FIELD: dispersants.
SUBSTANCE: invention relates to dispersants based on surfactants intended for elimination of emergency oil spills by dispersing a floating oil film. The invention relates to a dispersant for an oil spill response. The dispersant contains the following components: polyoxyethylene sorbitan monooleate - 20-30 wt. %, sodium dioctyl sulfosuccinate - 10-30 wt. %, sorbitan monooleate - 10-20 wt. %, the solvent - the rest. The solvent consists of a mixture of water and C3-C5 glycol: propylene glycol, butylene glycol, pentylene glycol. The solvent is made in accordance with the glycol-water ratio of 40-60: 60-40 wt. %.
EFFECT: invention constitutes a dispersant with low toxicity, higher biodegradability, a low freezing point, which will make it possible to use it also in the Arctic conditions, with greater efficiency of dispersion at different oil densities, at different temperatures, at different water salinity.
