Problems solved by technology

At present, there are usually four methods for preparing fine emulsions, which are emulsifier in water method, phase transition temperature method, inverse emulsification method, and D-phase emulsification method. Although it is more environmentally friendly than traditional emulsion preparation, the preparation process also requires heating. , temperature control, homogenization, stirring, and the above method can only be used for O / W type fine emulsion

Abstract

The invention provides a preparation method of W / O type mini emulsion, and aims to provide a preparation method of water-in-oil type emulsion which can realize emulsifying under normal temperature without consuming too much energy, can spontaneously and quickly form an emulsifying body, and is stable in emulsifying system and small in particle diameter. The preparation method comprises the steps of (1) uniformly mixing and stirring a polyether modified organic silicon emulsifying agent, monohydric alcohol monohydric alcohol dihydroxy alcohol and a hydrating agent to obtain a mixture; (2) adding fat, a thickening agent and the monohydric alcohol to an emulsifying pot, performing uniform stirring, and performing homogenizing to obtain a second mixture; (3) adding aqueous phase components tothe aqueous phase pot, performing stirring, performing heating to 75-80 DEG C, performing heat-insulating dissolving, and performing stirring to lower the temperature to 40 DEG C or below for standbyapplication to obtain a third mixture; and (4) adding a co-emulsifier and the first mixture to the emulsifying pot, performing uniform mixing with the second mixture, then adding the third mixture inthe emulsifying pot, performing uniform stirring, and performing low-speed homogenizing and emulsifying so as to obtain the W / O type mini emulsion. The invention belongs to the technical field of skincare products.

Description

technical field [0001] The invention discloses a method for preparing an emulsion, in particular a method for preparing a W / O microemulsion, and belongs to the technical field of skin care products. Background technique [0002] The preparation method of the traditional cosmetic emulsion is to heat the water phase and the oil phase separately in advance, and then mix the two with a homogenizer to disperse evenly, stir and cool to room temperature, and usually add one or more emulsifiers to the formula to prevent milky liquid In the case of oil-water separation, it takes a lot of time and energy to heat the oil phase and water phase to 70°C or above, and it takes more time and energy to cool the paste to room temperature. [0003] The preparation of cosmetics by cold blending process can be realized by selecting a suitable cold blending emulsifier. Its cost saving is more and more popular among cosmetics manufacturers. The preparation of cosmetics at room temperature also has...
