Claims22
A method of softening water in a fabric washing machine which method comprises the addition of an aqueous thickened water softening composition which consists essentially of:
- a) 2-10% wt. of a water-softening agent which is a partly neutralized water-soluble acrylic/maleic copolymer;
- b) 0-1% wt of a surfactant;
- c) water;
- and
- d) xanthan gum present in an amount of from 0.1% wt. to less than 1.0% wt. to the water of the washing machine,
- 10-20% wt. of sodium citrate,
- wherein the aqueous thickened water softening composition comprises 100% wt.
