Description

technical field [0001] The present invention relates to a cosmetic preparation comprising 4-(tert-butyl)-4'-methoxydibenzoylmethane (INCI: butylmethoxydibenzoylmethane) and one or more Complexing agents of the group of phosphonic, phosphoric and carboxylic acids, and / or their alkali metal salts and / or their amine N-oxides, having less than two nitrogen atoms. 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 from the formation of melanin. However, the ultraviolet radiation of the sun also has a damaging effect on the skin. In addition to acute damage (sunburn), long-term damage also occurs, such as an increased risk of developing skin cancer in the event of overexposure to light from the UVB region (wavelength: 280-320 nm). The excessive action of UVB and UVA (wavelength: 320-400 nm) radi...
