Question 5

What are the advantages of Stearylamine Polyoxyethylene Ether AC-1802 compared to other similar products?

Accepted Answer

The core advantage of AC-1802 lies in its extremely low EO addition number (2EO), which brings high lipophilicity, strong emulsifying power, and the unique molecular structure that can be converted between nonionic and cationic Detailed Explanation In the series of stearylamine polyoxyethylene ether products from Guoli Chemical, the main difference between AC-1802 (2EO) and AC-1820 (20EO), AC-1830 (30EO) lies in the number of ethylene oxide (EO) additions. AC-1802 adds only 2 EO units, resulting in a small molecular weight and a very high proportion of lipophilic groups (stearylamine long carbon chain), which gives it an extremely low HLB value (approximately 4-5), providing irreplaceable advantages in water-in-oil (W/O) emulsion systems. Unlike the high-EO series products that are only suitable for oil-in-water (O/W) systems, AC-1802 can efficiently emulsify non-polar oils such as mineral oil, white oil, and silicone oil, making it a core choice for preparing water-in-oil creams, industrial emulsified oils, and textile oil agents. Another key differentiating advantage of AC-1802 is the protonatable characteristic of its amine group. Due to the short EO chain, the steric hindrance of the amine group is small, and under acidic conditions, it can quickly protonate into a cationic type, exhibiting strong adsorption capacity on negatively charged substrates (such as metal surces, textile fibers, and mineral particles). This property makes AC-1802 much more efficient than high-EO AC-1820 and AC-1830 in applications such as mineral flotation collection, metal surce adsorption and corrosion inhibition, and textile softening and antistatic treatment—the latter two, due to the long EO chain wrapping the amine group, have significantly weakened cationic properties and reduced adsorption efficiency. Additionally, in the field of plastic antistatic, the low molecular weight of AC-1802 allows it to migrate more easily to the polymer surce to form a conductive layer, resulting in ster onset of action compared to high molecular weight similar products; in daily chemical conditioning formulations, its short EO chain leads to higher adsorption and deposition on hair and skin, providing more direct conditioning effects. In terms of chemical stability, AC-1802, like high-EO products, tolerates hard water, acids, and bases, adapting to complex industrial environments. Technical Parameter Comparison Parameter Item AC-1802 (2EO) AC-1820 (20EO) AC-1830 (30EO) CAS No. 26635-92-7 26635-75-6 26635-75-6 Molecular Formula C₂₂H₄₇NO₂ C₅₈H₁₁₉NO₂₀ C₁₈H₃₉N·(C₂H₄O)₃₀ (average) Appearance White to slightly yellow waxy solid Light yellow to yellow Pale yellow to yellow HLB Value (estimated) Approx. 4-5 Approx. 15-16 Approx. 16-17 Water Solubility Insoluble in water, dispersible in oil Easily soluble in water Easily soluble in water Lipophilicity Extremely high Medium Low Cationic Adsorption Capacity (acidic system) Extremely strong Relatively weak Weak Note: HLB values are estimates based on EO content. For actual measured data, please consult the technical department of Guoli Chemical. Application Recommendations Select the appropriate EO number product according to your specific needs: When preparing water-in-oil (W/O) emulsions, emulsifying high-concentration mineral oils, or industrial oil-based formulations, AC-1802 is the first choice; its low HLB value ensures efficient emulsification of non-polar oils. As a mineral flotation collector, AC-1802's short EO chain and strong cationic adsorption characteristics can significantly improve the hydrophobicity and recovery rate of target minerals, outperforming high-EO similar products. As an internal antistatic agent for plastics, AC-1802 has st migration speed and quick onset of action, suitable for polyolefin (PE, PP) processing. In daily chemical conditioners and shampoos as a conditioning agent, AC-1802 offers high adsorption and deposition, providing direct softening effects; if a water-soluble emulsifier is required, AC-1820 or AC-1830 is recommended. If formulating oil-in-water (O/W) emulsions or emulsifiers for aqueous systems, choose high-EO AC-1820 or AC-1830, which are completely soluble in water with high cloud points, making them more suitable for water-based formulations. Precautions Safe Handling: AC-1802 is irritating to skin and eyes (Category 2/2A). Protective gloves and goggles must be worn during operation, and skin should be thoroughly washed after work. Environmental Impact: Harmful to aquatic life with long-lasting effects (H412). Waste disposal must comply with local regulations; do not discharge into water bodies. Formulation Compatibility: AC-1802 exhibits cationic properties in acidic systems. Avoid large simultaneous use with anionic surctants to prevent precipitation or antagonistic effects. Storage Conditions: Store sealed in a cool, dry place between 10°C and 40°C. This product is a waxy solid; prevent melting and caking due to high temperature.

Question 8

How to use Stearyl Amine Polyoxyethylene Ether AC-1802? What is the recommended dosage?

Accepted Answer

The usage method of Stearyl Amine Polyoxyethylene Ether AC-1802 varies by application area, and the dosage and dispersion method need to be adjusted according to specific processes and target effects. Detailed Description Stearyl Amine Polyoxyethylene Ether AC-1802 is a nonionic surctant (CAS: 26635-92-7) that appears as a white to slightly yellow waxy solid at room temperature. Its melting point is 45~50°C, so it usually needs to be melted or dissolved before use. The most convenient method is to preheat and melt it, then slowly add it to the system under stirring; or dissolve it in hot water or organic solvents (such as ethanol, isopropanol) to prepare a solution of a certain concentration before use. This ensures uniform dispersion in the system, fully exerting its emulsifying, antistatic, or conditioning properties. The ionic characteristics of this product vary with pH: it is nonionic in neutral or alkaline environments; in acidic systems, the amine group protonates and becomes cationic. Therefore, when needing to enhance its antistatic property or adsorption to negatively charged substrates, the system can be appropriately adjusted to acidic (e.g., pH 4~6) to leverage its cationic characteristics for better performance. Recommended Dosages in Various Fields The national standard product database does not have precise dosages for each application field. The following are general recommended ranges based on the chemical characteristics of the product and industry application practices. Actual dosages need to be determined through process trials: Application FieldRecommended Dosage (Percentage of Total Formulation or Material Weight)Usage Instructions Internal Antistatic Agent for Plastics/Synthetic Fibers0.3% ~ 1.5%Pre-mix with resin, or add via side feeding, using screw shear to ensure full dispersion. Textile Dyeing and Printing Leveling/Softening Agent0.5% ~ 2.0% (Based on bric Weight)When used in acidic dye baths, the cationic characteristics can enhance leveling of dyes and softening effect on fibers. Personal Care (Shampoo/Conditioner) Conditioning Agent0.2% ~ 1.0%Add during the cooling phase of the formulation; weakly acidic formulations (pH 4~5.5) can maximize its adsorption and conditioning capability. Industrial Emulsifying Oil/Metalworking Fluids2% ~ 5% (As Main Emulsifier Component)Compounding with other emulsifiers such as oleic acid soap yields better results, enhancing emulsification and corrosion inhibition of base oils. Pesticide Emulsifiable Concentrate/Coating/Ink Dispersant1% ~ 5%Used for emulsifying oil phase or wetting and dispersing pigments to prevent particle agglomeration and sedimentation. Mineral Flotation Collector0.05 ~ 0.5 kg/ton of Raw OreDosage depends on ore grade and pulp density; need to determine through flotation process condition trials. Application Recommendations Dispersion/Dissolution Tips: It is recommended to pre-dissolve AC-1802 in hot water above 60°C with stirring, or melt and add it to the oil phase before mixing with other components. Due to the product's HLB value of only 4.5, its hydrophilicity is relatively weak. When used alone as an oil-in-water (O/W) emulsifier, it usually needs to be compounded with a high-HLB emulsifier for better emulsion stability. Compounding Synergy: In metalworking fluids or industrial cleaning formulations, it can be compounded with anionic surctants (such as sodium petroleum sulfonate) or other nonionic surctants to achieve synergistic effects, enhancing the system's emulsification, detergency, and rust prevention capabilities. Precautions Personal Protection: This product is a skin and eye irritant (Hazard Category 2/2A). Wear chemical-resistant gloves and protective goggles during operation to avoid direct contact. Storage: Store sealed in a cool, ventilated place; recommended storage temperature is between 10°C and 40°C; keep away from strong oxidizing agents and strong acid environments. Environmental Safety: Harmful to aquatic life (Aquatic Hazard Category 3). Industrial wastewater containing this product must not be discharged directly into water bodies; it must be properly treated.

Textile Leveling: Recommended dosage is 1% to 3% of the bric weight (based on bath ratio), with use under weakly acidic conditions to enhance leveling effect. Daily Chemical Formulations: Recommended addition of 0.5% to 2% in shampoos and conditioners; optimal conditioning effect under weakly acidic conditions (pH 4 to 6). Industrial Emulsification: When used as an emulsifier, recommended dosage is 3% to 8% of the oil phase weight; stable emulsions can be prepared using inversion or direct emulsification methods. Metalworking Fluids: Recommended addition amount is 5% to 15% of the concentrate, combining emulsifying and corrosion inhibition functions. Mineral Flotation: As a collector, typical dosage is 100 to 500 g per ton of ore; specific dosage should be determined based on ore properties through flotation tests. (The above recommended dosages are based on application experience from Guoli Chemical; actual dosages need to be adjusted according to specific formulations and process conditions.) Precautions Ionic Character Control: To utilize its cationic properties (e.g., enhanced adsorption, antistatic effect), adjust the system pH to the acidic range. Dissolution Operation: The product is a paste or waxy solid at room temperature; it is recommended to preheat it to 40 to 50°C to melt before feeding for easier dispersion and dissolution. Safety Protection: This substance is a skin irritant (Category 2) and eye irritant (Category 2A); protective gloves and goggles must be worn during handling. In case of accidental contact, immediately rinse with plenty of water. Environmental Requirements: Harmful to aquatic organisms (Category 3); wastewater containing this substance must be properly treated before discharge; direct discharge into water bodies is prohibited. Storage Conditions: Recommended storage temperature is 10°C to 40°C; keep container sealed, away from strong oxidizers and strong acidic environments; prevent freezing or prolonged exposure to high temperatures.

Question 10

What are the physicochemical technical parameters of Stearylamine Polyoxyethylene Ether AC-1802?

Accepted Answer

The physicochemical technical parameters of Stearylamine Polyoxyethylene Ether AC-1802 (CAS: 26635-92-7) cover core data such as basic physical properties, chemical indicators, and surce activity. The following contents are all derived from the product database of Guoli Chemical. Detailed Description Stearylamine Polyoxyethylene Ether AC-1802, chemically named N,N-Bis(2-hydroxyethyl)stearylamine, has the molecular formula C22H47NO2 and a molecular weight of 357.6. This product is a nonionic surctant prepared by ethoxylation reaction using stearylamine as a starting agent. It appears as a white to slightly yellow waxy solid at room temperature, with a melting point of 45~50°C. Its molecular structure contains both ether bonds and tertiary amine groups, endowing it with unique intercial activity and multifunctional application potential—exhibiting nonionic characteristics under neutral and alkaline conditions, and converting to cationic type after amine group protonation in acidic systems. Due to its HLB value of only 4.5, this product has strong lipophilicity and limited dispersibility in water (dispersible in cold water, soluble in hot water and organic solvents), but it performs excellently in emulsification, dispersion, and antistatic applications. The product has a surce tension of 30 mN\/m and a critical micelle concentration (CMC) of 1×10-4 mol\/L, enabling efficient intercial regulation at very low dosages, making it a high-quality water-in-oil emulsifier and industrial dispersant intermediate.
