- the content of optical brighteners or brightener mixtures in the agent is generally not more than 1% by weight, preferably 0.05% by weight to 0.5% by weight. In a preferred embodiment of the invention, the agent is free from such active ingredients.
- the usual foam regulators which can be used in the agents according to the invention include, for example, polysiloxane / silica mixtures, the mixtures contained therein finely divided silica is preferably silanated.
- the polysiloxanes can consist of both linear compounds and crosslinked polysiloxane resins and mixtures thereof.
- Other defoamers are paraffin hydrocarbons, in particular microparaffins and paraffin waxes, the melting point of which is above 40 ° C., saturated fatty acids or soaps with in particular 20 to 22 carbon atoms. for example sodium behenate, and alkali metal salts of phosphoric acid mono- and / or dialkyl esters, in which the alkyl chains each have 12 to 22 carbon atoms.
- Sodium monoalkyl phosphate and / or dialkyl phosphate with C 16 to C 18 alkyl groups is particularly preferably used.
- the proportion of foam regulators can preferably be 0.2% by weight to 2% by weight. In many cases, the tendency to foam can be reduced by a suitable selection of the surfactants, so that the use of defoaming active substances in a preferred embodiment of the invention can be dispensed with entirely.
- the pasty detergents according to the invention are preferably essentially free of water and organic solvents in the presence of bleaching agents, that is to say in this case polyol according to formula (III) is preferably present instead of water.
- “Substantially free of water” is understood to mean a state in which the content of free water, that is to say which is not in the form of water of hydration and constitutional water, is below 3% by weight, preferably below 2% by weight and in particular below 1 % By weight.
- dehydrating agents can also be used, for example in the form of salts which bind water of crystallization, such as anhydrous sodium acetate, calcium sulfate, calcium chloride, sodium hydroxide, magnesium silicate, or metal oxides such as CaO, MgO , P 4 O 10 or Al 2 O 3 can be used.
- Such dehydrating agents with which the water content of agents according to the invention can be reduced to particularly low values, are present in quantities of preferably 1% by weight to 10% by weight and in particular 2% by weight to 8% by weight Agents according to the invention available.
- the carboxylic acid salts of the formula I and the solubilization system from the alcohols or ethers of the formula II and water and / or the polyols of the formula III are expediently mixed to form a homogeneous premix and the solids and, if appropriate, further constituents are incorporated into this premix , If the particulate solids are not sufficiently fine, one or more grinding steps can be inserted.
- a paste-like agent according to the invention preferably has a viscosity at 25 ° C. in the range from 80,000 mPas to 250,000 mPas, in particular 100,000 mPas to 250,000 mPas, measured with a Brookfield rotary viscometer (spindle No. 7) at 5 revolutions per minute , Under otherwise identical conditions, the viscosity at 50 revolutions per minute is preferably 20,000 mPas to 80,000 mPas.
- the paste-like detergent and cleaning agent preferably has a viscosity at room temperature such that it is not flowable under the action of gravity.
- an agent according to the invention preferably has a considerable amount, usually 100 to 2000 -foldly lower viscosity, which is at a shear rate of 10 s * 1 and otherwise the same measurement conditions, in particular in the range from 40 mPas to 60 mPas
- the numerical values for viscosity refer to the reading after a, in order to take into account any thixotropy effect of the paste Measuring time of 3 minutes
- the lowering of the viscosity under shear is largely reversible, that is to say n After the shear has ended, the agent returns to its original physical state without the occurrence of segregation.
- An agent according to the invention normally has a density in the range from 1.2 kg / 1.4 to 1.4 kg / 1.
- the agent according to the invention can be metered using conventional devices for metering pastes, as described, for example, in international patent application WO 95/29282, German patent application DE 196 05 906, German patent DE 44 30 418 or European patent EP 0 295 525 and EP 0 356 707 have been described.
- a device which is particularly well suited for metering structurally viscous pasty detergents is known, for example, from international patent application WO 95/09263 and is preferably used for metering structurally viscous pastes according to the invention.
- the detergents and cleaning agents according to the invention can optionally also be filled into film bags already pre-portioned, water-soluble films being used in particular with essentially water-free agents according to the invention.
- Such films are described, for example, in European patent application EP 0 253 151.
- the table below gives examples of the composition of detergents according to the invention (Ml to M8).
- the pasty detergents had very good storage stability and, despite the absence of alkoxy group-containing nonionic surfactant and synthetic anionic surfactant, had an excellent cleaning performance which at least corresponded to that of known pasty detergents containing alkoxy group-containing nonionic surfactant and synthetic anionic surfactant.
