What is Tallow Amine Ethoxylate CAS 61791-26-2?

CAS 61791-26-2 identifies ethoxylated tallow alkyl amines, also called tallow amine ethoxylate or polyoxyethylene tallow amine. It is a non-ionic or cationic-leaning surfactant produced by reacting tallow amine with ethylene oxide.

What are the main applications of tallow amine ethoxylate?

It is used as an agrochemical adjuvant, spreader, and emulsifier; as a leveling agent, lubricant, and antistatic in textile and leather processing; and as a corrosion inhibitor or emulsifier in oilfield and industrial cleaning formulations.

How does the degree of ethoxylation affect the product?

The number of ethylene oxide units controls the HLB value, water solubility, cloud point, and physical form. Lower EO grades tend to be oil-soluble liquids, while grades around 10 EO and above become water-soluble liquids or pastes.

What specifications apply to the standard 15EO grade?

The standard 15EO grade is a yellowish liquid to semi-solid paste with an amine value around 40-55 mg KOH/g, tertiary amine content typically at least 97%, water content no more than 1.0%, and HLB about 12-14.

Is this product a primary tallow amine or an ethoxylated derivative?

It is the ethoxylated derivative, not the primary tallow amine. The CAS number and product data reflect a polyoxyethylene tallow amine surfactant, which behaves differently in formulation and should not be confused with distilled tallow amine.

Tallow Amine Ethoxylate CAS 61791-26-2

Tallow Amine CAS 61791-26-2 is a versatile non-ionic surfactant derived from fatty acid sources, functioning primarily as a high-efficiency emulsifier and wetting agent in complex chemical systems. In industrial formulations, this polyethoxylated tallow amine provides critical surface activity and electrolyte stability, acting as a vital component in polyoxyethylene tallow amine based adjuvant systems for the agricultural sector. The chemical structure of tallowamine ethoxylate allows it to serve as a corrosion inhibitor in oilfield applications and a dispersing agent in textile processing, while ethoxylated tallow alkyl amine is frequently employed to enhance the penetration of active ingredients in industrial-grade cleaners. We provide bulk supply with competitive factory pricing to support global distribution, ensuring all technical requirements are met with provided MSDS, TDS, COA and we offer customized specifications regarding the moles of ethylene oxide (EO) to suit specific formulation viscosities and HLB requirements.

Applications

Agrochemical Adjuvants: Acts as a primary surfactant and spreader in herbicide formulations to improve the biological efficacy of active ingredients.
Textile & Leather Chemicals: Used as a leveling agent, lubricant, and antistatic agent in fiber processing and leather finishing.
Oilfield Chemicals: Functions as a corrosion inhibitor and emulsifier in oil extraction and refining processes to protect metal infrastructure.
Industrial Cleaners: Incorporated into heavy-duty detergents and degreasers to facilitate the removal of grease and oily contaminants from hard surfaces.

Storage & Safety

Storage: Store in a dry, cool, and well-ventilated area. Keep the container tightly closed to prevent oxidation and moisture absorption. Avoid exposure to extreme heat or open flames.
Safety Operations (PPE): Wear chemical-resistant gloves (nitrile or neoprene), safety splash goggles, and protective clothing. If handling in confined spaces, ensure adequate ventilation or use an organic vapor respirator.
Handling: This substance is typically irritating to the eyes and skin; avoid direct contact. In case of contact, rinse immediately with plenty of water.

Quality Assurance

Our manufacturing facility adheres to strict ISO 9001 quality management protocols to ensure the consistency of ethoxylation degrees and amine values across every batch. We utilize Gas Chromatography (GC) for fatty acid distribution analysis and potentiometric titration for precise amine value determination. Each production lot is validated against standardized performance benchmarks for cloud point and emulsification stability, ensuring that our technical-grade surfactants meet the rigorous demands of international B2B industrial applications.
