Abstract
Abstract Composition useful in eliminating surface water pollution caused by crude petroleum oil or its fractions consisting of: 1. A CARRIER HAVING A SPECIFIC GRAVITY SUFFICIENTLY LOW THAT IT FLOATS (E.G. SAWDUST, SILICATES, DIATOMITE, VEGETABLE OIL RESIDUES, VEGETABLE FLOUR, ANIMAL FLOUR, SILICA GEL, CHARCOAL, POLYURETHANE RESIN AND POLYVINYL CHLORIDE); 2. A SURFACE ACTIVE AGENT, VIZ., SODIUM STEARATE, SODIUM ALKYLSULFONATE, POTASSIUM STEARATE, SODIUM DODECYLBENZENE-SULFONATE, POTASSIUM PALMITATE, NONYLPHENOL ETHYLENE OXIDE (1:7) OR TRIETHANOLAMINE OLEATE; AND 3. A WETTING AGENT, VIZ., ISOAMYL ALCOHOL, GLYCEROL, ETHYLENE GLYCOL, BUTYLIC ALCOHOL OR AMYL ALCOHOL.
