Graza Sizzle had the highest DEHT level in the test set (3,700 ppb)
Graza had significant microplastics >15μm, around 4x those generally reported in bottled water.
Costco (Kirkland) had the highest levels of DEHP, the most dangerous phthalate with Graza Drizzle being a close second
Glass bottled samples had lower total plasticizers, but not by much.
DEHP exposure is tied to hormone disruption, reproductive issues, and cardiovascular mortality
Graza had both the lowest and highest DEHT levels in our entire test set. For a brand built on quality and transparency, that kind of inconsistency raises real questions about control and exposure.
While the average phthalate levels were comparable to some glass-bottled oils, the wide variation across samples—including one that posted the highest DEHT result overall—points to potential instability in packaging or production.
Given the average phthalate content was comparable to glass bottled samples, we are not recommending full-on avoidance of Graza for those who enjoy the product.
We hope Graza uses this as an opportunity to improve its impressive supply chain, and become an industry leader in safe-plastic packaging.
Plasticizers—chemicals used to keep plastics flexible—don’t stay put. They migrate into fats like olive oil with ease. Two of the most common modern plasticizers are:
A 2025 global study from NYU Langone estimated that DEHP exposure contributed to 356,238 cardiovascular deaths worldwide in 2018. In the U.S., that included roughly 10% of all heart disease deaths among adults aged 55–64. Coverage in The Washington Post described DEHP as an “everywhere chemical” now linked to hundreds of thousands of heart disease deaths annually.
At 250 ppb, our highest DEHP result delivers 3–4 micrograms per tablespoon. That’s small, but still a notable piece of the total daily exposure range NYU’s study linked to increased cardiovascular risk.
