Abstract: The invention discloses oil congealing compositions to coagulate oil that has been spilled on water. The congealing composition is oliophilic based and floats on the water surface to contract and congeal oil spills in both salt and fresh water, which includes in significant amounts a polypropylene glycol ether, an alcohol, an ester and polyoxyalkyl glycol ether. After the congealing composition is applied to the oil spill, the floating congealed oil can be readily mechanically removed from the water such that at least 99.9% of the oil is removable from the water with minimal negative environmental impact.
