1. Water solubility test method.
For lotion cosmetics, you can take a glass of water and pour the lotion into the water. If the emulsion floats and proves that the emulsion contains harmful substances, oil stone vinegar, do not use it; if the emulsion sinks to the bottom, it proves that it does not contain oil stone vinegar, you can use it with confidence.
2. Check whether the cosmetics contain emulsifiers (excessive use of emulsifiers will damage the skin tissue and cause skin cancer), and stir the emulsion in water.
If the water turns white, it proves that it contains too much emulsifier; some regular brand cosmetics will not contain oil stone vinegar and emulsifier.
3. Fire detection.
Pour the lotion into a spoon and burn it with fire. After it burns out, black powder will appear. The more powder, the more additives.
4. Detection of lead and mercury in cosmetics.
Coat silver products with lotion. If the silver products appear black, it proves that the cosmetics contain lead and mercury.
5. Product packaging inspection.
a. Check whether the product's outer packaging, production batch number, place of origin, country of origin, factory address, ingredient indication, and product label indicate the product name;
b. Internal container inspection: cleanliness and sealing degree;
c. Internal emulsion inspection: first look at the color, the emulsion type is generally lighter in color; second, look for bubbles, check whether there are bubbles in the emulsion; third, see if it is thin and thick; fourth, see if it is turbid, the genuine emulsion will not appear turbid; fifth, see if it is sticky For consistency, shake the cosmetics up and down to see the flow rate, fakes generally flow faster.
