FIELD: detergent production. SUBSTANCE: supersaturated solution is crystallized to give particles that are covered with alkali metal salt of inorganic acid such as HCl, H2SO4, H2CO3, H2B4O7, H2SiO4. Covering is carried out in tub for subsequent crystallization provided with stirrer at temperature below crystallization temperature. Covered particles are separated by centrifugation and dried. As shell material, desalting agent contained in mother liquors accompanying suspension of peroxy salts is used. EFFECT: facilitated covering procedure. 10 cl, 4 ex
