The invention provides a process for producing microcapsules with UV filter activity, wherein at least one type of crosslinkable chromophore with UV-A and/or UV-B and/or UV-C filter activity and optionally at least one type of crosslinkable monomer which does not have UV-A and/or UV-B and/or UV-C filter activity are subjected to a crosslinking reaction in the absence of non-crosslinkable chromophores with UV-A and/or UV-B and/or UV-C filter activity and microcapsules obtainable by this process.

Microcapsules with UV filter activity and process for producing them

The present invention relates to novel sunscreens on the basis of polysiloxanes, to their preparation and to their use, especially in formulations for the protection against harmful effects of sunlight.

Polysiloxane sunscreens

The present invention relates to novel 1,4-dihydropyridine derivatives, to novel cosmetic or dermatological sunscreen compositions containing these derivatives and the use of these derivatives for photoprotecting human skin and/or hair against UV radiation, in particular solar radiation.

Ionic UV-A sunscreens and compositions containing them

1,4-dihydropyridine and 1,4-dihydropyrane derivatives and novel cosmetic or dematological sunscreen compositions containing novel and/or known 1,4-dihydropyridine or 1,4-dihydropyrane derivatives which are useful for photoprotecting human skin and/or hair against UV radiation, in particular solar radiation, and the use of such 1,4-dihydropyridine and/or 1,4-dihydropyrane derivatives as UV-A screening agents, particularly in cosmetic and pharmaceutical compositions.

Sunscreen compositions as well as dihydropyridines and dihydropyranes

The present invention relates to organosilicone derivatives of amino hydroxybenzophenones, a process for their preparation thereof, a cosmetic compositions comprising the organosilicone derivative and the use thereof for protecting hair and/or skin from damage caused by UV-A irradiation.

Organosilicone derivatives of amino hydroxybenzophenones and their use as UV-A filters in cosmetic preparations

The present invention relates to new &agr;,&bgr;-unsaturated ketones of formula I. The new compounds exhibit an intense, very long lasting green galbanum-type odor with fruity undertones. Compositions containing these novel compounds are also provided.
