Tetradecanedioic Acid used in many
industry applications

Tetradecanedioic acid, also known as tetradecanedioate or dodecanedioic acid, is a dicarboxylic acid with various industrial applications. Here are some of its main uses:

1. Corrosion Inhibitor: Tetradecanedioic acid is employed as a corrosion inhibitor in metalworking fluids, lubricants, and cooling water systems. It forms a protective film on metal surfaces, preventing corrosion caused by exposure to corrosive environments, such as aqueous solutions and atmospheric moisture.
2. Plasticizer: It is utilized as a plasticizer in polymer formulations to improve flexibility, durability, and processability of plastics and elastomers. Tetradecanedioic acid can reduce the glass transition temperature of polymers and increase their softness without compromising mechanical properties.
3. Antioxidant: Tetradecanedioic acid exhibits antioxidant properties and is used in the stabilization of organic materials against oxidative degradation. It can scavenge free radicals and inhibit chain reactions associated with oxidation processes, thereby extending the shelf life and performance of various industrial products, including polymers, coatings, and lubricants.
4. Corrosion Resistant Coatings: It is incorporated into coatings and paints as a corrosion-resistant additive to enhance the protective properties of the coating system. Tetradecanedioic acid can improve adhesion, barrier properties, and chemical resistance of coatings, providing long-term protection against corrosion and environmental degradation.
5. Adhesive Formulation: Tetradecanedioic acid is used in the formulation of structural adhesives and sealants for bonding a wide range of substrates, including metals, plastics, ceramics, and composites. It serves as a curing agent or crosslinker in epoxy and polyurethane adhesives, providing strong and durable bonds with excellent adhesion and chemical resistance.
6. Textile Auxiliaries: It finds applications in the textile industry as a dye fixing agent, flame retardant, and antistatic agent. Tetradecanedioic acid can improve the color fastness and wash resistance of dyed fabrics by forming stable complexes with dyes. Additionally, it imparts flame retardant properties to textiles and reduces static electricity buildup, enhancing the comfort and safety of textile products.
7. Personal Care Products: Tetradecanedioic acid is used in the formulation of personal care products, such as cosmetics, skincare, and hair care products. It can act as a moisturizing agent, emollient, or pH adjuster in creams, lotions, and shampoos, providing hydration and conditioning effects to the skin and hair.
8. Pharmaceutical Intermediates: It serves as an intermediate in the synthesis of pharmaceutical compounds, including drugs, agrochemicals, and specialty chemicals. Tetradecanedioic acid can undergo various chemical reactions, such as esterification, amidation, and oxidation, to produce functionalized derivatives with specific properties and functionalities.
9. Surfactants and Emulsifiers: Tetradecanedioic acid derivatives are used as surfactants and emulsifiers in various industrial applications, including detergents, cleaning products, and agricultural formulations. They can reduce surface tension, improve wetting and spreading properties, and stabilize emulsions, leading to enhanced performance and efficacy of formulated products.
10. Polymer Additive: It is employed as an additive in polymer formulations to modify properties and performance of polymers. Tetradecanedioic acid can act as a chain extender, crosslinker, or compatibilizer in thermoplastic and thermosetting polymers, leading to improvements in mechanical strength, dimensional stability, and processability of polymer materials.
