Dispersant for spilled oil
A method for dispersing oil spilled into the aqueous environment comprising the treatment of the spilled oil with an oil dispersant composition comprising a phospholipid and a polysaccharide derivative is disclosed.
1. A method for preventing a deposition onto a solid hydrophobic substrate by oil spilled in seawater without wetting the solid hydrophobic substrate comprising applying to the spilled oil a composition comprising one or more lecithins and one or more cellulose ethers selected from the group consisting of hydroxypropylcellulose, hydroxypropylmethylcellulose, and combinations thereof.
2. The method of claim 1 wherein said applying to the spilled oil is performed by an application selected from the group consisting of spraying, spreading, and pumping said composition into an area of the spilled oil.
3. The method of claim 1 wherein said one or more lecithins are of plant origin.
4. The method of claim 3 wherein said one or more lecithins is soy lecithin.
5. The method of claim 1 wherein the solid hydrophobic substrate comprises a surface of a living creature.
6. The method of claim 5 wherein the surface comprises feathers.
7. The method of claim 5 wherein the surface comprises hair.
8. The method of claim 5 wherein the surface comprises plants.
9. A method of mitigating spreading of spilled oil from seawater to a solid hydrophobic substrate without wetting the solid hydrophobic substrate comprising applying to the spilled oil a composition comprising a phospholipid selected from the group consisting of a lecithin and a lecithin derivative and combinations thereof, and at least one cellulose ether selected from the group consisting of hydroxypropylcellulose, hydroxypropylmethylcellulose, and combinations thereof.
10. The method of claim 9 wherein said phospholipid is a lecithin.
11. The method of claim 10 wherein said lecithin is of plant origin.
12. The method of claim 11 wherein said lecithin is soy lecithin.
13. The method of claim 9 wherein said applying to the spilled oil is performed by an application selected from the group consisting of spraying, spreading, and pumping said composition into an area of the spilled oil.
14. The method of claim 9 wherein the solid hydrophobic substrate comprises a surface of a living creature.
15. The method of claim 14 wherein the surface comprises feathers.
16. The method of claim 14 wherein the surface comprises hair.
17. The method of claim 14 wherein the surface comprises plants.
