Cosmetic packaging should not only be beautiful but also safe
In recent years, with economic development and people's pursuit of beauty, cosmetics, as a product that can clean and beautify products, are 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 styling design, especially some domestic cosmetics are known as "new domestic products", and the quality is no less than similar imported products, which are enthusiastically 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 people's strong concern.
Since cosmetics are applied to human surfaces such as skin, hair, nails, and lips 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 special container and material for protecting cosmetics, facilitating storage and transportation, and promoting 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, ceramics, 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, convenient transportation and good printing performance. It can be processed into bottles, caps, bags, hoses, 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 form and product shape.
At present, the commonly used plastics are HDPE/PET/PP/PVC/PS/PMMA and other materials. When choosing plastic as primary packaging, additives such as stabilizers, antioxidants, and plasticizers are added during processing to meet performance requirements, and adhesives are also used when producing multi-layer composite materials. The presence of these substances Potential risks to the use of plastics. In addition, since the composition of cosmetics is very 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 up to 1-2 years.
Prolonged contact between cosmetics and plastics may lead to the migration of monomers, additives, volatile substances, harmful substances, etc. in the plastics, causing cosmetics to be polluted and harmful to the human body, or chemical reactions between cosmetics and plastics to deteriorate the performance of the plastics, thus Decrease the stability and quality of cosmetics and cause deterioration. Therefore, when using plastic products as packaging materials for cosmetics, the safety of plastic packaging needs to be considered.
