Reasons why cosmetics are not full:
1. Considering the thermal expansion and contraction of the material body, it is normal to reserve a section of air.
2. The high air pressure in the bottle causes the cosmetics to leak out due to the altitude in different regions.
3. The bumps in the logistics and transportation, if it is full, it is easy to overflow.
4. There are chemical phenolic substances in perfume, which are very volatile, so half of the capacity of perfume is 75-80%;
If it is filled, it is easy for the contents to seep out, which will affect the appearance of the product at light level, or be polluted and the product will be scrapped. If the pressure is too high, the bottle will crack during transportation, and some special gas will explode.
This is the characteristics of the production process and raw materials. The product is a standardized production line, and the actual weight is the same as the one marked on the package, and one gram will not be less.
