Abstract:
Solid esterquats with improved dispersibility in water are obtained by quaternizing fatty acid triethanolamine esters with alkylating agents in known manner in the presence of a) dispersants selected from the group consisting of fatty alcohols, fatty acid monoglycerides and dialkyl ethers and optionally b) emulsifiers selected from the group consisting of fatty alcohol polyglycol ethers, fatty acid monoglyceride polyglycol ethers, fatty acid oligoglyceride polyglycol ethers, polysorbates and alkyl oligoglucosides. The products are suitable, for example, for the production of hair-care preparations.
