Embodiment 1～3

[0027] The method for preparing the novel high-efficiency sunscreen liquid foundation of the present invention has the following steps:

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

[0029] 2). Keep the stirring speed of the emulsifying pot at 30 revolutions per minute, suck the B component through vacuum, and homogenize at low speed for 5 minutes.

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

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

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

[0033] 6) Qualified inspectio...

Embodiment 3

[0055] Test sample: Example 3, Comparative Example 1

[0056] Evaluation method: Use a glass rod to take a sample of 0.02 g and place it on the center of the glass slide, then cover it with a cover glass, and lightly press to spread it about 1 cm 2 , Put it under a microscope, select a 100x lens, adjust the objective lens until the clearest display, and then take pictures for analysis and observation, the results are as follows Figure 1A with Figure 1B Shown. Example 3 (e.g. Figure 1B The particle size of the emulsified body shown) is smaller and the particle size distribution is relatively uniform), while the control example 1 (such as Figure 1A As shown, the particle size of the triacontanyl PVP) emulsion without the added film-forming agent is very large, and the dispersion is not uniform.

[0057] Experimental results: It can be seen from the microstructure of the product that Example 3 containing 2% triadecyl PVP has a finer emulsified structure, a more uniform particle siz...

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 specifically relates to a safe and efficient sunscreen liquid foundation containing innovative microcapsules and having a better sunscreen effect. Background technique [0002] The skin is the human body’s first barrier against bacteria, viruses, dust and other substances from the outside world. When the skin is exposed to excessive ultraviolet rays, it will damage the epidermal cells; activate tyrosinase, accelerate the synthesis of pigment, destroy the skin's moisturizing function, and make the skin It becomes dry, which damages the elastic fibers in the dermis and produces fine lines. Under strong irradiation, it can also cause skin inflammation and burns. In some cases, it will become pigmented skin cancer. [0003] Commercial sunscreen products are mainly divided into three types. The first is pure physical sunscreen products, which only contain physical sunscreen ingredients (such as nano-scale titan...
