A process for producing pulverulent or granular detergent mixtures

Powdered or granular detergent mixtures with good cold-water dispersibility are obtained by drying and solidifying, in the prior art manner, mixtures containing: a) quaternary di-fatty acid trialkanol amine ester salts of formula (I) in which R CO is an aliphatic acyl residue with 12 to 22 carbon atoms and 0, 1, 2, or 3 double bonds, n is 2 or 3 and X is halogenated hydrocarbon, methosulphate or methophosphate; and b) hydroxy compounds selected from the group consisting of fatty alcohol polyglycol ethers, polyol fatty acid partial esters and carbohydrates. The products are suitable for the production of laundry revivers and softeners and hair care products.
