Cobalt - 8-oz bottle (Angstrom)
The Mother Earth Minerals 8oz bottles are plastic. Do plastic bottles leech chemicals into the product? While this is certainly true with certain kinds of plastic bottles, for example, cheap milk bottles, we specifically chose Polyethylene Terephthalate (PET #1) for our Minerals. This plastic is a strong, lightweight plastic resin and form of polyester that closely resembles glass in clarity and functionality and takes colorants well. PET is commonly used in food packaging due to its strong barrier properties against water vapor, dilute acids, gases, oils, and alcohols. PET is also shatter-resistant, slightly flexible and easy to recycle, and does NOT leach petrochemicals into the product stored within it. The truth is that certain PET plastics are actually found to be more stable, and more leach-proof via independent lab testing than glass. Our cobalt blue, 8 oz. bottles are specially designed, manufactured, and tested by Alpha Packaging company - and we chosen this for our 8 oz. refill bottles because of the test results - and for no other reason. Leaching of petrochemicals is non-existent in MEM PET cobalt bottles.
