Abstract
A method for increasing the standard viscosity (SV) of an emulsion, and the composition of the emulsion resulting thereby is provided. Also, an alternative method for increasing the standard viscosity as well as increasing the shelf life, i.e., SV stability, of quaternary mannich microemulsion is provided.
