[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 multi-emulsion composition. An oil-in-water type emulsifier covers micelle formed by a first grease phase and is dispersed in a water phase to be used as an inner phase; and a water-in-oil type emulsifier covers micelle formed by the inner phase and is dispersed in a second grease phase. The invention further provides a preparation method of emulsion. The preparation method comprises the following steps: adding a mixed solution of the first grease phase and the oil-in-water type emulsifier into the water phase to prepare oil-in-water emulsion; by taking the oil-in-water emulsion as the inner phase, adding the inner phase into a mixed solution containing the water-in-oil type emulsifier and the second grease phase; and stirring uniformly to obtain the multi-emulsion composition. According to the multi-emulsion composition provided by the invention, the first grease phase has a smaller emulsification grain diameter and has high and low temperature stability in a wider temperature range, and can be used and transported under different environments. Furthermore, the greasy feeling of traditional oil-in-water emulsion is avoided and a user has better fresh and cool feeling, moisture feeling and nourishing feeling and has a wider 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...
