There has been a lot of hue and cry about the fact that BPA and epoxy resin are present in children's products like baby bottles and plastic toys. BPA happens to be the main component of polycarbonate, from which certain plastic toys like rattles and teethers are made of.
Most of the BPA enters our body via our diet. It's also a concern for babies since babies tend to mouth their toys and this could possibly be a route by which BPA enters our body. BPA also happens to be unstable, especially when exposed to heat, acidic or basic conditions. This means that more BPA could leach out of plastics when it comes in contact with bleach, harsh detergents or heat, a common encounterance in dish washers and microwaves.
BPA is a dangerous chemical which can cause a lot of harm to our health in the long term.
