Pearlescent dispersion with good flow properties and a low surfactant content

Claim 1

A pearlescent dispersion with good flow properties, which consists essentially of 5-30% by weight of a fatty acid glycol ester of the formula I ##STR9## in which R 1 denotes a saturated or unsaturated hydrocarbon chain with 13-21 carbon atoms, A denotes a group of the formula --C 2 H 4 -- or --C 3 H 6 --, X denotes a hydrogen atom or a group of the formula ##STR10## and m denotes a number from 1 to 10, 2-20% by weight of a fatty acid alkanolamide of the general formula II ##STR11## in which R 2 denotes a saturated or unsaturated hydrocarbon chain with 7-29 carbon atoms and R 3 and R 4 independently of one another denote a hydrogen atom or a group of the formula --C 2 H 4 OH or --C 3 H 6 OH, 0.1-10% by weight of one or more surfactants of the formulae III-VI given below ##STR12## in which R 5 denotes a linear or branched, saturated or unsaturated hydrocarbon group with 8-20 carbon atoms, n denotes a number from 0 to 10, and Y denotes an alkali metal, alkaline earth metal or ammonium ion, ##STR13## in which R 6 denotes a linear or branched, saturated or unsaturated hydrocarbon chain with 7-29 carbon atoms and n and Y have the same meaning as in formula III, ##STR14## in which R 5 and R 6 have the same meaning as in the formulae III and IV, and ##STR15## in which R 5 , R 6 and n have the same meanings as in the formulae III and IV and Z denotes a hydrogen atom or an alkyl group with 1-5 carbon atoms, 0.1 to 3% of a monovalent or divalent metal salt, and water in the amount to make up to 100%.
