Japanese Patent JPH03504685
Kind Code:

Abstract:
Low viscosity oil-in-water emulsions of oil components, comprising 50-100 wt.% of mono- and diesters with at least 10 C atoms and possibly 0-50 wt.% of fatty acid triglycerides and/or 0-25 wt.% of hydrocarbon oils, are prepared by emulsifying foregoing substances with 0.1-0.5 parts by weight of an emulsifier with an HLB value of 11-22 and preferably 0.1-0.5 parts by weight, referred to 1 part by weight of the oil component, of a co-emulsifier of the saturated fatty alcohol or fatty acid-polyol partial ester type at a temperature above the melting point of the mixture of oil component, emulsifier and co-emulsifier with at least 1 part by weight of water, referred to 1 part by weight of the oil component. The emulsion is then heated to a temperature within or above the phase inversion temperature range. Alternatively, the emulsion is produced at this temperature and then cooled to a temperature below the phase inversion temperature range and further diluted with water, if necessary.
