1：Antioxidant – Inhibits lipid oxidation, prevents rancidity in oils and fats.
2：Heat stability – More stable than BHA/BHT at high processing temperatures.
3：Anti-microbial – Inhibits bacteria, molds, and aflatoxin formation.
4：Color stability – Prevents discoloration in plastics, rubbers, and coatings.
Key Applications of TBHQ
Used as antioxidant to preserve various oils, fats and food items by retarding their oxidative deteriation. It is used in formulating vanish, lacquar, resin and oil field additives. It is used as a fixative in perfumary to reduce the vaporation rate and improve stability. It is also used as a stabilizer to inhibit the auto-polymerization of organic peroxides.
