Pourable nacreous lustre concentrate

A pearlescer concentrate in the form of a free flowing aqueous dispersion consisting essentially of:

• (a) 5 to 50% by weight of a pearlescing component selected from the group consisting of
• (1) a compound of formula (II):
• R.sup.3 --(OC.sub.n H.sub.2n).sub.x --OR.sup.4 (II)
• or mixtures thereof, wherein R.sup.3 is a fatty acyl group having 14 to 22 carbon atoms, R.sup.4 is hydrogen or linear fatty acyl group having 14 to 22 carbon atoms, n is 2 or 3, and x is 1;
• (2) a compound of formula (III):
• R.sup.5 --CO--NH--X (III)
• or a mixture thereof, wherein R.sup.5 is an alkyl group having 8 to 22 carbon atoms and X is selected from the group consisting of --CH.sub.2 --CH.sub.2 --OH, --CH.sub.2 --CH.sub.2 --CH.sub.2 --OH, and --C(CH.sub.3).sub.2 --OH;
• and
• (3) a linear saturated fatty acid having 12 to 14 carbon atoms;
• (b) 5 to 55% by weight of a nonionic emulsifier of formula (I):
• ##STR5## or a mixture thereof as the sole emulsifier, in which formula (I) R.sup.1 --CO is an aliphatic acyl group having 6 to 22 carbon atoms, R.sup.2 is an alkyl or hydroxyalkyl group having 1 to 4 carbon atoms, and R.sup.z is a linear or branched polyhydroxyalkyl radical having 3 to 12 carbon atoms and 3 to 10 hydroxyl groups;
• and
• (c) 0.1% to 40% by weight of a low molecular weight polyhydric alcohol.
