Tert-Butylhydroquinone (TBHQ) Identification: Chemical Name: tert-Butylhydroquinone Synonyms: tertiary butylhydroquinone;TBHQ; Antioxidant TBHQ CAS No.: 1948-33-0 Molecular Formula: C10H14O2 E-Code: E319 Properties: TBHQ as one of the best antioxidants , had been used in oil and Greasy food industry around several countries and areas, and instead of traditional antioxidants. The relative effectiveness of synthetic antioxidants when used separately are as follows: In vegetable oil :TBHQ >PG >BHT>BHA In animal fats: TBHQ >PG >BHA >BHT>V Specifications: Appearance White crystalline powder Identification Meets the requirements UV Absorbance Meets the requirements Assay ≥99.0% Melting Point 126.5 ~ 128.0 Hydroquinone ≤0.1% 2,5-di-tert-butylhydroquinone ≤0.2% t-Butyl-p-benzoquinone ≤0.2% Toluene ≤0.0025% Heavy Metals (as Pb) ≤10mg/kg Lead ≤2mg/kg Arsenic (as As) ≤3mg/kg Standard FCCⅤ Application: TBHQ is a highly effective antioxidant. In foods, it is used as a preservative for unsaturated vegetable oils and many edible animal fats. It does not cause discoloration even in the presence of iron, and does not change flavor or odor of the material to which it is added. It can be combined with other preservatives such as butylated hydroxyanisole (BHA). It is added to a wide range of foods, with the highest limit (1 gram/kg) permitted for frozen fish and fish products. Its primary advantage is enhancing storage life. It is used industrially as a stabilizer to inhibit autopolymerization of organic peroxides. It is also used as a corrosion inhibitor in biodiesel. In perfumery, it is used as a fixative to lower the evaporation rate and improve stability. It is also added to varnishes, lacquers, resins, and oil field additives. Packing& Storage: 25kgs/drum, inner by double plastic bag. Stored in a cool&dry well-closed container, keep away from moisture and strong light/heat.
