Opis

Opis ogólny

Butylated hydroxyanisole (BHA), a lipophilic compound, is reported to exhibit antimicrobial activity against molds and Gram-positive bacteria. It also finds applications as a direct/indirect additive in adhesives, lubricants, food packaging materials, defoaming agents, as a preservative in cosmetic products, antioxidant in petroleum products including jet fuels, cutting oils, rubber latex gloves, paints, lacquers, adhesive hardeners, cleaning agents, thinners, plastics, etc.[1] It is also widely used as an antioxidant in food industry.††

This substance is listed on the positive list of the EU regulation 10/2011 for plastics intended to come into contact with food. Find all available reference materials for compounds listed in 10/2011 here

Zastosowanie

Butylated hydroxyanisole may be used as an analytical reference standard for the quantification of the analyte in the following:

• Food samples using square-wave voltammetry (SWV), further confirmed by high-performance liquid chromatography technique (HPLC)[2] and capillary electrophoresis (CE) coupled with end-column amperometric detection.[3]
• Cosmetics using fluorescence spectroscopy with second-order calibration, further confirmed by HPLC technique.[4]
