BHA and BHT are antioxidants. Oxygen reacts preferentially with BHA or BHT rather than oxidizing fats or oils, thereby protecting them from spoilage. In addition to being oxidizable, BHA and BHT are fat-soluble. Both molecules are incompatible with ferric salts. In addition to preserving foods, BHA and BHT are also used to preserve fats and oils in cosmetics and pharmaceuticals.

Benefits of using BHA and BHT
– antioxidants
– used in cosmetics
– food preservatives

– can induce allergic reactions
– BHA is a human carcinogen, can cause cancer
– BHA as a Category 1 priority substance, based on evidence that it interferes with hormone function
– BHT can cause toxic in mice and rats
– BHT can act as a tumor promoter in certain situations
– Limited evidence suggests that high doses of BHT may mimic estrogen and prevent expression of male sex hormones
– both are risks but BHT is more safe for humans

All in all, I think that I would prefer BHT instead of BHA, simply because BHA is not that safe for humans. BHA can cause cancer and gayness (probably), while BHT is riskier for animals only. Though both can prove antioxidants and have good effects in cosmetics and in preserving food, I think that if they used BHT, it would be a lot safer and less of a risk than BHA
