  • Patent number: 6440926
    Abstract: The present invention discloses dry effervescent granules comprising an acid, carbonate source and optionally a binder, wherein said acid, carbonate source and optionally binder are in close physical proximity. The invention also discloses granular compositions, containing effervescence material comprising an acid and a carbonate source, which has an effervescence index (EI) of at least 50. The granular compositions may be obtainable by incorporating said pre-formed dry effervescent granules into said granular compositions, especially detergent compositions. Improved effervescence is obtained when diluting these granular detergent compositions with water to obtain a washing/soaking liquor, resulting thereby in improved dissolution/dispensing characteristic and improved stain removal performance on soiled fabrics.
