(Redirected from BHA)

'Butylated hydroxyanisole' (BHA) is a mixture of two isomeric organic compounds, 2-''tert''-butyl-4-hydroxyanisole and 3-''tert''-butyl-4-hydroxyanisole. It is prepared from 4-methoxyphenol and isobutylene. It is a waxy solid that exhibits antioxidant properties.
Like butylated hydroxytoluene (BHT), the conjugated aromatic ring of 'BHA' is able to stabilize free radicals, sequestering them. By acting as free radical scavengers, further free radical reactions are prevented.
The National Institutes of Health considers BHA ''reasonably anticipated to be a human carcinogen''.^[1]
