Definitions

• the present invention relates to a skeleton salt-free, liquid detergent concentrate which, due to its surfactant composition in conjunction with specially selected fatty acid diethanolamides, has textile-softening and grip-improving properties, so that the textiles washed therewith do not require any aftertreatment with a special softener.
• liquid detergent formulations which contain more or less large amounts of fatty acid mono- or. have diethanolamides. These are always those alkanolamides which are derived from fatty acid mixtures with a high proportion of C, 2 C, 6 fatty acids, for example coconut fatty acids. these alkanolamides are said to increase the washing and foaming power or to improve skin tolerance. These remedies do not have an aviva effect. Examples of such agents are those according to DE 1 047 973, DE 2 022 064, DE 2 703 998 (US 4 153 570), DE 2 819 455, DE 3 022 767, DE 3 161 222, EP 38 101, US 2 861 956, U.S. 2,943,058.

• the number of attached ethylene oxide groups (EO) is 5 to 10.
• Ethoxylated alcohols whose HLB value is 9 to 14, in particular 11 to 13.5, have proven to be very suitable. Examples of this are ethoxylated coconut fatty alcohols, from which the preliminary alcohols (10 and fewer C atoms) are separated and essentially consist of lauryl and myristyl alcohol in addition to small amounts of cetyl and stearyl alcohol.
• ethoxylated oxo alcohols or alcohols produced by ethylene polymerization which essentially consist of alcohol mixtures with 12 to 16 carbon atoms.
• the degree of ethoxylation of these preferred alcohols or alcohol mixtures is in particular 6 to 9.
• the proportion of component (b) is 7 to 20% by weight, preferably 8 to 15% by weight.
• Suitable soaps (c) are sodium and potassium soaps and soaps from alkanolamines, in particular triethanolamine, which are derived from saturated and monounsaturated fatty acids having 12 to 18 carbon atoms. Because of their low cloud point, soaps from coconut fatty acids (after separation of the fatty acids with less than 12 carbon atoms) and oleic acid or from oleic acid-rich fatty acid mixtures and combinations of these soaps are particularly suitable. These soap mixtures are preferably used in the form of sodium soaps or as mixtures of sodium soaps and triethanolamine soaps.
• the proportion of soaps (c) is 6 to 16% by weight, preferably 8 to 15% by weight, based in each case on the fatty acid content.
• Component (d) includes fatty acid diethanolamides which are derived from monounsaturated fatty acids with 16 to 18 carbon atoms and their mixtures with saturated fatty acids of the same chain length, but the proportion of unsaturated compounds is at least 50% by weight, preferably at least 65% by weight .-%.
• Diethanolamides derived from oleic acid and palmitoleic acid and mixtures thereof with the corresponding palmitic acid and stearic acid derivatives such as those obtained from naturally occurring fatty acid mixtures rich in oleic acid, e.g. B. from tallow fatty acids or tall oil fatty acids, are accessible by isolating the unsaturated portions by known separation processes (network separation).
• Well usable fatty acid fractions contain e.g. B. 50 to 100 wt .-%, preferably 65 to 95 wt .-% oleic acid and 0 to 50 wt .-%, preferably 5 to 35 wt .-%, palmitic acid and stearic acid, small amounts in industrial mixtures, d. H. up to 5% of myristic acid may be present.
• the etharyolamides which can be prepared from these fatty acids by reaction with diethanolamine are technical mixtures which usually contain 85 to 95% by weight of N-acyl compound and 2 to 10% by weight of O-acyl compound.
• These usual additions do not interfere in the present compositions, but can be regarded as functional constituents, especially since the compositions already contain soap and, in a preferred embodiment, also alkanolamines.
• the proportion of component (d) is 7 to 20% by weight, preferably 8 to 15% by weight and in particular 10 to 12% by weight.
• Suitable sequestering agents are polycarboxylic acids and polyphosphonic acids.
• Suitable polycarboxylic acids are citric acid, nitrilotriacetic acid, ethylenediaminoetetraacetic acid and their higher homologues.
• Suitable polyphosphonic acids are aminotri- (methylenephosphonic acid), ethylenediaminetetra - (methylenephosphonic acid), diethylenetriaminepenta- (methylenephosphonic acid) and their higher homologues.
• the acids mentioned can be used as salts of sodium, potassium and of alkonolamines, e.g. B. of triethanolamine.
• Citric acid ethylenediaminetetra- (methylenephosphonic acid) and diethylenetriaminepenta- (methylenephosphonic acid) and mixtures thereof are particularly suitable. They are present in the agents in proportions of 0.2 to 3% by weight, preferably 0.4 to 2% by weight.
• Water-miscible solvents which are present in the compositions in proportions of 5 to 15% by weight, preferably 7 to 13% by weight, are alcohols, glycols, polyglycols and ether alcohols, such as methanol, ethanol, propanol, isopropanol, glycerol, Glycol, diethylene glycol, triethylene glycol and low molecular weight polyethylene glycols, propylene glycol and oligomeric propylene glycol ethers, furthermore ether alcohols, such as methyl propyl glycol, methyl butyl glycol or methyl ethyl glycol. Mixtures of ethanol and propylene glycol in a ratio of 1: 4 to 4: 1 are preferably used as solvents.
• Additional constituents which are advantageously added to the agents are enzymes, enzyme stabilizers, compounds for adjusting the pH, optical brighteners, hydrotropes, foam inhibitors, dyes or color pigments and agents which act as opacifiers or give the solutions a silky sheen.
• Suitable enzymes are proteases and amylases obtained from fungi or bacteria in a known manner and mixtures thereof, e.g. B. enzymes obtained from Bacillus subtilis or Bacillus licheniformis.
• the commercially available enzyme preparations usually also contain activators, such as calcium and magnesium salts, and extenders and binders. The content of the agents in these enzyme preparations is generally 0.1 to 1.5% by weight.
• the stability of the enzymes can be increased by adding alkanolamines, especially triethanolamine.
• the triethanolamine is expediently present in excess, as a result of which a desired weakly alkaline reaction of 7.2 to 9, preferably 7.5 to 8.5, can be set.
• Low molecular weight acids such as formic acid, acetic acid and lactic acid are suitable as further enzyme stabilizers, which, based on free acid, can be present in proportions of 0.1 to 2, preferably 0.2 to 1,% by weight. Due to the basic reaction of the agents, these acids are predominantly or completely in the form of their salts, e.g. B. as sodium, potassium or alkanolamine salts.
• Suitable foam inhibitors are water-dispersible silicones, e.g. B. dimethylpolysiloxanes, which can optionally be modified with polyglycol ether groups, and mixtures of such compounds with polysitoxane resins or finely divided silica, which is preferably silanated.
• the content of optical brighteners and silicon component foaming agents in the compositions can be in the order of 0.01 to 1% by weight.

• the agents according to the invention are notable for high washing and cleaning properties as well as favorable softening and grip-improving properties. They are suitable both for hand washing and due to their balanced foam behavior for use in washing machines.
