Overview
Bitrex, chemically known as denatonium benzoate, is renowned as the most bitter-tasting compound in the world. It was discovered in 1958 and has since been widely adopted as a denaturant to prevent accidental ingestion of toxic substances. Its extreme bitterness makes it effective even in minute quantities, ensuring safety without altering the primary function of the product it is added to. In industrial and consumer applications, Bitrex serves as a critical additive in products like antifreeze, cleaning agents, and nail polish removers. Its non-toxic nature at recommended concentrations makes it a preferred choice for manufacturers aiming to comply with safety regulations while maintaining product efficacy.
Physical and Chemical Properties
Bitrex is a white crystalline powder with a molecular weight of 446.58 g/mol. It is soluble in water, ethanol, and propylene glycol, which facilitates its incorporation into various liquid formulations. The compound has a melting point range of 163-170°C, making it stable under typical storage and usage conditions. One of the most notable properties of Bitrex is its intensely bitter taste, detectable at concentrations as low as 10 parts per million (ppm). This characteristic ensures its effectiveness as a deterrent even when used in very small amounts. Despite its bitterness, Bitrex is chemically inert and does not react with most other substances, ensuring compatibility in diverse formulations.
Main Applications
Bitrex is primarily used as a denaturant to prevent accidental ingestion of toxic substances. It is commonly added to household products like cleaning agents, antifreeze, and nail polish removers to deter children and pets from consuming them. The compound is also used in industrial settings to ensure compliance with safety regulations. In the pharmaceutical industry, Bitrex is added to certain medications to discourage misuse. Additionally, it is used in alcohol-based products to denature ethanol, making it unfit for human consumption. Its versatility and safety profile make it a valuable additive across multiple sectors.
Safety and Storage
Bitrex is non-toxic at the concentrations typically used in consumer and industrial products. However, at high concentrations, it may cause mild irritation to the skin, eyes, or respiratory tract. Proper personal protective equipment (PPE), such as gloves and goggles, should be used when handling the pure compound. Storage of Bitrex requires a cool, dry environment away from direct sunlight to maintain its stability. The compound should be kept in tightly sealed containers to prevent moisture absorption and contamination. Proper labeling and handling procedures are essential to ensure safety in the workplace.
B2B Procurement Guide
When procuring Bitrex, buyers should verify the CAS number (3734-33-6) and purity specifications to ensure they are getting the correct product. It is advisable to request a certificate of analysis (CoA) from the supplier to confirm the quality and compliance with regulatory standards. Price ranges for Bitrex vary depending on purity and quantity, typically falling between $50 and $200 per kilogram. Buyers should also consider the supplier's reputation, delivery timelines, and compliance with local regulations. Bulk purchases may offer cost savings, but storage capacity and shelf life should be taken into account.
