Abstract: It has emerged that blonding pastes of relatively high oil content that have been thickened by specific polymers are especially table when the persulfates employed satisfy certain criteria. Blonding tablets including, based on their weight, 10 to 70 wt % of peroxydisulfate(s), 0 to 30 wt % of oil(s) and 1 to 20 wt % of disintegrant(s) made from cellulosic material that before being admixed to components a) and b) and before tableting has been compacted and takes the form within the tablet of compacted granules with a density of 0.3 to 1.5 g/cm3 exhibit increased chemical and physical stability and can be mixed readily with oxidant preparations to produce blonding compositions with stable viscosity.
