Triethanolamine CAS NO (102-71-6) At Good Price

Comprehensive Overview of Triethanolamine (102-71-6):

Introduction: Triethanolamine (TEA) is a versatile organic compound belonging to the class of ethanolamines. It is characterized by its clear, colorless to pale yellow appearance and is widely used in various industrial, commercial, and consumer applications due to its unique chemical properties.

Chemical Structure and Properties: Triethanolamine has the chemical formula C6H15NO3 and consists of three hydroxyethyl groups (-CH2CH2OH) attached to an amine group (-NH2). It is a tertiary amine and features both alkaline and alcohol functional groups, giving it amphiphilic properties. TEA is soluble in water and miscible with most organic solvents.

Synthesis and Production: Triethanolamine is synthesized through the reaction between ethylene oxide and aqueous ammonia or ethanolamine under controlled conditions. The reaction proceeds in multiple steps, resulting in the formation of TEA, which is then purified and isolated for commercial use. Industrial-scale production of TEA involves rigorous quality control measures to ensure product purity and consistency.

Industrial Applications:

1. Surfactants and Emulsifiers: Triethanolamine is widely used in the production of surfactants and emulsifiers for various applications, including cosmetics, personal care products, detergents, and industrial cleaners. Its amphiphilic nature allows it to function as a stabilizer, wetting agent, and dispersant in formulations.
2. Metalworking Fluids: TEA is employed as a corrosion inhibitor and pH buffer in metalworking fluids, such as cutting fluids and grinding coolants. It helps maintain the stability and lubricity of these fluids, thereby improving machining performance and prolonging tool life.
3. Textile Processing: In the textile industry, triethanolamine is utilized as a leveling agent, dyeing auxiliary, and pH adjuster in dyeing and printing processes. It helps ensure uniform dye penetration and color development on fabric surfaces.
4. Polyurethane Production: TEA serves as a catalyst and pH adjuster in the production of polyurethane foams, coatings, adhesives, and sealants. It facilitates the polymerization reaction between polyols and isocyanates, leading to the formation of polyurethane polymers with desired properties.
5. Gas Treating Agents: Triethanolamine is used as a scrubbing agent for the removal of acidic gases, such as carbon dioxide (CO2) and hydrogen sulfide (H2S), from natural gas, synthesis gas, and refinery streams. It reacts with acidic components to form stable salts, preventing corrosion and environmental pollution.

Consumer and Personal Care Products: Triethanolamine is commonly found in various consumer and personal care products, including:

1. Cosmetics: TEA is used in cosmetics formulations, such as creams, lotions, shampoos, and hair conditioners, as a pH adjuster, emulsifier, and thickening agent.
2. Pharmaceuticals: Triethanolamine may be included in pharmaceutical formulations as a solubilizer, buffering agent, or emulsifying agent in oral, topical, and parenteral dosage forms.
3. Household Products: TEA is present in household items like dishwashing liquids, laundry detergents, and surface cleaners as a surfactant and pH adjuster.

Safety Considerations: Triethanolamine is generally regarded as safe for use in consumer products when used in accordance with recommended guidelines. However, prolonged or excessive exposure to TEA may lead to potential health hazards, including skin irritation, allergic reactions, and respiratory irritation. Proper handling, storage, and use of TEA, along with adherence to safety precautions and regulations, are essential to minimize risks to human health and the environment.

Regulatory Status and Handling: Triethanolamine is subject to regulatory oversight by governmental agencies and international organizations to ensure its safe handling, storage, and use. Manufacturers, distributors, and users of TEA are required to comply with applicable regulations, labeling requirements, and safety guidelines to protect human health and the environment.
