Abstract
A flowable washing agent preparation containing, based on the total weight thereof, i) 20 to 80 wt. % surfactant; ii) 2 to 15 wt. % fatty acid; iii) 0.3 to 8 wt. % of the salt of a divalent cation; iv) 0.01 to 2 wt. % pigment; v) 8 to 35 wt. % solvent; and a washing method using same.
Claims19
A flowable washing agent preparation containing, based on the total weight thereof,
- i) 20 to 80 wt. % surfactant consisting of anionic and nonionic surfactant, the anionic surfactant being 20 to 60 wt. % based on the total weight of the washing agent preparation;
- ii) 2 to 15 wt. % fatty acid;
- iii) 0.4 to 6 wt. % of a salt of a divalent cation;
- iv) 0.01 to 2 wt. % pigment selected from the group of white pigments having a refractive index above 1.8;
- v) 8 to 35 wt. % solvent;
- and
- vi) 0.5 to 4 wt. % of a salt of monovalent metal cation;
- wherein the preparation has a turbidity above 60 NTU;
