Procedure to eliminate petroleum products by biological degradation, putting them in the form of small drops emulsifiable in water by adding to the petroleum products, before dispersion in water, a non-toxic and biodegradable emulsifier chosen from sodium oleylisothionate, sodium methylaminoethanesulfonate, sodium lauryl sulfate, sulphonated secondary paraffins, sulphonated alpha-olefins, sarcosinates, 2-amino-2-hydroxymethyl-1,3-propanediol, aminomethylpropanol, some etholated fatty alcohols and polyoxyethyloniglycol oleate, characterized in that prior to dispersion in water, is incorporated into the emulsifiable molecule made up of the petroleum product on which it is fixed, by its lipophilic radicals, the emulsifier that has free hydrophilic radicals, nitrogen and phosphorus, in the form of a phospho-amino lipid that enters the hydrocarbon solution .
