Abstract
Present invention relates to a process for manufacturing emulsion composition which comprises an oil phase dispersed in a continuous water phase which is stabilized with a surfactant as an emulsifier. The present invention is on a method for producing an emulsion comprising one or more fatty alcohol, one or more oil liquid at 20° C. and one or more surfactant wherein one or more surfactant is added to the dispersion of one or more fatty alcohol and one or more oil liquid at 20° C. in water at a temperature of 50° C. or higher, preferably 60° C. or higher with the condition that the temperature of the dispersion is at least 10° C. higher than the melting point of fatty alcohol having the highest melting point, more preferably between 60 and 85° C. wherein the emulsion thus obtained does not comprise dispersed droplets with a volume size larger than or equal to 10 μm measured directly without dilution of the emulsion at 20° C. measured with a laser particle size analyzer suitable therefore.
