What is the concern about BPA?
BPA is a chemical that in sufficient doses can mimic the action of the human hormone oestrogen. This can cause health problems to humans.
When PC is manufactured the BPA content is consumed by the raw material manufacturing process, however small quantities of BPA can migrate from PC plastic over time, or when exposed to excessive heat or conditions outside of normal use.
Many consumers are concerned about exposure to BPA, especially for infants, from this migrating, which has led to some countries already legislating about the levels of BPA in baby bottles.
