Definitions

the present invention relates to the stabilization of hypochlorite-containing liquid detergents which contain optical brighteners.
Sodium hypochlorite is known to be a highly effective bleaching agent and has been used for a long time, optionally with soaps and / or synthetic surfactants, to remove stains and all sorts of soils from laundry to textiles as well as hard surface cleaning. It is normally sold in concentrations of about 2% to 10% by weight in water for household use
Liquid detergent formulations or corresponding preparations of hard surface cleaners containing hypochlorite as a bleach component are susceptible to loss of activity upon prolonged storage, especially because of the then-degradation of the hypochlorite.
ingredients that are desirable from an application point of view or for aesthetic reasons in detergents and cleaners include, in addition to the performance of such agents crucial influencing agents, among which in particular the hypochlorite may be mentioned, also active ingredients, which rather the visual appearance of the so affect treated textiles.
active ingredients which rather the visual appearance of the so affect treated textiles.
optical brighteners to name, which raise during the washing process on the fibers of the textile material. These compounds are able to absorb light and emit light of shorter wavelength.
the present invention is the use of cyclodextrin for stabilizing optical brighteners in aqueous liquid detergents containing alkali metal hypochlorite.
Cyclodextrins also called cycloglucans, are formed in the degradation of starch by Bacillus macerans or B. circulans under the action of cyclodextrin glycosyltransferase.
the cyclodextrins consist of ring-shaped ⁇ -l, 4-linked glucose units, usually from 6, 7 or 8 glucose units; these are referred to as ⁇ -, ß- or ⁇ -cyclodextrin.
the use of cyclodextrins or their derivatives as active cleaning component is described, for example, in International Patent Application WO 94/10280.
hypochlorite-containing liquid agents on addition of cyclodextrins to hypochlorite-containing liquid agents, the stability of optical brighteners contained in these agents is increased and also that the hypochlorite is degraded less rapidly on storage than is the case without this addition.
a second object of the invention is an aqueous liquid bleach or bleaching detergent containing alkali hypochlorite and optical brightener, which is characterized in that it additionally contains cyclodextrin.
the agent according to the invention may contain any cyclodextrins, for example ⁇ -, ⁇ - or ⁇ -cyclodextrin.
⁇ -cyclodextrin is preferred.

Optical brighteners are usually present only in small amounts, for example from 10 ppm to 0.5 wt .-%, in detergents or bleaches.
Preparations according to the invention are particularly suitable and very effective as bleaching agents or bleaching detergents for white textiles.
An agent of the present invention is effective against a variety of stains, including greasy soils such as sebum, makeup, or lipstick, enzymatically removable stains such as blood, grass or cocoa, and bleachable soils such as wine, coffee or tea, even after aging of the composition means if it has been stored for a long time after its production.
bleaches according to the present invention are suitable for bleaching textiles of various materials, including those of natural fibers such as cotton or linen, but also those of synthetic material, such as synthetic polymer fibers, and also of corresponding ones mixed fabrics.
a liquid composition according to the present invention is advantageously applied to the textiles to be cleaned in diluted form, for example when it is used in manual or machine washing of textiles as a washing additive or as a detergent alone, but it can additionally or alternatively also undiluted to the textile be applied, for example, as a liquid pretreatment agent or stain remover.
a bleaching agent in the form of hypochlorite is an essential component of the compositions according to the invention.
Bleaches per se are well-known components of detergent and cleaner compositions and, in particular, are also successful in controlling mildew and mildew and in disinfecting.
alkali metal hypochlorites such as potassium hypochlorite
