Question 1

Is dodecylamine polyoxyethylene ether AC-1202 harmful to human body? Does it have any impact on the environment?

Accepted Answer

Dodecylamine polyoxyethylene ether AC-1202 is irritating and has certain potential hazards to humans, and it also has adverse effects on the aquatic environment, requiring strict management. Impact on Human Health According to the product safety data provided by Guoli Chemical, dodecylamine polyoxyethylene ether AC-1202 (lauryl alcohol polyoxyethylene (2) ether) is a chemical with low to moderate irritation. Direct skin contact may cause redness, pain, or persistent irritation; eye contact can result in severe discomfort, requiring immediate flushing with plenty of water. Inhalation of its vapor or mist may irritate the respiratory tract, and accidental ingestion may cause gastrointestinal discomfort. The product manual explicitly requires wearing chemical safety goggles, impermeable gloves, and protective clothing during handling, and thoroughly washing exposed skin after handling, indicating a clear occupational exposure risk. However, the database does not contain specific acute toxicity values (e.g., LD50) for this product. Based on the general characteristics of similar tty alcohol polyoxyethylene ethers, their acute oral toxicity is usually low, but at high concentrations, they may still cause mucosal irritation. Due to the presence of an amine group, it exhibits cationic properties in acidic media, which may enhance adsorption and irritation to skin and mucous membranes. Therefore, although the risk under routine use is controllable, strict chemical safety precautions are required, and eating, drinking, or smoking in the workplace is prohibited. Impact on the Environment This product poses potential hazards to the aquatic environment. According to the safety guidelines from Guoli Chemical, spill handling explicitly requires "preventing entry into drains, waterways, or soil" and recommends high-temperature incineration for waste disposal, which must be handled by qualified waste treatment units, and discharge into natural water bodies is strictly prohibited. This indicates that the product has certain acute or chronic toxicity to aquatic organisms and may not degrade rapidly in the natural environment or may still cause adverse effects after degradation. As a nonionic surctant widely used in pesticide emulsification, industrial cleaning, and metal processing, dodecylamine polyoxyethylene ether AC-1202, if present in excessive concentrations in natural water bodies, can reduce surce tension, affect oxygen exchange, and be toxic to fish gills and plankton. Therefore, emissions must be strictly controlled during use, and waste liquid collection and compliant disposal must be implemented to avoid environmental pollution. The database does not contain specific data on biodegradation and ecotoxicity for this product. Key Safety Operating Parameters Parameter Item Indicator Characteristics (from Guoli Chemical Database) Appearance Colorless to slightly yellow transparent liquid with good fluidity pH Value (1% aqueous solution) 6.0~8.0 Flash Point ＞100°C (Combustible liquid but not easily flammable) Water Solubility Insoluble in water, soluble in organic solvents Heavy Metal Content ≤10 mg/kg Arsenic Content ≤2 mg/kg Chemical Stability Stable at room temperature, avoid contact with strong oxidizers Precautions Local ventilation or general ventilation must be provided during operation to avoid vapor accumulation. Skin and eye protection are mandatory; ensure proper wearing of nitrile rubber gloves and safety goggles. Although it is a combustible liquid, never use a direct water stream for firefighting; use dry powder, carbon dioxide, or alcohol-resistant foam. Waste liquid and contaminated containers must be disposed of as hazardous waste by professional agencies; do not mix with domestic waste or discharge into drains. No acute toxicity data (LD50/LC50) or specific ecological risk profile is available in the database; it is recommended to obtain a safety assessment report before large-scale use.

Question 4

Does dodecylamine polyoxyethylene ether AC-1202 meet environmental requirements? Can a test report be provided?

Accepted Answer

There is no environmental certification qualification or test report for AC-1202 in the database. However, based on product characteristics and industry standards, if compliant use is required, it is recommended to apply to Guoli Chemical Sales Department for batch-specific COA/ROHS/REACH and other special test reports. Detailed Explanation Dodecylamine polyoxyethylene ether AC-1202 (Laureth-2) is a nonionic surctant. From the molecular structure and general industry attributes, this type of short-chain tty alcohol polyoxyethylene ether usually has good biodegradability. However, strict environmental compliance (such as EU REACH regulations, ROHS 2.0, ZDHC detoxification action, etc.) needs to be determined by combining test data on heavy metal content (such as lead, mercury, cadmium, etc.) and specific restricted substances (such as APEO, NPEO and other alkylphenol polyoxyethylene ethers). From the physicochemical indicators provided by the database, AC-1202 has a heavy metal content of ≤10 ppm and an arsenic content of ≤2 ppm, both at low levels, and contains no free phosphoric acid or amine impurities. These data indicate strict purity control, but are not sufficient to directly equate to complete environmental certification. As a professional industrial auxiliary, its environmental compliance ultimately depends on the industry regulations of the end application. Technical Parameters Parameter ItemValue/DescriptionEnvironmental Relevance Explanation Heavy Metal Content≤10 ppmLower than general industrial discharge standards, relatively environmentally friendly Arsenic Content≤2 ppmComplies with conventional agrochemical/industrial cleaning industry safety standards Active Substance Content≥99%High purity means fewer by-products, reducing waste disposal pressure Chemical StabilityStable at room temperature, avoid strong oxidizersUnlikely to produce harmful decomposition products in natural environment Waste Disposal StandardHigh-temperature incineration as hazardous wasteRequires exhaust gas purification device to prevent formation of dioxins, etc. Test ReportNot availableNeed to contact Guoli Chemical for batch-specific issuance Application Suggestions 1. Export and Strict Market Audits: If used for export to the EU, USA, or Japan/Korea as textile auxiliaries, cleaning agents, etc., it is usually required to provide REACH SVHC testing, ROHS six items, and halogen testing with the shipment. It is recommended to call Guoli Chemical Sales Department in advance to apply for a Declaration of Conformity (DoC) for the specific batch number. 2. Textile Industry Compliance: If used as a textile auxiliary, note that end buyers typically require OEKO-TEX ECO PASSPORT certification or ZDHC MRSL Level 3 compliance proof. AC-1202 itself does not contain APEO in its structure, which is a major advantage, but laboratory testing is still needed to confirm no cross-contamination. 3. Wastewater Treatment Suggestions: AC-1202 is a low-foaming surctant, easy to rinse, but wastewater treatment cilities should be equipped at the end of the process to prevent direct discharge. It is recommended to use activated sludge method or advanced oxidation process for treatment to meet discharge standards. Precautions The indicators listed in the database are Guoli Chemical's ctory internal control standards and cannot directly replace environmental test reports issued by third-party institutions. Test reports usually require a certain handling fee, and data may fluctuate with different batch numbers, which is normal. This product is flammable and waste disposal must follow hazardous waste procedures; do not arbitrarily dump to cause water pollution.

Question 5

What are the advantages of Dodecyl Polyoxyethylene Ether AC-1202 compared to other similar products?

Accepted Answer

The core advantage of Dodecyl Polyoxyethylene Ether AC-1202 lies in its extremely low degree of ethoxylation (EO=2), giving it the strongest lipophilicity, lowest foam, stest penetration rate, and unique oil solubility among products in the same series, making it irreplaceable in fields such as degreasing, water-in-oil emulsification, and acidic cleaning. Detailed Description The biggest difference between Guoli Chemical's Dodecyl Polyoxyethylene Ether AC-1202 (also known as AEO-2 or Polyoxyethylene (2) Dodecyl Ether) and similar products (such as AC-1205, AC-1210, AC-1215) is its extremely low degree of ethoxylation. This molecular structure determines that its HLB value (Hydrophilic-Lipophilic Balance) is only about 6, much lower than other high-EO number products. Therefore, AC-1202 has strong hydrophobic and lipophilic characteristics, insoluble in water but highly soluble in organic solvents and oil phases, making it especially outstanding in formulating water-in-oil (W/O) emulsions and oil-based cleaning agents. Compared to high-ethoxylated similar products, AC-1202 functionally focuses more on "strong penetration and rapid degreasing." Due to its shorter polyoxyethylene chain and smaller molecular size, it can quickly penetrate into tiny gaps of oil stains and substrates, achieving high efficiency in leather degreasing, heavy oil industrial cleaning, and metal degreasing. In addition, it is a typical low-foaming surctant, which can significantly reduce downtime or overflow caused by foam in industrial cleaning lines and circulating water systems that require rapid defoaming or foam suppression. Although both are tty amine polyoxyethylene ethers, AC-1202 and products like AC-1860 each have their strengths. AC-1860 is a solid macromolecule formed by adding 60 EO to octadecylamine, specializing in high-temperature leveling and antistatic properties; while AC-1202 exhibits unique cationic characteristics under acidic conditions, combining bactericidal, corrosion inhibition, and antistatic functions. This dual nonionic and cationic nature imparted by the low EO number enables it to deliver composite effects in formulations such as acid pickling corrosion inhibitors and textile antistatic finishes that high-EO number products cannot replace.

Question 8

How to use dodecylamine polyoxyethylene ether AC-1202? What is the recommended addition amount?

Accepted Answer

The specific usage of dodecylamine polyoxyethylene ether AC-1202 varies significantly depending on the application field. The recommended addition amount should be determined through experiments based on the formulation system and process requirements. The product database currently does not contain standard addition amount data for each application scenario. The following provides general industry usage guidelines for reference. Detailed Description Dodecylamine polyoxyethylene ether AC-1202 (also known as lauryl alcohol polyoxyethylene (2) ether, AEO-2) is a nonionic surctant with an HLB value of 6, insoluble in water but soluble in organic solvents. Its molecular structure contains 2 ethoxy (EO) units, making it strongly lipophilic. Therefore, in pretreatment formulations, it typically needs to be compounded with high-HLB emulsifiers to achieve ideal emulsification and dispersion effects. The product can exhibit cationic properties in acidic media, possessing dual functions of both nonionic and cationic surctants. Before use, fully understand the phase behavior and target performance of the formulation. Due to its strong lipophilicity, when preparing water-based systems, first thoroughly mix AC-1202 with the oil phase or solvent phase, then slowly add the water phase while stirring. If necessary, auxiliary heating (recommended not exceeding 40°C) can be used to reduce material viscosity and improve mixing efficiency. This product is a low-foaming type, especially suitable for industrial applications sensitive to foam, such as circulating spray cleaning and metalworking fluid systems. In industrial formulations, this product is often used as an auxiliary emulsifier or co-surctant. When compounded with high-HLB nonionic surctants (such as AEO-9, TX-10, etc.) or anionic surctants, it can significantly improve the emulsion stability and penetration of the formulation. It is recommended to conduct small-scale compounding experiments before formal production to determine the optimal addition ratio and process conditions.
