Science
Mechanism of Action
This ingredient functions as an interfacial stabilizer, reducing surface tension to create ultra-fine, uniform emulsions. In cleansing systems, it organizes into micelles to encapsulate and lift debris, while in sunscreens, it acts as a dispersing agent that ensures inorganic filters are distributed evenly for consistent UV protection and enhanced water resistance.

Clinical Evidence
High confidence2%
Key findings
- 01 Clinical data indicates that a 2.0% concentration successfully stabilizes oil-in-water moisturizing serums with high dermatological tolerance.
- 02 Formulation research demonstrates its utility as a co-emulsifier for maintaining the integrity of sensitive actives like Ectoin and Vitamin C.

Dusting Analysis
As a functional emulsifier rather than a standalone active, 'dusting' is less common; however, concentrations below 1% may indicate it is used merely as a secondary stabilizer rather than the primary emulsifying system.
The Formula
Formulation
Stability
Exhibits exceptional versatility across a broad pH range; it is specifically effective in acidic environments (pH 3-5) where other emulsifiers often fail.
