Physical State
Chemical Composition and Properties: - Triethanolamine (TEA) is an organic compound with the chemical formula C₆H₁₅NO₃. It is a viscous, colorless to pale yellow liquid with a mild ammonia-like odor. TEA is both a tertiary amine and a triol, containing three hydroxyl groups, making it highly soluble in water and alcohol.
Industrial Applications: - Surfactant and Emulsifier: TEA is commonly used in the formulation of surfactants and emulsifiers, which are key components in detergents, soaps, shampoos, and other cleaning products. It helps to stabilize emulsions by reducing surface tension between oil and water.
- Corrosion Inhibitor: Used as a corrosion inhibitor in metalworking fluids, cooling systems, and other industrial processes to protect metal surfaces from rust and corrosion.
Cosmetic and Personal Care Uses: - pH Adjuster: TEA is used in cosmetics and personal care products, such as creams, lotions, and hair care products, to adjust and stabilize the pH. It ensures the products remain within the desired pH range for safety and efficacy.
- Emulsifying Agent: Functions as an emulsifying agent to help mix oil and water-based ingredients, providing a smooth and uniform texture in creams and lotions.
Safety and Environmental Considerations: - Toxicity and Irritation: At high concentrations (>85%), TEA can be irritating to the skin, eyes, and respiratory system. Prolonged or repeated exposure may cause skin sensitization. Proper handling, including the use of protective equipment, is essential to minimize risks.
- Regulatory Status: TEA is generally recognized as safe (GRAS) for use in specific applications within regulated limits. However, there are restrictions on its concentration in certain products due to potential concerns about nitrosamine formation, which can be carcinogenic. It is important to follow regulatory guidelines to ensure safe use.
