BHT

It neutralizes free oxygen radicals & prevents auto-oxidation of organic materials (prevents rancidity of fats & oils), extends shelf-life & stabilizes colorants of cosmetics. BHT’s typical usage of 0.01-0.1%, best used in combination with EDTA.

BHA

BHA is a petroleum-derived, synthetic antioxidant. It’s made by combining 4-methoxyphenol and isobutylene, and exists at room temperature as a white or slightly yellow, waxy solid with a faint, characteristic odour. Due to its antioxidant properties, BHA is used in cosmetic and personal care products, as well as in edible fats and oils, waxes, and vitamin A preparations
