Definitions
- the present invention relates to water-based cleaning agents with pasty to solid consistency based on alkali metal hydroxide.
- the cleaning agents contain alcoholates to achieve the desired consistency.
- the degree of hardness and the duration of the hardening of the cleaning agent can be checked by a specific sequential addition of further components.
- Highly alkaline cleaning agents are now commercially available in a wide variety of forms, e.g. B. as a powder, as granules, as a liquid, as a melting block or as a tablet produced by compression.
- a high level of homogeneity of the cleaners obtained is also particularly desirable, but this is often difficult to achieve with solid cleaners. This problem is less common with liquid cleaners that can be easily stirred.
- the homogeneity of a liquid, a viscous liquid or a stirrable paste would then be desired, which then solidifies into a solid, controllable, variable strength in order to utilize its advantages in storage and transport and metering at this stage. It would be particularly desirable if the stirrability were maintained at temperatures down to about 40 ° C., since less temperature-stable components could then also be mixed in.
- the object of the present invention is to provide highly alkaline cleaning agents of a general nature for textile surfaces, based on alkali hydroxide, preferably potassium or sodium hydroxide, particularly preferably sodium hydroxide, but preferably those for cleaning hard surfaces, eg. B. dishes, and in particular cleaning agents for the commercial cleaning of dishes to provide the advantages of powders and liquids on the one hand and the On the other hand, combine the advantages of tablets and melting blocks.
- cleaning agents are to be provided which have a solubility defined under the most varied of application conditions, but on the other hand are transport-stable and storage-stable and, moreover, can be dosed quickly, easily and precisely, which are not dusty and can be produced without great technical effort and are easy to fill .
- stirrability during production a controllably variable consistency and a delayed hardening during the production of solid cleaning agents would offer great advantages and should be taken into account.
- a method should be developed that allows less temperature-stable substances to be incorporated below 42 ° C if necessary, without endangering the other tasks. As with any technical process, it is of course also necessary to achieve a given effect under the most inexpensive conditions possible with regard to raw materials and production conditions.
- German published patent application DE-OS-31 38 425 theological behavior of the cleaners described there is described in such a way that a gel-like paste is liquefied and easily liquefied by the action of mechanical forces, for example by shaking or pressure on a deformable storage bottle or tube or by means of a metering pump can be squeezed out of a spray nozzle.
- US Pat. No. 3,607,764 describes glass cleaning agents in solid form, which are diluted to form a sprayable solution. These agents contain, inter alia, sodium or potassium hydroxide, sodium or potassium tripolyphosphate, Sodium or potassium pyrophosphate, hydroxycarboxylic acid builder, a water-soluble nonionic surfactant, alkylene glycol ether and optionally sodium carbonate. A control of the viscosity or the strength in the sense of the present invention is not described.
- Japanese patent specification JA 84/182870 describes solutions of alkali metal hydroxides in glycols or alcohols which become viscous when neutralized with long-chain carboxylic acids and which have a pasty consistency when silicone oil is added, so that they can be used as pastes in leather greasing.
- Japanese patent specification JA 86/296098 describes anhydrous solid cleaning agents based on alkali hydroxides.
- the alkali carrier is mixed into alkanolamine and water-soluble glycol ether, whereby a solid cleaner is obtained.
- a technical lesson on variably reducing the strength and controlling the hardening process is not described.
- the present invention relates to an aqueous alkaline cleaning agent comprising a) aqueous alkali, preferably potassium and / or sodium hydroxide, preferably 42-55%, in an amount of 21 to 70% by weight, preferably 35 to 55% by weight based on the cleaning agent, and to build up an increased viscosity b) one or more alcoholates of the formula I.
- the cleaning agents according to the invention have a pasty or solid consistency, the transitions being fluid. They are preferably not pumpable at room temperature. However, the consistency according to the invention can also manifest itself, for example, in the form of cut resistance. Many of the solid cleaning agents according to the invention can still be poured during processing and can be pressed to give shape even after prolonged storage.
- the agents can harden after storage. This hardening process can proceed very quickly, especially when adding solid, finely divided alkali metal hydroxide. It is particularly advantageous to use up to 35% by weight, preferably 2 to 25% by weight, particularly preferably 5 to 15% by weight, of solid alkali metal hydroxide, based on the total agent.
- the hardening process can be delayed by adding surfactants, paraffin oil and polyhydroxy compounds.
- the delayable curing time is measured by continuing the stirring process after adding all the components and following it until it comes to a standstill as a result of the curing.
- composition at the point in time that is referred to as curing and that can be controlled a consistency in which it cannot be drained as desired through a drainpipe at the bottom of a production kettle, or can be spilled from an inverted beaker.
- Another object of the invention is a method for producing these agents.
- they are obtained by stirring the alcoholates of the formula I or the corresponding alcohols into the alkali metal hydroxide solution.
- Particularly preferred agents are obtained if thereafter foam inhibitors and / or builder components, then surfactants and / or paraffin oil and finally 0.1 to 35% by weight, preferably 2 to 25% by weight, based on the total agent, of solid alkali metal hydroxide, preferably potassium or sodium hydroxide, particularly preferably sodium hydroxide.
- Another object of the invention is the use of these agents for the mechanical cleaning of dishes and surfaces and for washing laundry.
- the choice of substance composition according to the invention requires no further additives apart from the alcoholate as thickening agent in order to achieve the desired strengthening effect according to the invention in aqueous sodium hydroxide solution.
- the consistency can be kept in an easily stirrable state at a suitable temperature by the preferred further addition of suitable amounts of paraffin oil, surfactants and solid alkali hydroxide over a period of time which is favorable in terms of application technology, i.e. a controlled delay in material hardening can be achieved.
- the water content is also a critical parameter; it is between 10 and 35% by weight, advantageously between 20 and 30% by weight.
- the pH of the cleaning agents according to the invention is above 13.
- the cleaning agents according to the invention can also contain other ingredients customary in alkaline cleaners, provided that the variable strength according to the invention is not lost as a result.

- the substances of the formula I are the alcoholates of commercially available alcohols, with the exception of the alcoholates of ethylene glycol and 1,2-propylene glycol. Differentiated properties are achieved with increasing alkyl chain content. The thickening effect of the alcoholates seems to gradually decrease with increasing chain length. Branches in the alkyl chain also appear to change the thickening process. Alcoholates of methanol, ethanol, propanol, isopropanol, glycerol and butylene glycol are preferably used as the compound of the formula I. The alcoholates can be easily prepared by the usual methods of organic chemistry. There is also the possibility of producing the alcoholates in situ by adding the corresponding alcohols dropwise to the alkali hydroxide solution. Depending on the position of the equilibrium, a certain amount of the alcohol corresponding to the alcoholate remains in the solution as such.
- the amount of alcoholate added should be about 0.5 to about 40% by weight, preferably about 1 to about 10% by weight, based on the total cleaning agent. Since the alcoholate is in equilibrium with the corresponding alcohol, any free alcohol that may be contained is to be included in the amount of alcoholate, in the case of polyhydric alcohols as monoalcoholate. Both anionic surfactants and cationic surfactants, amphoteric surfactants and non-ionic surfactants can be used as surfactants. The cleaning performance is decisively influenced by the amount of surfactants. The hardening time after adding all components depends in particular on their concentration. Depending on the application, z. B.
- a higher surfactant content is recommended, which is generally up to 30% by weight, preferably 0.1 to 15, particularly preferably 1 to 10% by weight and most preferably 2 to 4% by weight based on the total agent.
