Problems solved by technology

[0002] The traditional cosmetic emulsification process often uses physical, chemical and mechanical methods to prepare O / W or W / O emulsions, but due to the different polarity of the water-oil system, such emulsions often show low heat-resistant or cold-resistant stability
For example: the emulsification particles produced by the phase inversion emulsification method are large, which makes the product easy to layer; the HLB temperature emulsification method is extremely sensitive to temperature and water-oil ratio, and it is difficult to obtain a clear and transparent material body when used in makeup water; the gel emulsification method The scope of application is limited and it is difficult to be widely used; the liquid crystal emulsification method has strict requirements on surfactants in order to form the required microcrystalline phase
[0003] Transparent or translucent nano-microemulsion composition is a type of composition with a particle size between 10 and 100nm. Due to the high content of surfactants in the previous formulations and the safety and stickiness of the product, etc. problems, so that it has not been widely used in cosmetics

Abstract

The invention discloses a nanometer micro-emulsion composition, preparation thereof and application of the nanometer micro-emulsion composition to a cosmetic. The nanometer micro-emulsion composition is mainly prepared from a main surfactant, an oil phase component, glycerinum and an aqueous phase component, wherein the main surfactant is at least one of poly(propylene glycol) fatty acid ester, hydrogenated castor oil and polyglycerol fatty acid ester, the oil phase component is at least one of macadamia oil, jojoba oil, isohexadecane and olive oil, and the aqueous phase component is deionized water. The nanometer micro-emulsion composition is smaller in particle diameter, uniform in particle size, better in stability and low in layering possibility, a preparation method is simple, and technological parameters are relatively flexible and can be correspondingly adjusted according to material difference; besides, the nanometer micro-emulsion composition is used in the cosmetic field, can obviously improve the use feeling of the cosmetic, light skin-touch is realized, the cosmetic is extremely easy to absorb by the skin, and the stability of the cosmetic can be improved.
