Abstract (en)
[origin: WO0138477A1] A method for the production of particulate washing or cleaning agents, or the pre-cursors suitable for production thereof, is disclosed, whereby a free-flowing acid component is coated on a particle, at least proportionally comprising an alkaline washing or cleaning agent containing material. The proportion of coated acid component is dependent on the radius according to the formula mc/(mc+mp) = c.1/r, in which mc = the mass of acid component, mp = the mass of the particle, r = the radius of the particle and c = a factor of from 0,5 length units to 20 length units.
