Nacreous lustre concentrates in the form of a pourable aqueous dispersion with 5 to 50 wt.%. of nacreous lustre-forming components and 5 to 55 wt.% of emulsifiers containing as emulsifiers fatty acid-N-alkyl polyhydroxy alkyl amides of general formula (I), in which R<1>-CO is an aliphatic acyl radical with 6 to 22 carbon atoms, R<2> is hydrogen, an alkyl or hydroxylalkyl radical with 1 to 4 carbon atoms and R<2> is 2 linear or branched polyhydroxyalkyl radical 3 to 12 carbon atoms and 3 to 10 hydroxyl groups, are distinguished by a particularly brilliant nacreous lustre. The concentrates may contain other emulsifiers and preferably low-molecular polyvalent alcohols. |
