Truth be told, no plastic safe and should be avoided whenever
possible. However, at Your Guide To Green, we recognize that plastic
is an option some people are not willing to give-up and in that case,
we recommend they use a polycarbonate bottle. In all other case,
stainless steel is the safest and longest-lasting alternative.
Polycarbonate bottles are the least porous of any plastics: it is
because of this property along with their high heat-resistance
capacity that slows the rate of leaching compared to other plastics.
It is suspected that Bishphenol A (an endocrine disruptor) leaches at
a slow-rate from polycarbonate products. The same research also
states that children are a more at-risk population than adults.
All that being said, if you are trying to eliminate plastics from your
lifestyle then I would choose stainless steel. Our New Wave Enviro
stainless steel drinking canteens are all Aluminum free which often is
a concern with other stainless steel bottles.
