Butylated Hydroxyanisole (BHA), is a chemical used as a preservative in several industries including food, cosmetics, and pharmaceuticals. They are also used for producing other esters and acids. This blog features the making procedure, uses, and a list of companies that are trusted and reliable suppliers of BHA and other chemicals.
What is Butylated Hydroxyanisole?
Butylated Hydroxyanisole or BHA is a synthetic antioxidant that serves as a food additive. It is commonly used to prevent the oxidative rancidity of fats and oils. This additive aids in increasing the shelf life of different processed foods. It is also used in cosmetics, pharmaceuticals, and industrial applications because it prevents the degradation of products exposed to oxygen. The mechanism of BHA involves preventing the formation of free radicals, which are very reactive molecules that can cause and promote oxidation reactions.
Although very common, BHA has been an object of controversy and research about its safety. As a result, regulatory bodies including FDA and EFSA are constantly evaluating the safety of BHA to determine acceptable daily intake levels that minimize the likelihood of adverse effects. Although BHA is still authorized to be used in a wide range of products, the continuous scientific review emphasizes the need for balancing between its benefits as an antioxidant and possible health implications.
How is Butylated Hydroxyanisole Made: Manufacturing Process
Butylated Hydroxyanisole (BHA) is synthesized through several chemical steps in the manufacturing process of this synthetic antioxidant. The main raw materials are 4-methoxyphenol (hydroxyanisole) and isobutylene.
The manufacturing process can be summarized as follows:
- Alkylation: Isobutylene reacts with 4-methoxyphenol in the presence of a catalyst such as sulfuric acid. This alkylation reaction produces tert-butyl-4-methoxyphenol, an intermediary compound.
- Hydrogenation: The intermediate compound is hydrogenated, a process whereby hydrogen is added to the molecule converting tert-butyl-4-methoxyphenol into Butylated Hydroxyanisole (BHA). This step is essential for the stabilization of antioxidants.
- Purification: The BHA product is further purified to eliminate impurities or byproducts. For this reason, techniques such as distillation and crystallization are often used.
- Formulation: Purified BHA is frequently combined with carriers or other ingredients to produce a stable and usable product. This may depend on the intended use of the formulation be it in food, cosmetics, pharmaceuticals, or industrial processes.
Quality control measures are strictly observed throughout the manufacturing process to guarantee the purity and safety of the final BHA product. Agencies regulate it with guidelines to control its use in different industries and applications.
Major Uses of Butylated Hydroxyanisole
However, BHA has a widespread application in different industries because of its antioxidant capability, which helps prevent the oxidation of fats and oils. Here are its major applications:
- Food Industry: The use of BHA is widespread as a food additive to increase the shelf life of processed foods with fats and oils. It prevents rancidity and preserves the quality of such products as snacks, baked goods, or cereals.
- Cosmetics and Personal Care Products: In cosmetics, skincare products, and toiletries BHA is used to improve the stability of oils and fats which prevents their oxidation. It is commonly used in lipstick, moisturizers, and sunscreen formulations.
- Pharmaceuticals: BHA is used in the pharmaceutical industry to maintain the stability of some medicines and prevent the oxidation of ingredients that are sensitive to air. It helps in preserving the efficiency and validity of pharmaceutical products.
- Industrial Applications: In the industry, BHA is used to stop the degradation of materials that are under oxygen and other environmental conditions.
- Animal Feed: In some cases, BHA is added to animal feed to prevent fat oxidation in the feed which guarantees the quality and safety of nutrients over time.
Though BHA is generally considered safe in certain concentrations, further research and regulatory evaluations still evaluate its uses and health concerns.
Differences Between Butylated Hydroxyanisole & Butylated Hydroxytoluene
Synthetic antioxidants, BHA, and BHT are used widely in the food, cosmetic, and pharmaceutical industries. The main difference is in their molecular structures. BHA is obtained from 4-methoxyphenol, while BHT is obtained from 4-methylphenol. They are both inhibitors of the oxidation of fats and oils, prolonging product shelf life. BHA is more soluble in fats, so it should be used for lipids while BHT is a better choice as an antioxidant for oil-based products. Although they are alike, their chemical structures may impact the uses and efficacy of different formulations.
Butylated Hydroxyanisole vs. Beta Hydroxy Acid
Butylated Hydroxyanisole (BHA) and Beta Hydroxy Acid are separate compounds that serve various purposes. Beta Hydroxy Acid like Butylated Hydroxyanisole is a synthetic antioxidant used in the food, cosmetic, and pharmaceutical industries to inhibit the oxidation of fats and oil prolonging product shelf life. It functions by preventing free radical formation.
Alternatively, Beta Hydroxy Acid is a collective term for chemical compounds with a hydroxyl group in the beta position, such as salicylic acid found in skincare products. In the world of skincare, BHA is an exfoliating agent that penetrates oil to unclog pores and works well in acne. Though they have the same “BHA” acronym, these two chemicals are used for completely different intentions — one as a preservative antioxidant and the other as an exfoliating chemical with skincare benefits.
