FIELD: chemistry.
SUBSTANCE: composition is used advantageously in solid form and contains a nonionic surfactant R1-O-A-O-R2, where -O-A-O- residue is formed by polyalkylene glycol HO-A-OH, containing monomer units derived from (C2-C6)-alkylene glycol or a mixture of at least two different (C2-C6)-alkylene glycols; and a water-soluble ionic polymer formed from a monomer composition comprising one or more ethylenically unsaturated monomers. At that, the nonionic surfactant R1-O-A-O-R2 is contained in an amount of 0.05 wt % to 2.0 wt %, in terms of the total weight of the composition and has an HLB not exceeding 14, and the ionic polymer is water-soluble or water-swellable.
EFFECT: composition provides its flocculation function without degrading the individual components performance, with effective elimination of foaming and minimal consumption of surfactant.
