Abstract
The invention describes a stable liquid washing agent or liquid cleaning agent having a yield point and very good dispersing properties. The agents contain anionic and nonionic surfactants as well as inorganic salt, at a specific ratio to one another. The invention also relates to use of the liquid washing agent or liquid cleaning agent, and to a method for manufacturing it.
Claims11
A liquid washing or cleaning agent having a yield point, comprising:
- a) 7 to 20 wt % anionic surfactant selected from the group consisting of sulfonate surfactants, sulfate surfactants, and mixtures thereof;
- b) 3 to 15 wt % nonionic surfactant selected from the group consisting of alkoxylated fatty alcohols, alkoxylated fatty acid alkyl esters, fatty acid amides, alkoxylated fatty acid amides, polyhydroxy fatty acid amides, alkyl phenol polyglycol ethers, amine oxides, alkylpolyglucosides, and mixtures thereof;
- c) 8 to 25 wt % of an inorganic salt selected from the group consisting of sodium chloride, potassium chloride, sodium sulfate, sodium carbonate, potassium sulfate, potassium carbonate, sodium hydrogen carbonate, potassium hydrogen carbonate, calcium chloride, magnesium chloride, and mixtures thereof;
- and
- d) 0.5 to 5 wt % ethanol and/or glycerol,
- wherein the ratio of the total quantity of anionic and nonionic surfactant to inorganic salt is in the range from 1.4:1 to 1:1, and wherein the washing or cleaning agent is packaged in a water-soluble envelope.
