Lauric ester compositions
View Patent ↗Provided are compositions containing alkyl esters derived from triglyceride oils produced from genetically engineered microalgae. Specific embodiments relate to esters derived from oils with high C10-C12 fatty acid profile. Compositions comprising the esters include cleaning products, completion fluids, work-over fluids, drilling fluids, metal working fluids, lubricants, paints, and inks.
1. A cleaner comprising C1-C4 ester of fatty acids derived from triglyceride oil and at least one additional ingredient, the triglyceride oil produced by a microalga that is a recombinant oleaginous cell of the genus Prototheca , the oil having an altered fatty acid profile relative to an oil produced by a non-recombinant microalga of the genus Prototheca , the altered fatty acid profile having at least 10% C10:0 and 40% C12:0 fatty acids, the cleaner having a reduced odor compared to a cleaner where all the fatty acids are derived from vegetable or animal triglyceride oil having a fatty acid profile of at least 40% C12:0 fatty acids.
2. The cleaner of claim 1 , wherein the odor is an unpleasant odor characteristic of a C6 or C8 fatty acid or ester thereof.
3. The cleaner of claim 1 , wherein the ester is a methyl, ethyl, propyl, iso-propyl, butyl, or a tert-butyl ester.
4. The cleaner of claim 1 , having an altered fatty acid profile wherein C12:0>C10:0>C14:0.
5. The cleaner of claim 1 , wherein at least 50% of the fatty acids are C12:0 fatty acids or the combined total amount of C:10 and C:12 fatty acids is at least 60%.
6. The cleaner of claim 1 , wherein at least 15% of the fatty acids are C10:0 fatty acids.
7. The cleaner of claim 1 , wherein 15-25% of the fatty acids are C10:0 fatty acids.
8. The cleaner of claim 1 , wherein 10-15% of the fatty acids are C14:0 fatty acids.
9. The cleaner of claim 1 , wherein less than 8%, 7%, or 6% of the fatty acids are C16:0 fatty acids.
10. The cleaner of claim 1 , wherein less than 0.5% of the fatty acids are C8:0 fatty acids.
11. The cleaner of claim 1 , wherein less than 0.1%, 0.01%, or 0.001% of the fatty acids are C6:0 fatty acids.
12. The cleaner of claim 1 , comprising a terpene.
13. The cleaner of claim 1 , wherein the terpene is limonene.
14. The cleaner of claim 1 wherein the cleaner is an adhesive remover, a driveway cleaner, a degreaser, a graffiti remover, hand cleaner, a waterless hand cleaner, a paint brush cleaner, a paint stripper, a varnish remover, a rubber tire remover, a wipe, a bug remover, a tar remover, a car wash cleaner, a parts cleaner, an engine cleaner, a fuel system additive, a rig wash, a heavy residue cleaner, a down-hole cleaner, a concrete down-hole cleaner, an ink roller cleaner, a screen printing ink wash, or a cleaner for paints, inks, coatings, sealants, elastomers, or polymers.
15. A method for preparing a cleaner, the cleaner comprising C1-C4 esters of fatty acids derived from triglyceride oil, the triglyceride oil produced by a microalga that is a recombinant oleaginous cell of the genus Prototheca , the oil having an altered fatty acid profile relative to an oil produced by a non-recombinant microalga of the genus Prototheca , the altered fatty acid profile having at least 10% C10:0 and 40% C12:0 fatty acids, the cleaner having a reduced odor compared to a cleaner where all the fatty acids are derived from vegetable or animal triglyceride oil having a fatty acid profile of at least 40% C12:0 fatty acids, the method comprising the steps of:
a) providing the C1-C4 esters of fatty acids derived from the triglyceride oil;
b) admixing at least one additional ingredient with the C1-C4 ester of fatty acids derived from the triglyceride oil to prepare the cleaner.
16. The method of claim 15 , wherein the odor is an unpleasant odor characteristic of a C6 or C8 fatty acid or ester thereof.
17. The method of claim 15 , wherein the ester is a methyl, ethyl, propyl, iso-propyl, butyl, or a tert-butyl ester.
18. The method of claim 15 , wherein at least 50% of the fatty acids are C12:0 fatty acids or the combined total amount of C:10 and C:12 fatty acids is at least 60%.
19. The method of claim 15 , wherein at least 15% of the fatty acids are C10:0 fatty acids.
20. The method of claim 15 , comprising a terpene.
21. The method of claim 15 , wherein the terpene is limonene.
22. The cleaner of claim 1 , wherein the recombinant oleaginous cell is a Prototheca moriformis cell.
23. The method of claim 15 , wherein the recombinant oleaginous cell is a Prototheca moriformis cell.
