    Abstract: Described are cosmetic preparations containing light-screening agents designed to protect the human epidermis against UV light in the region from 280 to 400 nm. The light-screening agents are contained in a carrier compound suitable for cosmetic purposes together with compounds of the formula (I): (see formula I) where R1 and R2 are identical or different straight-chain or branched aliphatic or cycloaliphatic radicals which are in the para and/or ortho position and have 1 to 18 carbon atoms, R1 may additionally be a hydrogen atom, and n is 1 or 2, and with compounds which absorb in the UV-B region. The above mentioned compounds of the formula I are in amounts which make them active as photostable UV-A filters.
