Abstract
A flowable washing agent preparation containing, based on the total weight thereof, a) 1 to 7 wt. % of polyacrylic acid; b) 1 to 7 wt. % of polyalkoxylated polyalkyleneimine, which can be obtained by reacting polyalkyleneimines with alkylene oxides; c) 10 to 30 wt. % of non-ionic surfactant; d) less than 20 wt. % of water; wherein the weight ratio of polyacrylic acid to polyalkoxylated polyalkyleneimine is 3:1 to 1:3, and to a textile washing method using these washing agent preparations.
Claims18
A flowable washing agent preparation comprising, based on the total weight thereof,
- a) 1 to 7 wt. % of polyacrylic acid;
- b) 2 to 7 wt. % of polyalkoxylated polyalkyleneimine, which can be obtained by reacting polyalkyleneimines with alkylene oxides;
- c) 10 to 30 wt. % of non-ionic surfactant, wherein the non-ionic surfactant is selected from the group consisting of ethoxylated primary C8-18 alcohols having a degree of alkoxylation of ≥4;
- d) less than 20 wt. % of water;
- wherein the weight ratio of the polyacrylic acid to the polyalkoxylated polyalkyleneimine is 3:2 to 2:3, and
- wherein the washing agent preparation contains less than 2 wt. % of C8-18 alkylbenzene sulfonates.
