The present invention relates to a composition and method for inhibiting the formation of naphthenate solids in a liquid hydrocarbon. The method includes contacting a composition including a rosin amine having a formula (I): or (II): where formula (AA): represents a single or double bond; R1, R2 and R5 each independently represent H, alkyl, alkenyl or an alkynyl group each having between one and ten carbon atoms, —(R3O)nR4 wherein R3 is an alkyl group having 1 to 3 carbon atoms and R4 is H, alkyl, alkenyl or an alkynyl group each having between one and ten carbon atoms; n is an integer between 5 and 50; X is a halide, sulphate, phosphate or acetate ion; and a demulsifier intermediate with the liquid hydrocarbon.

1. A composition for inhibiting the formation of naphthenate solids from liquid hydrocarbon, the composition including a rosin amine having formula: where represents a single or double bond; R1, R2 and R5 each independently represent H, alkyl, alkenyl or an alkynyl group each having between one and ten carbon atoms, —(R3O)nR4 wherein R3 is an alkyl group having 1 to 3 carbon atoms and R4 is H, alkyl, alkenyl or an alkynyl group each having between one and ten carbon atoms; n is an integer between 5 and 50; X is a halide, sulphate, phosphate or acetate ion; and a demulsifier intermediate, the composition further including at least one of: a glycol selected from monoethylene glycol, diethylene glycol, triethylene glycol, propylene glycol and butylene glycol, and at least one hydrocarbon solvent selected from hexane, heptane, toluene, xylene, mesitylene and mixtures thereof. 2. The composition of claim 1, wherein R1, R2 and R5 are H. 3. The composition of claim 2, wherein the rosin amine is 1,4a-dimethyl-7-isopropyl-1,2,3,4,4a,9,10,10a-octahydro-1-phenanthrenemethylamine. 4. The composition of claim 1, wherein at least one of R1, R2 or R5 is —(R3O)nR4 and R3 has two carbon atoms. 5. The composition of claim 4, wherein n is an integer between 9 and 16. 6. The composition of any one of claim 1, wherein the rosin amine is an ethoxylated derivative of 1,4a-dimethyl-7-isopropyl-1,2,3,4,4a,9,10,10a-octahydro-1-phenanthrenemethylamine. 7. The composition of claim 6, wherein the ethoxylated derivative contains between about 5 to 50 ethoxyl groups. 8. The composition of claim 1, wherein the rosin amine is present in the amount of up to about 50% w/w. 9. The composition of claim 1, wherein the demulsifier intermediate is selected from esters, polyglycol esters and ethers, oxalkylated resins with low or high oxide content, sulphonates polymerised oils and esters, alkanolamine condensation products, oxyalkylated phenols, oxyalkylated polyamines, polymerised polyglycols and oxyalkylated polyglycols, preferably the group consisting of D-51, D-601, and Duomeen CD. 10. The composition of claim 1, further including at least one alcohol. 11. The composition of claim 10, wherein the at least one alcohol is selected from the group consisting of methanol, ethanol, propanol and isopropanol. 12. The composition of claim 10, wherein the at least one alcohol is present in the amount between about 5% and 80. 13. The composition of claim 1, further including at least one acid. 14. The composition of claim 13, wherein the at least one acid is selected from the group consisting of sulphuric acid, hydrochloric acid, phosphoric acid, acetic acid, propanoic acid, benzoic acid, benzene sulphonic acid, dodecyl benzene sulphonic acid and isopropylamine dodecyl benzene sulphonic acid. 15.

The composition of claim 13, wherein the composition includes at least one acid and at least one alcohol. 17. The composition of claim 1, further including at least one hydrocarbon solvent including high and low flash and mutual solvents. 18. A method for inhibiting the formation of naphthenate solids in a liquid hydrocarbon including contacting a composition including a rosin amine having a formula: where represents a single or double bond; R1, R2 and R5 each independently represent H, alkyl, alkenyl or an alkynyl group each having between, one and ten carbon atoms, —(R3O)nR4 wherein R3 is an alkyl group having 1 to 3 carbon atoms and R4 is H, alkyl, alkenyl or an alkynyl group each having between one and ten carbon atoms; n is an integer between 5 and 50; X is a halide, sulphate, phosphate or acetate ion; and a demulsifier intermediate; the composition further including at least one of: one or more glycols selected from monoethylene glycol, diethylene glycol, triethylene glycol, propylene glycol and butylene glycol, and a hydrocarbon solvent selected from hexane, heptane, toluene, xylene, mesitylene and mixtures thereof. 19. The method of claim 18, wherein the rosin amine is 1,4a-dimethyl-7-isopropyl-1,2,3,4,4a,9,10,10a-octahydro-1-phenanthrenemethylamine or an ethoxylated derivative thereof. 20. The method of claim 18, wherein the composition is added to the liquid hydrocarbon in an amount of up to about 1000ppm. 21.
