Abstract

The present invention provides a fuel composition comprising: (a) a fuel; (b) polyglycerol polyricinoleic acid (c) a monoglyceride of a fatty acid.

Claims

         4 . A fuel composition according to any one of the preceding claims wherein the polyglycerol comprises one or a mixture of more than one of the polyglycerols selected from the group consisting of diglycerol, triglycerol, tetraglycerol, pentaglycerol, hexaglycerol, heptaglycerol, octaglycerol, nonaglycerol and decaglycerol. 
     
     
         5 . A fuel composition according to any one of the preceding claims wherein the fatty acid polymerised chain length of the polyricinoleic acid is from 1 to 10. 
     
     
         6 . A fuel composition according to any one of the preceding claims wherein the polyglycerol polyricinoleic acid is prepared from hydroxy fatty acids of hydrogenated or non-hydrogenated castor oil. 
     
     
         7 . A fuel composition according to any one of the preceding claims, wherein the polyglycerol polyricinoleic acid has a hydroxyl value of about 20 to about 120 mgKOH. 
     
     
         8 . A fuel composition according to any one of the preceding claims, wherein the monoglyceride of a fatty acid is monoglyceride of a fatty acid of a C16 to C22 fatty acid. 
     
     
         9 . A fuel composition according to  claim 8 , wherein the monoglyceride of a fatty acid is monoglyceride of a C16 or C18 fatty acid. 
     
     
         10 . A fuel composition according to any one of the preceding claims, wherein the monoglyceride of a fatty acid is monoglyceride of unsaturated fatty acid. 
     
     
         11 . A fuel composition according to any one of the preceding claims, wherein the monoglyceride of a fatty acid is monoglyceride of mono or di unsaturated fatty acid. 
     
     
         12 . A fuel composition according to any one of the preceding claims, wherein the monoglyceride of a fatty acid is a mixture of
 1) monoglyceride of saturated C16 fatty acid   2) monoglyceride of saturated C18 fatty acid   3) monoglyceride of mono unsaturated C18 fatty acid; and   4) monoglyceride of di unsaturated C18 fatty acid.   
     
     
         13 . A fuel composition according to any one of the preceding claims, wherein the monoglyceride of a fatty acid is a mixture of
 1) palmitic acid monoglyceride   2) stearic acid monoglyceride   3) oleic acid monoglyceride; and   4) linoleic acid monoglyceride.   
     
     
         14 . A fuel composition according to any one of the preceding claims, wherein the ratio of (b) polyglycerol polyricinoleic acid to (c) a monoglyceride of a fatty acid is from 0.7:0.3 to 0.1:0.9. 
     
     
         15 . A fuel composition according to any one of the preceding claims, wherein the ratio of (b) polyglycerol polyricinoleic acid to (c) a monoglyceride of a fatty acid is from 0.625:0.375 to 0.125:0.875. 
     
     
         16 . A fuel composition according to any one of the preceding claims, wherein the fuel composition comprises (b) polyglycerol polyricinoleic acid and (c) a monoglyceride of a fatty acid in a total combined amount of from 0.1 to 2.0 wt % based on the total fuel composition. 
     
     
         17 . A fuel composition according to any one of the preceding claims, wherein the fuel composition comprises (b) polyglycerol polyricinoleic acid and (c) a monoglyceride of a fatty acid in a total combined amount of from 0.1 to 1.0 wt % based on the total fuel composition.
