Definitions

• detergent compositions It is a particular requirement of detergent compositions that they should deliver the detergent actives to the wash water as soon as possible on contact with water.
• detergent compositions have tended to have increased densities above 650g/l, or above 700g/l or even above 750g/l, or are even provided in the form of tablets. This has tended to inhibit dispensing and/or distribution and consequently rapid delivery of the detergent actives to the wash water.
• EP- A-466484 describes the use of disintegrants and their mechanisms. It is stated that
• Suitable polymers should be heat stable up to at least the temperature for the appropriate detergent processing.
• the disintegrants are generally present in the detergent composition in amounts from 1 to 20 wt%, preferably in amounst of 2 to 15 wt%, most preferably from 2 to 10 wt% based on the weight of the detergent composition. It may be particularly advantageous to use the water-swellable cationic polymer in combination with an additional disintegrant, such as any of those discussed in EP-A- 466484. In such cases, it may be preferred to from a pre-mix of the water-swellable cationic polymer and additional disintegrant prior to incorporation into a detergent composition.
• suitable phosphate-containing detergent builders include, but are not limited to, the alkali metal, ammonium and alkanolammonium salts of polyphosphates (exemplified by the tripolyphosphates, pyrophosphates, and glassy polymeric meta- phosphates).
• Preferred phosphate builders are tetrasodium pyrophosphate or more preferably anhydrous or partially hydrated sodium tripolyphosphate at levels of from 0.5% to 50%, more preferably from 5% to 45% by weight based on the detergent composition as a whole.
• polymeric or oligomeric polycarboxylates are present at levels of less than 5%, preferably less than 3% or even less than 2% or even 0% by weight of the compositions.
• Chelants are also useful as the polyanionic builder for use in the detergent compositions of the invention.
• chelant is meant sequester (chelate) metal ions.
• These components are generally present at a level of from 0.005% to 10%, preferably from 0.1% to 5%, more preferably from 0.25% to 7.5% and most preferably from 0.3% to 2% by weight of the compositions.
• the particulate material used for making the tablet of this invention can be made by any particulation or granulation process.
• An example of such a process is spray drying (in a co-current or counter current spray drying tower) which typically gives low bulk densities 600g/l or lower.
• Particulate materials of higher density can be prepared by granulation and densification in a high shear batch mixer/granulator or by a continuous granulation and densification process (e.g. using Lodige® CB and/or Lodige® KM mixers).
• Other suitable processes include fluid bed processes, compaction processes (e.g. roll compaction), extrusion, as well as any particulate material made by any chemical process like flocculation, crystallisation sentering, etc.
• Suitable coating materials are fatty acids, C2-C13 dicarboxylic acids, fatty alcohols, diols, esters and ethers.
• Preferred fatty acids are those having a carbon chain length of from C12 to C22 and most preferably from C18 to C22.
• a coating of any desired thickness can be applied according to the present invention.
• the coating forms from 1% to 10%, preferably from 1.5% to 5%, of the tablet or detergent component weight.
• composition or component thereof according to the present invention will contain additional detergent ingredients.
• additional detergent ingredients The precise nature of these additional ingredients, and levels of incorporation thereof will depend on the application of the component or compositions and the physical form of the components and the compositions.

• C10-C20 conventional soaps may also be used. If high sudsing is desired, the branched-chain C ⁇ Q-CI g soaps may be used. Mixtures of anionic and nonionic surfactants are especially useful.
• Suitable cationic surfactants for incorporation into the detergent composition of the invention include the quaternary ammonium surfactants.
• the quaternary ammonium surfactant is a mono C6-C16, preferably Cg-Cio N- alkyl or alkenyl ammonium surfactants wherein the remaining N positions are substituted by methyl, hydroxyethyl or hydroxypropyl groups.
• Preferred are also the mono-alkoxylated and bis- alkoxylated amine surfactants.
