1. Basic Product Information

• Product Category: Non-ionic surfactant (tallow amine ethoxylate type)
• Chemical Structure: Formed by the addition reaction of tallow amine with 15 moles of ethylene oxide (EO). Its molecular structure includes oil-loving tallow amine alkyl chains and water-loving polyoxyethylene ether chains.
• Core Functions: Combines emulsifying, dispersing, wetting, and penetrating properties. Due to the synergistic effect of amino groups and ether bonds in the molecule, it maintains stable surface activity even in high-electrolyte environments (such as pesticide emulsifiable concentrates and industrial cleaning solutions).

2. Key Properties and Characteristics

2.1 Physicochemical Parameters

2.2 Core Functional Advantages

• High Electrolyte Stability: It maintains emulsifying and dispersing effects even in systems containing high-concentration salts and pesticide active ingredients (e.g., emulsifiable concentrates with 20% active ingredients), solving the problem of traditional surfactants becoming inactive under strong electrolytes.
• Efficient Wetting and Penetration: It can significantly reduce liquid surface tension (to 30-35 mN/m), enhancing the adhesion and penetration of pesticide solutions on crop leaf surfaces. In industrial cleaning, it can quickly strip stubborn oil stains.
• Strong Formulation Compatibility: It can be compounded with anionic and cationic surfactants, and is compatible with most functional additives (e.g., preservatives, thickeners), making it suitable for complex formulation systems.
• Good Environmental Adaptability: It is resistant to acids and alkalis (stable in pH 5-10 range) and hard water, maintaining consistent performance under different water quality and process conditions.

3. Main Application Fields

3.1 Pesticide Formulations

• Used as an emulsifier and wetting agent in dosage forms such as emulsifiable concentrates (EC) and microemulsions (ME). It is compatible with various pesticide active ingredients including organophosphates, pyrethroids, and triazoles, with a typical addition amount of 5-15%.
• It can improve the dispersion stability of poorly soluble pesticides (e.g., trifluralin, acetochlor), extend the storage life of formulations, and enhance field efficacy (e.g., increasing the adhesion rate of pesticide solutions on crop leaves with waxy layers).

3.2 Industrial Cleaning

• Applied in metalworking fluids (semi-synthetic cutting fluids) as an emulsifier and wetting agent. It removes metal chips and heavy oil stains efficiently while providing lubrication.
• Suitable for oilfield chemicals (e.g., drilling fluid emulsifiers) to help stabilize oil-water systems and improve drilling efficiency.

3.3 Textile Dyeing and Finishing

• Used in textile pre-treatment (desizing, scouring) to assist in removing oil and wax from fiber surfaces with minimal fiber damage.
• Can act as a leveling agent in dye formulations to improve dyeing uniformity and reduce the risk of color spots.

3.4 Other Fields

• Asphalt Emulsification: Used as an emulsifier in modified asphalt production to help form a stable oil-in-water emulsion system.
• Ore Flotation: Applied in the flotation of non-ferrous metal ores (e.g., copper, zinc ores) to improve the separation efficiency of minerals and gangue.

4. Usage Precautions

• Storage: Store in a sealed container in a cool and dry place, avoiding high temperatures (>80℃) and direct sunlight. The typical shelf life is 12 months.
• Operation: Avoid direct contact with skin or eyes. In case of accidental contact, rinse immediately with plenty of clean water.
• Compounding: A small-scale test is recommended to determine the compounding ratio, as compatibility varies across different systems.
• Concentration Control: The addition amount is 5-15% in the pesticide field, and can be adjusted to 10-30% in the industrial cleaning field based on cleaning requirements.
