Patent

CA 2329959

The invention provides stable compositions comprising ester-containing quaternary ammonium material and one or more stabilising agent(s) chosen from: a) urea, b) urea derivatives, c) organic compounds with at least one free lone pair of electrons chosen from: i) primary amines, ii) secondary amines, and/or iii) tertiary amines, iv) glycerol wherein the composition is a liquid, molten or semi-solid containing % or less water, and when glycerol is used the ammonium material has 2 or less CH3 groups attached to the quaternary nitrogen atom.

L'invention porte sur des compositions stables comportant un composé d'ammonium quaternaire contenant des esters et un ou plusieurs agents stabilisateurs choisis parmi: (a) l'urée; (b) des dérivés de l'urée; (c) des composés organiques à au moins une paire d'électrons libre isolés choisis parmi (i) des amines primaires, (ii) des amines secondaires, et/ou (iii) des amines tertiaires, et (iv) du glycérol. Lesdites compositions se présentent sous forme de liquides à l'état fondu ou semi-solide contenant 10 % d'eau ou moins, et lorsqu'on utilise du glycérol, le composé d'ammonium comporte par exemple ou moins de deux groupes CH¿3? fixés à l'atome d'hydrogène quaternaire.
