US 12,441,957 B2 · Detergent composition for fibers

Abstract

The present invention is a detergent composition for fibers that contains components (a) and (b) described below and satisfies at least one requirement of the following: requirement (1) a proportion of a content of component (a) to a total content of components (a) and (b1) is 35 mass % or more and 80 mass % or less; and requirement (2) a proportion of the content of component (a) to a total content of components (a) and (b2) is 50 mass % or more and 80 mass % or less. Component (a) is a sulfosuccinic acid ester or a salt thereof having a branched hydrocarbon group with 5 or more and 18 or less carbons, and component (b) is one or more surfactants selected from the following components (b1) and (b2): component (b1) an anionic surfactant (excluding component (a)); and component (b2) one or more nonionic surfactants selected from an aliphatic alcohol alkoxylate and an ester alkoxylate.
