Dispersants are a common product used to clean and control oil spills in the ocean.
They are special fluid chemicals that bond to the oil molecules and separate them from water molecules, thus breaking up the oil. The result is tiny oil droplets that can biodegrade more quickly than a mass of oil.

How are dispersants used?
Dispersants are usually used on the surface of the ocean and distributed by aircraft flying over an oil spill. BP said it had made more than 120 such flights to spread dispersant every week when in the Gulf of Mexico.
Using it underwater is a new idea, and BP says it hopes to inject the dispersants directly into the oil flow at a point close to the main leak on the seabed. The technique could help break up and disperse the oil before it reaches the surface, BP says.

This product is widely used in seas, harbor, wharf, on which occasions the spilt oil need to be dealt with. The product is specially suitable for open seas, and occasions when the sea sea condition is worse and unable to recycle the spilt oil, or hard to recycle due to the thinness of the spilt oil. The range of the stickiness of this product is between 0 and 10000 Celsius temperature, suitable for spray spilt oil of middle and low - level stickiness.
