ABSTRACT:
A premix composition suitable for the preparation of thicknened aqueous compositions by dilution with water, containing (i) an amine, selected from the group consisting of primary amines, secondary amines, tertiary amines, diamines, and amines in the form of a heterocyclic ring, wherein the primary, secondary, tertiary amines, and diamines carry at least one nitrogen linked hydrocarbon group which represents a saturated or unsaturated linear or branched alkyl group having at least 10 carbon atoms or an aryl, aralkyl or alkaryl containing up to 24 carbon atoms, and wherein the other nitrogen linked groups may be different or the same and represents hydrogen, substituted or unsubstituted alkyl groups, aryl groups, aralkyl groups or polyalkoxy groups containing 1-3 alkoxy groups, or wherein when the amine selected is in the form of a heterocyclic ring, it contains at least two nitrogen atoms, one of which being substituted by amino (lower) alkyl or hydroxy (lower) alkyl, which optionally is reacted with fatty acids, and the heterocyclic ring is further substituted with a linear or branched alkyl or alkenyl group having at least 10 carbon atoms; (ii) an organic anionic sulphonate selected from the group consisting of cumene sulphonate, xylene sulphonate, and toluene sulphonate, in their acid or salt form, and mixtures thereof.
