Science
Mechanism of Action
This ingredient functions primarily as an advanced film-former. Upon application, it establishes a hard, tough, and flexible film on the skin, derived from its polynorbornene backbone modified with a silicone group. When the composition dries, this film exhibits a distinct shrinkage and adhesive property, which physically stretches skin wrinkles to reduce their visibility and provides a lifting effect for sagging areas. The resulting film also demonstrates superior resistance to bending and cracking, ensuring it maintains its integrity and adhesion while conforming to facial movements. Additionally, its inherent oil and water repellency contributes to enhanced cosmetic longevity and resistance to color transfer, while imparting a smooth, non-tacky skin feel.

Key findings
- 01 A patent filing (EP 4129417 A1) demonstrates that compositions containing this copolymer form a skin-adherent film upon drying. This film induces a contractile effect, physically stretching wrinkles to reduce their prominence and providing a lifting action for sagging skin. The film's robust bend resistance ensures it maintains integrity and adhesion without cracking, even with skin movements. Effective concentrations of the solid copolymer content range from 1-28 mass%, with optimal effects observed at 5-18 mass%.

Stability
This copolymer, when incorporated into silicone products, may degrade upon exposure to heat, light, or extreme pH conditions (both acidic and alkaline). For optimal stability, it is recommended to store tightly sealed in a cool, dark environment, protected from heat and open flame.
Safety
Safety Profile
Comprehensive safety assessments by major regulatory bodies such as CIR, SCCS, or FDA are not publicly available for this specific copolymer. Information regarding compliance or specific safety data for the raw material is limited. Manufacturers indicate that while these silicone products are utilized in cosmetics, they are primarily designed for general industrial applications and are not intended for medical or surgical purposes. Consultation of Material Safety Data Sheets (MSDS) is advised for safe handling and specific product use.
