BHA is an antioxidant consisting of a mixture of two isomeric organic compounds, 2-tert-butyl-4-hydroxyanisole and 3-tert-butyl-4-hydroxyanisole. It is a waxy solid used as a food/feed additive with the E number E320. Used as an antioxidant and preservative in food, food packaging, animal feed, cosmetics, rubber, and petroleum products. BHA is also commonly used in medicines, such as Isotretinoin, Lovastatin, and Simvastatin.

We have devised a unique & novel process to produce BHA using MEHQ as the starting material. Here we have completely avoided the use of DMS (Di-Methyl Sulphate). We have a fully integrated BHA plant i.e. starting from Phenol to Anisole to MEHQ to BHA all at one location due to which can offer very competitive prices.

We have the following certifications – FAMI-QS, FSSC 22000, Halal, Kosher.
