Definitions

• the subject of DE-OS 2 609 752 is a clear, cold-resistant detergent concentrate with a solids content of up to 55% by weight, containing 8 to 18% by weight of a potassium fatty acid soap, which is different from Derives fatty acids with 12 to 18 carbon atoms and consists predominantly of oleic acid, 10 to 25 wt .-% of ethoxylated alcohols with 8 to 12 carbon atoms and an average of 5 to 10 ethylene glycol ether groups and 4 to 10 wt .-% sodium alkylbenzenesulfonates with 10 to 14 carbon atoms in the Alkyl group, also optical brighteners and conventional solubilizers or water-miscible solvents.
• Means of this type are primarily intended for use in large laundry companies with automatically operated washing, drying and ironing machines, in which the individual work cycles overlap.
• the composition of a detergent suitable for this must be coordinated in such a way that there are no disturbances affecting the functioning of the machine or interrupting the work cycle. It has now been shown in certain modern washing machines that when using conventional detergents and to a certain - but to a lesser extent - even when using the agents according to DE-OS 2 609 752, the loading and unloading flaps running in grooves no longer have the necessary ease of movement and therefore no longer open and close according to the clock. Problems with spinning and hot ironing can also occur. For example, compacted laundry in self-centrifuging washing machines can only be detached from the drum wall with additional force, or problems can arise during transport and smoothing of the laundry on the mangling line.
• the potassium soaps listed under A) are derived from fatty acids of natural or synthetic origin, which consist of 60 to 100% by weight, preferably 65 to 95% by weight, of lauric acid, myristic acid or oleic acid. Mixtures of lauric acid and myristic acid should consist of at least half, preferably at least two thirds, of lauric acid.
• polyunsaturated fatty acids for example linoleic acid, can also be present in the fatty acids in proportions of 0 to 25, preferably 0.1 to 15% by weight.
• the proportion of saturated fatty acids with 16 to 18 carbon atoms is 0 to at most 20, preferably 1 to 15% by weight, the proportion of stearic acid expediently not to exceed 5% by weight and in particular 3% by weight.
• Suitable fatty acid mixtures have, for example, the following composition (in% by weight):
• composition II Agents based on composition II are particularly preferred.
• the ethoxylated alcohols listed under B) are derived from native or synthetic alcohols, in particular oxo alcohols having 8 to 14, preferably 9 to 12, carbon atoms.
• the oxo alcohols can be linearly branched or methyl-branched in the 2-position. Mixtures of native alcohols and alcohols obtained by oxo reaction are also suitable.
• the number of ethylene glycol ether groups is on average 5 to 10, preferably 6 to 8.
• the proportion of ethoxylated alcohols in the liquid concentrates should be 5 to 9, preferably 6 to 8% by weight.
• Component C) consists of linear sodium alkylbenzenesulfonate, in particular dodecylbenzenesulfonate, in proportions of 4 to 10, preferably 6 to 8,% by weight.
• Optical brighteners of the formula F are preferably used, in which R 1 and R 2 represent morpholino, diethanolamino or anilino residues.
• the optical brighteners are in proportions of 0.05 to 1, preferably from 0.1 to 0.7% by weight.
• Component D) serves to make the solution or the wash liquor alkaline.
• the amount of potassium hydroxide is preferably such that it exceeds the stoichiometric amount required to form the potassium fatty acid soaps by 10 to 50 mol percent, in particular by 20 to 35 mol percent.
• the triethanolamine (component F) improves the cold resistance of the concentrates and is present in amounts of up to 6% by weight, preferably 2 to 5% by weight.
• Component G) consists of aliphatic C 3 -C 3 alcohols, ie methanol, ethanol, propanol and in particular isopropanol, and of the mixtures of the alcohols mentioned.
• the content of these alcohols in the compositions is preferably 12 to 18% by weight.
• Agents with fractions of less than 12% of the alcohols mentioned can also contain hydrotropic ether alcohols derived from C 1 -C 4 monoalcohols or ethylene glycol or propylene glycol or diglycols, or hydrotropic alkylbenzenesulfonates with short alkyl chains.
• Suitable are, for example, the monomethyl, monoethyl, monopropyl, monoisopropyl or monobutyl ether of ethylene glycol and, from the group of the alkylbenzenesulfonates, the toluenesulfonate, ethylbenzenesulfonate, cumene sulfonate and xylene sulfonate in the form of the potassium or preferably sodium salts.
• the proportion of these solution-improving substances can be up to 5 ° / o.
• the water content of the detergent concentrate should not fall below 30% by weight. There are no limits in the direction of more dilution, but it is advisable not to exceed a water content of 55% in order to save on packaging and transport volume. In general, a water content of 30 to 50% by weight is sufficient to achieve optimal results, i.e. Such concentrates remain clear, even when stored for several weeks at a temperature of -10 ° C. and do not tend to solidify, gel or separate under such extreme conditions.
• additives may also include biocides, fragrances, dyes, stabilizers, sequestering agents, neutral salts and optical brighteners of other constitution, but the proportion of such additives should not total 10% by weight. exceed and preferably less than 5 wt .-%, in particular less than 2 wt .-%, so that a negative impact on the cold stability is avoided.
• the laundry detergents according to the invention are used in an amount of 3 to 10 g per kg of dry laundry, preferably using softened water. They are suitable as pre or main detergents for textiles of all kinds, e.g. those made of cellulose, synthetic and semi-synthetic fibers. Preferred areas of application are fully automatic washing, drying and ironing devices, as are customary in large commercial laundries.
• the agents can be added as washing-strengthening additives to washing liquors of conventional composition, ie those which, in addition to surfactants, also contain, for example, washing alkalis, phosphates, sequestering agents, bleaching agents and anti-graying substances.
• a liquid washing alkali concentrate which is particularly suitable for use in large automatic washing systems and with which the agent according to the invention can be combined when used has the following composition:
• the potassium soaps used in the recipes still had the following fatty acid composition (in% by weight):
• Component B An oxo alcohol of chain length C, -C " with 7 ethylene glycol ether groups was used as the ethoxylated alcohol (component B).
• Component C consisted of linear Na dodecyl benzenesulfonate.
• the sodium salt of the compound of the formula I in which R 1 and R 2 were morpholino radicals was used as the optical brightener (component D).
• Component G consisted of isopropanol.
• the component “salts” means small amounts of Na 2 SO 4 and NaCI which were present as accompanying substances of the alkylbenzenesulfonate and the optical brightener.
• the composition is shown in Table 2.
• the soap including the excess potassium hydroxide solution in the form of a 65% aqueous paste with the ethoxylate and. the alkylbenzenesulfonate, which was in the form of a 50% strength aqueous solution, mixed with one another, the optical brightener dissolved in isopropanol was then stirred in and finally triethanolamine and water were added to the stated amount.
• the concentrates were in the form of yellowish, clear solutions which had a low viscosity at room temperature and which remained clear and homogeneous when stored for three weeks in a climatic cabinet at -10 ° C and + 50 ° C. A multiple temperature change between + 50 ° and -10 ° C also did not change the appearance and behavior of the samples.
• the concentrates were miscible with water in all proportions.
