Question 1

Is dodecyl polyoxyethylene ether AC-1215 harmful to humans? Does it have an impact on the environment?

Accepted Answer

Dodecyl polyoxyethylene ether AC-1215 is a low-toxicity chemical, with relatively low acute toxicity, but it is irritating to the skin and eyes; it is harmful to aquatic organisms, but it is readily biodegradable and does not persist in the environment easily. Detailed Explanation The acute toxicity of dodecyl polyoxyethylene ether AC-1215 is relatively low, with an oral LD50 >2000 mg\/kg in rats and a dermal LD50 >2000 mg\/kg in rabbits, so it is not classified as an acutely toxic substance. Its main health risks are local irritation: it causes mild skin irritation (GHS skin corrosion\/irritation category 2, H315) and moderate to severe eye irritation (GHS serious eye damage\/irritation category 2, H319). Skin sensitization tests in guinea pigs show that the product is not sensitizing. Inhalation of its vapor or mist may cause respiratory tract irritation, and ingestion may cause nausea, vomiting, and other discomfort, but acute toxicity is low. In terms of the environment, the product is toxic to aquatic organisms, with an acute fish 96-hour LC50 of 1–10 mg\/L, classified as GHS aquatic hazard - long-term hazard category 3 (H412). However, the product is readily biodegradable—with a BOD\/COD ratio greater than 60% within 28 days—and has low bioaccumulation potential. It can be gradually eliminated in water and soil through biodegradation and other processes, and does not persist easily in the environment. Overall, under conditions of proper use and disposal, its environmental risks are manageable.

Question 5

What are the advantages of Dodecylamine Polyoxyethylene Ether AC-1215 compared to other similar products?

Accepted Answer

The core advantage of Dodecylamine Polyoxyethylene Ether AC-1215 (EO=15) lies in its precise EO chain length design, which endows the product with excellent water solubility, a very high HLB value (15.6), and a unique "nonionic/cationic" dual characteristic, making it significantly superior to similar products with lower EO numbers in emulsification, solubilization, and compatibility with acidic systems. Detailed Explanation In the series of dodecylamine polyoxyethylene ether products from Guoli Chemical, AC-1215 (15EO), as a product with a high molar ratio of addition, has a performance positioning that is fundamentally different from its lower EO number counterparts (such as AC-1202, AC-1205). The AC-1215 molecule introduces 15 ethylene oxide (EO) units, and the longer polyoxyethylene ether chain segment significantly enhances the hydrophilicity of the molecule. This is directly reflected in its HLB value as high as 15.6, much higher than AC-1205 (approximately 10-11) and AC-1202 (approximately 6-7), making it an efficient O/W (oil-in-water) emulsifier and solubilizer. In practical applications, this means AC-1215 can easily dissolve in cold water, and its aqueous solution remains stable at high temperatures, without the "cloud point" precipitation phenomenon observed in lower EO number products (the cloud point of AC-1215 is >100°C). Structure determines performance. The AC-1215 molecule retains both the tertiary amine group and the long-chain polyoxyethylene ether segment, which is its most unique advantage. Under normal neutral or alkaline conditions, it behaves as a stable nonionic surctant with excellent resistance to hard water, acids, and alkalis; however, in an acidic medium, its amine groups protonate and acquire a positive charge, instantly transforming into a cationic surctant. This "intelligent switching" mechanism is not possessed by ordinary tty alcohol polyoxyethylene ethers (AEO series) or pure cationic surctants. Therefore, in acidic cleaning agents or acidic metal treatment fluids, AC-1215 not only acts as a solubilizer but also utilizes its cationic properties to adsorb onto metal surces, providing additional corrosion inhibition and rust prevention functions, which are difficult to achieve with low EO number amine ethers or conventional nonionic surctants. Furthermore, the long chain segment brought by the high EO number endows AC-1215 with a lower CMC value (approximately 9×10⁻⁵ mol/L, i.e., 0.009%), much lower than that of AC-1205. This means that at extremely low usage concentrations, AC-1215 can form micelles and exert significant emulsifying and dispersing effects. Combined with its excellent penetration performance (1% aqueous solution, canvas settling method, penetration force ≤100 seconds), in the leveling process of textile dyeing and printing and in the emulsification and dispersion of pesticide formulations, it can achieve more uniform and stable treatment effects with lower addition amounts, helping downstream customers reduce costs and increase efficiency. Technical Parameter Comparison The following is a comparison of core parameters for different EO number dodecylamine polyoxyethylene ether products from Guoli Chemical (some data for low EO products are temporarily unavailable and supplemented with general characteristics): Parameter AC-1215 (15EO) AC-1210 (10EO) AC-1205 (5EO) AC-1202 (2EO) Appearance (25°C) Colorless to light yellow transparent liquid Colorless to slightly yellow liquid Colorless to light yellow transparent liquid Colorless to slightly yellow transparent liquid HLB Value Approximately 15.6 Approximately 12-13 Approximately 10-11 Approximately 6-7 Cloud Point (1% Aqueous Solution) >100°C (No cloud point) Approximately 80-90°C Approximately 40-50°C Insoluble in water (turbid) Water Solubility Easily soluble in water, transparent solution Soluble in water, good dispersion Dispersible in water Oil soluble, insoluble in water Amine Value (mg KOH/g) 55~65 Parameter temporarily unavailable Parameter temporarily unavailable Parameter temporarily unavailable Surce Tension (1%, 25°C) ~31 mN/m Parameter temporarily unavailable Parameter temporarily unavailable Parameter temporarily unavailable Core Characteristics High hydrophilicity, nonionic/cationic dual nature, acid resistance Moderate hydrophilicity, emulsification and detergency Low hydrophilicity, emulsification and dispersion, defoaming Lipophilic, W/O emulsification, antistatic Application Suggestions Based on the above advantages, choosing AC-1215 in the following scenarios will yield significant benefits: Acidic cleaning/pickling systems: Utilizing its property of converting to a cation under acidic conditions, it acts as a solubilizing auxiliary and metal corrosion inhibition component, with effects r superior to ordinary nonionic surctants. High-concentration liquid detergents and industrial cleaning: Its high water solubility and high HLB value make it an effective solubilizer, helping to dissolve poorly soluble nonionic actives or fragrances into the system without forming a gel phase. Pesticide emulsion in water (EW) and microemulsion (ME): The extremely high HLB value implies strong O/W emulsification ability, effectively inhibiting droplet coalescence, ensuring no oil separation or sedimentation during long-term storage. Textile high-temperature high-pressure leveling: The no-cloud-point characteristic ensures that during high-temperature (130°C) and high-pressure dyeing processes, the surctant does not precipitate to form tarry spots, ensuring leveling effect and bric cleanliness. Precautions Compatibility: Although it has strong compatibility, in strong anionic systems, attention should be paid to its potential protonation to form cations. It is recommended to conduct small-scale compounding tests first to avoid precipitation. Safe Handling: Although AC-1215 has low acute toxicity, it is classified as GHS Category 2 skin and eye irritant (H315/H319). Please be sure to wear nitrile gloves and chemical safety goggles during handling. Storage Conditions: This product is slightly hygroscopic. After opening, please seal promptly and store in a dry, cool place at 5-35°C. The shelf life is 12 months.

Question 8

How to use dodecyl polyoxyethylene ether AC-1215? What is the recommended dosage?

Accepted Answer

Dodecyl polyoxyethylene ether AC-1215 (Lauryl amine polyoxyethylene ether) is a multifunctional nonionic surctant that can exhibit cationic characteristics in acidic media. When used, it is generally directly added to the formulation system in liquid form and stirred until dissolved; its recommended dosage varies depending on the application field, typically ranging from 0.5% to 10%. Detailed Description Dodecyl polyoxyethylene ether AC-1215 (CAS No.: 26635-75-6) is a colorless to light yellow transparent liquid at room temperature, easily soluble in water and various organic solvents. Its usage method is very simple: in industrial formulation production, it is usually directly added as an auxiliary component to the mixing system and stirred evenly to function. When formulating textile printing and dyeing auxiliaries, it can be added to the working solution for circulation; in pesticide formulations, it is often used as an emulsifying dispersant during the mixing process of oil and water phases; in daily chemical products, it is generally added during the heating and stirring stage of the aqueous phase to synergize with other surctants. The core characteristic of this product lies in its molecular structure containing both tertiary amine groups and polyoxyethylene ether segments (EO number approximately 15). This not only provides excellent emulsifying, wetting, and dispersing capabilities of nonionic surctants, but also transforms into a cationic surctant in acidic media due to the protonation of amine groups, thus imparting additional functions such as antistatic properties, softening, and conditioning. With an HLB value of approximately 15.6 and a cloud point >100°C, it maintains stable performance under high temperature and a wide pH range. As a mature product of Guoli Chemical, AC-1215 has been widely used in industries such as textile printing and dyeing, pesticide formulations, industrial cleaning, daily chemical care, and metalworking fluids, with advantages including hard water resistance, acid and alkali resistance, and flexible compatibility.

Actual optimal dosage should be determined through small-scale and pilot experiments. In acidic formulations, the cationic characteristics of AC-1215 will be enhanced, and the dosage can be appropriately reduced. Precautions Safety Protection: AC-1215 causes skin irritation and serious eye irritation (GHS classification category 2). During operation, nitrile rubber or chloroprene rubber protective gloves, chemical safety goggles, and protective clothing must be worn to avoid direct contact. Operating Environment: Operate in a well-ventilated area, avoid inhaling steam or mist. If a large amount of aerosol is formed, wear a combined organic vapor/particulate respirator. Emergency Treatment: If skin contact occurs, immediately rinse with plenty of soap and water for at least 15 minutes. If enters eyes, hold eyelids open and rinse with plenty of water for at least 15 minutes, and seek medical attention immediately. Do not orally administer anything to unconscious persons. Storage Requirements: Store in a cool (5~35°C), dry, well-ventilated warehouse, keep container tightly sealed, away from strong oxidizers and strong acids. Shelf life is 12 months. Environmental Tips: Toxic to aquatic organisms (Fish 96h LC50: 1–10 mg/L), although readily biodegradable, leakage into water bodies or soil must be strictly prevented.

Question 9

In which industries and processes is Dodecylamine Polyoxyethylene Ether AC-1215 mainly used?

Accepted Answer

Dodecylamine Polyoxyethylene Ether AC-1215 is widely used in six major industries: textile printing and dyeing, agricultural chemicals, industrial cleaning, daily chemical care, metalworking fluids, and acidic systems Detailed Description Dodecylamine Polyoxyethylene Ether AC-1215 (CAS No.: 26635-75-6) is a nonionic surctant synthesized through the addition polymerization of tty amines with ethylene oxide. Its molecular structure contains both amine functional groups and polyoxyethylene ether segments, endowing the product with unique intercial activity and multifunctional properties. In acidic media, protonation of the amine groups makes the product behave as a cationic surctant. This "nonionic-cationic dual characteristic" greatly expands its application range, allowing it to maintain excellent performance over a wide pH range. The product possesses five core properties: excellent emulsifying ability (effectively reducing oil/water intercial tension to form stable emulsions), outstanding wetting and penetration properties (promoting liquid spreading on solid surces), superior dispersing performance (preventing flocculation and sedimentation of solid particles), resistance to hard water, acids and alkalis, and blending flexibility with both nonionic and cationic characteristics. These features make it an indispensable key auxiliary agent in many industrial formulations. From a physicochemical perspective, AC-1215 appears as a colorless to light yellow transparent liquid, with a pH of 8-10 for a 1% aqueous solution, a density of approximately 0.95-1.05 g/cm³, a flash point >100°C, it is soluble in water and dispersible in various organic solvents, and has a shelf life of 12 months under recommended storage conditions (5-35°C, cool and dry place). Detailed Explanation of Six Application Industries and Processes 1. Textile Printing and Dyeing — Leveling Agent and Antistatic Agent During the dyeing process of various fibers (cotton, polyester, acrylic, nylon, etc.), AC-1215 acts as an efficient leveling agent. Through its excellent penetration and dispersion capabilities, it ensures uniform adsorption of dye molecules on the fiber surce, effectively reducing color differences and uneven dyeing, thereby improving the first-pass yield of dyeing. Additionally, its antistatic function reduces the surce resistance of fibers, preventing issues such as fiber entanglement, fly waste adhesion, and yarn breakage during processing due to static electricity accumulation. This is particularly suitable for high-speed spinning and weaving processes of synthetic fibers. 2. Agricultural Chemicals — Emulsifying Dispersant for Pesticide Emulsifiable Concentrates and Emulsions in Water In pesticide emulsifiable concentrate (EC) and emulsion in water (EW) formulations, AC-1215 serves as an emulsifying dispersant that effectively reduces the intercial tension between the oil phase and water phase, ensuring that the pesticide active ingredient, solvent, and additives form a uniform and stable emulsion. The diluted liquid remains evenly distributed over a long period without layering or precipitation, thereby ensuring uniform deposition of active ingredients during field application and improving pesticide utilization. Its resistance to hard water is particularly important in agricultural areas where hard water is used for dilution. 3. Industrial Cleaning — Solubilizer and Wetting Agent for Hard Surce Cleaning In industrial hard surce cleaning formulations, AC-1215 acts as an efficient solubilizer and wetting agent. It can rapidly penetrate the interce between the dirt layer and the substrate, reduce dirt adhesion, and enhance cleaning efficiency. Suitable for applications such as cleaning metal parts, glass, ceramic surces, and food processing equipment. Its resistance to acids and alkalis allows compatibility with acidic cleaning formulations (e.g., rust removal, descaling) and alkaline cleaning formulations (e.g., degreasing, degreasing), providing high flexibility in formulation design. 4. Daily Chemical Care — Antistatic Conditioning Agent Used in daily chemical products such as shampoos, conditioners, and body washes, AC-1215 provides excellent antistatic and conditioning functions. Its amine functional groups have good adsorption affinity for hair keratin, forming a smooth protective film on the hair shaft surce, improving wet and dry combability and touch, reducing frizz, flyaways, and static electricity. It is especially suitable for damaged hair repair formulations and anti-static care products in winter. 5. Metalworking Fluids — Emulsifying Antirust Agent In metalworking fluid formulations such as cutting fluids, grinding fluids, and rolling fluids, AC-1215 provides dual functions of emulsification and rust prevention. On one hand, it uniformly emulsifies base oils and functional additives into a stable working fluid, ensuring lubrication and cooling performance during processing; on the other hand, its amine groups form a dense adsorption film on metal surces, effectively inhibiting corrosion of ferrous metals such as cast iron and carbon steel by water molecules and oxygen. This is particularly critical for in-process rust prevention of machined parts. 6. Solubilizing Auxiliary Agent for Acidic Systems In industrial applications such as acidic cleaning, pickling, and acidic medium treatment, AC-1215 utilizes its cationic characteristics upon amine protonation to act as a solubilizing auxiliary agent. It improves the compatibility and solubility of various components in the system, preventing the active ingredients from layering or precipitating out. It is particularly suitable for industrial applications requiring uniform stability of formulations under acidic conditions.
