of the disclosure: The invention relates to a cosmetic tanning product which, in addition to a conventional UV filter and at least one activator, contains at least one compound of the formula in which R1 is H or CH3-(CH2)X, with x being 1, 2, ... 20, and R2 is CH3CO- or CH3-(CH2)y-CO, with y being 1, 2, ... 20. Suitable activators are, on the one hand, alkali metal and/or alkaline earth metal salts of adenosine-5'-tri-, di- or mono-phosphoric acid and/or mixtures with the corresponding alkali metal and/or alkaline earth metal hydrogen phosphates of the following molecular formula: with m being 0, 1 or 2, and when m is 0 or 1 R3 being AK or 1/2 EAK, and when m is 2 R3 being H, and R4 being AK or 1/2 EAK, and AK denoting an alkali element, and EAK denoting an alkaline earth element. Equally suitable activators are butyl esters of adenosine-5'-tri-, di- or mono-phosphoric acid of the following molecular formula III with n being 0, 1 or 2, and when n is 0 or 1 R5 being Bu and when n is 2 R5 being H, and Bu denoting butyl. The UV filter, the activator(s) and the active substance(s) are, depending on the solubility, introduced into aqueous or oily solutions for the preparation of the sunscreen product, there being addition of protein hydrolysate, swelling or thickening agents, surface-active agents, emulsifiers, film-forming substances and perfume as further additives. |
