Butylated Hydroxytoluene (BHT) antioxidant

Butylated Hydroxytoluene (BHT) is a powerful antioxidant commonly employed in the fragrance industry to protect valuable ingredients from oxidation. As a nearly odorless, white to off-white crystalline powder with a subtle, musty phenolic aroma, BHT excels at preserving the delicate balance of scents and extending their shelf life. Its efficacy lies in its ability to neutralize free radicals, those unstable molecules responsible for degrading fragrance components and causing unpleasant changes in aroma.

By incorporating BHT into formulations, perfumers can significantly increase the stability of sensitive ingredients such as citrus oils, aliphatic aldehydes, and fixed oils. This not only prevents undesirable changes in fragrance profiles but also helps to maintain the vibrant and true-to-life nature of the scent over time. The use of BHT is particularly crucial for products containing oxygen-sensitive materials, as it safeguards against oxidation and the associated deterioration of fragrance.

While BHT is highly effective in extending the lifespan of fragrances, it is important to note that it does not completely halt the process of color change. However, it significantly slows down the development of discoloration, contributing to a more aesthetically pleasing and longer-lasting product. The typical usage rate for BHT in perfumery ranges from 0.1% for citrus oils, aliphatic aldehydes, fixed oils, and many other sensitive compounds. Its versatile nature allows for its incorporation into a wide array of finished products, ensuring optimal fragrance preservation and enhancing the overall consumer experience.
