Dibutyl hydroxytoluene, commonly known as BHT, is a widely used synthetic antioxidant. It is well-known for its strong ability to inhibit oxidation and extend the service life of many products. It works by slowing down the degradation caused by oxygen, heat, and light, helping maintain stability and performance over time.

In petroleum products and fuels, BHT helps prevent the formation of harmful gums, sediments, and oxidative deterioration. It improves storage stability, reduces engine deposits, and supports consistent performance under different operating conditions.

In industrial oils, lubricants, and various chemical products, BHT protects against thermal and oxidative breakdown. It helps maintain product purity, extends service life, reduces maintenance needs, and improves overall reliability.
