Furthermore, the present invention relates to the use of said substantially linear nonionic surfactant in a fabric bleaching composition comprising a bleach to treat a fabric whereby stain removal and/or bleaching benefits are provided.

Bleaching composition comprising substantially linear nonionic surfactants

A process of treating fabrics comprises the steps of forming an aqueous bath comprising water, dissolving or dispersing a conventional laundry detergent therein, adding a liquid composition comprising a peroxygen bleach, a builder and a modified polycarboxylate co-builder and subsequently contacting said fabrics with said aqueous bath. Furthermore, the use of a builder and a modified polycarboxylate co-builder in a laundry additive comprising a peroxygen bleach to treat fabrics, whereby stain removal and/or bleaching benefits are provided, is also claimed.
