A fabric care composition contains a fabric softening active and a carrier. The fabric softening active may contain a mixture of quaternary nitrogen compounds of general formula (II) where each R1 is independently selected from the group consisting of ethyl, propyl, isopropyl, or butyl; each R2 is independently selected from the group consisting of a saturated C1-22 alkyl group, or an unsaturated C1-22 alkyl group; each R3 is independently selected from the group consisting of a saturated C1-22 alkyl group, or an unsaturated C1-22 alkyl group; each n is independently from about 1 to about 25; m is from 0 to 4; o is from 0 to 4; m + o = 4; and X- is an anion. The mixture of quaternary nitrogen compounds contains at least about 5 % mono-ester quaternary nitrogen compound with m = 1 and o = 3, at least about 15 % di- ester quaternary nitrogen compound with m = 2 an o = 2, and at least about 5 % tri-ester quaternary nitrogen compound with m = 3 and o = 1. Also, a novel quaternary nitrogen compound has the above formula, where m = 4 and o = 0. Novel processes may be used to make these quaternary nitrogen compounds.
L'invention concerne une composition adoucissante pour tissu renfermant un agent d'adoucissage actif et un vecteur. L'agent peut contenir un mélange de composés d'hydrogène quaternaire de formule (II). Dans ladite formule, chaque R¿1? peut être indépendamment éthyle, propyle, isopropyle, ou butyle; chaque R¿2 ?peut être indépendamment un groupe alkyle C¿1-22? saturé ou insaturé; chaque R¿3? peut être indépendamment un groupe alkyle C¿1-22? saturé ou insaturé; chaque n peut valoir indépendamment entre environ 1 et environ 25; m vaut de 0 à 4; o vaut de 0 à 4; m + o = 4; et X?-¿ est un anion. Le mélange des composés considérés renferme au moins environ 5 % de composé d'hydrogène quaternaire monoester, avec m = 1 et o = 3, au moins environ 15 % de composé d'hydrogène quaternaire diester, avec m = 2 et o = 2, et au moins environ 5 % de composé d'hydrogène quaternaire triester, avec m = 3 et o = 1. L'invention concerne en outre un composé d'hydrogène quaternaire représenté par la formule ci-dessus, avec m = 4 et o = 0. L'invention concerne enfin des procédés relatifs à l'élaboration de ce type de composé.
