Science
Mechanism of Action
This graft copolymer forms a soft, flexible, and breathable barrier upon application, effectively repelling water and oil. Its behenyl (C22) chain also contributes wax-like properties, optimizing sensory texture and formulation stability.

Formulation
Stability
Highly stable in anhydrous systems and water-in-oil emulsions. It has a melting point of 45-55°C, providing structural integrity to stick products, and is stable with UV absorbers.
Synergies
- Polyether-modified silicone surfactants (for improved emulsion stability)
Conflicts
- Purely water-based systems without emulsifiers
- Strongly cationic ingredients (potential for precipitation with anionic variants)
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) assessed this class of acrylates copolymers as safe for use up to 25% in leave-on dermal products. Human Repeated Insult Patch Tests on 47 subjects confirmed it to be non-irritating and non-sensitizing at 25% dilution.
