Abstract

The detergent additive granulate is a cogranulate containing at least one enzyme and at least one photobleaching agent. If a detergent, a component of which is such detergent additive granulate, is used for laundering, the photobleaching agent will not tend to adhere selectively to the laundry during the initial washing process.

Description

DETERGENT ADDITIVE GRANULATE AND DETERGENT
The concept of incorporation of a photobleaching agent in a detergent is known, reference being made to e.g. DE 3430773, EP 119746, and EP 87833. The photobleaching agent is inactive if not exposed to UV light, and thus, under normal conditions, the photobleaching agent will first be activated and function as a bleaching agent when the clean laundry is dried in the open. This is a clear advantage over the detergents with a normal bleach, which will function as a bleaching agent already in the washing solution and thus damage sensitive detergent additives, especially enzymes. The introduction of photobleaching agents in detergents in solid form is not without problems, though. During the intial stages of the washing process, when the solid detergent agent is introduced into the washing float, particles of pure photobleaching agent or particles of detergent additives, which contains photobleaching agents at the surface thereof, will tend to adhere to the laundry due to a selective adhesion ability of the photobleaching agent to the laundry, and also such photobleaching agent will tend to stay with the laundry without being dissolved during the washing process. Most photobleaching agents possess a very intense color, and such photobleaching agents will create a most undesirable staining of the laundry. In case the photobleaching agent is colorless, the above indicated attachment thereof to the laundry during the washing process will create an uneven concentration of photobleaching agent on the laundry, and in that case an uneven overbleaching action will take place when the laundry is dried in the open.
Thus, there is a need for a detergent additive in solid form comprising a photobleaching agent, whereby during the initial washing process the photobleaching agent will not tend to adhere selectively to the laundry.
Now, according to the invention it has been found that a detergent additive granulate of a special composition will fulfil the above objective.
Thus, the detergent additive granulate according to the invention is a co-granulate containing at least one enzyme and at least one photobleaching agent. The photobleaching agent can be any photobleaching agent, e.g. Tinolux BBS, vide the following examples, zinc phthalocyanine sulfonate (ZPS), and aluminum phthalocyanine sulfonate (APS).
The detergent additive granulate according to the invention will fulfil the above objective in an especially advantageous manner, if produced by means of a drum granulator, as will later be described in more detail.
The detergent additive granulate can and will usually contain other components besides the components listed above, provided that these components do not damage the enzyme and/or the photobleaching agent. In GB 2.179.053 an aqueous fabric washing detergent is described, which can contain both enzymes and a photobleaching agent. However, this detergent is aqueous, and the above problem, which is solved according to the invention, does not appear at all in relation to aqueous detergents, which exhibit other problems, e.g. stability problems. EP 119.746 describes a detergent powder which contains both photobleach and enzyme. The first step during the production of this washing powder is the formation of the aqueous crutcher slurry, consisting of surfactants, builders, fillers, and a solution of the photobleach. This crutcher slurry is spraydried, whereby the so-called base powder is formed. The enzyme which may optionally be added fvide page 4, line 29 in EP 119.746) has to be added as enzyme containing particles separate from the base powder, due to the fact that the enzyme activity in the base powder would be reduced severely or lost completely, if the enzyme was added to the crutcher solution. Thus, the EP 119.746 contains enzyme free, photobleaching agent containing particles and photobleaching agent free enzyme containing particles. It has been found that the problem of staining and overbleaching is not completely solved in relation to this prior art washing powder.
DE 28 13 198 describes a bleaching agent which contains a special photoactivator. This bleaching agent is produced by cogranulation of all constituents of the bleaching agent to a cogranulate or by granulation of a single constituent on a basis detergent component, whereas according to the invention two sensitive constituents of the detergent are selected, i.e. the enzyme and the photobleaching agent, and cogranulated. The detergent additive granulate according to the invention can be produced by co-granulation in many ways, e.g. as indicated in the following.
I. A co-granulate of the so-called T-granulate type, as described in US
4,106,991 (Novo Nordisk A/S, Denmark), i.e. with cellulose fibres.
II. A co-granulate corresponding to US 4,661,452 (Novo Nordisk A/S, Denmark).
III. A co-granulate of the core type, as described in DK 4368/88. In this case it is specially preferred that the photobleaching agent is part of the core and that the enzyme is part of the coating.
IV. A co-granulate of the type described in DK 4369/88. In this case the photobleaching agent is added with the concentrated enzyme solution.
V. A co-granulate of the so-called "Marumerizer" type, as described in GB 1,362,365.
VI. A co-granulate of the prill type.
VII. A co-granulate of the Sparks type, as described in WO 85/05288.
VIII. A co-granulate of the fluid bed type.
In all cases the photobleaching agent is added as an aqueous solution, preferably as part of the granulation water.
In a preferred embodiment of the detergent additive granulate according to the invention the co-granulate is coated. In this manner the object of the invention is fulfilled to a very high extent. The usual coating agents may be used, e.g. the coating agents described in DK 0121/88, DK 1377/88, and DK 1378/88.
In a preferred embodiment of the detergent additive granulate according to the invention the enzyme is one or more of the enzymes protease, amylase, lipase, cellulase, oxidase, and amidase. These are the most common enzymes used in the detergent additive.
In a preferred embodiment of the detergent additive granulate according to the invention between 2 and 40% w/w of cellulose fibres are incorporated into the granulate. A granulate of this kind can be produced according to US
4,106,991 (Novo Nordisk A/S, Denmark). In this manner a dust free granulate is obtained which can easily be produced in an industrial scale.
Also, the invention comprises a detergent which contains the detergent additive granulate according to the invention. In a preferred embodiment of the detergent according to the invention the concentration of the detergent additive is between 0.05 and 5% w/w. In this manner the object of the invention is fulfilled, and also, the photobleaching effect is fully satisfactory.
In the following the production of the detergent additive granulate is illustrated in Examples 1 - 11, and the use of the detergent addit e granulate is illustrated in Example 12.

Finally the product is dried in a fludized bed drier.
The product is directly usable or it may be coated with a protective coating as described in example 22 of US 4,106,991 (Novo Nordisk A/S, Denmark) or in WO 89/08694 (Novo Nordisk A/S, Denmark) or in WO 89/08695 (Novo Nordisk A/S, Denmark).
Depending on formulation and extruder type products with particle shapes ranging from pure spheres to short rod like shapes can be produced. Methods for production of spheronized/marumerized products are described in GB 1,362,365 (Novo Nordisk A/S, Denmark) and US 4,661,452 (Novo Nordisk A/S, Denmark).
EXAMPLE 12
This example is a spotting example illustrating the use of the detergent additive granulate according to the invention.
