Why does the safety of packaging materials for cosmetics have a huge impact on the safety of cosmetics? Because once the packaging material itself contains excessive amounts of toxic and harmful substances, it may be slowly released into the cosmetics directly in contact with it, causing the quality of the cosmetics to change in a bad direction, which in turn causes great harm to the human body. This hazard is similar to the effect of food on the human body - it will be absorbed by the body, causing serious consequences. Therefore, the development of detection of harmful substances in cosmetic packaging materials will be inevitable, and the standards related to the materials of national food packaging are a good reference for studying the migration of materials in packaging. So where do the toxic and harmful substances that affect the safety of cosmetics come from?
1.additives in the package. The most widely used and most frequently used today is plastic. Compared with other ceramics, glass and other materials, its advantages are unquestionable - light weight, high strength, good tolerance and low cost. However, its flaws can not be ignored - additives of various functions and its own degradation. There are many types of additives, the most common ones are 1. Filler (changes the hardness, wear resistance and dimensional stability of plastics, commonly used in gypsum, metal powder, paper wood, etc.)
2. plasticizer (strengthen the softness, elasticity and fluidity of plastics, commonly used phthalic acid, epoxy compounds, etc.)
3. stabilizer (to prevent aging, degradation, commonly used aromatic amines, etc.)
4.coloring agents Many of them are toxic and hazardous substances, such as phthalic acid and amine compounds. These additives, together with the monomer degraded by the plastic itself, will migrate into the cosmetics after being in full contact with the cosmetics, thereby burying hidden dangers to human health.
In the food packaging regulations "Sanitary Standards for the Use of Additives in Food Containers and Packaging Materials" (ie GB9685-2008), the 959 additives allowed to be used are listed and their use, maximum residue and specific migration amount are made. There are clear rules. If we can refer to similar standards and establish a limited edition of the materials used in cosmetic packaging materials, we can greatly reduce the chemical pollution of cosmetics from the source, and reduce the harm to human health to a greater extent.
5.is the heavy metal content in the package When the human body excessive intake of heavy metal elements, it will cause great damage to health. For example, excessive lead can interfere with the synthesis of heme, affecting intellectual development and the reproductive system; long-term exposure to excessive chromium in the skin is likely to cause contact dermatitis and eczema; mercury can affect the central nervous system. In China's current food packaging material standards, GB19778-2005 defines the amount of lead, cadmium, arsenic and antimony dissolved in food glass (for example, containers smaller than 600mL, the lead, cadmium, arsenic and antimony dissolved in 1.5 respectively. Mg/L, 0.5mg/L, 0.2mg/L, 1.2mg/L), while GB12651-2003 limits the amount of lead and cadmium dissolved in ceramics (the amount of lead and cadmium in common cups is 0.5mg/ L, 0.25 mg / L).
However, in addition to ceramics and glass products, Sprayer Bottles, paint and even paper products often contain certain heavy metals – such as tinplate cans, papers with paint or adhesive added. If the packaging material comes into contact with cosmetics, especially weakly acidic products, it will slowly enter the cosmetics and then be absorbed by the skin; more than this, when the packaging is discarded, the heavy metals contained in it will slowly penetrate into the soil or In the water, it brings extremely deadly damage to our environment. If we can establish a standard for the content of heavy metals in cosmetic packaging materials, it will be a great improvement for the safety of cosmetics, and it will contribute to our society and our environment.
Therefore, the research and testing of the potential risks of chemical substances contained in cosmetic packaging materials can not only add corresponding knowledge reserves to the quality inspection system of cosmetics, but also provide a powerful barrier to people's health and safety and environmental protection.
