terms for current commercial preparations, typical amounts are up to 5 mg by weight, more typically 0.01 mg to 3 mg, of active enzyme per gram of the detergent composition. Stated otherwise, the compositions herein will typically comprise from 0.001 % to 5%, preferably 0.01 %-1 % by weight of a commercial enzyme preparation. In the particu- lar cases where activity of the enzyme preparation can be defined otherwise such as with cellulases, corresponding activity units are preferred (e.g. CEVU or cellulase Equiva› lent Viscosity Units). For instance, the compositions of the present invention can contain cellulase enzymes at a level equivalent to an activity from 0.5 to 1000 CEVU/gram of composition. Cellulase enzyme preparations used for the purpose of formulating the compositions of this invention typically have an activity comprised between 1,000 and 10,000 CEVU/gram in liquid form, around 1,000 CEVU/ gram in solid form. 

Other Optional Ingredients 

The present invention can include optional components conventionally used in textile treatment compositions, for example: brighteners, colorants; surfactants; anti-shrinkage agents; fabric crisping agents; spotting agents; germicides; fungicides; anti-oxidants such as butylated hydroxy toluene, anti-corrosion agents, antifoam agents, and the like. 

The present invention can also include other compatible ingredients, including those as disclosed in WO96/02625, WO96/21714, and WO96/21715, and dispersible polyolefin such as Velustrolfi as disclosed in co-pending application PCT/US 97/01644, and the like. The present invention can also contain optional chelating agents. 

The benefit provided by the use of the present invention is that the polyamino functional polymer containing com› position is stabilised by means of the CGI. Accordingly, in an aspect of the invention, there is provided the use of a crystal growth inhibitor to stabilise compositions compris› ing amino-functional polymer. 

As a consequence, the compositions of the invention provide better care to the fabrics compared to compositions which do not have such stabilisation means. Accordingly, in another aspect of the invention, there is provided a method for providing care to the color fabrics which comprises the steps of contacting the fabrics with a composition of the invention. 

The color care benefit may either be assessed visually or by determination of the so-called delta-E values. 

When the visual assessment is used, a panel of expert graders visually compare, according to the established panel score unit (PSU) scales, fabrics treated with and without the composition according to the present invention. A positive PSU value indicates a better performance (PSU scale: 0=no difference, 1=1 think there is a difference, 2=1 know there is a difference, 3=1 know there is a lot of difference, 4=1 know there is a whole lot of difference). 

Another method for the assessment of the color care benefit to fabrics is the determination of the so-called delta-E values. Delta E’s are defined, for instance, inASTM D2244. Delta E is the computed color difference as defined in ASTM D2244, i.e. the magnitude and direction of the difference between two psychophysical color stimuli defined by tristimulus values, or by chromaticity coordinates and luminance factor, as computed by means of a specified set of color-difference equations defined in the CIE 1976 CIELAB opponent-color space, the Hunter opponent-color space, the Friele-Mac Adam-Chickering color space or any equivalent color space. 

Applications 

The compositions of the invention are suitable for use in any steps of the domestic treatment, that is as a pretreatment 

composition, as a wash additive as a composition suitable for use in the rinse-cycle of the laundry cycle or applied on a dryer-sheet. Obviously, for the purpose of the invention, multiple applications can be made such as treating the fabric with a pre-treatment composition of the invention and also thereafter with a composition of the invention suitable for use in the rinse cycle and/or suitable for use as a dryer-sheet. The compositions of the invention may also be in a spray, foam, or aerosol form which for example can be suitable for use while ironing, or applied on the surfaces of the tumble dryer. 

The invention is illustrated in the following non limiting examples, in which all percentages are on an active weight basis unless otherwise stated. 

In the examples, the abbreviated component identifica› tions have the following meanings:
