FIELD: chemistry.
SUBSTANCE: invention relates to synthetic detergents. Composition of synthetic detergents based on synthetic surfactants contains homologues C14, C13, C12 with biodegradability Tind of not more than 6 days and complete biodegradability XTindcom at time Tind is more than 85% in the following ratio (wt.%): C14 – 70±3; C13 – 22±3; C11 and below – 0–0.5; C12 is the rest.
EFFECT: invention provides prevention of water pollution by waste water containing synthetic surfactants.
