NATURAL EMULSION AND PRODUCTION METHOD THEREOF

摘要

The invention relates to a method for producing a natural emulsion, comprising the following steps, during a first phase: a) a fatty substance is selected and introduced into a reactor in the presence of an alkaline agent diluted in a sufficient quantity of water, according to the saponification index of said fatty substance, in order to achieve the hydrolysis of the fatty substance and to salify the free fatty acids formed, and b) the temperature of the reactor is increased to between 60 and 100°C, and the mixture is stirred until a homogeneous paste is obtained; and during a second phase carried out continuously from the preceding steps: c) an oily phase and an aqueous phase that have been previously heated to a temperature of between 70 and 80°C are added in varying proportions according to the desired type of emulsion; d) the mixture obtained from the preceding steps is stirred, then the temperature of the reactor is lowered until the reactor is fully cooled, in order to obtain a homogeneous emulsion. The invention also relates to a natural emulsion obtained according to the method of the invention, and to the use thereof in the cosmetic and pharmaceutical fields, or in the agro-food industry.
