Abstract

Improvements made to a process for obtaining sodium perborate grains by crystallizing these grains from a supersaturated perborate solution, according to which perborate grains of global chemical formula NaBO2.H2O2.3H2O are obtained, which have a spherical shape associated with an apparent density between 750 and 850 g/l, for a granulometry between 250 and 450 microns and endowed with a high resistance to shock and friction, these improvements being characterized by the introduction into the supersaturated solution of at least one Anionic surfactant product containing at least one sulfate and/or sulfonate function linked to at least one hydrocarbon alkyl chain of 8 to 22 carbon atoms and further containing at least one unsaturated bond and at least one oxygen heteroatom.
