Definitions

• the invention relates to the use of at least one ascorbic acid derivative for the functionalization of matrices, and more particularly
• the functionalization according to the invention of proteinaceous matrices is effected by covalent anchoring or strong electrostatic interaction.
• a preferred field of application of the use according to the invention is the UV protection.
• Human skin is subject to certain aging processes that are partly due to intrinsic processes (chronoaging) and partly due to exogenous factors (environmental, e.g., photoaging).
• the exogenous factors include, in particular, sunlight or artificial radiation sources with a comparable spectrum and compounds which can be formed by the radiation, such as undefined reactive photoproducts, which can also be free-radical or ionic.
• UV filters and antioxidants There are a variety of organic and inorganic UV filters and antioxidants known that can absorb UV radiation and trap free radicals. They are thus able to protect human skin. These compounds catalyze the transformation from UV light to heat. Due to lack of skin adhesion but the protection period is limited, especially because conventional UV filters can be washed off very easily, for example, sweat or water. It is a strategy known, for example, from WO 2006/018104 to derivatize UV filters or self-tanning substances in such a way that they can bind covalently to the stratum corneum of the epidermis via a reactive molecular part and thus functionalize the skin with the UV filter or self-tanner.
• UV filter derivatives or derivatives of other active substances such as pharmacological, antimicrobial, fungicidal, herbicidal, insecticidal or cosmetic active ingredients, X-ray contrast agents or dyes, as high as possible Reactivity of their bondable moieties have.
