BLEACH ACTIVATOR GRANULES AND PREPARATION THEREOF |
摘要 |
<p>C 593 (R) Effervescent bleach activator granules for use in washing and/or bleaching compositions comprising a bleach activator, a peroxoborate and a binding material are disclosed. Preferred granules include an alkali metal perborate monohydrate, preferably in a proportion at least equal to the amount of the bleach activator. These granules have the advantage that the reduction of mechanical loss when used in washing machines combined with a fast dissolution of and reaction between the bleach activator and the percompound in close proximity at a high local pH should improve the bleach performance, particularly in the low/medium temperature range to a substantial degree.</p> |
