Cosmetic packaging is a container and material used to protect cosmetics, facilitate storage and transportation, and promote sales during the production, transportation and sales process. The primary packaging of cosmetics is a packaging container material that directly contacts cosmetics. Cosmetic packaging has metal, glass, ceramic, plastic, rubber and other materials, and plastic is currently the most widely used cosmetic packaging materials.
At present, commonly used plastics are HDPE, PET, PP, PVC, PS, PMMA and other materials. When choosing plastic as the primary packaging, stabilizers, antioxidants, plasticizers and other additives will be added during processing to meet the performance requirements, and adhesives will be used in the production of multi-layer composite materials. The existence of these substances will bring potential risks to the use of plastics. In addition, because the composition of cosmetics is complex and contains a large amount of alcohol, acid, protein and oil, it has a certain interaction with plastics, and for general cosmetics, its shelf life and use time can reach 1 to 2 years.
Prolonged contact between cosmetics and plastics may lead to the migration of monomers, additives, volatile substances, harmful substances, etc. in plastics, causing cosmetic pollution and harmful to human body, or the chemical reaction between substances in cosmetics and plastics makes the performance of plastics worse, thus reducing the stability and quality of cosmetics and deteriorating. Therefore, when plastic products are used as packaging materials for cosmetics, it is necessary to consider the safety and integrity of plastic packaging.

Soak the mascara brush in warm water, wait for the mascara on the mascara brush to soften, then gently wipe it with some makeup remover on a cotton pad until the mascara brush is clean, then rinse it with water, and dry it in a cool shade to dry.
The difference between using a lip brush and directly applying lipstick by hand is mainly reflected in the clarity, color uniformity, makeup effect, hygiene and naturalness.
