Problems solved by technology

At present, there are no patent reports on the preparation of nano-sized snake oil at home and abroad. Therefore, through the phospholipid coating technology, the snake oil is wrapped into a snake oil nano-microcapsule emulsion, thereby reducing the smell of snake oil and improving the stability of snake oil, which is beneficial to snake oil. Penetrates deep into the skin to give full play to the efficacy of snake oil

preparation example Construction

[0037] The preparation method of snake oil nano microcapsule emulsion of the present invention can be carried out as follows:

[0038] 1) Prepare a homogeneous mixed liquid A by mass percentage of 1-20% snake oil, 1-20% phospholipid and 1-20% surfactant at a temperature of 20°C-70°C and stirring conditions;

[0039] 2) Mix the above-mentioned mixed solution A with a dispersion medium with a mass percentage of 50-95% at a temperature of 20°C to 70°C under stirring conditions to prepare a homogeneous mixed solution B;

[0040] 3) Process the mixed solution B obtained in step 2) through a high-pressure homogenizer, the high-pressure homogenization pressure is 200bar to 1500bar, and the number of cycles is 2 to 20 times to obtain a transparent or translucent particle size less than 100nm Nano snake oil microcapsule emulsion.

[0041] In the above preparation method, the present invention can add 0.1-4% by mass percentage of fat-soluble antioxidant to the homogeneous mixture A, an...

Embodiment 1

[0044] Example 1 Weigh 2% phospholipids at 45°C and 50min -1 Stir with 1% black snake and Agkistrodon snake oil, 1% polyoxyethylene hydrogenated castor oil, 1% polyethylene glycol caprylic acid / capric glyceride and 0.2% vitamin E under the condition of rotating speed to form a uniform mixture, and then in 45℃ and 1800min -1 Mix the above-mentioned mixed solution with 94.8% aqueous solution containing 75% sorbitol under the condition of rotating speed, and continue to stir until a uniform emulsion is formed, and finally the emulsion is circulated through a high-pressure homogenizer for 18 times under the pressure of 200bar to obtain granules Transparent snake oil nano-microcapsule emulsion with diameter less than 100nm.

Embodiment 2

[0045] Example 2 Weigh 9% phospholipids at 40°C and 400min -1Stir with 9% Piper viper oil and 9% polyoxyethylene hydrogenated castor oil under rotating speed conditions to form a homogeneous mixture, and then heat at 25°C and 800min -1 Mix the above mixed solution with 3% vitamin C and 70% aqueous solution containing 75% glycerol under the condition of rotating speed, and continue to stir until a uniform emulsion is formed, and finally the emulsion is circulated through a high-pressure homogenizer for 3 times under the condition of 1500bar pressure , promptly obtain the transparent snake oil nano-microcapsule emulsion whose particle diameter is less than 100nm nanometer.

Abstract

The invention relates to a method for preparing snake oil nanometer micro capsule emulsion, wherein it is formed by snake oil, phosphatide, surface activator, oxidization resistance, and dispersing medium; the production comprises that: mixing phosphatide, snake oil and surface activator; mixing mixture with disperse medium; treating with high-pressure uniform machine. The average diameter is lower than 100nm, as transparent dense liquid; it has stable quality, to reduce smell; and it has high solubility, to be matched with cosmetic freely.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a snake oil nano-microcapsule emulsion and a preparation method thereof. Background technique [0002] Snake oil is refined and extracted from the fat of snakes in the snake family. Its application has a long history in my country. There are detailed records of snake oil in ancient books such as "Shen Nong Herbal Classic" in the Western Han Dynasty and "Compendium of Materia Medica" in the Ming Dynasty. Folks commonly use snake oil to treat frostbite, chapped, eczema and burns from water and fire. The main chemical components of snake oil are saturated fatty acids and unsaturated fatty acids, which have strong affinity and permeability to the skin. Snake oil is widely used in the treatment of various skin diseases and as an existing high-grade cosmetic for beauty and skin care (Tan Yujun et al., "Journal of Traditional Chinese Medicine", 1993, 34 (11): 691; Nobuya Shirai, "NutritionRese...
