Science
Mechanism of Action
As a nonionic surfactant with a low Hydrophilic-Lipophilic Balance (HLB) of approximately 4, it reduces interfacial tension to create robust emulsified systems. Beyond stabilization, it acts as a penetration enhancer, optimizing the delivery of active molecules through the lipid barrier.

Key findings
- 01 Demonstrated significant enhancement in the delivery and skin-barrier penetration of corticosteroids when used at 1.0%–2.5% in glycol-based systems.
- 02 Confirmed as non-sensitizing and non-irritating in Human Repeated Insult Patch Tests (HRIPT) even at high concentrations.

Dusting Analysis
Because it is a functional texture-builder rather than an active ingredient, it is rarely 'dusted' for marketing. However, levels below 1.0% may be insufficient for its primary role in emulsion stabilization.
The Formula
Formulation
Stability
Exhibits exceptional resistance to hydrolysis; highly effective for maintaining formula viscosity in high-heat environments (above 40°C).
Synergies
- Glycols
