How to store nail polish?

Many female friends like to buy some nail polish for themselves, but the amount of nail polish used each time is very small, and it usually takes a long time to apply it once. In addition, nail polish is very volatile. Improper storage for a long time will cause it to evaporate in large quantities, making the texture of the nail polish dry and thick, and sometimes the color will also appear abnormal, affecting its use.

Nail polish is not a daily maintenance product. It may stay on the dressing table for more than half a year. How to avoid using spoiled nail polish or save it from the fate of going to the trash can?

1. When nail polish becomes sticky, dries, or has color separation, you should suspect that it has gone bad.

2. The general shelf life of nail polish is about two years, and unopened nail polish can be stored for three years.

3. The bottle mouth must be tightly closed, otherwise the solvent inside will easily evaporate. Once the ingredients evaporate, the nail polish will become thick and dense.

4. If the nail polish becomes thick, there are commercially available thinners that can be used to save it. But nail polish should only be diluted two or three times.

5. Acetone or nail polish remover are not suitable for diluting nail polish.

6. If nail polish has not been used for a period of time, the pigment will settle and it needs to be shaken. The metal ball inside the bottle will disperse the ingredients at the same time.

The texture of nail polish is also an effective way to determine whether it is expired. Compared with new nail polish, nail polish with an earlier production date will appear thick and easy to clump, and it is not easy to apply evenly when using it. Because when nail polish is left on for a long time, the various ingredients in the nail polish begin to clump, and it is no longer easy to mix them together.

Since expired nail polish is harmful to health, it must not be used. Do not continue to use it just because you think it is a pity.

Nail polish contains some substances that are harmful to human health. After it has expired, it is best not to pour it directly into the sewer or water source to avoid causing certain pollution to the surrounding environment. At this time, it is best to tighten the nail polish bottle cap and throw it into the corresponding classified trash can.
