Triethanolamine is a colorless, viscous liquid commonly used in various industries, including cosmetics, pharmaceuticals, and agriculture. It serves as a surfactant, emulsifier, and pH balancer, helping to stabilize products and improve their texture. In personal care products, Triethanolamine helps to blend oil and water-based ingredients, making lotions and creams smoother. While generally considered safe in low concentrations, it is important to use it according to guidelines to avoid potential skin irritation or allergic reactions.
