Dodecyl amine polyoxyethylene ether AC-1205, with its nonionic/weak cationic switching property, is widely used in agriculture, textiles, daily chemicals, industrial cleaning, metal processing, coatings, petroleum, and many other industries.
Detailed Description
AC-1205 is a nonionic surfactant produced by ethoxylation of dodecyl amine. Under normal conditions, it is nonionic, giving it excellent formulation compatibility. When the system switches to an acidic environment, the amine groups in the molecule undergo protonation, exhibiting cationic characteristics. This "nonionic-cationic intelligent switching" mechanism makes it perform excellently in emulsification, dispersion, wetting, antistatic, and other aspects, making it a key functional component in many industrial formulations.
In practical applications, the high emulsifying capacity of AC-1205 can quickly reduce oil/water interfacial tension, forming stable, fine emulsion systems. Its lasting dispersion stability effectively prevents settling, flocculation, and agglomeration of pigments and solid particles. Excellent wetting and spreading properties significantly reduce the contact angle of the working fluid on substrates such as fabrics, metals, and plastics, enhancing penetration rate and uniformity. Additionally, this product maintains stable surface activity and solubility in acid, alkali, and hard water systems, exhibiting outstanding chemical tolerance.
Overview of Industry and Process Applications
Below is a breakdown of specific application processes and functional roles of AC-1205 by industry:
1. Agrochemical Formulation Industry
- Pesticide Emulsifier: Used as a high-efficiency emulsifier in pesticide formulations such as emulsifiable concentrates (EC) and emulsion concentrates (EW) to reduce oil-water interfacial tension, improve the thermodynamic stability and dilution dispersibility of the emulsion, and ensure uniform release of active ingredients.
- Dispersible Oil Suspension (OD) Adjuvant: Provides excellent dispersion and suspension capabilities to prevent sedimentation of active ingredients.
- Tank-Mix Adjuvant: Added during field tank mixing to enhance wetting, spreading, and penetration of the spray liquid on crop leaf surfaces, improving pesticide utilization.
2. Textile and Leather Industry
- High-Temperature Leveling Agent: In high-temperature high-pressure dyeing processes of synthetic fibers (polyester, acrylic, etc.), it enhances the migration ability of dyes, reducing dyeing defects such as color streaks and spots.
- Fiber Antistatic Agent: Used in pretreatment, spinning, and finishing processes of synthetic fibers to reduce static buildup and improve fiber spinnability and hand feel.
- Soaping Agent after Dyeing: In the washing process after dyeing to remove unfixed dyes and improve color fastness.
3. Daily Chemical Industry
- Conditioner in Hair Conditioners and Shampoos: Acts as a thickening, emulsifying, and antistatic conditioning component, improving foam fineness and imparting smooth, soft touch to hair.
- Fabric Softener: Adsorbs onto fiber surfaces to provide soft, smooth tactile modification and antistatic effects.
- Hard Surface Cleaner: Used in hard surface cleaning formulations for kitchens, bathrooms, etc., enhancing detergency and surface gloss.
4. Industrial Cleaning and Metalworking Industry
- Industrial Hard Surface Cleaner: Used in formulations for vehicle cleaners, heavy-duty degreasers, etc., to penetrate and emulsify mineral oils and vegetable oils, enhancing detergency while reducing corrosiveness to metal and plastic substrates.
- Additive in Metal Cutting Fluids and Grinding Fluids: Functions as a lubricant, dispersant, and rust inhibitor in water-based cutting and grinding fluids, adsorbing onto metal surfaces to form a protective film, reducing tool wear, and inhibiting rust formation.
5. Paint, Ink, and Pigment Industry
- Pigment Dispersant: Applied in paint, ink, and color paste systems to prevent flocculation of pigment particles through steric hindrance and electrostatic stabilization mechanisms, improving color strength, storage stability, and color uniformity.
6. Petroleum and Energy Industry
- Crude Oil Demulsifier and Desalting Agent: In oilfield gathering and refinery desalting/dewatering processes, it accelerates oil-water separation of crude oil emulsions, weakens interfacial film strength, achieves rapid demulsification, and improves crude oil purification efficiency and water quality.
- Synergist for Oilfield Acidizing Corrosion Inhibitors: Used in combination with corrosion inhibitors during acidizing operations, leveraging cationic properties under acidic conditions to enhance adsorption and film formation on metal surfaces.
Application Recommendations
During formulation design, it is recommended to flexibly utilize the nonionic/cationic switching property of AC-1205 based on the pH conditions of the target system: In neutral or alkaline formulations, fully leverage its nonionic emulsifying, dispersing, and wetting functions; in acidic systems (e.g., industrial pickling, oilfield acidizing), utilize its cationic characteristics to enhance affinity and adsorption on negatively charged substrates. The recommended dosage varies by specific application, typically 0.5% to 5% of the total formulation; gradient tests are advised to determine the optimal addition level.
