U.S. Polychemical Corp said that currently the oil spill in the Gulf of Mexico is being contained by the use of a chemical solvent that is potentially harmful to wild life. According to Polychem, its product, Dispersit, a water-based surfactant product used to clean up oil spills, has shown a significant reduction in the harm caused to both human and aquatic life. Dispersant products formulated with petroleum mineral spirits used as dilutents can be potentially harmful, the company claims. However, Polychem’s Dispersit is a blend of water, water-soluble surfactants and a coupling co-solvent.
