FIELD: wood impregnation composition, in particular, composition for wooden sleepers or bars. SUBSTANCE: antiseptic comprises wide stabilized oily fraction of heavy catalytic cracking gas oil boiling out at temperature within the range of 200-500 C, and alleviated thermal cracking remainder boiling out at temperature within the range of 200-540 C, which serves antiseptic chilling temperature regulator. Predetermined component ratio provides wide chilling temperature range of from 2 C to -35 C. EFFECT: increased operating life of oily antiseptics for wood impregnation by useful employment of gas oil fractions and heavy petroleum remainders of petroleum secondary processing operations. 10 ex
