have the meaning cited in the claims, to methods for the production thereof, to agents containing said compounds and to their use for the functionalisation of matrices, in particular their use as skin and/or hair-binding UV filters.
The invention relates to specific cinnamic acid ascorbates and to the use thereof as UV filters which bond to the skin, and to a process for the preparation thereof, and to preparations comprising these compounds.
The invention relates to the use of at least one specific triazine or melamine and/or salt thereof as accelerator for a photoinduced reaction of 3-(4-tert-butylphenyl)-3-hydroxy-1-(4-methoxyphenyl)-propan-1-one, 1-(4-tert-butylphenyl)-3-hydroxy-3-(4-methoxyphenyl)-propan-1-one or a mixture of these compounds to give avobenzone. The invention furthermore relates to a composition comprising at least one specific triazine or melamine and to a method for the stabilisation of the UV absorption capacity of a composition by means of a mixture of at least one specific triazine or melamine together with 3-(4-tert-butylphenyl)-3-hydroxy-1-(4-methoxyphenyl)propan-1-one, 1-(4-tert-butylphenyl)-3-hydroxy-3-(4-methoxyphenyl)propan-1-one or a mixture of these compounds, particularly preferably together with 3-(4-tert-butylphenyl)-3-hydroxy-1-(4-methoxyphenyl)propan-1-one.
