Triethanolamine (CAS 102-71-6) is a multifunctional ingredient widely used in cosmetic formulations. TEA enhances both the performance and sensory qualities of personal care and hygiene products. It regulates pH levels, supports the formation of stable emulsions, and boosts the effectiveness of other active ingredients in the formula. Thanks to its chemical structure, triethanolamine works well in creams, gels, lotions, and many other skincare products. It is valued not only for its functionality but also for its stability and versatility.

• Triethanolamine as a pH regulator in cosmetics: 2;2′;2”-nitrilotriethanol helps maintain the optimal pH level of cosmetic products, which directly impacts their safety, stability, and shelf life. It is most commonly used in emulsions, gels, toners, and shaving products – especially in combination with fatty acids, with which it forms stable salts that enhance product performance.
• Triethanoloamine as an emulsifier and emulsion stabilizer: Thanks to its hydroxyethyl groups, triethanoloamine facilitates the formation of uniform oil-in-water emulsions. It enhances emulsion stability, improves texture, and helps prevent separation. You’ll find it in a wide range of products, including creams, milks, lotions, and hair styling formulations.

Triethanolamine also serves as an effective emulsifier and stabilizer across multiple industries. Its chemical structure allows it to combine aqueous and oily phases, promoting the formation of uniform and stable emulsions.

2;2′;2”-nitrilotriethanol is used as an emulsifier and stabilizer in the production of cosmetics and other products, including:

• Household chemicals: In cleaning agents and detergents, triethanolamine stabilizes mixtures and improves viscosity. This results in more uniform products that spread more easily and retain their functional properties even during long-term storage.
• Paints and oils: In water-based paints, triethanolamine plays a dual role – regulating pH and stabilizing pigment and binder dispersions. It helps prevent paint separation and improves flow properties, directly contributing to coating quality.
• Adhesives, lubricants, and technical oils: In industrial formulations, triethanolamine helps create stable emulsions and prevents sedimentation of ingredients. As a result, the final products are more homogeneous and effective in performance – for example, in anticorrosive, cooling, or lubricating applications.
• Construction chemicals: Triethanolamine supports the stability of polymer emulsions used as additives in tile adhesives, plasters, and sealing coatings. It facilitates the blending of water-based and polymer components, improving workability and enhancing the durability of the final product.

• In the metallurgical industry and technical chemistry, triethanolamine is used as a chelating agent for metal ions, helping to protect equipment from corrosion and stabilize cooling and lubricating fluids.
• In paper chemistry, it can act as a sequestrant, preventing the precipitation of metals from process water.
