ABSTRACT:
A high-concentration pearling agent dispersion is disclosed. The dispersion comprises as essential components, at a specific proportion, a fatty acid glycolic ester of formula (I): ##STR1## wherein R.sub.1 represents a linear or branched, saturated or unsaturated hydrocarbon group of a C.sub.13-21 carbon atom content, Y represents a hydrogen atom or a ##STR2## group, m indicates a value of 1 to 3, which is the average number of ethylene oxide group addition moles; an alkylsulfosuccinate or a polyoxyalkylenealkylsulfosuccinate of formula (II): ##STR3## wherein R.sub.2 represents a linear or branched alkyl group of a C.sub.8-20 carbon atom content, R.sub.3 represents a hydrogen atom or a methyl group, M represents an alkali metal, an alkali earth metal, an ammonium ion, an alkyl group-substituted ammonium with the alkyl group having a C.sub.1-3 carbon atom content, or a hydroxy alkyl group-substituted ammonium with the hydroxy alkyl group having a C.sub.2-3 carbon atom content, n indicates a value of 0 to 8, which is the average number of addition moles; a fatty acid dialkanol amide of formula (III): ##STR4## wherein R.sub.4 represents a linear or branched, saturated or unsaturated hydrocarbon goup of a C.sub.7-17 carbon atom content, and R.sub.5 and R.sub.6 independently represent a group --C.sub.2 H.sub.4 or --C.sub.3 H.sub.6 ; and water. The pearling agent dispersion comprises uniformly shaped crystals, has a low viscosity, and exhibits a superior stability at high and low temperatures.
