Claims
- 1. An improved rinsing composition for cleaning of hard surfaces and for preventing depositions thereon, said composition consisting essentially of:
- as a builder, 30-50 weigth-% of a crystalline layer sodium silicate of the general formula NaMSi.sub.x O.sub.2x+1 .multidot.y H.sub.2 O, in which M stands for sodium or hydrogen, x stands for a number from 1.9 to 4 and y stands for a number from 0 to 20,
- as a co-builder, 0.1-7.5 weight-% of at least one substance selected from the group consisting of hydroxymethylene carboxylates, maleic acid anhydride, ethylene vinyl ether or maleic acid anhydride/acrylic acid copolymers or the sodium salts thereof,
- 0-45 weight-% of a filler,
- 10-25 weight-% of an alkali carrier,
- 1-2 weight-% of a surfactant, and
- 1-5 weight-% of an active chlorine carrier,
- said composition being free of phosphate.
- 2. The rinsing composition as claimed in claim 1, containing 0.1-3 wt % pulverulent co-builder.
- 3. The rinsing composition as claimed in claim 1, containing 0.3-7.5 wt % liquid co-builder.
- 4. The rinsing composition as claimed in claim 1, containing sodium dichloroisocyanurate or chlorine bleach liquor as the active chlorine-carrier.
- 5. The rinsing composition as claimed in claim 1, containing sodium sulfate as the filler.
- 6. The rinsing composition as claimed in claim 1, containing sodium carbonate, caustic soda or a water-soluble alkali metal silicate as the alkali carrier.
- 7. The rinsing composition as claimed in claim 1, containing, as the surfactant, as least one substance selected from the group consisting of chlorine-stable block polymers of long chain aliphatic alcohols with ethylene oxide and/or propylene oxide groups or modified fatty alcohol polyglycolethers.
