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...
