The method of storing lipstick without mold can be carried out according to the following steps:
1. Store in a cool and dry place: Avoid placing lipstick in direct sunlight or high temperature and humidity environments. Sunlight and high temperatures can accelerate the oxidation reaction of oil and wax in lipstick, causing its texture to soften, pigments to decompose, and even leading to mold growth. Lipstick should be stored in a cool, dry, and well ventilated place, such as a drawer or storage box.
2. Cover immediately after use: After each use of lipstick, the lipstick cover should be immediately covered to reduce the contact time between lipstick and air, prevent moisture and bacteria from entering the interior of lipstick, and thus maintain the dryness and cleanliness of lipstick.
3. Refrigerated storage: For lipstick that has not been used for a long time, it can be stored in the refrigerator compartment. Refrigeration can lower the temperature of lipstick, slow down the oxidation rate of oil and wax, and thus extend the shelf life of lipstick. However, refrigerated lipstick should be avoided from frequent removal to prevent excessive temperature changes from affecting the texture of the lipstick. At the same time, lipstick should be placed in the refrigerated layer of the refrigerator instead of the frozen layer to prevent it from freezing.
By using the above methods, the shelf life of lipstick can be effectively extended to prevent it from mold and deterioration. At the same time, attention should also be paid to regularly checking the appearance and texture of lipstick. Once color changes, texture dryness, or cracking of lipstick are found, it should be promptly dealt with or replaced with a new lipstick.
