The present invention describes a process for obtaining a biolubricant from vegetable oil, which comprises the steps of (a) esterification reaction of the product of vegetable oil hydrolysis using a branched aliphatic alcohol; (b) epoxidation reaction of the esters obtained in step (a); and (c) nucleophilic substitution reaction of the epoxidated esters obtained in step (b) using a branched aliphatic alcohol. The present invention also describes a biolubricant obtained from the process. More specifically, a biolubricant is described that is produced from a ricinoleic fatty acid, whose formula is illustrated in FIG. 1 of the present invention, and where R.sub.1 is a hydroxyl or it is from the formula R.sub.3COO.sup.−, with R.sub.3 being an alkyl radical C.sub.1-C.sub.3, preferably a methyl radical; and R.sub.2 consists of a straight chain of hydrocarbons C.sub.4-C.sub.8 and a branched chain of hydrocarbons C.sub.1-C.sub.3.
