Distearylamine (SA86), a prominent secondary amine, is a chemical compound characterized by its amphiphilic nature and extensive hydrophobic chains. As a manufacturer and supplier, we understand the critical importance of its chemical profile for a wide array of industrial applications, from polymer stabilization to advanced materials science.

Chemically, Distearylamine is a diamine where two stearyl (octadecyl, C18) groups are attached to a nitrogen atom. This structure confers a unique set of properties. The two long, saturated alkyl chains render the molecule highly hydrophobic and contribute to significant steric hindrance, while the secondary amine group provides a site for potential functionalization and interaction with polar substances or surfaces.

The synthesis of Distearylamine typically involves sophisticated chemical processes. While specific patented routes may vary, common approaches include the reductive amination of fatty acid derivatives or the controlled alkylation of amines. The key challenge in synthesis is to achieve high purity and yield, minimizing the formation of unwanted byproducts like primary or tertiary amines. Our manufacturing processes are optimized to ensure a high-purity product, typically an off-white to pale yellow solid, with a specified content and amine value that meets industry standards.

The applications of Distearylamine (SA86) are remarkably diverse, driven by its multifaceted properties:

1. Polymer Additives: As an antioxidant and thermal stabilizer, SA86 protects polymers like PP and PE from degradation. Its ability to scavenge free radicals and interrupt oxidation chains extends the lifespan and maintains the performance of plastic materials.

2. Cosmetic and Personal Care: In this sector, SA86 functions as a suspension stabilizer, improving the texture and stability of formulations such as lotions and creams. Its amphiphilic nature helps to create stable emulsions.

3. Nanomaterials Science: Distearylamine is indispensable as a stabilizing and phase-transfer agent for nanoparticles. Its long hydrocarbon chains provide steric stabilization, preventing aggregation, and facilitate the transfer of nanoparticles from aqueous to organic phases, crucial for advanced material fabrication.

4. Corrosion Inhibition: The compound forms protective, hydrophobic films on metal surfaces, acting as an effective corrosion inhibitor in industrial systems, thereby protecting equipment and infrastructure.

5. Biomedical Applications: Derivatives of SA86 are explored in drug and gene delivery systems, particularly in liposomes and nanoparticles, leveraging its amphiphilic nature for encapsulation and targeted delivery.
