FIELD: oil refining industry. SUBSTANCE: invention makes it possible to increase separating ability of the composition due to improved spreadability of the latter over the surface of petroleum product and lower adhesion to metallic surface and increased electrical conduction. The composition comprises polyacrylamide, sodium sulfoethoxylate, chromium potassium alum, potassium bichromate and water, the ratio of ingredients being as follows (wt %): 1.020-1.120 polyacrylamide; 0.350-0.500 sodium sulfoethoxylate; 0.940-0948 potassium bichromate; 0.070-0.200 chromium- potassium alum, and water, the balance. EFFECT: improved properties of the composition. 5 tbl
