The present invention relates to fabric softening compositions of insoluble, degradable cationic fabric softeners at high concentrations. In particular, the present invention addresses the problem of dispersability which is usually associated with concentrations of biodegradable cationic fabric softeners above 30 %. Including a mixture of aromatic acids, especially benzoic acid and salicylic acid, at an amount of at least 10 % in total, has proven to eliminate the dispersability drawbacks and stabilize the high concentration of the fabric softener active.
Compositions d'adoucissant textile contenant de fortes concentrations d'adoucissants textiles cationiques, dégradables et insolubles. Cette invention concerne plus particulièrement le problème dela dispersibilité qui est habituellement associé aux concentrations d'adoucissant textiles cationiques biodégradables supérieures à 30 %. Le fait d'ajouter un mélange d'acides aromatiques, notamment d'acide benzoïque et d'acide salicylique suivant une quantité supérieure ou égale à 10 % au total a eu pour effet d'éliminer les problèmes de dispersibilité et de stabiliser la forte concentration de l'agent actif de l'adoucissant textile.
