Here’s an interesting article about it.
According to the article:
The ban, which took effect in February, prohibits making or selling duckies and other children’s products that contain chemicals called phthalates, which are used to make plastic soft. Congress passed the ban in 2008 after concluding that the chemicals posed a risk to children who chew on their toys.
The action came despite advice not to enact the ban from scientists at the Consumer Product Safety Commission, which regulates toys.
