Description

Fatty Acids, C7-9-Branched are a defined mixture of synthetic, branched-chain carboxylic acids, primarily used as versatile intermediates and performance modifiers in industrial formulations. Their unique branched structure provides distinct properties compared to linear fatty acids, such as enhanced solubility, lower viscosity, and improved stability, which are critical for high-performance applications. This product is essential for manufacturers in the lubricant, plasticizer, and specialty chemical industries seeking to tailor the physical characteristics of their end products.

Application

• Lubricant & Metalworking Fluid Additives: Acts as a friction modifier, corrosion inhibitor, and base stock component for synthetic lubricants and cutting fluids.
• Plasticizer & Polymer Intermediate: Used in the synthesis of esters and polyol esters that serve as plasticizers for PVC and other polymers, or as monomers for specialty resins.
• Surfactant & Emulsifier Synthesis: Serves as a hydrophobic feedstock for producing branched-chain surfactants, offering improved wetting and emulsifying properties in detergents and agrochemicals.
• Cosmetic & Personal Care Ingredients: Employed in the manufacture of emollients, thickeners, and specialty esters for skin care and cosmetic formulations.
• Fuel & Lubricant Additive Packages: Functions as a component in additive packages for fuels and engine oils to improve cleanliness and performance.
• Chemical Synthesis & Catalysis: Utilized as a building block in organic synthesis and as a ligand or precursor in various catalytic processes.

Quality Control

Our Fatty Acids, C7-9-Branched are produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency and meets defined specifications for acid value, saponification value, color, and moisture content. Certificates of Analysis (COA) are provided with every shipment, documenting key parameters to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizers, bases, and heat sources. For long-term storage, consider under an inert atmosphere (nitrogen blanket) to minimize oxidation.
