A biodegradable lubricant which is prepared from: about 60-99 % by weight of at least one biodegradable synthetic ester base stock which comprises the reaction product of: a branched or linear alcohol having the general formula R(OH)n, wherein R is an aliphatic or cyclo-aliphatic group having from about 2 to 20 carbon atoms and n is at least 2; and at least one branched oxo acid having a carbon number in the range between about C5 to C10, provided that said branched oxo acid does not include 2-ethylhexanoic acid; wherein the ester base stock exhibits the following properties: at least 60 % biodegradation in 28 days as measured by the Modified Sturm test; a pour point of less than -25 °C; and a viscosity of less than 7500 cps at -25 °C, about 1 to 20 % by weight lubricant additive package; and about 0 to 20 % of a solvent.

Un lubrifiant biodégradable est préparé à partir de: environ 60-99 % en poids d'au moins un matériau de base biodégradable contenant un ester synthétique et consistant en un produit de réaction entre un alcohol ramifié ou linéaire ayant la formule générale R(OH)n, où R est un groupe aliphatique ou cyclo-aliphatique avec 2 à 20 atomes de carbone environ et n est au moins égal à 2, et au moins un oxo acide ramifié ayant un nombre de carbones compris entre environ C5 et C10, à condition que cet oxo acide ramifié ne comprenne pas l'acide 2-éthylhéxanoïque. Le matériau de base lubrifiant contenant l'ester synthétique présente les propriétés suivantes: une biodégradation d'au moins 60 % en 28 jours mesurée selon le test Sturm modifié; un point d'écoulement d'au moins -25 DEG C; et une viscosité d'au moins 7500 cps à -25 DEG C; de 1 à 20 % en poids environ d'un ensemble additif pour lubrifiant; et de 0 à 20 % environ d'un solvant.
