Science
Mechanism of Action
Upon application, the solvent evaporates, causing the polymer chains to interlock into a resilient, flexible lattice. This breathable yet water-insoluble matrix locks active ingredients and pigments in place while providing a subtle mechanical tension that translates to a perceptible lifting or firming effect on the skin's surface.
Research
Clinical Evidence
High confidence6.8%
Key findings
- 01 A Human Repeat Insult Patch Test (HRIPT) involving 52 participants confirmed that concentrations of 6.8% and higher demonstrate no potential for dermal irritation or sensitization.
- 02 Safety reviews by the CIR Expert Panel validated that leave-on dermal applications remain non-sensitizing even at concentrations up to 25%.
Transparency
Dusting Analysis
As a functional texture and film-forming agent, it is typically used at effective concentrations to achieve specific wear-time goals; however, inclusion below 1% in 'long-wear' marketed products may indicate 'angel dusting' for marketing purposes.
The Formula
Formulation
Stability
Highly hydrolytically stable and resistant to degradation. It is typically integrated into the oil phase as a 50% solution in Isododecane.
Synergies
- Isododecane
- Mineral UV filters
- Hydrophobic pigments
Conflicts
- Highly polar aqueous systems lack compatibility without robust emulsification
- Strong oxidizing agents
Safety
Safety Profile
While safe up to nearly 99% in nail technology, dermal leave-on use is restricted to 25% to maintain its non-irritant profile.
