Description

Fatty Acids, Tallow CAS NO 61790-37-2 is a complex mixture of saturated and unsaturated fatty acids derived from animal tallow. This versatile raw material is valued for its lubricating properties, surfactant characteristics, and role as a chemical intermediate. It is essential for manufacturers in industries such as soap and detergent production, lubricant formulation, and polymer manufacturing.

Application

• Soap and Detergent Manufacturing: A primary feedstock for producing metallic soaps (e.g., calcium, zinc stearates) and as a surfactant base.
• Lubricants and Greases: Used as an additive and thickener to enhance lubricity and stability in industrial lubricants.
• Polymer and Plastic Industry: Acts as an internal and external lubricant, processing aid, and release agent in plastics compounding.
• Chemical Intermediate: Serves as a starting material for the synthesis of fatty acid esters, amides, and other derivatives.
• Textile and Leather Processing: Employed in softening and finishing agents for fibers and leather goods.
• Rubber Industry: Functions as an activator and processing aid in rubber vulcanization and compounding.
• Candle and Wax Blends: Used to modify the melting point and burning characteristics of candles and industrial waxes.
• Corrosion Inhibitors: A component in formulations designed to protect metal surfaces.

Quality Control

Our Fatty Acids, Tallow is produced under a stringent quality management system. Each batch is tested against key parameters including acid value, saponification value, iodine value, and color to ensure consistent performance and purity for industrial applications. Certificates of Analysis (COA) are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Due to its tendency to be easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen blanket) for long-term preservation and to minimize color degradation. Recommended storage temperature is 15-25°C.
