Definitions
- kits of parts comprising a detergent tablet as described above and instructions stating that no rinse aid or salt is to be added to the dishwashing machine.
- Delayed dissolution of region (A) may be achieved by selecting particulate components that are encapsulated with a component which is slow dissolving or partially soluble in water.
- encapsulating materials include cellulose and cellulose derivatives e.g. cellulose acetate, cellulose acetate plithalate (CAP), hydroxypropyl Methyl Cellulose (HPMC), carboxymethylcellulose (CMC) and mixtures thereof.
- the hydroxypropyl methylcellulose polymer preferably has a number average molecular weight of 50,000 to200,000 and a viscosity of a 2 wt.% aqueous solution at 25"C (ADTMD2363) of 50,000 to 120,000 cps.
- An especially preferred hydroxypropyl cellulose polymer is Methocel O J75MS-N wherein a 2.0 wt.% aqueous solution at 25'C has a viscosity of about 75,000 cps.
- Other preferred encapsulating materials include gelatine of bloom strength in the range of from 30 to 200, preferably from 75 to 200.
- the coating layer preferably comprises a material that becomes solid on contacting Region A within preferably less than 15 minutes, more preferably less than 10 minutes, even more preferably less than 5 minutes, most preferably less than 60 seconds.
- the coating layer is water- soluble.
- Preferred coating layers comprise materials selected from the group consisting of fatty acids, alcohols, diols, esters and ethers, adipic acid, carboxylic acid, dicarboxylic acid, polyvinyl acetate (PVA), polyvinyl pyrrolidone (PVP), polyacetic acid (PLA), polyethylene glycol (PEG) and mixtures thereof.
- Alicyclic and heterocyclic polycarboxylates include cyclopentane-cis,cis,cis-tetracarboxylates, cyclopentadienide pentacarboxylates, 2,3,4,5-tetrahydroturan - cis, cis, cis-tetracarboxylates, 2,5-tetrahydrofuran - cis - dicarboxylates, 2,2,5,5-tetrahydrofuran- tetracarboxylates, 1,2,3,4,5,6-hexane - hexacarboxylates and carboxymethyl derivatives of polyhydric alcohols such as sorbitol, mannitol and xylitol.
- Aromatic polycarboxylates include mellitic acid, pyromellitic acid and the phthalic acid derivatives disclosed in British Patent No. 1,425,343.
- the silica is in the product in such a form that it can dissolve when added to the wash liquor. Therefore, addition of silica by way of addition anti-foam particles of silica and silicone oil is not preferred.
- the particle size of the silica material of the present invention may be of importance, especially as it is believed that any silica material that remains undissolved during the washing process, may deposit on the glass at a later stage.
- compositions of the present invention having a pH of 9 or less preferably will be substantially free of alkali metal silicate.
- the present invention preferably relates to processes of mechanically washing soiled articles with a wash liquor at a temperature of below 55°C.
- Product 2 region B are at 21.25g + 3ml separate Rinse Aid, regenerated ion exchange.
- Product 3 Reference product using regenerated ion exchange and standard products (Sun tablet and rinse aid as sold in France).
- Test regime Product 4 (region A & B) above at 25g total dosage. No salt or Rinse aid added extra.
- Product 6 reference product using regenerated ion exchanger and standard products. (Sun tablet and rinse aid ex France).
