Visible-light promoted degradation of the commercial antioxidants butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT): a kinetic study

Chemical intolerance to butylated-hydroxyanisole (BHA) and butylated-hydroxytoluene (BHT) and vascular response as an indicator and monitor of drug intolerance.

Different Modifying Response of Butylated Hydroxyanisole, Butylated Hydroxytoluene, and Other Antioxidants in A'jjV-Dibutylnitrosamine Esophagus and Forestomach Carcinogenesis of Rats1

The modifying effects of antioxidants were examined in a carcinogenesis system after \, V-ililnilvlniinisamiiic treatment. Male F344 rats were given 0.05% V, Vdilnilylnhrosarnmiin their drinking water for 4 wk and then treated with basal diet containing 2% butylated hydroxyanisole (BHA), 1% butylated hydroxytoluene (BHT) with 7 ppm vitamin K, 0.8% ethoxyquin, 5% sodium L-ascorbate, 57. sodium e...

The peroxidase-dependent activation of butylated hydroxyanisole and butylated hydroxytoluene (BHT) to reactive intermediates. Formation of BHT-quinone methide via a chemical-chemical interaction.

The food antioxidants butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) are shown to be metabolized to covalent binding intermediates and various other metabolites by prostaglandin H synthase and horseradish peroxidase. BHA was extensively metabolized by horseradish peroxidase (80% conversion of parent BHA into metabolites) resulting in the formation of three dimeric products. O...

Scientific Opinion on the re-evaluation of butylated hydroxyanisole – BHA

The Panel on Food Additives and Nutrient Sources added to Food (ANS) delivers a scientific opinion re-evaluating the safety of butylated hydroxyanisole (BHA) (E 320). BHA is a synthetic antioxidant authorised as a food additive in the EU that was previously evaluated by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) several times, the latest in 1989 and the EU Scientific Committee...

Endocrine disrupting effects of butylated hydroxyanisole (BHA - E320)

Butylated hydroxyanisole (BHA) is extensively used as antioxidant in foods, food packaging, cosmetics and pharmaceuticals. In the past years, it raised concerns regarding its possible endocrine disrupting effect. The existing in vitro studies indicate that BHA presents a weak estrogenic effect and also anti-androgenic properties while an in vivo study found it to have antiestrogenic properties....
