Abstract

Compositions are disclosed containing fabric softener compound having two hydrophobic groups attached to the remainder of the compound through ester linkages (DEQA), said compositions being concentrated and containing viscosity/dispersibility modifiers which are single long chain cationic surfactants, highly ethoxylated nonionic surfactants and/or mixtures thereof. Premixes of the DEQA and viscosity modifiers to lower the viscosity of the molten DEQA are disclosed. Processes for making aqueous liquid compositions from solid particulate compositions containing the DEQA are also disclosed.
