A method of producing a two-phase agent containing lac of sulphur with the addition of resorcinol characterised in that three sets of components are prepared separately by rubbing: a set composed of 0.2-5 percent by weight of resorcinol and 0.01-0.5 percent by weight of nipagin P with 2-3 times as much of kaolin and a set composed of 0.1-3 percent by weight of iron pigments with 4-5 times as much of kaolin and a set composed of 2-15 percent by mass of lac of sulphur and 5-15 percent by mass of talc with the rest of kaolin which in total makes up 10-70 percent by mass of the substance, and further, the three sets are mixed, homogenized and 10-50 percent by mass of polyoxyethylene glycol 200 or polyoxyethylene glycol 400 or propylene glycol 1,2 or glycerol are added while mixing with a continual stream, and when a fully homogenous mixture is created, 10-30 percent by mass of emulsifying mixture are added, which is prepared by mixing 4-10 percent by mass of glycerol with 70-80 percent by mass of water and heating it to the temperature of 323-343 degrees K and adding 4-6 percent by mass of 10 percent aqueous solution of ammonia heated to that temperature, and further, 8-12 percent by mass of stearic acid is fused separately, also at the same temperature, and later it is heated to the temperature higher by 10 degrees K and further it is entered into a hot mixture of previously mixed components, and further mixed to produce a homogenous mixture until the emulsifying mixture has a temperature of 293-298 degrees K.
