BPS

BPS is similar to BPA in its estrogenic effects and is one of the replacements for BPA in thermal paper and baby bottles. BPS does not leach out of plastic as readily as BPA but when it does leach, it is more persistent in the body than BPA. BPA has an approximate half life of 24 hours, which means it takes about one day for your body to detoxify it. On the other hand, BPS has a half life of close to one year, so it requires two years for your body to remove it. The manufacturing industry has replaced the use of BPA with BPS and neglects to inform consumers. The easiest way to avoid bottles that contain either BPA or BPS is to stay away from plastics that have a #7 recycle symbol on the bottom of containers.
