Description
technical field [0001] The present invention relates to a cosmetic preparation comprising octyl salicylate (ethylhexyl salicylate) and titanium dioxide having a rutile crystal structure with a primary particle size of 2-100 nm. Background technique [0002] The trend from delicate fair skin to "healthy, athletic tan" has been going on for years. To obtain such a complexion, people expose their skin to solar radiation, as this leads to the formation of pigments in the formation of melanin. However, the ultraviolet radiation of the sun also has a damaging effect on the skin. In addition to immediate damage (sunburn), long-term damage also occurs, for example an increased risk of skin cancer in the event of over-irradiation with light from the UVB region (wavelength: 280-320 nm). The excessive action of UVB and UVA (wavelength: 320-400 nm) radiation also leads to a weakening of the elastic and collagen fibers of the connective tissue. This leads to a lot of phototoxicity and...
