Science
Mechanism of Action
It functions by forming a breathable, structured occlusive film that effectively mitigates transepidermal water loss (TEWL). Due to its unique 'plastic' physical properties, it provides structural integrity to formulations, preventing oil migration and stabilizing emulsions for a consistent delivery of active ingredients.

Key findings
- 01 Repeat Insult Patch Testing (RIPT) on 198 subjects confirmed the ingredient is non-sensitizing at 0.7%.
- 02 Extended RIPT studies involving over 500 subjects demonstrated no sensitization or ocular irritation at concentrations of 1.5%.
- 03 A 4-week clinical use test on 40 subjects showed zero adverse reactions when applied at 1%.

Dusting Analysis
Because this ingredient is primarily used for its structural and emollient properties, it is rarely 'dusted' for marketing purposes; its presence is usually functional. Concentrations below 0.7% may indicate a negligible impact on the formula's texture and barrier-forming capabilities.
The Formula
Formulation
Stability
Highly chemically inert and resistant to oxidation. It remains stable across standard cosmetic pH ranges but may undergo hydrolysis if exposed to environments exceeding pH 9 at elevated temperatures.
Synergies
- Lipids
- Plant oils
- Mineral UV filters
Conflicts
- Strong oxidizing agents
Safety
Safety Profile
