Science
Mechanism of Action
This ingredient utilizes a specialized 'T-propyl' resin structure to create a semi-occlusive, non-transferable barrier. It anchors pigments and active ingredients to the skin's surface, effectively reducing trans-epidermal water loss (TEWL) and shielding the complexion from environmental pollutants while simultaneously refining the formula's texture to eliminate tackiness.
Research
Clinical Evidence
High confidence4.5%
Key findings
- 01 Human Repeated Insult Patch Testing (HRIPT) confirmed the ingredient is non-sensitizing and non-irritating, even in delicate eye-area applications.
- 02 In vitro genetic toxicity assessments (Ames test) demonstrated zero mutagenic potential.
Transparency
Dusting Analysis
As a structural and film-forming agent, it is typically used at functional levels (1-5%) to achieve the desired texture and transfer-resistance. Concentrations below 0.5% are generally insufficient to provide the characteristic breathable barrier.
The Formula
Formulation
Stability
Highly stable across a broad pH range; requires heating to 70°C for proper phase integration due to its 66°C melting point.
Synergies
- Volatile silicones
- Organic UV filters
- Mineral pigments
Conflicts
- Purely water-based serums without emulsifiers
