The purpose of using the discrimination test in real time is to see if the essence is well absorbed. The detailed operation method is to observe the soaking of the essence on the paper towel or cotton pad, the easier it is to soak down. This means that these molecules are small, penetrable, and easily absorbed by the skin. If it only spreads on the surface, it shows that the permeability is poor and the absorption is not good. Through the small molecule permeability test of this cotton pad, the advantages and disadvantages of the essence can be seen. The purpose of the cosmetic pH discrimination test is to see if the lotion is mild enough to have no effect on the skin. Before the experiment, prepare the pH test paper and put some lotion on the test paper. If the pH value is less than, the red color of the test paper is acidic; if the pH value is greater than the color is blue, it is alkaline. If the measurement is close to neutral pH or close to skin pH. This means that your toner is very mild and will not affect the skin. But if you want your lotion to have astringent or exfoliating properties, pH-is the best. The purpose of the emulsion discrimination test is to see if the lotion or cream is simply absorbed. The principle of the experiment is to test the type of emulsion with water. In short, it can be divided into oil in water and water in oil. The oil in the water is simply absorbed and fresh, while the water in the oil is not easily absorbed. The detailed operation method is to put the emulsion or cream into the water the size of mung bean. Generally, the oil in the water will float on the water surface and will gradually melt into milky white with a little stirring. On the contrary, most oil-in-water emulsions or creams sink under water and are not easily dissolved in water. This way you can easily identify the lotion.
