Abstract: 2-Cyanoacrylic esters (I) of alpha , omega -bis(4-hydroxy-2,2,6,6-tetramethylpiperid-1-yl)alkanes or (cyclo)aliphatic polyols of the given formula (I) are new. R , R = the radical of an iso- or heterocyclic ring system with at least one iso- or heteroaromatic ring and ≥ 1 of R and R is not H, n = 2-10, if n = 2, X = a gp. of formula (II), m = 2-8; if n = 3-10, X = the radical of an n-hydric 3-20C (cyclo)aliphatic polyol, opt. with 1 or 2 heteroatoms in the cycloaliphatic gp. and up to 8 non-adjacent O or S atoms or -NH- or 1-4C alkylimino gps. in the aliphatic chain. Also claimed are various materials stabilised against the action of light, O2 and heat with (I).

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.
