Methods of using esterquats having acyl groups derived from short-chain monocarboxylic acids and short-chain dicarboxylic acids to improve cosmetic compositions
   
   

Methods of improving the stability of a composition containing a long-chain esterquat and methods of improving the microbicidal properties of a cosmetic composition are described wherein a short-chain esterquat having acyl groups derived from a mixture of at least one monocarboxylic acid having from 6 to 10 carbon atoms, and at least one dicarboxylic acid having from 2 to 12 carbon atoms is combined with a cosmetic composition.
