Title (EN) MICROBICIDAL COMPOSITION CONTAINING A CELLULOSE ETHER
(FR) COMPOSITION MICROBICIDE CONTENANT UN ETHER DE CELLULOSE
Abstract:
(EN) An aqueous microbicidal composition of a pH below 6 contains a long-chain alkyl ester of general formula (I), wherein RI, RII? and R?III are hydrogen or lower alkyl groups, RIV is a long-chain alkyl group with 10-18 carbon atoms, RV is hydrogen or a group of formula (II) RVI N+ H3, wherein RVI is an alkylene group with 3-4 carbon atoms, A is a monovalent counter-ion, and n is the number of cationic groups in the ester compound, and a nonionic aqueous cellulose ether. The microbicidal composition has a prolonged microbicidal effect and an improved viscosity at elevated temperature. The microbicidal effect and the improved viscosity are lost when the pH value is raised. Preferably, the cellulose ether is an ethyl hydroxyethyl cellulose having a cloud point of 30-35 °C and a viscosity of 30-400 cP in a 1 % water solution, as measured according to Brookfield LV, 12 rpm at 20 °C.
(FR) Une composition microbicide aqueuse d'un pH inférieur à 6 contient un ester d'alkyle à chaîne longue de la formule générale (I), dans laquelle RI, RII et RIII représentent hydrogène ou des groupes alkyle inférieurs, RIV représente un groupe alkyle à chaîne longue contenant 10 à 18 atomes de carbone, RIV représente hydrogène ou un groupe de la formule (II) RVI N+ H3, dans laquelle RVI représente un groupe alkylène contenant 3 à 4 atomes de carbone, A représente un contre-ion monovalent, et n représente le nombre de groupes cationiques se trouvant dans le composé d'ester, ainsi qu'un éther de cellulose aqueux non ionique. La composition microbicide présente un effet microbicide prolongé, ainsi qu'une viscosité améliorée à température élevée. L'effet microbicide et la viscosité améliorée sont perdus lorsque la valeur du pH est élevée. L'éther de cellulose est, de préférence, une cellulose d'hydroxyéthyle éthylique ayant une température critique de solution comprise entre 30 et 35 °C, ainsi qu'une viscosité comprise entre 30 et 400 cB dans une solution à 1 % d'eau, mesuré selon Brookfield LV, 12 tours par minute à 20 °C.
