Tert-Butylhydroquinone (TBHQ), identified by CAS number 1948-33-0, is a synthetic organic compound belonging to the phenol family. It is a derivative of hydroquinone with a tert-butyl group substitution, which significantly influences its chemical properties and applications. As a key ingredient for many industries, understanding its characteristics, uses, and safety profile is essential for manufacturers and formulators.

Chemically, TBHQ is known for its exceptional antioxidant capabilities. Its molecular formula is C10H14O2, and it typically presents as a white crystalline powder. This form allows for easy incorporation into various formulations. The primary advantage of TBHQ lies in its ability to inhibit autoxidation, a process that leads to the degradation of fats and oils, causing rancidity. This makes it an invaluable component for extending the shelf life of numerous products.

The most widely known application of TBHQ is in the food industry, where it serves as a food preservative. It is particularly effective in stabilizing unsaturated vegetable oils and many edible animal fats. Unlike some other antioxidants, TBHQ does not cause discoloration and is generally flavorless and odorless at recommended concentrations, ensuring that the sensory properties of the food product remain unaffected. It is often used in conjunction with other antioxidants like BHA (Butylated Hydroxyanisole) to achieve synergistic effects. For those seeking to buy TBHQ for food applications, ensuring compliance with food-grade standards is paramount.

Beyond its role in food preservation, TBHQ has significant industrial uses. In perfumery, it acts as a fixative, slowing down the evaporation of volatile fragrance compounds, thus enhancing the longevity of scents. It is also employed industrially as a stabilizer to prevent the autopolymerization of organic peroxides, crucial for the safe handling and storage of these reactive chemicals. Furthermore, TBHQ is utilized as an antioxidant in biodiesel, contributing to its stability and performance.

Regarding safety, regulatory bodies such as the European Food Safety Authority (EFSA) and the U.S. Food and Drug Administration (FDA) have evaluated TBHQ and deemed it safe for consumption within specified limits. These regulations ensure that the levels used in food products are well below those that might pose health risks. However, as with any chemical, proper handling procedures are essential during its manufacturing and industrial application. Manufacturers looking to procure TBHQ should source from reputable suppliers who can provide comprehensive safety data sheets (SDS) and ensure product quality.

In summary, Tert-Butylhydroquinone is a versatile and indispensable chemical. Its strong antioxidant properties make it vital for both food preservation and a range of industrial applications.
