Triethanolamine

　　Main Uses

　　Surfactants and Daily Chemicals:

　　Widely used in cosmetics (such as face creams, shampoos, shower gels) and detergents as an emulsifier, humectant, and pH regulator. Its weak alkalinity can neutralize acidic components in the formula and stabilize the product's pH, while the hydrophilicity of the hydroxyl group enhances skin moisturization.

　　Used to prepare fatty acid soaps or detergents to improve the foaming and stability of products.

　　Industrial Fields:

　　Metal Processing: Used as a component in metal cutting fluids and rust inhibitors, utilizing its chelating properties to adsorb onto metal surfaces and prevent oxidation and rust; can also be used as an additive in electroplating solutions to improve coating uniformity.

　　Coatings and Inks: Used as a neutralizing agent to adjust the pH of water-based coatings, enhancing their stability and fluidity; it can also promote pigment dispersion and improve coating adhesion.

　　Polyurethane Synthesis: Used as a chain extender and catalyst, participating in the synthesis of polyurethane foams and elastomers to regulate product hardness and toughness.

　　Textile Industry: Used as a fiber softener and antistatic agent to improve the hand feel and antistatic properties of fabrics.

　　Pharmaceuticals and Agriculture:

　　In pharmaceuticals, used as a buffer (to adjust the pH of medicinal solutions) or a co-solvent to help dissolve poorly soluble drugs; can also be used in the preparation of local anesthetics to alleviate pain during injections.

　　In agriculture, used as a fertilizer additive to promote plant absorption of trace elements; or as a pesticide emulsifier to improve the stability of efficacy.

　　Other Applications: Used for natural gas desulfurization, reacting with hydrogen sulfide to form stable salts and reducing sulfur content in the gas.

　　Used as a concrete additive to improve the plasticity and strength of concrete.

　　Used as a basic catalyst or intermediate in organic synthesis, participating in reactions such as transesterification and condensation.
