Abstract (en)

[origin: GB2309976A] Particulates suitable for incorporation into granular detergent compositions comprise a) 1% to 50% of the metal-containing bleach catalyst b) 40% to 99% of the encapsulating material and c) 0.5% to 20% water. Detergents containing the particulates are typically automatic dishwashing or laundry compositions or hard surface cleaners. Catalysts are preferably Mn or Co containing and particulates are 10 - 450 micron size. Suitable encapsulating materials are gelatines, dextrin or gum Arabic.
