Concentrated flowable washing agent preparation having improved properties

A flowable washing agent preparation containing, based on its total weight, a) 2 to 3 wt. % alcohol polyalkoxylate having a weight-average molecular weight Mw in the range of 600 g/mol to 10,000 g/mol, obtainable by reacting diols or triols having primary and/or secondary OH groups, and having a molecular weight Mw in the range of 60 g/mol to 200 g/mol, with alkylene oxides;

• b) 2 to 3 wt. % polyalkoxylated polyalkyleneimine obtainable by reacting polyalkyleneimines with alkylene oxides;
• c) 24 to 57 wt.% surfactants consisting essentially of:
• i. 5 to 15 wt. % alkyl ether sulfate;
• ii. 15 to 28 wt% primary C8-18 alcohol ethoxylate;
• iii. 4 to 12 wt% fatty acid;
• and
• iv. less than 2 wt.% of C8-18 alkylbenzene sulfonates;
• d) less than 20 wt. % water;
• wherein the weight ratio of alcohol polyalkoxylate to polyalkoxylated polyalkyleneimine is 3:2 to 2:3;
• and
• wherein the alcohol polyalkoxylate is selected from compounds of general formula (I)
• in which R represents a linear, optionally branched or optionally cyclic alkyl group having 1 to 12 C atoms or a —(CH2CHR′O)n″—(CH2CHR″O)m″—H group,
• R′ and R″, independently of one another, represent H, CH3 or CH2CH3,
• n, n′ and n″, independently of one another, represent numbers from 0 to 30, and
• m, m′ and m″, independently of one another, represent numbers from 0 to 30,
• with the proviso that the sum n+n′+n″+m+m′+m″ is at least 14.
