BHT- ▸ Polymer stabilizer: Antioxidant for plastics and synthetic rubber.
- ▸ Fuel & oil antioxidant: Oxidation inhibitor in gasoline, oils, and waxes.
- ▸ Anti-skinning agent: Prevents skin formation in paints and inks.
- ▸ Food/feed grade: Antioxidant in foods and animal feed (purified grades).
A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →Butylated Hydroxytoluene (CAS 128-37-0), or BHT, is a hindered-phenol antioxidant. It inhibits oxidation in fuels, lubricating and process oils, waxes, synthetic rubbers, and plastics, functions as an anti-skinning agent in paints and inks, and in purified grades serves as a food and animal-feed antioxidant.

Frequently Asked Questions
What is 2,6-di-tert-butyl-4-methylphenol (BHT) used for?
BHT (CAS 128-37-0, C15H24O) is a hindered-phenol antioxidant. It inhibits oxidation in fuels, lubricating and process oils, waxes, synthetic rubbers, and plastics, acts as an anti-skinning agent in paints and inks, and in purified grades serves as a food and animal-feed antioxidant. RawSource supplies it in bulk to industrial and food formulators.
Is 2,6-di-tert-butyl-4-methylphenol the same as BHT?
Yes. 2,6-Di-tert-butyl-4-methylphenol is the systematic name for BHT (butylated hydroxytoluene), CAS 128-37-0. The hindered phenol structure is what gives it antioxidant function.
How does BHT differ from 2,6-di-tert-butylphenol or methylenebis hindered phenols?
BHT carries a methyl group at the 4-position of a 2,6-di-tert-butylphenol ring, while 2,6-di-tert-butylphenol lacks that para-methyl, and methylenebis(4-methyl-6-tert-butylphenol) is a higher-molecular-weight bisphenol antioxidant. These are distinct CAS items with different volatility and performance; confirm identity by CAS on the CoA.
What grades of BHT are available and what HS code applies?
BHT is offered in industrial/polymer-stabilizer grades and in purified food/feed grades; specify your application so the right grade and CoA are matched. It classifies under HS 2907.19 (monophenols, other). Confirm grade and tariff line when ordering.
How is bulk BHT packaged and quoted?
RawSource supplies BHT in bulk (bags, drums, and supersacks depending on form) to manufacturers. Pricing is volume- and grade-dependent, so request a bulk quote with your target quantity and grade; CoA and SDS accompany each shipment.
What is the REACH and TSCA regulatory status of Butylated Hydroxytoluene (BHT)?
Butylated Hydroxytoluene (BHT) (CAS 128-37-0) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 204-881-4).
