Definitions

• the object of the invention was therefore to provide a dosage form for manual cleaning agents, especially HGSM, or pretreatment to remove stubborn To find dirt that does not have the disadvantages described above.
• WO 94/14941 relates to aqueous neutral or slightly alkaline, automatic dishwashing detergents, that are free of anionic and cationic surfactants.
• the machine Dishwashing detergents can be enclosed in water-soluble or water-dispersible containers be made of gelatin, for example.
• the use of encapsulated Active substances containing a surfactant or a surfactant mixture as a hard dishwashing liquid or cleaning agent is not mentioned in the document.
• EP-A 0 261 754 relates to a mixture of amine salts and long-chain alkyl ether sulfates and liquid polyethylene glycols as well as glycerin, encapsulated in an elastic Gelatin capsule.
• the possibility of an active substance containing a surfactant or a Capsule mixture, encapsulated and filled gelatin capsules as a dishwashing liquid or use cleaning agents is not possible from the document forth.
• the invention therefore relates to the use of a water-soluble or water-dispersible material-coated active substance containing in essential water-free surfactant or surfactant mixture, as a manual cleaning agent, especially hand dishwashing liquid (HGSM) or pretreatment agent for removal stubborn dirt.
• HGSM hand dishwashing liquid
• a “manual cleaning agent” is used in the context of the present invention understood a cleaning agent that the user acquired in concentrated form is dissolved in water at a temperature of up to about 60 ° C for use becomes. With this cleaning liquor, hard surfaces such as glass, Ceramics, concrete, metal, as well as painted or polished surfaces can be cleaned. Of the The cleaning process is carried out manually by the user. Under “manual Cleaning” is understood in the sense of the present invention to be a cleaning process where the user is in manual contact with the object to be cleaned. Under “Manual contact” is also understood to mean a contact that can be established with the help of a mechanical aids, for example a rag, a sponge, a brush or a scrubber.
• the time it takes for the container to at least partially dissolve is in about 35 ° C warm water at about 10 to 50 seconds, preferably at about 20 to 40 seconds.
• the dissolution process can be supported by stirring.
• the casing preferably consists of a material that is at least one natural or synthetic polymer or a mixture of two or more thereof contains.
• the material from which the covering consists preferably contains gelatin, Polyvinyl alcohol, polyethylene glycol, cellulose ether, alginic acid and / or alginates or Pectic acid or a mixture of two or more thereof.
• the material, from which the covering is made contain additives which increase the elasticity and Affect water solubility.
• the material from which the wrapper is made consists of gelatin and a plasticizer, for example glycol, glycerin or Sorbitol.
• the proportion of plasticizers in the material from which the casing is made is usually about 10 to about 40% by weight.
• Anionic surfactants from the group of alkyl sulfates and alkyl ether sulfates are particularly preferred in the context of the present invention. These include, for example, surfactants of the general formula I. and the surfactants of the general formula II wherein R 1 and R 3 each independently represent aliphatic, linear and / or branched C 6-22 alkyl radicals and / or aromatic, optionally substituted with C 1-18 alkyl groups, R 2 represents hydrogen and / or one or several C 1-4 alkyl radicals, x stands for numbers from 0.1 to 6 and M stands for metal cations or ammonium ions.
• a pH value is usually required for the cleaning effect of a pretreatment agent strongly alkaline range (greater than about pH 9) makes sense.
• Surfactants practice mainly a function as a wetting agent for better wetting of the treated Surfaces with the cleaning liquor, which is why all surfactants usually with sufficient network effect are suitable for this purpose.
• the essentially water-free surfactant mixture can still be nonionic Contain surfactants.
• strongly foaming or weakly foaming non-ionic Surfactants are used.
• nonionic surfactants are fatty alcohol polyglycol ethers, alkylphenol polyglycol ethers, Fatty acid polyglycol esters, fatty acid amide polyglycol ethers, Fatty acid amine polyglycol ethers, alkoxylated triglycerides, alkyl oligoglycosides, fatty acid N-alkyl glucamides, Polyol fatty acid esters, sugar esters, sorbitan esters and polysorbates.
• the manual cleaning agents or HGSM according to the invention preferably contain addition products of alkylene oxides to linear, aliphatic C 8-16 alcohols in the active substance as nonionic surfactant or as nonionic surfactants.
• Preferred alkylene oxides are ethylene oxide and propylene oxide. Ethylene oxide is particularly preferred.
• Crystalline alkali silicates for example sodium water glass (module 2), and finely divided alkali alumosilicates, in particular zeolites of the NaA type, can also be regarded as useful sequestering agents in the sense of the present invention.
• Suitable zeolites have a calcium binding capacity in the range from 100 to 200 mg CaO / g (according to the information in DE-C 24 12 837). Their particle size is usually in the range from 1 ⁇ m to 10 ⁇ m. They are used in dry form. The water contained in bound form in the zeolites does not interfere in the present case.
