Description

Fatty Acids, Tall-Oil, Sodium Salts CAS NO 61790-45-2 are the sodium salts derived from tall oil fatty acids, a versatile class of anionic surfactants and emulsifiers. This product is valued for its excellent surface-active properties, which are critical for stabilizing formulations and reducing interfacial tension. It is an essential raw material for manufacturers in the soap and detergent, textile processing, metalworking, and emulsion polymerization industries, where reliable performance and consistent quality are paramount.

Application

• Soap and Detergent Manufacturing: Acts as a primary surfactant and foaming agent in industrial and institutional cleaning products.
• Textile Processing: Used as a scouring agent, emulsifier, and softener in fiber treatment and dyeing processes.
• Metalworking Fluids: Serves as an emulsifier and corrosion inhibitor in soluble oils and coolants.
• Emulsion Polymerization: Functions as a key surfactant in the production of synthetic rubbers (e.g., SBR) and latex paints.
• Paper Sizing: Utilized in the production of paper and cardboard to improve water resistance.
• Agricultural Adjuvants: Employed as a wetting and spreading agent in pesticide and herbicide formulations.
• Leather Processing: Used in fatliquoring and softening of leather.
• Oilfield Chemicals: Acts as an emulsifier and viscosity modifier in drilling muds and other oilfield applications.

Quality Control

Our Fatty Acids, Tall-Oil, Sodium Salts are produced under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is tested against key parameters including acid value, saponification value, and fatty acid composition. A Certificate of Analysis (COA) detailing these specifications is provided with every shipment 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 ambient temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
