摘要:
A light-stable cosmetic composition for protection from UV rays having a wavelength of between 280 and 400 nm, which contains at least one tetraalkylquercetin in a cosmetically acceptable oil-based medium, and new tetraalkylquercetins.
摘要:
The invention relates to novel light protection filters for the VIS and IR region for the preparation of sunscreens and also to the use thereof in cosmetics. The invention further relates to sunscreens which have broad-band or ultraspectral protection.
摘要:
A cosmetic preparation having butylmethoxydibenzoyhmethane as a protection filter and insoluble inorganic particles which are titanium dioxide particles doped with cerium or iron ions which absorb in the UVA region and are added to improve the photostability of the cosmetic preparation.
摘要:
The invention relates e.g. to the use of aldehydes and/or ketones for improving the stability of cosmetic formulations containing butylmethoxydibenzoylmethane as organic light protection filters in conjunction with inorganic light protection filters.
摘要:
The invention relates to the use of .alpha.-hydroxyketoalkyl derivatives as light protection filters for cosmetic or pharmaceutical products, the .alpha.-hydroxyketoalkyl group being linked, if appropriate via a spacer, to a chromophoric group which has an absorption maximum in a wavelength range of between 280 and 400 nm and has a conjugated .pi.-electron system of at least 8 .pi.-electrons, and to new .alpha.-hydroxyalkyl derivatives, processes for their preparation and pharmaceutical and cosmetic formulations comprising these derivatives as light protection substances.
