I received a water bottle for Christmas, but I cannot determine if it contains this material. Nothing on the bottle itself lists what it is made of.
Anyone know how to tell?

Isn't there a triangular recycle logo molded into the bottom?
Take a Q-Tip, dip it in acetone (Fingernail polish will work) and rub it on the bottle. If a thin film softens and glues cotton lint to the bottle, it could be Lexan (Polycarbonate). This plastic is used in cheap drugstore reading glasses, and since I often work with acetone, it is quite a nuisance to see tiny droplets making fisheyes on the lenses when I leave them on the bench and get clumsy.
There are other plastics like the butyrates that acetone will dissolve, but they are not used in food packaging.
Polycarbonate/urethane copolymers have been FDA aproved for use in some implants, and Lexan has been used in disposable labware such as Petri dishes for decades. I really would not worry about it, myself.
People who run injection molding machines are exposed to the fumes from the hot plastics. Since Lexan has been used for decades, if there were serious hazards, they would have shown up among these people, who would have had bisphenol A exposures many times that of the general population.
Does it have a recycle triangle? Start there.
Send it to me. I’ll use it for a couple years and then be able to tell you.

Only way for sure to know is to use the water bottle regularly and then try out for the Vienna Boys Choir. If you make it, then it probably had the hormone-mimicking chemicals.
