How to save your lipstick?
During the daily shelf life and the expiration date of opening, lipstick storage also needs to pay attention to methods.
First of all, it is necessary to prevent high temperature and direct sunlight. Because the wax contained in the lipstick melts easily when exposed to high temperatures. In the national standard QB/T 1977 "Lipstick", the physical and chemical indicators of lipstick require that the heat resistance of lipstick is maintained at a temperature of 45°C for 24 hours, which means that the storage temperature of lipstick is better than 45°C. Daily storage is best stored in a cool place, preferably below 30 degrees.
If the lipstick melts and becomes soft, put it in the refrigerator for several hours and use it after the paste hardens.
Secondly, avoid damp, humid environment, bacteria accelerating multiplication, leading to deterioration.
In addition, close the lid immediately after use. When the paste is exposed to the air, the oil contained in it is easily oxidized, thereby accelerating the deterioration of the paste.
