Embodiment 1～3

[0027] The preparation method of novel high-efficiency sunscreen liquid foundation of the present invention, its steps are as follows:

[0028] 1) Moisten magnesium aluminum silicate, xanthan gum, and tremella extract in component B with glycerin, then add it to the water phase pot, start stirring, add other components of component B in sequence, and heat up to 80°C. Incubate for 10 minutes until completely dissolved.

[0029] 2) The stirring speed of the emulsification pot is kept at 30 rpm, and the B component is sucked in by vacuum, and homogenized at a low speed for 5 minutes.

[0030] 3) Add the raw materials of component A into the oil phase pot one by one, then heat to 80°C, then suck component A into the emulsification pot through vacuum, start stirring, homogenize at low speed for 10 minutes, and cool down to 45°C.

[0031] 4) Add component C into the emulsification pot and stir evenly.

[0032] 5) Discharge when stirring down to 38°C.

[0033] 6), the inspection i...

Embodiment 3

[0055] Test sample: embodiment 3, comparative example 1

[0056] Evaluation method: Use a glass rod to take 0.02 grams of sample and dip it on the center of the glass slide, then cover it with a cover glass, and press lightly to disperse it by about 1 cm 2 , put it under a microscope for observation, choose a 100x lens, adjust the objective lens until it is displayed most clearly, then take pictures for analysis and observation, the results are as follows Figure 1A and Figure 1B shown. Embodiment 3 (as Figure 1B Shown) the particle size of the emulsified body is less, the particle size distribution is relatively uniform), while the comparative example 1 (such as Figure 1A As shown, the particle size of the emulsion without adding film-forming agent triaconyl PVP) is very large, and the dispersion is not very uniform.

[0057] Experimental results: It can be seen from the microstructure of the product that the emulsified structure of Example 3 containing 2% Triaconyl PVP ...

Abstract

The invention relates to a novel efficient sunscreen liquid foundation. An innovative microcapsule sunscreen liquid foundation is used for physically isolating chemical sunscreen components and the chemical sunscreen components only stay on the surface of a skin, so that the injuries on the skin are relatively small and the novel efficient sunscreen liquid foundation is safe and efficient; a better sunscreen effect can be realized by a relatively small dosage. According to the formula provided by the invention, a lot of plant anti-allergy and moisture-keeping components can be added so that the skin allergic rate is greatly reduced and an application range of the sunscreen product is widened; the novel efficient sunscreen liquid foundation is suitable for people with sensitive skins to use everyday, such as infants and pregnant women.

Description

technical field [0001] The invention belongs to the field of cosmetics, and in particular relates to a safe and efficient sunscreen liquid foundation containing innovative microcapsules and better sunscreen effect. Background technique [0002] The skin is the first barrier for the human body to block external bacteria, viruses, dust and other substances. When the skin is exposed to excessive ultraviolet rays, it will damage the epidermal cells; activate tyrosinase, accelerate the synthesis of pigments, destroy the moisturizing function of the skin, and make the skin It becomes dry, damages the elastic fibers in the dermis, causes fine lines, and causes skin inflammation and burns under strong sunlight. Even in some cases, it will become pigmented skin cancer and so on. [0003] Commercially available sunscreen products are mainly divided into three types. The first is purely physical sunscreen products, which only contain physical sunscreen ingredients (such as: nano-scale...
