Problems solved by technology

These emu oil-containing liposomes or emulsions used in cosmetics in the prior art need to be repeatedly homogenized by a high-pressure homogenizer during the preparation process. This homogeneous product is placed in the process or added to cosmetics. It is easy to cause instability due to environmental changes, especially difficult to apply to non-emulsified water-based systems, especially transparent systems such as lotion, skin care gel, transparent shampoo and various hair care styling products

Embodiment 1

[0035] Embodiment 1, adopt surfactant, mixed oil and water of different proportions to prepare microemulsion

[0036] Using surfactant PPG-5-ceteth-20 (abbreviated as AWS) and oleth-3 phosphate (abbreviated as O3A), the mixing mass ratio of the two is 2:1;

[0037] The compound oil uses emu oil, avocado oil, tea tree oil and vitamin E, and the mixing mass ratio of the four is: 1.0:1.0:0.5:0.3;

[0038] Take AWS+O3A as one phase; set the quality of the mixed grease as 1g, according to m(oil phase) / m(AWS+O3A)=1 / 9, 1 / 8, 1 / 7, 1 / 6, 1 / 5 , 1 / 4, 1 / 3, 1 / 2, 1 / 1 Calculate the quality of the surfactant, the amount of water added is the minimum amount for the system to be a uniform fluid, see the table below for details:

[0039]

[0040] Conclusion: According to the test results, when the ratio of AWS+O3A to mixed oil is greater than 3:1, a uniform transparent to translucent microemulsion system can be obtained by adjusting the amount of water added. The ratio of compound oil, surfac...

Abstract

The invention provides a compound grease microemulsion used in cosmetics and a preparation method thereof. The microemulsion is prepared by raw materials including compound grease, a surfactant and water, wherein the weight ratio of the compound grease, the surfactant and the water is 1:3-10:20-100; and the compound grease is a mixture of emu oil, mimusops elengi tree fruit oil, tea tree oil and vitamin E. The compound grease microemulsion is transparent or translucent in appearance, the average particle size is less than 100nm, the stability of the grease is enhanced, the compatibility of the grease with water-soluble substances is improved, and the compound grease microemulsion can be used in various skin care products and cleaning and nursing supplies, and is especially applicable to products in a transparent system.

Description

technical field [0001] The present invention relates to a microemulsion and a preparation method thereof, in particular to a composite oil microemulsion for cosmetics and a preparation method thereof, wherein said composite oil comprises emu oil, shea butter oil and tea tree oil , further including vitamin E. Background technique [0002] Microemulsion is a thermodynamically stable system with clear, transparent or translucent appearance and low viscosity formed spontaneously by water, oil and surfactant in an appropriate proportion. The particle size is between 1nm and 100nm and is isotropic. A thermodynamically stable oil / water / emulsifier dispersion. The stability of microemulsion system will be affected by factors such as oil phase, temperature, pH value and surfactant. Among them, the choice of surfactant is closely related to the type, nature and purpose of use of microemulsion products. [0003] At present, the application of microemulsions in various cosmetics is m...
