Abstract
A process for disposing of oil slicks on seawater comprises treating the polluted seawater with a liquid dispersing composition and a nitrogen-containing nutrient for the seawater micro-organisms which are active in oil metabolization. The nutrient is a diguanidinium salt having the general formula: EQU XH.H.sub.2 N--C(.dbd.NH)--NH--R--NH--C(.dbd.NH)--NH.sub.2 HX wherein R is preferably an alkyl radical containing from 2 to 12 carbon atoms and X is a halogen or an acid anion.
