<p>1. Cleaning agents for dispersing hydrocarbon compounds in a marine environment, characterized in that they comprise a mixture of two types of phosphoric acid triesters, namely : the triesters of the formula : see diagramm : EP0010012,P8,F1 and the triesters of the formula : see diagramm : EP0010012,P9,F2 in which : R represents a linear or slightly branched alcohol or acid containing from 6 to 20 carbon atoms. A represents : a mixture of ethoxy and propoxy groups, in which the ratio of the number of ethoxy groups to propoxy groups is less than 2, and in which the number of propoxy groups is less than 10 ; 1 to 4 ethoxy groups when the number of carbons in R is less than 12 ; 1 to 10 ethoxy groups when the number of carbons in R is 12 to 15 ; or 1 to 15 ethoxy groups when the number of carbons in R is 16 to 20, B represents : a group see diagramm : EP0010012,P9,F3 in which R' is a hydrogen or a methyl radical or ethyl radical, and x, y and z have a value from 1 to 4, (x+y+)z/3 being greater than 1.</p> |
