How to distinguish cosmetic oem Manufacturer Product quality. If the quality of cosmetics is not up to standard, it will not only not beautify the skin, but will also cause harm to the skin. Therefore, distinguishcosmetic oemFactory product quality, inspection of cosmetics oem The quality of the factory can usually be distinguished from the following four aspects.
A look at the color
Observe whether the color has changed. Because bacteria will produce pigments during the growth process, the original color of the cosmetics can turn yellow and black. If the color is different, be careful!
Smell the smell twice
Observe whether there are other odors or strange odors. Because bacterial growth is accompanied by fermentation, it can decompose the total organic matter of cosmetics, thereby producing sour or other odors. It is no longer the aroma that should be, but the disgusting sour and strange odors.
Three-point view
Observe whether it becomes dilute and water is out. Because bacteria contain active enzymes that hydrolyze proteins and esters, they can decompose proteins and esters in cosmetics, destroy the original emulsification state of cosmetics, and thus release the moisture contained in the emulsified structure. In addition, when cosmetics are placed in overheated and super-cooled places for a long time in a sterile state, water will become thinner (i.e., separation of oil and water layers).
Check the surface
Observe whether there are mold spots of various colors on the surface. This is because cosmetics are easily contaminated by mold and become moldy. Mold is most suitable for growing at a temperature of 24 ℃～28℃、In an environment with a relative temperature greater than 70%.
Anyone who has one of the above situations, whether it isoemThe cost is high or cheap,cosmetic oem The factory should not consider it to ensure that the cosmetics are qualified.
