[0057] First, add oil-in-water emulsifier, polyol, and a small amount of first deionized water into the emulsification pot according to the mass ratio, mix evenly at 60-80°C, and cool to normal temperature to obtain the first mixed solution. Stir the first mixed solution continuously at a speed of 400-600 rpm, and slowly add the first oil phase to it dropwise, and stir until the emulsification is complete to obtain the second mixed solution, which is set aside.
[0058] Add co-stabilizers, thickeners, water-soluble preservatives, chelating agents and antioxidants sequentially into the second deionized water according to the mass ratio, and stir at 60-80°C at a speed of 100-500rpm until completely dissolved to obtain the fourth The mixed solution, wherein the thickener, preservative, chelating agent and antioxidant are conventional commercially available products, are not the object of protection of the present invention, as long as they meet the functional requirements.

Abstract
The invention provides a multiple emulsion composition, wherein the micelles formed by the oil-in-water emulsifier wrapping the first oil phase are dispersed in the water phase as the inner phase, and the micelles formed by the water-in-oil emulsifier wrapping the inner phase are dispersed in the second fat phase. The present invention also provides a preparation method of the emulsion, comprising: adding the mixed solution of the first oil phase and the oil-in-water emulsifier into the water phase to prepare the oil-in-water emulsion, and adding the oil-in-water emulsion as the inner phase to the oil-in-water emulsifier Type emulsifier and the mixed solution of the second fat phase, stir evenly, obtain multiple emulsion composition. The multiple emulsion composition provided by the present invention has a smaller emulsified particle size of the first oily phase, has high and low temperature stability in a wider temperature range, and can satisfy use and transportation in different environments. In addition, it avoids the greasy feeling of traditional water-in-oil emulsion and has a better refreshing, moist and moisturizing feeling for users, and has a broader application prospect in the field of daily chemicals.
Description
technical field [0001] The invention belongs to the technical field of cosmetics, and relates to an emulsion composition and a preparation method thereof, in particular to a multiple emulsion composition and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, consumers have higher and higher requirements for beauty and skin care products, which no longer meet the daily basic skin care needs, and more importantly, pursue a good sense of experience while satisfying skin care needs. At present, there are many brands and types of skin care cosmetics on the market. From the perspective of formula composition, oil-in-water and water-in-oil skin care products are the majority. [0003] Water-in-oil skin care products are composed of water phase, oil phase and water-in-oil emulsifier. The form of the system is to disperse water in the oil in the form of tiny droplets. The oil phase is the external phase or dispers...
