What Is BHT (Butylated Hydroxytoluene)?
BHT (butylated hydroxytoluene) is a synthetic antioxidant used to prevent fats and oils from breaking down. It commonly appears in foods, medications, cosmetics, and pet products to extend shelf life.
BHT works by slowing oxidation, which helps products stay stable during storage. Because it is effective in very small amounts, it is often used in processed items that contain fats or oils.
You may see BHT listed on labels under several names, including:
- BHT
- Butylated hydroxytoluene
- Butylated hydroxy toluene
- Butyl hydroxy toluene
Where BHT Is Commonly Found
- Processed foods and snacks
- Medication coatings and inactive ingredients
- Pet food and treats
- Cosmetics and personal care products
Safety & Allergy Considerations
Some people look up BHT after experiencing reactions or concerns related to additives. While regulatory agencies allow its use within limits, individuals with sensitivities may wish to verify whether BHT appears in a specific product.
Ingredient Verification Tip
Ingredient lists vary by manufacturer and formulation. If you are checking a medication, food, or pet product, always confirm the exact label text rather than relying on generic ingredient summaries.
Enter the name of any prescription or over-the-counter medication to reveal its active and inactive ingredients, dosage forms, and potential allergen alerts.
