The innovative films are obtained by solvent casting of a solution containing snail slime in appropriate concentrations
mixed with polymeric solutions. Renowned for its functional properties, the snail slime reduces rigidity and fragility of
the films, while drastically enhancing film ductility, flexibility, stretching and adhesiviness. Consequently, the fruit of
the research is extremely versatile and adaptable to the different applications it was designed for.
The final product is an adhesive film for mucosae, skin (patch-non patch) or nails which does not release microplastics
in the environment unlike other existing solutions on the market. In addition, films containing snail slime are edible and
thus suitable for applications in food packaging.

APPLICATIONS:

  • Cosmetics, e.g. anti-cellulite bandages, anti-wrinkle and moisturizing films, anti-aging and anti-stretch mark treatments;
  • Pharmaceutics, e.g.healing patches/films, antibacterial, antifungal, anesthetics drugs and painkillers.
  • Food, e.g. food packaging

ADVANTAGES:

  • Easy scaling up of the method;
  • No solvents used other than water;
  • Basic matrix versatility for a specific use;
  • Green solution preventing from microplastics release in environment;
  • Fully biodegradable.

The group of inventors will be present at SMAU taking place in Milano on 22-24th of October showcasing their prototypes.
