Thinkbaby
Built around avoiding specific problem plasticizers — BPA, BPS, phthalates, PVC — rather than avoiding plastic itself, and that distinction matters here. The steel-bodied straw bottle we list pairs a 304 stainless body and silicone straw with a polypropylene collar and valve, meaning the water passes through plastic on its way to the child, which is why it rates only minimal-contact. So the brand's "safe from the bad additives" framing coexists with polypropylene sitting right in the drinking path. It's a reduced-additive posture, not a plastic-out one.
How clear are their specs?
They name the good stuff — 304 stainless body, medical-grade silicone straws — and list what they exclude, but the polypropylene collar and valve in the water path get less emphasis than the "free of BPA/BPS/phthalates/PVC" messaging.
Lead testing disclosure
Thinkbaby/Thinksun's "Testing + Chemical Policy" page claims products are "tested down to the ND (non detect levels)" and lists excluded chemical classes, but names no testing lab, cites no actual lead/cadmium ppm or detection-limit numbers, and provides no lab report - a general policy statement, not disclosure. The page also states the company does not allow outside distributors or foreign governments to conduct their own testing. Separately, independent third-party lab testing (Lead Safe Mama, 2025) of Thinkbaby sunscreens (a different product line) found significant lead and cadmium contamination, which the brand has not addressed on its site.
