Bio derived hydrophobic films for keratin materials
Innovative bio based hydrophobic films offer a lightweight, silicone free moisture barrier for keratin rich fibers and skin. Utilizing plant derived waxes and fatty acids, these films provide moisture repellency while maintaining natural texture and breathability.
Overview
This cutting-edge innovation introduces a bio based, silicone free hydrophobic film designed to protect keratin rich fibers and skin. By utilizing a blend of plant derived waxes and fatty acids, this formulation creates an ultra thin, lightweight barrier that effectively repels moisture. Unlike traditional moisture barriers, this film maintains the natural texture and feel of keratin materials without being heavy or occlusive, ensuring breathability and comfort.
Technical specifications
Key features:
- Bio based formulation: Utilizes plant derived waxes and fatty acids, avoiding silicone use
- Lightweight and breathable: Provides a moisture barrier without occlusion or heaviness
- Effective moisture repellency: Demonstrated uniform coating and water resistance on model substrates
- Durability: Evaluated for condensation behavior and humidity resistance on keratin substrates
The formulation is prepared using melt processing, ensuring a uniform and continuous coating that maintains repellency over multiple humidity cycles. The focus on natural materials ensures compatibility with keratin surfaces while supporting smoothness and enhanced humidity resistance.
Technology readiness level
This technology is currently at TRL 4, with laboratory scale validation on model substrates. Future work involves optimizing the formulation for keratin surfaces, assessing durability, and refining adhesion and sensory profiles under varied humidity conditions.
