Abstract: Solubilizers are described which comprise a) one or more ethoxylated fatty alcohols according to formula (I) in which R1 is a linear or branched alkyl radical having 6 to 12 carbon atoms and n is on average a number from 2 to 12, b) one or more ethoxylated triglycerides whose acyl radicals are derived from linear or branched saturated fatty acids having 6 to 22 carbon atoms, and c) water and which are liquid and clear at room temperature and do not comprise addition products of ethylene oxide and simultaneously propylene oxide onto fatty alcohols. The solubilizers are suitable in particular for producing cosmetic, dermatological or pharmaceutical formulations.

Abstract: A description is given of cosmetic, dermatological and/or pharmaceutical compositions comprising at least one copolymer A containing a) 1% to 50% by weight of structural units originating from N-vinylcaprolactam, b) 49.99% to 98.99% by weight of repeating structural units of the formula (1) in which R3 is hydrogen, methyl or ethyl, Z is C1-C8 alkylene and X+ is Li+, Na+, K+, Mg2+/2, Ca2+/2, Al3+/3, NH4+, monoalkylammonium, dialkylammonium, trialkylammonium or tetraalkylammonium, the alkyl substituents of the ammonium ions being independently of one another (C1-C22) alkyl radicals or (C2-C10) hydroxyalkyl radicals, or singly to triply ethoxylated ammonium compounds having the same or different degree of ethoxylation, it being possible also for two or more different structural units of the formula (1) to be present in the copolymer, and c) 0.01% to 8% by weight, preferably 0.01% to 5% by weight, of crosslinking structures originating from monomers having at least two olefinic double bonds.
