Testing of beverage bottle cap liners reveals widespread use of toxic phthalates and PVC

In collaboration with our partners at Defend Our Health, the Healthy Stuff Lab has discovered that the gaskets lining caps or lids of glass-bottled beverages are frequently made of vinyl containing high levels of phthalates. "Vinyl" is short for polyvinyl chloride or PVC and "phthalates" is short for ortho-phthalate esters, a class of hazardous plasticizers added to vinyl plastic. Phthalates are not bound to the plastic, and we know from prior research that the chemicals migrate into food or liquid. 

Take Action! through our Toxic Free Food Campaign!

The good news is that several beverage companies have already taken quick action after we communicated our findings to them, and we continue to engage with companies. 

Phthalates have been phased out of many food-contact materials due to concerns about their links with health impacts including abnormal genital development and asthma. To determine their frequency in bottled beverages (non-alcoholic), we collected 273 caps from glass-bottled beverages and 10 caps from plastic-bottled beverages around the United States and Canada and tested the gaskets. 

Individual sample listings are below.** Results for gaskets from the 273 glass-bottled beverages are also aggregated as an Excel spreadsheet downloadable here.

**Due to our engagement, some companies have switched to different materials for their cap gaskets since their products were tested. Test results provide a snapshot of cap gaskets purchased in late 2019 and throughout 2020.
