Description

"Kit with performance-enhancing effect"

The invention relates to a kit with a metering device which comprises a hollow body having a cavity formed by a wall or a plurality of walls for receiving a power-enhancing compound. The invention also relates to the use of a metering device and a method for washing and / or conditioning laundry using the kit.

In the effort to achieve energy-saving washing and bleaching processes, in addition, application temperatures still gain significantly less than 60 ° C., especially below 45 ° C., down to the cold water temperature in recent years.

At these low temperatures, the effect of the previously known activator compounds usually decreases noticeably. There was therefore no lack of ambition for this

Temperature range to develop more effective activators. Therefore, the use of transition metal compounds, in particular transition metal complexes, to increase the oxidation power of peroxygen compounds or atmospheric oxygen in washing or

Detergents have been proposed.

The use of such transition metal catalysts has been hitherto made difficult in practice by the requirement to incorporate the bleach as well as the catalyst storage stable in a means. The storage stability must be ensured both in the chemical sense, that is neither

Bleach still complex may decompose during storage or degrade the other ingredients of the funds, as well as in the physical sense, that means the agent may not be separated, so that, for example, a component on the bottom or top of the packaging container enriches and at the time of removal only a part of the total means from the container of this part not the

Total composition of the agent corresponds. In addition, separation of the components can adversely affect the aesthetics of a product.

The chemical stability can be improved, for example, by enveloping the particles. For example, the physical stability problem can be circumvented by providing the user with pre-portioned quantities of the agent for use. If you apply the entire portion at once, it does not matter if this portion is a homogeneous or heterogeneous particle mixture. Both portions in bags made of water-soluble material and tear-open bags made of water-insoluble material are conceivable. However, this solution is disadvantageous because of the additional packaging costs and the associated costs. However, the stability problems identified for bleach activators in the form of transition metal complexes also occur in other performance enhancing ingredients of waxes and cleaners, such as enzymes.

It is therefore an object of the present invention to improve the washing or conditioning process of fabrics with respect to the washing and conditioning performance in a manner that is easy for the user to handle.

This object is achieved by a kit comprising a metering device and a fixed one

A release system, wherein the metering device comprises a hollow body having a cavity formed by a wall or a plurality of walls for receiving the release system, the release system containing a carrier system and a power enhancing compound and wherein the release of the power enhancing compound more than one

Application cycle takes place.

In one embodiment, the metering device has a closable opening for filling the cavity.

In this embodiment, after the release system has been consumed, the application may replace it with a new delivery system and need not replace the entire kit.

It is preferred that the performance enhancing compound is selected from the group of bleach boosters, enzymes, enzyme boosters, optical brighteners, shading dyes, soil release polymers, grayness inhibitors, silicones, microcapsules, and mixtures thereof.

These performance enhancing compounds provide desirable improvements in terms of primary and / or secondary detergency performance of a laundry and / or conditioner, and often can not be stably incorporated into a laundry and / or conditioner.

It is preferred that the amount of power-enhancing compound is between 1 and 60% by weight, preferably between 2 and 50% by weight and more preferably between 5 and 40% by weight, based in each case on the release system.

It is particularly preferred that the power enhancing compound is a bleach enhancer in the form of a transition metal complex. Preferred transition metal complexes include salen-type or terpyridine-type ligands and a central atom selected from the group consisting of Mn, Fe, Co, Ni, V, Ru, Ti, Mo, W, Cu and / or Cr. Especially with regard to the ever-decreasing washing temperatures, the use of bleach-enhancing compounds as a power-enhancing compound is particularly advantageous.

It is preferred that the support material is selected from the group consisting of inorganic alkali metal salts, organic alkali metal salts, inorganic

Alkaline earth metal salts, organic alkaline earth metal salts, carbohydrates, silicates, layered silicates, bentonites, zeolites, urea, polyalkylene glycols, polyvinyl alcohol, acrylic polymers, polyamides, polyurethanes, surfactants, soaps, fatty acids and mixtures thereof.

It is preferred that the amount of support material is between 40 and 99 wt .-%, preferably between 50 and 98 wt .-% and particularly preferably between 60 and 95 wt .-% in each case based on the release system.

These carrier materials are odorless and / or inexpensive. Moreover, they are all inert for power enhancing connections.

It is further preferred that at least 80% by weight of the release system has a dissolution kinetics in the range of 0.00001 gl_ ^" min ^{" 1} to 0.1 gl_ ^" min ^{" 1} and more preferably in the range of 0.0002 gl_ ^" min ^{" 1} to 0.01 gL ^" min ^" .

Such a dissolution characteristic ensures that the solid release system the

power-enhancing connection across multiple applications, not just one

Application cycle releases.

In a particularly preferred embodiment, the hollow body is made of a material which comprises a thermoplastic polymer and biocidal metals and / or metal ions.

By using a biocidal material in the material for making the metering device, the kit has a further functionality. Due to the often low

Washing temperatures are not always all germs or fungi, such as the

human pathogenic Candida albicans, killed. The use of biocidal metals and / or metal ions reduces the colonization and / or multiplication of microorganisms on launded fabrics and / or in the washing machine or even suppresses them for a longer time. The invention also relates to the use of a kit comprising a metering device and a solid release system, the metering device comprising a hollow body having a cavity formed by a wall or a plurality of walls for receiving the release system, and wherein the release system comprises a carrier system and a power enhancing compound to enhance the washing and / or conditioning performance of washing and / or conditioning agents in the washing and / or conditioning of textile fabrics.

Diameter of 2.5 cm in a spherical hollow body made of HDPE with a diameter of 8 cm. The hollow body had 6 perforations with a diameter of 1.5 mm each.

The dosing device, together with 3.5 kg of textiles, was placed in a 6 kg drum of a washing machine (Miele W 918). The detergent used was 67.5 g of a heavy-duty universal detergent containing approximately 12 g of percarbonate per wash.

The wash result was compared to an analog wash load which was washed with only 67.5 g of the solid universal detergent.

In the washing tests, the washing machine was loaded with 3.5 kg of textiles, test fabrics (WFK 10 A, WFK 20 A and WFK 30 A) and 4 SBL 2004 wipes each with standardized dirt load (32 g dirt ballast). The washes were carried out at 40 ° C and then after hanging drying and mangling of the laundry their whiteness (remission value Y) was determined spectrophotometrically (see Table 1). The determination took place at 420 nm (device:

Datacolor Spectraflash 600, 30 mm aperture).
