Cosmetic Bottle Packaging is not only Beautiful but also Safer
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, we must evaluate the safety of cosmetic bottle packaging.
Plastic cosmetic bottle packaging
The cosmetic bottle 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 lightweight, low price, excellent mechanical properties, easy molding, easy transportation, and good printability. It can be processed into bottles, caps, bags, tubes, boxes, and another packaging. Cosmetics have different forms such as solid, semi-solid, liquid and emulsion, solution, paste, block, etc. People can choose different plastics according to the shape and product shape of cosmetics.
At present, commonly used plastics are HDPE, PET, PP, PVC, PS, PMMA, and other materials. When plastic is selected as the primary packaging, stabilizers, antioxidants, plasticizers, and other additives will be added during processing to achieve performance requirements. Adhesives will also be used in the production of multi-layer composite materials. The existence of these substances Potential risk to the use of plastics. In addition, because 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. For general cosmetics, its 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 harm to human health, or chemical reactions between the substances in cosmetics and plastics to deteriorate the performance of plastics. Thereby deteriorating 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.
