Abstract (en)
[origin: WO9820096A1] The invention relates to solid, effervescent bleach compositions comprising: (i) a bleach activator; (ii) an oxygen effervescence generator comprising a persulphate salt and a perborate salt, wherein the weight ratio of the persulphate salt to the perborate salt is in the range from about 0.8:1 to about 5:1; and (iii) a carbon dioxide efferverscence generator comprising a bicarbonate salt and an acid; wherein the weight ratio of the perborate salt to the bicarbonate salt is in the range from about 2:1 to about 20:1. The compositions provide excellent de-stain activity with improved effervescence and/or tablet disintegration. They are especially suitable in tablet form as denture cleansers.
