Embodiment 1

[0034] A multifunctional emulsion, comprising the following raw materials in parts by weight: 0.45 parts of vitamin E, 3.8 parts of glycerol, 3 parts of butanediol, 5 parts of castor oil, 80 parts of purified water, 1 part of hydrophilic nano-titanium dioxide powder and hydrophilic 0.5 parts of oil nano titanium dioxide powder.

[0035] The thus obtained multifunctional emulsion does not contain surfactants, which can effectively avoid skin allergy to surfactant components. And because the lotion contains sunscreen ingredients, it can physically block ultraviolet rays; at the same time, it contains vitamin E, an antioxidant ingredient, which can improve skin condition, effectively resist light skin photodamage, and help improve dull complexion. At the same time, it can also improve the stability and transdermal absorption efficiency of vitamin E in the emulsion, so as to facilitate the skin to absorb water and maintain a moist state.

Embodiment 2

[0037] A multifunctional emulsion, comprising the following raw materials in parts by weight: 0.5 parts of vitamin E, 4.5 parts of glycerol, 4 parts of butanediol, 7.5 parts of castor oil, 85 parts of purified water, 1.25 parts of hydrophilic nano-titanium dioxide powder and hydrophilic 0.75 parts of oil nano titanium dioxide powder.

[0038]The thus obtained multifunctional emulsion does not contain surfactants, which can effectively avoid skin allergy to surfactant components. And because the lotion contains sunscreen ingredients, it can physically block ultraviolet rays; at the same time, it contains vitamin E, an antioxidant ingredient, which can improve skin condition, effectively resist light skin photodamage, and help improve dull complexion. At the same time, it can also improve the stability and transdermal absorption efficiency of vitamin E in the emulsion, so as to facilitate the skin to absorb water and maintain a moist state.

Embodiment 3

[0040] A multifunctional emulsion, comprising the following raw materials in parts by weight: 0.55 parts of vitamin E, 5 parts of glycerol, 5 parts of butanediol, 9 parts of castor oil, 90 parts of purified water, 1.5 parts of hydrophilic nano-titanium dioxide powder and hydrophilic 0.9 parts of oil nano titanium dioxide powder.

[0041] The thus obtained multifunctional emulsion does not contain surfactants, which can effectively avoid skin allergy to surfactant components. And because the lotion contains sunscreen ingredients, it can physically block ultraviolet rays; at the same time, it contains vitamin E, an antioxidant ingredient, which can improve skin condition, effectively resist light skin photodamage, and help improve dull complexion. At the same time, it can also improve the stability and transdermal absorption efficiency of vitamin E in the emulsion, so as to facilitate the skin to absorb water and maintain a moist state.

Abstract

The invention relates to a multifunctional emulsion and a preparation method thereof. The multifunctional emulsion comprises, by weight, 0.45-1 part of vitamin E, 3.8-12.6 parts of glycerol, 3-10 parts of butanediol, 5-20 parts of castor oil, 80-120 parts of purified water, 1-4 parts of hydrophilic nano titanium dioxide powder and 0.5-2 parts of lipophilic nano titanium dioxide powder. The preparation method comprises the following steps that S101, the vitamin E, the castor oil, the hydrophilic nano titanium dioxide powder and the lipophilic nano titanium dioxide powder in the multifunctionalemulsion raw materials are evenly mixed for 15-25 minutes by an ultrasonic mixer to obtain a first mixture; S102, the glycerol, the butanediol and the purified water are added into the first mixture to obtain a second mixture; S103, the second mixture is dispersed at the rotating speed of 23000-25000 rpm for 3-7 minutes by using a high-speed dispersing machine; then the speed of the high-speed dispersing machine is adjusted to be 19000-21000 rpm, and the second mixture continues to be dispersed for 18-25 minutes to obtain the multifunctional emulsion. Therefore, the stability and transdermal absorption efficiency of the vitamin E in the emulsion can be improved.

Description

technical field [0001] The invention relates to the technical field of skin care products, in particular to a multifunctional emulsion and a preparation method thereof. Background technique [0002] Skin dehydration and oxidation will cause many skin problems, such as acne, wrinkles, stains, etc., and in severe cases, it will cause skin cancer. Therefore, skin hydration and anti-oxidation are the most basic functional demands of skin care products. At the same time, more and more studies have shown that ultraviolet rays in sunlight are also an important factor causing skin inflammation, immunosuppression, photoaging and even skin cancer. Ultraviolet radiation will cause a large number of various reactive oxygen species (ROS) including superoxide radicals, hydrogen peroxide, hydroxyl radicals and singlet oxygen, which will cause the above-mentioned various skin damage. Therefore, to combat skin problems, a multi-pronged approach of sun protection-antioxidation-hydration is ...
