Children's crockery items are currently made from polyethylene, polypropylene, polyethersulfone (*) and melamine. Melamine is sometimes considered to pose a potential risk, if the residual monomer levels (and particularly the formol content) are not in line with the legislation or if the item is not used in an appropriate manner (e.g. if it is used in the microwave).
Childcare items such as dummies and teething rings may be made from Tritan® copolyester or polypropylene.
Receptacles for small household appliances may be made from Tritan® copolyester and polyphenylsulfone.
Plates and bowls for ready meals may be made of polypropylene, polystyrene, or a coordination complex based on polypropylene, ethylene copolymers and vinyl alcohol.
(*) The bisphenol S (BPS) can be used as starting monomer for the synthesis of polyethersulfone (PES), since BPS is structurally close to BPA, it is therefore a priori likely to present similar dangers.
