Description

Disodium Dodecanedioate is the disodium salt of dodecanedioic acid, a long-chain dicarboxylate compound. This specialty chemical is valued for its role as a versatile intermediate and functional additive in high-performance formulations. It is particularly relevant for manufacturers in the polymer, personal care, and specialty chemical synthesis sectors seeking consistent quality and reliable supply.

Application

• Polymer Industry: As a monomer or co-monomer in the synthesis of polyamides (nylons), polyesters, and other specialty polymers, contributing to material strength and thermal properties.
• Personal Care & Cosmetics: Used as a buffering agent, pH adjuster, or a precursor for emollient esters in creams, lotions, and other skincare products.
• Lubricants & Greases: Serves as a component or precursor in the formulation of synthetic lubricants and high-temperature greases.
• Corrosion Inhibitors: Acts as an intermediate in the production of corrosion-inhibiting additives for industrial fluids and coatings.
• Chemical Synthesis: A key building block for organic synthesis, including the production of plasticizers, adhesives, and other fine chemicals.
• Detergents & Surfactants: Can be utilized as a precursor for anionic surfactants with good biodegradability profiles.

Quality Control

Our Disodium Dodecanedioate is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and physical properties. Certificates of Analysis (COA) documenting these results are provided with every shipment and are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
