The present invention provides novel diol compounds, novel cosmetic or dermatological sunscreen compositions containing these compounds and the use of the novel compounds as UV-filters. The compounds are particularly advantageous, because they adhere to the skin and therefore provide sunscreen protection for a prolonged period of time.

UV-filter compounds

The invention provides a conjugate comprising a hyperbranched polymer covalently bonded to at least three UV absorbing chromophores having an UV absorption maximum &#x3bb;&#x2267;270 nm. The conjugate is an effective and safe sunscreen which can advantageously be used in cosmetic compositions.

UV absorbing chromophores covalently bonded to hyperbranched polymers

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 invention relates to methods for the production of polymer carrier materials for solid phase synthesis, particularly for peptide synthesis. (Meth)acrylamide derivatives based on carbon hydrates, which can also contain other protective groups, are polymerized by means of suspension polymerization in an aqueous phase, optionally with the addition of pore-forming additives, and subsequently the protective groups are fully or partially cleaved. It is thus possible to obtain polymer carriers whose morphology (particle size, porosity), degree of cross-linking and swelling capability in aqueous and organic media can be adjusted in a targeted manner and whose reactive groups offer multiple opportunities for the immobilization of anchor groups and protective groups. The hydroxyl groups of the polymer carrier can be activated according to usual methods of solid phase synthesis.
