Mask cosmetics, scientific instruments protect the bright mood of young girls
Everyone has a love for beauty, and for many women, makeup can be said to be one of the most important things before going out every day. From a psychological point of view, for people who like makeup, makeup provides not only a modification on the makeup surface, but also a psychological hint, which can provide them with joy and confidence. However, for people who wear makeup, keeping the makeup clean and complete is also a technical task, especially when wearing masks for longer and longer, how to ensure the makeup after taking off the mask has become a technology. live. In this context, a series of special cosmetics were born, such as lipsticks that are not easy to fade, foundations that are resistant to scratches and so on. Once these cosmetics are launched, they have attracted many consumers to try, and they have gained a lot.“fan”, more and more cosmetic brands have also begun to try to enter this type of cosmetic market. Although, for users, the emergence of this kind of cosmetics undoubtedly provides a way to take into account wearing masks and makeup, but from the perspective of safety, the quality situation still determines whether such cosmetics can be reasonably marketed and sold in the market. The key to long-term circulation. So what quality issues should be paid attention to in mask cosmetics? In fact, the problems considered by traditional cosmetics are similar. Generally speaking, the main problems faced by traditional cosmetics include bacterial residues, excessive heavy metals, illegal use of hormones, excessive preservatives, and illegal use of additives (such as fluorescent whitening agents). To make matters worse, many of these safety hazards are packaged under the beautiful appearance. For example, if mercury is present in cosmetics, it has a good whitening effect on the surface. However, mercury is a highly toxic heavy metal and is easily absorbed by the skin. Long-term use will cause skin atrophy and cause chronic poisoning to damage body organs.

Of course, if the identification of these indicators cannot be completed with the naked eye, it is necessary to use scientific instruments. Generally speaking, there are many instruments used in cosmetics testing, such as atomic fluorescence spectrometer for mercury content detection, flame absorption photometer for lead content detection, gas chromatography for methanol content determination, and additives for additives. GC-MS for detection, etc. It is worth mentioning that there are clear suggestions or regulations in the relevant regulations regarding which instruments to use to detect which indicators.
