Process for obtaining high viscosity and low freezing sterol, characterized in that branched aliphatic polyols are reacted with 2 to 6 primary hydroxyl groups, with saturated, branched, aliphatic, monocarboxylic acids, with a total of 14 to 22 carbon atoms. Carbon, in the presence of an esterification catalyst, such as tin powder, aluminum powder, zinc dust and p-toluenesulfonic acid, or partial mixtures of these compounds, at a temperature between 150 and 250ºC and under a pressure between the atmospheric pressure and approximately 20 torr, for a period of time comprised between one and five hours approximately.
