Claim 13:
14. A process for the preparation of the corrosion inhibitor formulation as claimed in claim 1, the process comprising:
a) obtaining the at least one quaternary ammonium salt in a range of 10-50 weight % with respect to the formulation;
b) obtaining the at least one fatty acid methyl ester in a range of 10-50 weight % with respect to the formulation;
c) obtaining the at least one viscosity reducing agent in a range of 0-5.0 weight % with respect to the formulation;
d) obtaining the at least one solubilizing agent in a range of 0.3-3 weight % with respect to the formulation; and
e) contacting the at least one quaternary ammonium salt, the at least one fatty acid methyl ester, the at least one solubilizing agent, and the at least one viscosity reducing agent to obtain the corrosion inhibitor formulation.
