Abstract: The present invention relates to a composition capable of improving properties of cleaning a dirt during cleaning.
The composition of the present invention is a composition containing a modified hydroxyalkyl cellulose (A) and a cationic surfactant (B), wherein the modified hydroxyalkyl cellulose (A) has a cationic group and a hydrophobic group represented by a formula (1), each of which is bound to a group resulting from eliminating a hydrogen atom from a hydroxy group of the hydroxyalkyl cellulose; a degree of substitution of the hydroxyalkyl group in the hydroxyalkyl cellulose is 0.1 or more and 3 or less; and a content of the cationic surfactant (B) is more than 1 part by mass and 1,500 parts by mass or less relative to 1 part by mass of the modified hydroxyalkyl cellulose (A). *—Z—R1 (1)-

Abstract: The present invention relates to (1) a process for producing a hydroxyalkyl cellulose having an excellent water-solubility while maintaining a high reaction selectivity by adding a basic compound and an alkyleneoxide to a cellulose to conduct a reaction therebetween in which the basic compound is added in a total amount of from 0.3 to 1.5 mol per 1 mol of an anhydroglucose unit in the cellulose, and the alkyleneoxide is added in a total amount of from 1.0 to 3.0 mol per 1 mol of an anhydroglucose unit in the cellulose, the process including a step of adding the basic compound in an amount of from 50 to 95% of the total amount of the basic compound to be added during the process, and then adding the alkyleneoxide in an amount of from 30 to 80% of the total amount of the alkyleneoxide to be added during the process to react the compounds with the cellulose, thereby obtaining a reaction mixture; and a step of adding a remaining amount of the basic compound and a remaining amount of the alkyleneoxide to the reaction mixture obtained in the previous step to conduct a reaction therebetween; (2) a hydroxyalkyl cellulose produced by the process; and (3) a process for producing a cationized hydroxyalkyl cellulose using the resulting hydroxyalkyl cellulose.
