Question 5

What are the advantages of Dodecylamine Polyoxyethylene Ether AC-1205 compared to other similar products?

Accepted Answer

Dodecylamine Polyoxyethylene Ether AC-1205 achieves a golden balance between wettability, emulsifying power, and chemical compatibility thanks to its precise 5EO chain length, balanced HLB value, and unique dual ionic characteristics, making it a highly competitive multifunctional nonionic surctant. Detailed Description The core advantage of Dodecylamine Polyoxyethylene Ether AC-1205 (CAS: 26635-75-6) lies in its "precision structure" formed by the addition of 5 moles of ethylene oxide (EO). This structure endows the product with the most balanced performance within its series. Compared to similar products with shorter EO chains (e.g., AC-1202), AC-1205 significantly improves water solubility and emulsifying ability; while compared to products with longer EO chains (e.g., AC-1215), it retains stronger wetting and penetrating power and ster intercial migration speed. This balance makes AC-1205 particularly outstanding in application scenarios requiring both "rapid spreading" and "stable emulsification." Another key advantage is its excellent pH responsiveness. Under normal conditions, AC-1205 behaves as a standard nonionic surctant with excellent formulation compatibility. However, in acidic media, the tertiary amine group in its molecular structure rapidly protonates, exhibiting cationic characteristics. This "smart conversion" capability, which ordinary nonionic or anionic surctants do not possess, allows AC-1205 to adsorb on metal surces to form a protective film, playing a unique role in oilfield acidizing corrosion inhibitor synergism and rust prevention/lubrication in metalworking fluids. Additionally, its high purity of over 97%, extremely low free alcohol content, and excellent chemical tolerance ensure the long-term stability of formulations under extreme conditions, reducing the risk of side reactions.

Textile High-Temperature Leveling Agents: In high-temperature and high-pressure dyeing of synthetic fibers such as polyester, AC-1205, with its high cloud point (≥60℃) and low foaminess, maintains stable dispersing performance at high temperatures, effectively migrating dyes and preventing color spots. Moreover, its cationic characteristics provide certain fiber affinity, reducing dye waste. Metalworking and Industrial Cleaning: In cutting fluids, AC-1205 not only provides lubrication and dispersion functions but also forms an adsorption film on metal surces under acidic conditions, offering auxiliary rust prevention. In heavy-duty degreasers, its strong penetrating power quickly penetrates and emulsifies heavy oils, while maintaining low foam for easy high-pressure spray cleaning. Oilfield Chemicals: In crude oil demulsification and acidizing corrosion inhibitor formulations, AC-1205 serves as an efficient intercial active component and corrosion inhibitor synergist, benefiting from its balanced HLB value and responsiveness to acidic environments. Precautions Personal Protection: According to GHS classification, this product causes skin and serious eye irritation (H315, H319). Safety goggles and protective gloves must be worn during handling, and the operating area should be well ventilated. Storage Conditions: Store sealed in a cool, dry place, with ambient temperature recommended between +5°C and +35°C. Avoid prolonged contact with strong acids or bases to maintain optimal product activity. Formulation Application: As an emulsifier with certain lipophilicity, it can be used in combination with other high-HLB emulsifiers in formulation design to achieve optimal emulsification stability. It is recommended to fully utilize its cationic characteristics in acidic formulations for specific functions.

Question 8

How to use Dodecylamine Polyoxyethylene Ether AC-1205? What is the recommended dosage?

Accepted Answer

There is no fixed dosage for Dodecylamine Polyoxyethylene Ether AC-1205; it must be determined through experiments based on specific application scenarios and formulation systems. Typical recommended dosages in various fields typically range from 1% to 15%. Detailed Description Dodecylamine Polyoxyethylene Ether AC-1205 (Guoli Chemical model AC-1205) is a nonionic surctant prepared by adding 5 moles of ethylene oxide to dodecylamine as a starting agent, with an HLB value of approximately 10.8. It exhibits nonionic properties under conventional conditions and is easily dispersed or soluble in water; when the system switches to an acidic environment, the amine group undergoes protonation and exhibits cationic characteristics, making it excellent in emulsification, dispersion, wetting, and antistatic performance. Due to the dual properties of this product, both nonionic and cationic (under acidic conditions), its usage method is relatively flexible. It can usually be added directly—slowly adding the product to the aqueous or oil phase while stirring to ensure thorough mixing; it can also be pre-diluted with warm water (approximately 30~40°C) to form a solution before adding to the formulation system for more uniform dispersion. In formulations such as acidic cleaners or metalworking fluids, it is recommended to first adjust the pH to weakly acidic with acid to fully stimulate its cationic adsorption performance. Recommended Dosage in Various Application Fields The following recommended dosages are based on application information from the Guoli Chemical product database and common industry experience, with data sources from product technical parameters (such as HLB value 10.8, tertiary amine content ≥95%, surce tension approximately 29 mN/m, etc.).The specific optimal dosage must be confirmed through small-scale testing and sample preparation. Application FieldSpecific UseRecommended Dosage (wt%) Pesticide EmulsifierEmulsifiable concentrate, emulsion in water, dispersible oil suspension3%~10% Textile Printing and Dyeing AuxiliariesHigh-temperature leveling agent, antistatic agent, soaping agent1%~5% (working solution) Daily ChemicalsShampoo, conditioner, softener conditioning component0.5%~3% Industrial Hard Surce CleanersHeavy-duty degreaser, vehicle cleaner2%~8% Metalworking FluidsWater-based cutting fluid, grinding fluid additive1%~5% Pigment DispersantPaint, color paste, ink dispersion5%~15% of pigment weight Crude Oil DemulsifierOilfield gathering and transportation demulsification, desalting and dewatering50~500 ppm (based on crude oil weight) Application Recommendations Since the amine value of AC-1205 is 126~135 mg KOH/g and its tertiary amine content is high, it can fully utilize its cationic adsorption advantage in acidic systems. In metalworking fluids and acidic cleaners, it is recommended to first adjust the pH of the system to 4~6 with a small amount of organic acid (such as citric acid or acetic acid) to positively charge the molecules, enhancing their adsorption film-forming ability and anti-rust effect on metal surces. In pesticide formulations, its HLB value of 10.8 can be used to compound with nonionic emulsifiers to broaden the emulsification window and improve the stability of the emulsion under hard water and high electrolyte conditions. Precautions Protective Requirements: This product causes skin irritation (H315) and serious eye irritation (H319). Nitrile rubber gloves and chemical safety goggles must be worn during operation. Dissolution and Dispersion: The product has high viscosity at low temperatures (approximately 150 mPa·s at 25°C). It is recommended to preheat it appropriately (not exceeding 40°C) before use for easier flow and measurement. Addition Sequence: Avoid direct mixing with high-concentration strong alkalis in the formulation. First, add slowly to the aqueous phase under stirring conditions to ensure uniform dispersion, then add other components. Environmental Safety: This product is harmful to aquatic life with long-lasting effects (H412). Waste liquid containing this product must not be discharged directly into sewers or surce waters; it must be disposed of according to hazardous waste regulations.
