2,6-Di-tert-butyl-p-cresol (DBPC)
2,6-Di-tert-butyl-p-cresol (DBPC, also known as BHT) — the classic hindered phenolic antioxidant. An ashless primary antioxidant protecting oils and fuels from oxidation.
The classic hindered phenolic antioxidant
DBPC — also known as BHT — is the classic hindered phenolic antioxidant, an ashless additive that protects oils and fuels by interrupting the oxidation chain reaction.
2,6-Di-tert-butyl-p-cresol (DBPC), also widely known as BHT, is the classic hindered phenolic antioxidant. As an ashless primary (radical-scavenging) antioxidant, it interrupts the oxidation chain reaction by donating hydrogen to peroxy radicals, protecting the oil from thickening, acid formation and deposit build-up. Being ashless, it adds no sulphated ash, making it valuable in modern low-SAPS oils, turbine oils, fuels and a wide range of industrial lubricants. It is often combined with aminic antioxidants for broad-temperature protection, and is part of the antioxidant & anticorrosion range.
