Antioxidant in Food Products
BHA is widely employed as an antioxidant in fatty foods, such as vegetable oils, animal fats, and baked goods, to prevent rancidity and maintain product freshness. It helps to inhibit the oxidation processes that lead to undesirable flavour and odour changes.
Preservative in Cosmetics
In cosmetic formulations, BHA acts as an antioxidant to protect ingredients, particularly those prone to oxidation like fragrances and fats, from degradation. This helps to ensure the stability and efficacy of cosmetic products over time.
Stabilizer in Pharmaceuticals
BHA serves as a stabiliser in certain pharmaceutical preparations, particularly those containing active ingredients sensitive to oxidative breakdown. Its inclusion helps to maintain the potency and integrity of medications.
Chemical Synthesis Intermediate
As a phenolic compound, BHA can be utilised as a building block in chemical synthesis for the creation of more complex organic molecules. Its structure offers reactive sites for further chemical modification.
