Abstract

The process for disposing of oil slicks on seawater consists in treating the polluted seawater with a liquid dispersing composition and with a nitrogen-containing nutrient for the micro-organisms which are active in oil metabolism. The nutrient is a diguanidinium salt XH.H2N - C(=NH) - NH - R - NH - C (NH) - NH2.HX wherein R is an alkyl radical containing from 2 to 12 carbon atoms and X is a halogen or an acid anion.
