Amine fabric softener actives are prepared in dispersion and/or clear form with materials to improve performance by increasing the cationic charge density. These materials include polycationic compounds, especially cationic polymers; single long-chain cationic compounds; and carboxylic acids that increase the acidity in the rinse, thus lowering pH and increasing the percentage of amine fabric softener active that is protonated. Antistatic properties are also improved.
Selon l'invention, on prépare des agents actifs adoucissants pour le linge et à base d'amines, dans une dispersion et/ou sous forme claire, à l'aide de matières destinées à améliorer les performances adoucissantes par accroissement de la densité de charge cationique. Ces matières comprennent des composés polycationiques, notamment des polymères cationiques; des composés cationiques simples à longue chaîne, ainsi que des acides carboxyliques accroissant l'acidité lors du rinçage et donc abaissant le pH et augmentant le pourcentage d'agents adoucissants actifs à base d'amines obtenus par protonation. La composition de l'invention possède également des propriétés antistatiques améliorées.
