Blonding composition tablets

A method for producing blonding tablets in a tablets press, in which

• i) a material to be compressed including, based on its weight,
• a) from 10 to 70 wt. % of peroxydisulfate(s),
• b) from 0 to 20 wt. % of oil(s),
• c) from 1 to 20 wt. % of disintegrant made of cellulose-containing material which is compacted before being admixed to the components a) and b) and is present in the form of a compacted granulate having a density of from 0.3 to 1.5 g/cm3,
• is filled into a die, the base of which is formed by a lower press die;
• ii) the material in the die is compressed between the lower press die and an upper press die at a pressing force of from 10 to 60 kN to form a tablet;
• iii) an additional layer or a plurality of additional layers of material to be compressed are optionally applied to the upper face of the tablet and are compressed to form a (then multi-layer) tablet as in step ii);
• and
• iv) the tablet is removed from the die.
