilize high loads of UV filters while ensuring a matte, non-oily skin feel.
- 03 Research indicates that levels between 2.0% and 8.0% provide superior phase stability in lipid-rich cosmetics while maintaining a refreshing, watery texture.

Dusting Analysis
As a functional emulsifier rather than a marketing 'hero' ingredient, it is rarely 'dusted' for label claims. However, it must be used at concentrations above 0.5% to effectively stabilize complex emulsions.
The Formula
Formulation
Stability
Highly resilient across a broad pH spectrum and exhibits exceptional thermal stability up to 80°C, making it ideal for high-performance sunscreens and hair care.
Synergies
- Tranexamic acid
- UV Absorbents
- High-viscosity oils
Conflicts
- High electrolyte concentrations (may cause salting out)
- Strong oxidizing agents
Safety
Safety Profile
Considered safe when formulated to be non-irritating. Standard industry practice caps leave-on use at 5.0% to ensure maximum skin tolerance.
