preparation example Construction

[0069] The present invention also provides a kind of preparation method of water-in-oil-in-water emulsion, comprising the following steps:

[0070] A) mixing the oil phase in the first preservative, the first emulsifier, the flavor modifier and the water-in-oil emulsion evenly to obtain a mixed oil phase;

[0071] heating and mixing the mixed oil phase and the water phase in the water-in-oil emulsion, and homogenizing to obtain the water-in-oil emulsion;

[0072] B) mixing deionized water, humectant, second emulsifier, stabilizer and carbomer resin, and homogenizing to obtain an aqueous phase;

[0073] C) Heat and mix the water-in-oil emulsion and the water phase, then add 1,3 dimethylol-5,5 dimethylhydantoin and 2-methyl-4-isothiazoline- 3-ketone, mixed and stirred to obtain a water-in-oil-in-water emulsion;

[0074] Step A) and step B) are not limited in order.

[0075] In the present invention, firstly, the first preservative, the first emulsifier, the flavor regulator a...

Abstract

The invention provides oil-in-water-in-oil emulsion. The oil-in-water-in-oil emulsion comprises an aqueous phase and water-in-oil emulsion which is uniformly dispersed in the aqueous phase, wherein the water-in-oil emulsion and the aqueous phase are in the mass ratio of 1:(0.5-2); the water-in-oil emulsion comprises a first emulsifying agent; the first emulsifying agent is selected from polyglycerin-3-diisostearate. According to a preparation method, the oil-in-water-in-oil emulsion is prepared by selecting and using a specific emulsifying agent; the prepared emulsion is stable and mild in performance; meanwhile, dual package of oil-in-water-in-oil is utilized; a skin moisturizing effect is achieved; lost oil content of skin is supplemented very well; a user feels fresh and cool after using the oil-in-water-in-oil emulsion, and an oily feel is avoided.

Description

[0001] This application claims the priority of the Chinese patent application submitted to the China Patent Office on January 04, 2016, the application number is 201610008033.X, and the invention title is "a water-in-oil-in-water emulsion and its preparation method", all of which The contents are incorporated by reference in this application. technical field [0002] The invention belongs to the technical field of skin care products, and in particular relates to a water-in-oil-in-water emulsion and a preparation method thereof. Background technique [0003] At present, there are two types of emulsification systems for emulsions used in cosmetic preparations on the market, one is oil-in-water emulsion and the other is water-in-oil emulsion. To ensure consumer acceptance of these two types of products, the key lies in the physicochemical properties of the emulsion. In addition, the stability of the emulsion and its ingredients is crucial to ensure the shelf life of these produ...
