Science
Mechanism of Action
Forms a continuous, flexible film upon application that adheres to the skin surface through polymer chain entanglement. The copolymer's large molecular structure prevents stratum corneum penetration while creating a protective barrier that enhances pigment adhesion and product durability. When neutralized with bases, its carboxylic acid groups increase water dispersibility, allowing for customizable film properties.

Dusting Analysis
As a functional film-forming agent with established safety data, this ingredient is typically used at appropriate concentrations rather than being subject to dusting practices.
The Formula
Formulation
Stability
Enhanced water dispersibility achieved through neutralization of carboxylic acid groups with bases. Forms clear to turbid dispersions depending on neutralization degree and pH conditions.
Conflicts
- strong acids
- cationic surfactants when copolymer is anionic
- multivalent metal ions
Safety
