USE OF COMPOSITIONS FOR MACHINE DISHWASHING Russian patent published in 2016 - IPC C11D3/37 C11D1/72 

FIELD: chemistry.

SUBSTANCE: present invention relates to use of compositions containing (a1) at least one copolymer, which is produced as a result of copolymerisation (a 1.1) of at least one N-vinylamide, (a 1.2) vinyl acetate (a1.3), at least one polyether (a1.4) optionally at least one additional comonomer, (a2) at least one alkoxylate of general formula (I) , wherein variables assume following definitions: R¹ alkyl with 8-24 carbon atoms, linear or branched, R² alkyls with 1-10 carbon atoms, respectively, identical or different, linear or branched, or hydrogen atoms, R³ a hydrogen atom or alkyl with 1-4 carbon atoms, linear or branched, m from 1 to 100, in formulations (compositions) for automatic dish washing. Present invention also relates to a machine dishwashing method and to use of copolymer in formulations machine dishwashing.

EFFECT: technical result of present invention is obtaining compositions which can be used in agents for dish washing "X in 1", so that said agent can be added into main washing process, although good effect is observed only during rinsing.
