FIELD: chemistry.
SUBSTANCE: invention relates to an organoclay-based composition, a thixotropic composition which contains an organoclay-based composition and a method for producing a substantially constant rheological profile of an oil-based drilling mud. Organoclay-based composition includes phyllosilicate clay which is exchanged with quaternary ammonium ions of formula [NR1R2R3R4]+, in which at least one of R1, R2 and R3 is a mixture of branched alkyl groups.
EFFECT: invention enables to obtain a modified organoclay widely used in various compositions, for example paints, for coatings, in drilling fluids as an additive which improves rheological properties thereof.
