Science
Mechanism of Action
The ingredient utilizes an Isophorone Diisocyanate (IPDI) backbone for exceptional skin adhesion and durability. This structural framework is coupled with dicaprolactone and ethoxyacrylate segments which provide flexibility and hydrophobic properties, creating a breathable lattice on the skin's surface that prevents Transepidermal Water Loss (TEWL) and repels water and friction.
Research
Clinical Evidence
High confidence7.5%
Key findings
- 01 In vivo performance testing indicates significant improvements in film gloss and transfer resistance when used between 1% and 10%.
- 02 TEWL measurements demonstrate that the substantive film formed by this polymer provides measurable skin barrier reinforcement.
- 03 Safety assessments confirm a maximum efficacy and safety threshold of 7.5% for leave-on skincare applications.
Transparency
Dusting Analysis
As a functional film-former, concentrations below 1% are generally insufficient to provide the technical benefits of water resistance or barrier protection, making low-level inclusions purely 'label-claim' additions.
The Formula
Formulation
Stability
Highly stable within the oil phase of emulsions. Avoid extreme pH conditions (below 3.0 or above 9.0) to prevent potential hydrolysis of the ester-containing segments.
Synergies
- Hydrophobic pigments
- Mineral UV filters
- Emollient oils
Conflicts
- High concentrations of short-chain alcohols
- Strong oxidizing agents
Safety
Safety Profile
Reviewed as safe when formulated to be non-sensitizing; residual monomers are typically non-detectable in the finished polymer.
