ABSTRACT:
A uniform transparent aqueous liquid composition is disclosed. The solid components of the composition consist essentially of; (A) a nonionic surfactant having one or more polyoxyethylene radicals in the molecule as a hydrophilic group, (B) a nonionic water soluble polymer having hydroxyl radicals or pyrrolidone radicals in the molecule, and (C) as a fluorescent optical brightener, a 4,4'-bis(2-sulfostyryl)biphenyl salt. The composition is especially effective on clothes made of hydrophobic fibers, such as polyester fibers.
