The bottle is made from 304 (18/8) medical grade stainless steel, the collar from polypropylene (no. 5 plastic), and the nipple from medical grade silicone.

All of our testing is either chemical testing or biological testing (on cells). We utilize third-party globally certified laboratories to conduct our testing.

How do I care for my Thinkbaby bottle?

Thinkbaby bottles are dishwasher safe (top rack recommended). When washing the baby bottles in the dishwasher, we recommend using a detergent that is free of chlorine. Most of the natural detergents on the market, from Eco Lever to Seventh Generation, should be free of toxic chemicals. If hand-washing, the American Pediatrics Association suggests using warm soapy water, but only if you live in an area with treated water systems.
