General description

Butylated hydroxyanisole is mainly used as a synthetic antioxidant in food and cosmetics. It is being extensively studied for potential toxicity.

Application

  • Antioxidant peptides from silk protein: Research explores the purification of novel antioxidant peptides derived from Bombyx mori pupae, identifying potential antioxidant applications for butylated hydroxyanisole in the food and cosmetic industries (Chukiatsiri et al., 2024).
  • Industrial lubricant additive: The performance of olive oil-based blended esters with butylated hydroxyanisole is evaluated, showcasing its efficacy as an industrial lubricant additive and its optimization using response surface methodology (Thangaraj et al., 2024).
  • Environmental degradation studies: Investigates the degradation of butylated hydroxyanisole using advanced oxidation processes, providing insights into environmental safety and the compound′s stability in pharmaceutical and industrial applications (Shi et al., 2024).
