    Abstract: The present invention relates to a sulfate-free aqueous concentrate comprising at least: (i) at least 25% by weight of opacifier particles selected from C16-C22 fatty acid, C16-C22 fatty alcohol, mono-, di- and tri-C16-C22 esters of glycerol, mono- and di-C16-C22 esters of ethylene glycol, diethylene glycol and triethylene glycol, C16-C22 fatty acid alkanolamides and mixtures thereof, with said particles are having a median diameter ranging from 1 to 15 μm; (ii) an amphoteric or zwitterionic surfactant, (iii) water, with the total amount of surfactants in said aqueous concentrate ranging from 0.5 to 15% by weight, relative to the total weight of the aqueous concentrate. It also relates to the use of such an aqueous concentrate as an opacifier. The aqueous concentrate of the invention may be used as an opacifier in a composition, to replace at least some of a styrene opacifier or titanium dioxide in said composition.
