Cosmetic-grade plastic bottles are generally PC certified by the US FDA. Generally speaking, there is no problem, but it is still not recommended to choose PC-made water cups or baby bottles. The released toxic substance is bisphenol A (BPA). The following is an excerpt of whether the PC bottle releases bisphenol A.
The dispute over the release of bisphenol A from the PC bottle has revived. Recently, scientists at the University of Cincinnati in the United States studied the exposure of bisphenol A (BPA) in PC (polycarbonate) bottles. They found that the release of BPA has nothing to do with the old and new plastic containers, but is mainly affected by the temperature of the liquid in the container. The researchers pointed out that when the new and old polycarbonate cosmetic bottles were exposed to boiling water, the release rate of the environmental estrogen BPA was twice the release rate of the previous exposure to room temperature water. Researchers at the University of Cincinnati found that new and used polycarbonate cosmetic bottles release the same amount and rate of BPA in cold and warm water, except that the BPA release level will be dramatic when the cosmetic bottle is placed in boiling water. The change. For the same cosmetic bottle, before being exposed to boiling water, the rate of BPA released from the bottle is ~.ng/h, and after being placed in boiling water, the release rate increases to ~ng/h, which is ~ times faster.
In order to test the safety of the repeated use of cosmetic grade plastic bottles throughout the life cycle, researchers at the University of Athens also conducted repeated tests on the release rate of BPA in polycarbonate bottles, and proved that the release rate of BPA in boiling water is indeed higher Low temperature water, but after ~ cycles of repeated use, the BPA migration speed drops rapidly, even if boiling water is used in each cycle. This indicates that the increase in the release rate of BPA in boiling water is only a transient phenomenon, and the rate will drop quickly when it continues to be used.
Mainly engaged in plastic plastic cans and paper packaging products. After nearly five years of construction and development, we already have process equipment for the entire process of plastic plastic cans and paper packaging, with an annual output of more than 80 million plastic products. Comprehensive production capacity.
