  • Patent number: 4931202
    Abstract: Highly alkaline detergent compositions are prepared by mixing together, in a mixing device, a melt of alkaline material with a hardness sequestering agent, such as an alkali metal complex phosphate sequestrant. The resulting mixture is, then, pelletized on a chill belt. A source of solid active chlorine pellets is combined with the pelletized mixture. Chlorine degradation is essentially eliminated by combining the alkaline material pellets with the pelletized chlorine source.
    Type: Grant

  • Patent number: 4823441
    Abstract: Highly alkaline detergent compositions are prepared by mixing together, in a mixing device, a melt of alkaline material with a heat-alkaline sensitive material, such as, an alkali metal complex phosphate sequestrant and/or an active-chlorine source. The resulting mixture is, then, pelletized on a chill belt. Because of the short contact time between the molten alkaline material and the sequestrant and the rapid solidification, reversion of the sequestrant, particularly, a phosphate sequestrant, is substantially reduced.
