I'm have been looking into the use of plastics and kids toys because San Francisco recetnly passed a law regarding it. On June 16, Mayor Gavin Newsom signed into law (effective December 1, 2006) the Stop Toxic Toys bill, which would ban two toxic chemicals—phthalates and bisphenol-A—from children’s toys and feeding products. Apparently much of Europe has already banned the use of these plastics, but the US has not.
I thought it sounded like a good idea, but I had no idea which plastics contained the dangerous chemicals. How do I know if our sippy cups are okay?
Environment California has some great information on their website, including a list of what phthalates and bisphenol-A can do to you.
I also learned that it is a good idea to avoid plastics with the numbers:
#3 PVC - phthalates (hormone disruptor)
#7 polycarbonate - bisphenol-A (hormone disruptor)
#6 polystyrene - styrene - possible human carcinogen
The better plastics are:
The containers need to be discarded if they get worn down, degraded, overused etc.
It seems to be a good idea to avoid heating plastics, and possibly even freezing in them as the temperature changes can cause leeching.
Many of our sippy cups and items didn't have numbers on them. I ended up tossing anything that was worn or that I wasn't sure about (especially plastic bath toys that get chewed on. most rubber duckies are pvc!)
I was very glad to learn that our favorite sippy cups are safe. My kids love tomee tippy cups.I called the company to see about the plastic safety and they assured me that since they are made in England they are held to a higher standard and none of those toxins are permitted in the plastics.
Environment california also has a shopping guide pdf document to keep your kids toxic-free.
We did finally get rid of the tomee tippy cups as well. I was concerned they may contain Bisphenol A since they are made form plastic #7. When I called the company I had been specifically asking about phalates only. We now use Sigg bottles when we need a spill-proof option.
