    What Is tert-Butylhydroquinone/TBHQ CAS 1948-33-0?

    Tert butyl hydroquinone (also known as tert butyl hydroquinone, referred to as TBHQ) is a kind of phenol, which is composed of hydroquinone plus a tert butyl. Property white to light gray crystalline or crystalline powder It has a very slight special smell Suitable for crude oil and highly unsaturated grease. It is a highly effective antioxidant. In food, tert butyl hydroquinone is used as an antioxidant in vegetable oil and a variety of edible animal fats. In industrial production, it can be used as a stabilizer to inhibit the self polymerization of organic peroxides. It can also be added to biofuel as a corrosion inhibitor. In perfume, TBHQ can be used as a fixative to inhibit volatilization and improve stability. In addition, it is also used in paints, varnishes and resins.

    Application of tert-Butylhydroquinone/TBHQ CAS 1948-33-0

    1.Superior antioxidant performance, with stronger antioxidant capacity than BHT, BHA, PG (propyl gallate) and vitamin E; It can effectively inhibit the growth of Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Brevibacterium aerogenes and other bacteria, as well as Aspergillus niger, Aspergillus variegatus, Aspergillus flavus and other microorganisms.
    2.TBHQ is a safe and efficient edible oil antioxidant, which is suitable for vegetable oil, lard, etc. It is especially suitable for frying food because of its high melting point and boiling point. This product also has good anti-bacterial, mold and yeast effects, and can enhance the anti-corrosion and fresh-keeping effect of high oil-water food
    3.Antioxidant for rubber and plastic industry
    4.PVC additive (anti fisheye agent)
    5.For pharmaceutical intermediates, organic synthesis
    6.Stabilizer: prevent resin esters and other substances from being damaged by oxygen
