Science
Mechanism of Action
Functions as a graft copolymer where polyacrylate backbone segments provide strong skin adhesion and sebum resistance, while silicone side chains contribute water repellency and oxygen permeability. Upon solvent evaporation, it forms a uniform, flexible film that anchors active ingredients and pigments to the skin surface without compromising breathability.

Transparency
Dusting Analysis
High molecular weight and specialized film-forming function make dusting unlikely; requires specific dissolution methods for proper incorporation
The Formula
Formulation
Stability
Chemically inert with excellent heat and UV stability; requires pre-dissolution in volatile silicones or hydrocarbons before oil phase incorporation
Synergies
- Cyclopentasiloxane for dissolution
- Isododecane for carrier compatibility
- UV filters for enhanced adhesion
Conflicts
- Highly polar alcohols
- Strong oxidizing agents
- High concentrations of anionic surfactants
Safety
Safety Profile
Non-sensitizing and non-irritating due to high molecular weight preventing skin penetration; maximum 25% in leave-on makeup products
