Cosmetic packaging is not only beautiful but also safer

In recent years, with economic development and people’s pursuit of beauty, cosmetics, as a product that can clean and beautify, have been strongly demanded by men, women and children, and the beauty industry in my country is booming. At the same time, my country’s cosmetics have greatly improved in terms of product quality and design, especially some domestic cosmetics are known as “new domestic products”, and their quality is no less than similar imported products, and they are warmly sought after by people. At the same time, in recent years, cosmetic quality problems such as excessive microorganisms and heavy metals and insufficient efficacy have emerged one after another, which has aroused strong concern.
Since cosmetics are applied to human surfaces such as skin, hair, nails, lips, etc. by rubbing, spraying or other similar methods, their safety is particularly important. Therefore, it is very necessary for us to evaluate the safety of cosmetics. Cosmetic packaging is a container and material used to protect cosmetics, facilitate storage and transportation, and promote sales in the process of production, transportation and sales. The primary packaging of cosmetics is the packaging container material that directly contacts cosmetics. Cosmetic packaging is made of metal, glass, ceramic, plastic, rubber and other materials, and plastic is currently the most widely used cosmetic packaging material. It has the characteristics of light weight, low price, excellent mechanical properties, easy molding, easy transportation, and good printability. It can be processed into bottles, caps, bags, tubes, boxes and other packaging. Cosmetics have different forms such as solid, semi-solid, liquid, emulsion, solution, paste, block, etc. People can choose different plastics according to the cosmetic shape and product shape.
At present, commonly used plastics are HDPE, PET, PP, PVC, PS, PMMA and other materials. When choosing to use plastic as the primary packaging, stabilizers, antioxidants, plasticizers and other additives will be added during processing to meet performance requirements, and adhesives are also used in the production of multi-layer composite materials. The existence of these substances Potential risks to the use of plastics. In addition, because the ingredients of cosmetics are very complex and contain a large amount of alcohol, acid, protein and oil, they have a certain interaction with plastics. For general cosmetics, the shelf life and use time can be as long as 1 to 2 years.
Long-term contact between cosmetics and plastics may lead to the migration of monomers, additives, volatiles, and harmful substances in the plastics, causing cosmetic pollution and harmful to human health, or chemical reactions between the substances in cosmetics and plastics to deteriorate the performance of plastics. It deteriorates the stability and quality of cosmetics. Therefore, when using plastic products as packaging materials for cosmetics, the safety of plastic packaging needs to be considered.
