Problems solved by technology

[0003] In the existing method of preparing microemulsion, it is necessary to add a large amount of surfactant to obtain a stable microemulsion, but the microemulsion prepared by this method is very irritating, which limits its application
There are also manufacturers using special equipment to prepare microemulsions, but the high cost of this process also limits its application

Embodiment Construction

[0021] The implementation of the present invention will be illustrated by specific specific examples below, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0022] A microemulsion comprises the following components in parts by weight: 35-77 parts of water, 2-4 parts of emulsifier, 15-50 parts of organic solvent and 0.5-1 part of arbutin.

[0023] In the field of daily chemicals, water, emulsifier and organic solvent are mixed. Based on the properties of both hydrophilic and lipophilic emulsifiers, the three can form a stable emulsion system after high-speed stirring, and the dispersion is relatively uniform, but not transparent; In order to obtain a transparent microemulsion system, it is necessary to increase the amount of emulsifier. However, as the amount of emulsifier increases, the irritation increases and the scope of use is limited.

[0024] Wherein, the emulsif...

Abstract

The invention discloses a microemulsion and a preparation method thereof. The microemulsion comprises the following components in parts by weight: 35-77 parts of water, 2-4 parts of an emulsifying agent, 15-50 parts of an organic solvent and 0.5-1 part of arbutin. The transparent microemulsion is obtained through compounding of the water, the emulsifying agent, the organic solvent and the arbutin.The addition dosage of surfactants to the microemulsion disclosed by the invention is small, so that the microemulsion is small in irritation. The microemulsion disclosed by the invention is good instability.

Description

technical field [0001] The invention relates to the technical field of daily chemicals, in particular to a microemulsion and a preparation method thereof. Background technique [0002] If two or more immiscible liquids are mixed and emulsified, and the diameter of the dispersed droplets is between 5nm and 100nm, the system is called a microemulsion. Microemulsion is a transparent dispersion system, and its formation is related to the solubilization of micelles. It is also called "swollen micellar solution" or "micelle emulsion", referred to as microemulsion. Microemulsions are usually transparent or translucent liquid stable systems composed of oil, water, surfactants, co-surfactants, and electrolytes. Microemulsion, which is characterized in that the particle size of the dispersed phase is between 0.01 and 0.1 μm, the size of the particle is uniform, and is invisible to the microscope; the particle is spherical; the microemulsion is translucent or transparent, and the ther...
