Wholesale Carbomer 940 - tert-Butylhydroquinone TBHQ CAS 1948-33-0 with Purity 99% – Unilong Detail:
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.
