Definitions
- the invention relates to the use of 2- (3,4-dihydroxyphenyl) -2-hydroxyacetic acid, hereinafter referred to as 3,4-dihydroxymandelic acid, as an antioxidant and / or radical scavenger for protection against ultraviolet light-induced oxidative damage.
- Ultraviolet light in particular ultraviolet light in the range from 290 to 400 nm, dissolves photooxidative processes on or in the skin e.g. from mammals or humans, different reactive oxygen compounds or radicals being formed starting from oxygen. These can e.g. Damage or destroy intracellular molecules and thus weaken the cell's vitality or even kill it.
- Radicals can also damage the intracellular molecules or structures.
- the lipid layer and the sebum which serve as a barrier against the environment, can be destroyed by oxidative processes.
- a major component of the essential sebum is squalene, which is highly unsaturated and very sensitive to oxidation.
- Antioxidants or radical scavengers which support the natural defense mechanisms against free radicals and reactive oxygen compounds in physiological systems, protect the lipid layer of the skin from oxidative processes. They also protect the oxidation-sensitive components of cosmetics, pharmaceuticals or foods from autoxidation.
- Antioxidants are substances that significantly delay or completely prevent oxidation in small concentrations compared to the oxidizable substrate. Many antioxidants act as radical scavengers and / or at the same time
- the object of the present invention is to develop active substances which, on account of their strong specific radical-catching and / or antioxidative action, can protect cells and tissues of the skin of mammals from the harmful effects of free radicals and oxidative processes.
