Abstract (en)
[origin: EP0523681A2] The composition consists of a low-foam surfactant and, where appropriate, of a polycarboxylic acid and has the composition 5 - 20 % by weight of low-foam surfactant 2 - 10 % by weight of an organic acid 3 - 8 % by weight of a polycarboxylic acid 0 - 5 % by weight of nitrilotriacetate 3 - 5 % by weight of emulsifier 2 - 5 % by weight of thickener 1 - 4 % by weight of alkali remainder water which has a pH between 4 and 6, preferably about 5. The composition is produced by initially making a paste of the powdered thickener in a (liquid) non-ionic anhydrous surfactant, and adding the resulting dispersion to the liquid (dissolved) surfactant, after which the resulting solution is neutralised to a pH between 4 and 6, preferably 5, with alkali, preferably triethanolamine, for the purpose of dissolving the powdered thickener and gelling the liquid.
