Detergents which, in addition to inorganic and/or organic peracids, contain specific stilbene compounds as fluorescent whitening agents. These detergents are stable for several months and already show the customary cleaning properties at washing temperatures of 20.degree.-60.degree. C.

Stable bleaching detergents containing stilbene fluorescent whitening

Storage-stable anionic liquid detergent compositions containing fluorescent whitening agents of the class of the amphoteric distyryls. These detergent compositions cause no bleach spots when they come in contact with textile fabric.

Storage-stable anionic liquid detergent compositions containing

Liquid detergent compositions which are stable on storage and contain fluorescent whitening agents from the class of the disulfonated distyrylbiphenyl and distyrylphenyl compounds; they do not produce bleach spots on direct contact with textile fabric. Some of the fluorescent whitening agents used are novel.

Liquid detergent compositions containing disulfonated fluorescent

Mixtures of fuorescent whitening agents comprising 5 to 45 parts by weight of 4,4'-bis(cyanovinyl)stilbene and 95 to 55 parts by weight of a compound of formula ##STR1## and the use of said mixtures and compositions containing them for whitening polyester fibres and textile material containing polyester fibres.

Mixtures of fluorescent whitening agents

A process for increasing the degree of whitness of polyester-containing textile material by the combined application of a fluorescent whitening agent and, as booster, a compound which fluoresces in the absorption range of said fluorescent whitening agent, and a composition for whitening polyester-containing textile material.
