Abstract: The invention relates to a detergent composition comprising a bleach-sensitive component and a hydrogen peroxide source, wherein the hydrogen peroxide source is present in a particulate component having an average particle size, by weight, of from 700 microns to 1100 microns, preferably from 750 microns to 1000 microns, whereby at least 80 % by weight of the particulate component comprising the hydrogen peroxide source has a particle size of between 70 % to 130 % of the average particle size.

Description: Bleach-Containing Detergent Composition Field of the Invention The invention relates to detergent compositions comprising bleach sensitive ingredients and a hydrogen peroxide source of a specific particle size. Background to the Invention Bleach-containing detergent compositions generally contain an oxygen-based bleach, typically a perborate or percarbonate salts which releases hydrogen peroxide in the wash water, and often a bleach activator or precursor. In solid detergent compositions, these compounds are typically admixed as separate granules to the base composition. Detergents also contain certain ingredients which are bleach-sensitive and which can react with the bleaching agent during manufacturing or storage or in use. Thus, these bleach-sensitive ingredients may loose some of their performance when present in bleach-containing compositions. For example perfumes, enzymes, dyes and brighteners can react with bleaching agent, in particular percarbonate and perborate bleach and in particular when they are present as spray-on component or as admixed component. Various techniques are known to protect the bleach-sensitive ingredients, for example coating of these ingredients. However, there is still a need to further improve the stability of bleach-sensitive ingredients. The inventors have now found that this problem can be reduced when particulate hydrogen peroxide sources of a specific, larger particle size and having a narrow particle size distribution are incorporated in the solid detergent compositions. It is believed that this is due to the fact that the larger particle size hydrogen peroxide sources have a smaller surface area per weight unit and thus per active oxygen or available oxygen. There is thus a smaller total surface area per amount of active oxygen bleach in the composition, which may be in contact with the bleach-sensitive ingredients. Thus, there is a reduced possibility that the bleach-sensitive ingredients and the percarbonate or perborate are in contact and react together. In particular in compositions whereby bleach-sensitive ingredients are present as admixed granules, or even more in compositions whereby the bleach-sensitive ingredients are sprayed onto the detergent particles, including the percarbonate, it has been found beneficial for the stability ofthe bleach-sensitive ingredients, that the hydrogen peroxide source has the larger particle size ofthe invention. It is known that in general the larger the particle size of a particle, the slower the particle dissolves in water. Thus, this would also be expected for particulate hydrogen peroxide sources dissolve slower in water. However, the inventors have surprisingly found that the larger particle size hydrogen peroxide sources ofthe invention, in particular percarbonate salts, have a water-solubility which is comparable to the water-solubility of smaller sources, such as for example percarbonate salts having an average particle size of around 600 or even 500 microns. Also, the inventors have surprisingly found that the bleaching performance of detergent compositions incorporating a hydrogen peroxide source and a bleach activator is not always satisfactory after storage, even when the bleach is stable. Also they have found that the bleaching performance may differ from one batch of product to another. They have now found that this can be due to the segregation ofthe hydrogen peroxide source component in, particularly, the granular product, during manufacturing or during storage, resulting in an uneven distribution ofthe hydrogen peroxide source component and/or bleach activator component. The inventors have found that it can be advantageous that the a bleach activator component, or part thereof, also has an large average particle size, preferably similar to the particle size ofthe hydrogen peroxide source component, to reduce the segregation of theses components in the product. Preferably, the base granules ofthe composition also have an average particle size similar to the particle size ofthe hydrogen peroxide source component and preferably the bleach activator component. Summary of the Invention The invention provides a solid composition comprising a bleach-sensitive component and a hydrogen peroxide source wherein the hydrogen peroxide source is present in a particulate component having an average particle size, by weight, of from 700 microns to 1100 microns, preferably from 700 microns to 1000 microns, whereby at least 80% by weight ofthe particulate component comprising the hydrogen peroxide source has a particle size of between 60% to 140% ofthe ofthe average particle size. Preferably, the composition comprises one or more bleach activators. Detailed Description ofthe Invention Hydrogen Peroxide Source.

Thus, it may be preferred that the composition comprises at least two separate particles which comprise either anionic surfactant or aluminosilicate. 'Intimate mixture' means for the puφose ofthe invention that the two or more ingredients the component are substantially homogeneously divided in the component or particle. Namely, it has been found that the solubility and/ or dispensing ofthe composition is thereby improved.

Typically, the level of water in intimate mixture with the effervescence component is below 5% by weight of the total granule, preferably below 3%> and more preferably below 1.5%, preferably obtainable by dry-powder compaction or pressure agglomeration. These preferred dry effervescent particles result in a very fast carbon dioxide production and therefore in accelerated dispersibility and dissolution rate of the granular composition.

However, the choice of carbonate or bicarbonate or mixtures thereof in the dry effervescent granules may be made depending on the pH desired in the aqueous medium wherein the dry effervescent granules are dissolved. For example where a relative high pH is desired in the aqueous medium (e.g., above pH 9.5) it may be preferred to use carbonate alone or to use a combination of carbonate and bicarbonate wherein the level of carbonate is higher than the level of bicarbonate, typically in a weight ratio of carbonate to bicarbonate from 0J to 10, more preferably from 1 to 5 and most preferably from 1 to 2.

Additional classes of SRA's include: (I) nonionic tejephthalates using diisocyanate coupling agents to link polymeric ester structures, see U.S. 4,201,824, Violland et al. and U.S. 4,240,918 Lagasse et al.; and (II) SRA's with carboxylate terminal groups made by adding trimellitic anhydride to known SRA's to convert terminal hydroxyl groups to trimellitate esters. With the proper selection of catalyst, the trimellitic anhydride forms linkages to the terminals ofthe polymer through an ester ofthe isolated carboxylic acid of trimellitic anhydride rather than by opening ofthe anhydride linkage. Either nonionic or anionic SRA's may be used as starting materials as long as they have hydroxyl terminal groups which may be esterified. See U.S. 4,525,524 Tung et al.. Other classes include: (III) anionic terephthalate-based SRA's of the urethane-linked variety, see U.S. 4,201,824, Violland et al.; Other Optional Ingredients Other optional ingredients suitable for inclusion in the compositions ofthe invention include colours and filler salts, with sodium sulfate being a preferred filler salt.

The compositions in accord with the present invention can also be used in or in combination with bleach additive compositions, for example comprising chlorine bleach. Chlorine-Based Bleach The detergent compositions can include as an additional component a chlorine-based bleach. However, since the detergent compositions ofthe invention are solid, most liquid chlorine-based bleaching will not be suitable for these detergent compositions and only granular or powder chlorine-based bleaches will be suitable.

The chlorine-based bleachis such that a hypochlorite species is formed in aqueous solution. The hypochlorite ion is chemically represented by the formula OCT. Those bleaching agents which yield a hypochlorite species in aqueous solution include alkali metal and alkaline earth metal hypochlorites, hypochlorite addition products, chloramines, chlorimines, chloramides, and chlorimides.
