Abstract
This invention relates to a process for preparing an inverse emulsion comprising mixing an aqueous solution comprising a water-soluble (co)polymer A synthesized from at least one cationic monomer and an inverse EMI 2 emulsion comprising a water-soluble (co)polymer B synthesized from at least one cationic monomer, optionally followed by distillation.This invention also relates to the inverse emulsion thus obtained, a detergent or cosmetic or softening composition comprising such an inverse emulsion, as well as the use of such an inverse emulsion to improve the softening properties of a fabric softening composition.
