Dry effervescent granules and granular compositions comprising the same

摘要

The present invention discloses dry effervescent granules comprising an acid, carbonate/bicarbonate and optionally a binder, wherein said acid, carbonate and/or bicarbonate and optionally binder are in close physical proximity and granular compositions 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 characteristics and improved stain removal performance on soiled fabrics.
