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 to stabilize the product's pH, while the hydrophilicity of the hydroxyl group enhances skin moisturizing effects.

　　Used in the preparation of fatty acid soaps or detergents to improve the foaming property and stability of products.

　　Industrial Field:

　　Metal Processing: As a component of metal cutting fluids and rust inhibitors, it utilizes its chelating property to adsorb onto metal surfaces to prevent oxidation and rust; it 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 coating stability and fluidity; it can also promote pigment dispersion and improve coating adhesion.

　　Polyurethane Synthesis: As a chain extender and catalyst, it participates in the synthesis of polyurethane foams and elastomers, regulating product hardness and toughness.

　　Textile Industry: Used as a fiber softener and antistatic agent to improve fabric hand feel and antistatic performance.

　　Pharmaceuticals and Agriculture:

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

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

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

　　As a concrete additive to improve the plasticity and strength of concrete.

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