Washing compsns - based on per cpds, activators, builders and surfactants with addition of hydrophobic microcrystalline silica

摘要

Microcrystalline silica dispersed among the other components or deposited on activator particles improves the storage stability of the compsn., unpleasant smell being eliminated. The compsn. contains (in wt.%): per cpds. (pref. perborates) 7-35; activator(s) for per cpds. (e.g. N-acyl or O-acyl cpds. or esters of (pyro)-carboxylic acids) 0.5-15; hydrophobic microcrystalline silica 0.1-15; surfactants 5-20; builders 10-70; and other conventional compounds 0-20.
