  • Publication number: 20060234900
    Abstract: A method for producing phosphonate in the form of a solid or a gel is provided. The solid can be prepared by neutralizing phosphonic acid as a result of mixing a neutralization composition comprising phosphonic acid and a source of alkalinity to provide phosphonate in a solid form without a step of drying. The gel can be prepared by neutralizing phosphonic acid as a result of mixing a neutralization composition comprising phosphonic acid, a source of alkalinity, and silicate to provide phosphonate in a phosphonate composition in the form of a gel. Methods for producing detergent compositions and detergent compositions are provided.

  • Publication number: 20060191851
    Abstract: A method for treating feedwater is provided. The method includes steps of introducing a treatment composition into a feedwater stream to provide a treated feedwater stream containing scale inhibitor at a concentration of at least about 0.1 ppm, and combining the treated feedwater stream with a detersive composition. The scale inhibitor can include a phosphate scale inhibitor, a carbonate scale inhibitor, or a combination of a phosphate scale inhibitor and a carbonate scale inhibitor. The detersive composition can be provided as a cleaning composition, a rinse agent composition, or a drying agent composition. A treatment composition and an apparatus for treating feedwater are provided.
