BHA is in many foods, but you should know about its risks. The National Toxicology Program says BHA might cause cancer in people. Animal tests show BHA can make tumors in the stomach. High amounts in rats caused problems with growing and having babies. These problems include changes in hormones and organs not growing right. California says BHA could cause cancer, so products with BHA need warnings if used on lips.
Country | Regulation on BHA | Limitations |
|---|---|---|
Canada | High human health priority due to carcinogenicity. | Safe as a preservative in foods up to 0.02% of fat/oil; 0.005% in food packaging; 0.1% in defoamers. |
European Union | Prohibited as a fragrance ingredient in cosmetics. | Specific limits on BHT due to endocrine disruption; safe up to 0.001% in mouthwash, 0.1% in toothpaste. |
United Kingdom | Added BHT to the list of restricted substances in cosmetics in 2024. | Limits BHT in oral care products at 0.001%; 0.1% in toothpaste, 0.8% in other products. |
United States | Generally recognized as safe; known carcinogen in California. | Limits BHA to 0.02% of fat/oil; 0.005% in packaging; 0.1% in defoamers. |
BHA and BHT can build up in nature and hurt animals.
BHT Safety
BHT is in lots of foods, but it has risks too. BHT can hurt your liver and kidneys. If you eat a lot, it may cause tumors and lung problems. Some studies say BHT can change how blood clots. In fish, BHT made it hard for them to move and affected their nerves. Scientists are still learning how BHT affects the brain. The FDA checks how much BHT is safe in food and keeps getting new safety facts.
Category of Evidence | Description |
|---|---|
General Food Categories | BHT is used in various food categories such as cookies and soft drinks. |
Typical and Maximum Use Levels | The FDA is assessing typical and maximum levels of BHT in these food categories. |
Safety Data | The FDA is collecting safety data relevant to BHT’s use in food and as a food contact substance. |
