Science
Mechanism of Action
As a multi-functional hydrocolloid, it organizes the aqueous phase of a formula to increase viscosity and stabilize oil-in-water emulsions. Upon application, it creates a lightweight, continuous film that reinforces the skin's natural barrier, protecting against environmental pollutants while optimizing moisture retention through reduced transepidermal water loss.
Research
Clinical Evidence

Key findings
- 01 Clinical evaluation of mist formulations confirms functional stabilization and uniform distribution at concentrations as low as 0.2%.
- 02 Usage data indicates that a 1-5% concentration range is ideal for achieving optimal thickening and gelling properties in cosmetic structures.

Dusting Analysis
Since dehydroxanthan gum is a functional texturizer rather than a marketing 'hero' active, it is rarely 'dusted.' However, levels below 0.1% may be insufficient to provide meaningful structural stability to a complex emulsion.
The Formula
Formulation
Stability
Exhibits exceptional stability across a broad pH spectrum; viscosity remains consistent (less than 10% variance) between pH 3 and 11. It is highly resistant to thermal degradation and freezing cycles. For optimal hydration, it should be pre-dispersed in a humectant slurry like glycerin.
