Detergent compositions |
(57) A tablet of compressed detergent powder contains the inorganic persalt bleach, sodium
perborate, in conjunction with one or more bleach-sensitive ingredients - tetraacetylethylenediamine
or similar bleach activator, enzyme, fluorescer, or any combination of these - as
well as detergent-active compounds, detergency builders and optionally other ingredients.
The persalt is not segregated from the bleach-sensitive ingredients but, surprisingly,
the tablet is stable with no more loss of bleach, enzyme or fluorescer performance
on storage than in a powder of the same composition.
