BPA-free is the basic requirement of many water bottle wholesalers, why do we need BPA-free water bottles? auland will introduce you in detail.
Introduction of BPA
BPA (bisphenolA) is one of the most widely used industrial compounds in the world, chemical formula C15H16O2, white phenolic odor flaky crystals. Melting point 155~156 °c. Boiling point 250~252 °C (1.73kPa). Insoluble in water, soluble in ethanol, acetone and lye. It has low volatility and moderate toxicity, easy to biodegrade, and a half-life of 2.5~5 days. Mainly used in the production of polycarbonate, epoxy resin, polysulfone resin, polyphenylene ether resin, unsaturated polyester resin and other polymer materials. It can also be used in the production of plasticizers, flame retardants, antioxidants, heat stabilizers, rubber antioxidants, pesticides, coatings and other fine chemical products.
Application of BPA
In the manufacturing process of plastic products, the addition of BPA can make it colorless, transparent, durable, lightweight and impact resistant, especially to prevent acidic vegetables and fruits from the inside erosion of metal containers. So it is widely used in the packaging of canned food and beverages, feeding bottles, water bottles, sealants used in dental fillings, spectacle lenses and hundreds of other daily necessities manufacturing process.
Controversy and toxicity of BPA
The application of BPA is controversial, and the toxicity research data of BPA at home and abroad are mainly animal investigations and experimental results, and there are relatively few reports on population epidemiological investigations and human experimental studies on the toxic effects of BPA. Data show that BPA is a low-toxicity chemical. Animal tests have found that BPA has the effect of mimicking estrogen, and even very low doses can make animals produce precocious puberty, decreased sperm count, prostate growth and other effects. In addition, data show that BPA has certain embryotoxicity and teratogenicity, which can significantly increase the occurrence of ovarian cancer, prostate cancer, leukemia and other cancers in animals.
BPA requirements of different countries
Due to the characteristics of BPA such as low volatility and moderate toxicity, we generally do not use this BPA in the production of water cups. Although it is not fully proven that BPA causes poisoning in humans. However, some overseas countries have taken preventive measures to reduce the chances of their citizens (especially infants) consuming BPA. Customers in Canada have completely banned baby bottles and various water bottles containing BPA, while European countries has done the same thing like Canada. Other countries such as the United States, Japan and Australia also have some different requirements for BPA depending on the requirements of their end customers. Customers in India and the Middle East do not have as strict requirements for BPA as in Europe and the United States. It seems that they will be more strictly about BPA. And, it may be same as European country. Above all, there is almost no difference in BPA requirements for water bottle in different countries. All the country in the world refused to apply BPA into water bottle. They all insist BPA free.
