Embodiment 1～9

[0024] Embodiment 1~9: preparation 100gTiO 2 Sunscreen nanoemulsion. Take 20g of distilled water to swell and dissolve Carbomer 980 to obtain a Carbomer 980 solution with a concentration of 1.5% by mass, and set aside; another 20g of distilled water is used to swell and dissolve hyaluronic acid and sodium alginate to obtain the mass percent Concentrations are 1.5% and 0.5% solution respectively, for subsequent use; Then take 20g of distilled water, first make it into a concentration of 0.1% sodium hexametaphosphate solution, and then add TiO 2 Disperse it to get TiO 2 Suspension, ready for use; after dissolving olive oil and another or two kinds of oily substances at 70°C and mixing them uniformly, the oil phase is obtained. Then add oil-soluble components such as vitamin E succinate, stir evenly, and then add surfactant to obtain an oil-soluble solution; under the action of magnetic stirring at 40°C, slowly drop the remaining amount of distilled water into the oil-soluble s...

Embodiment 10～13

[0028] Embodiment 10~13: except distilled water, the content of other components is identical with embodiment 8, changes TiO 2 The contents are 1%, 3%, 4%, and 5%, and Examples 10-13 are respectively prepared according to the above-mentioned preparation method.

[0029] In each embodiment of 10-13, there is no mildew after being placed at room temperature for 6 months, and the appearance is uniform, delicate and shiny, but TiO 2 When the content is greater than 2%, it is not easy to smear and the higher the content, the stronger the graininess.

Abstract

TiO2-containing sunscreen nanoemulsion is prepared through steps as follows: olive oil and another one or two grease substances are compounded, an oil phase is obtained, and then a surfactant, an oil-soluble skin active component, perfume, a preservative and the like are added; after microemulsion is formed through drop-by-drop titration with distilled water, TiO2 dispersed by a sodium hexametaphosphate solution and water-soluble active components such as glycerin and the like are added, swelled hyaluronic acid, sodium alginate and a carbopol 980 solution are added, pH is regulated by triethanolamine, degassing and sterilization are performed, and a product is obtained. The TiO2-containing sunscreen nanoemulsion is prepared from components in percentage by mass as follows: 1%-5% of TiO2, 4%-6% of the oil phase, 5.5%-12% of the surfactant, 0.5%-1% of vitamin E succinate, 0-0.8% of menthol, 0.1% of the preservative, 0.01%-0.02% of the perfume, 3%-5% of glycerin, 0.2%-0.5% of deep-sea fish skin collagen, 0.02% of sodium hexametaphosphate, 0.5% of arbutin, 0.3% of carbopol 980, 0.1% of sodium alginate, 0.3% of hyaluronic acid, 0.01%-0.02% of triethanolamine and the balance of water.

Description

technical field [0001] The invention relates to a physical sunscreen nano-emulsion, in particular to a sunscreen nano-emulsion which is light, moist, fine and shiny, capable of realizing natural protection and multiple protections and a preparation method thereof. Background technique [0002] Regardless of season and age, in order to prevent tanning, sunburn, and sun aging caused by UVA and UVB in ultraviolet rays, skin isolation and sun protection need long-term attention. Commonly used sunscreens are divided into physical sunscreens and chemical sunscreens. Chemical sunscreens work through chemical reactions, and most of them can only provide selective protection, and cannot achieve full-spectrum protection in the UVA and UVB bands, and are easily absorbed by the human body to cause damage. Physical sunscreens are mainly TiO2 and ZnO, which act as sunscreens by reflecting and scattering light, and hardly cause harm to the human body because they are not absorbed by the h...
