Film forming

The film-forming ingredients create a thin continuous layer on the surface of the skin, hair or nails. This microfilm helps to reduce moisture loss, makes the surface smoother, improves the distribution of the product and prolongs the feeling of comfort. In decorative cosmetics and sunscreen formulas, it also increases the durability of the coating, helps pigments and filters to hold more evenly and can make the texture more silky. The European CosIng database classifies film forming as an official cosmetic function, and PubChem data indicate that silicone polymers like dimethicone are used as components of skin and hair products and support the barrier properties of the surface.

On hair, such substances are especially appreciated for their ability to fix the shape, reduce fluff and protect the hairstyle from moisture. Therefore, they are often used in lacquers, mousses, styling creams and shine serums. For the skin, the film can give a more even finish, a feeling of softness and additional protection from external factors, although by itself it does not replace full-fledged care. Typical examples include PVP, a popular polymer for fixing hair, and Dimethicone, which improves gliding, softens skin and hair, and forms a protective coating. According to manufacturers of raw materials and profile databases, PVP and related polymers are used as film-forming and hair-fixing components, and dimethicone is widely used in care formulas as a conditioning and protective ingredient.
