preparation example Construction

[0035] The preparation method of the present invention is as follows:

[0036] 1) 100 parts by weight of emu oil, 65 to 150 parts by weight of phospholipids and 35 to 100 parts by weight of stabilizer are mixed at a temperature of 25°C to 60°C under stirring conditions until a uniform mixture is formed;

[0037] 2) The above mixed solution is mixed with 85-500 parts by weight of glycerin and 170-650 parts by weight of deionized water at a temperature of 25° C. to 60° C. under stirring conditions to prepare emu oil colostrum.

[0038] 3) The emu oil primary emulsion obtained in step 2) is processed by mature high-pressure homogenizer technology, the high-pressure homogenization pressure is 500bar~1500bar, and the number of cycles is 3~18 times, and the nano emu oil can be obtained Concentrated lotion.

[0039] 7. according to the method for the nanometer emu oil concentrated emulsion of claim 6, it is characterized in that: in described step 1), add the vitamin E of 8~30 weigh...

Embodiment 1

[0045] 1. Weigh 65g of phospholipids (PC content ≈ 72%) and stir with 100g of emu oil and 50g of polyoxyethylene 40 hydrogenated castor oil at 60°C and 200rpm to form a homogeneous mixture.

[0046] 2. Mix the above mixed solution with 200g glycerin and 450g deionized water at 60°C and 1800rpm, and continue to stir until a uniform emulsion is formed.

[0047] 3. Finally, the above-mentioned emulsion was processed through a high-pressure homogenizer for 5 cycles under a pressure of 800 bar to obtain a transparent nano emu oil concentrated emulsion.

Embodiment 2

[0049] 1. Weigh 100g of phospholipids (PC content ≈ 72%) and stir with 100g of emu oil and 35g of polyoxyethylene 20 sorbitan monooleate at 55°C and 400rpm to form a uniform mixture.

[0050] 2. Mix the above mixture with 500g glycerin and 650g deionized water at 50°C and 1800rpm, and continue to stir until a uniform emulsion is formed.

[0051] 3. Finally, the above-mentioned emulsion is processed through a high-pressure homogenizer cycle for 4 times under a pressure of 1000 bar to obtain a transparent nano emu oil concentrated emulsion.

Abstract

The invention provides a condensed milk liquid which is prepared from emu oil 100 parts, phospholipids 65-150 parts, stabilizer 35-100 parts, glycerine 85-500 parts and balancing deionized water through steps of mixing homogeneously and heavy pressure homogeneous circulating.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to a concentrated emu oil emulsion of nanometer. Background technique [0002] Emu bird originated from Europe. Emu oil is extracted from emu retroperitoneal and subcutaneous adipose tissue. It has a fatty acid composition very similar to human skin oil. Unsaturated fatty acids in emu oil account for about 70%, of which Contains two essential fatty acids, linoleic acid and alpha-linolenic acid. According to reports, emu oil has anti-inflammatory and analgesic effects, smoothing wrinkles, removing dead skin, moisturizing, anti-oxidation, anti-aging, and anti-ultraviolet rays. [0003] Due to the very high content of unsaturated fatty acids in emu oil, it is prone to oxidative rancidity and instability during storage, so that it loses the effect of emu oil. With the wide application of nanotechnology in the field of cosmetics, the cosmetics developed by nanotechnology ...
