Question 1

Is MOA-3 (AEO-3) harmful to humans? Does it have an impact on the environment?

Accepted Answer

MOA-3 (AEO-3) is irritating to humans, causing significant discomfort to the skin and eyes; it also poses long-term hazards to the aquatic environment and is a chemical that requires careful handling. Detailed Explanation MOA-3 (AEO-3) is a tty alcohol polyoxyethylene (3) ether nonionic surctant. According to the GHS classification system for chemicals, its hazard identification is GHS07 (exclamation mark), with the signal word "Warning". This indicates that the product is a chemical with moderate hazards. Under normal industrial use conditions, risks can be effectively controlled through standard protective measures, but its inherent health and environmental hazard characteristics cannot be ignored. From a toxicological perspective, the main health hazard routes for MOA-3 are skin contact and eye contact, classified as Skin irritation category 2 and Eye irritation category 2. This means direct contact may cause skin redness, itching, or discomfort, while splashing into the eyes can cause severe irritation, pain, and congestion. It should be specifically noted that this product is not a highly toxic, carcinogenic, or mutagenic substance. When used under standard operating conditions in industrial formulations (e.g., detergents, personal care products), its direct hazard to humans is significantly reduced after reasonable dilution. From an ecotoxicological perspective, MOA-3 is classified as Chronic aquatic hazard category 3 (H412), meaning that this substance is harmful to aquatic organisms (e.g., fish, algae, aquatic invertebrates) and may persist in natural water bodies for a long time, causing continuous adverse effects. As a surctant, its molecular structure can disrupt the cell membranes of aquatic organisms, interfere with water surce tension, and affect oxygen exchange. Therefore, it is strictly prohibited to discharge untreated wastewater containing this product directly into rivers, lakes, or oceans. Technical Parameters Hazard CategoryHazard CodeHazard DescriptionPictogram Skin irritation (Category 2)H315Causes skin irritationGHS07 Eye irritation (Category 2)H319Causes serious eye irritation Chronic aquatic hazard (Category 3)H412Harmful to aquatic life with long lasting effects Application Recommendations When using MOA-3 in industrial formulation and processing scenarios, safe operating procedures must be strictly followed: operators must wear corrosion-resistant gloves (e.g., nitrile rubber gloves), chemical safety goggles, and protective clothing throughout the operation, and the work area must maintain good ventilation. If MOA-3 is used in personal care products or household detergent formulations (e.g., shampoos, laundry liquids), the surctant concentration in the finished product is significantly diluted and is safe for human use under normal conditions. However, it is recommended that formulation engineers ensure the skin irritation of the final product complies with relevant national standards (e.g., Technical Specifications for Cosmetic Safety). For wastewater treatment, industrial wastewater containing MOA-3 should be treated by the enterprise's own wastewater treatment station or the centralized treatment cilities of the industrial park to meet discharge standards before being released. Surctants can be effectively removed through microbial degradation in activated sludge processes. It is recommended not to directly discharge high-concentration products or untreated rinsing water into municipal pipelines or natural water bodies. Precautions Emergency treatment: In case of skin contact, immediately rinse with plenty of water and soap for at least 15 minutes; in case of eye contact, rinse thoroughly with flowing clean water for at least 15 minutes and seek medical attention immediately; do not induce vomiting if ingested, immediately bring the product container to a doctor. Storage requirements: Recommended storage temperature is 5°C to 35°C, keep away from heat sources and strong oxidizers, keep the container tightly closed, and the storage area should be equipped with spill collection cilities (e.g., trays or berms). Biodegradability: MOA-3, as a tty alcohol polyoxyethylene ether surctant, has certain biodegradability. However, its short-chain structure containing 3 EO units results in a relatively slower degradation rate and stronger environmental persistence compared to similar products with higher EO numbers. Therefore, special caution is required for discharge into water bodies. Compliant disposal: Waste products and contaminated containers must be managed as hazardous waste and disposed of by qualified professional agencies; it is strictly forbidden to discard arbitrarily or discharge into the environment.

Question 2

What to do if problems occur during the use of MOA-3 (AEO-3)? How to obtain technical support?

Accepted Answer

When encountering problems with MOA-3 (AEO-3), start with troubleshooting common symptoms, and contact Hai'an County Guoli Chemical Co., Ltd. immediately for professional technical support if necessary. Common Usage Issues and Troubleshooting Suggestions As a nonionic surctant, MOA-3 (AEO-3) may present the following typical problems during use: 1. Poor emulsification effect: First, check whether the HLB value of the formulation matches. MOA-3 is a tty alcohol polyoxyethylene ether with a low degree of EO polymerization, which is relatively lipophilic and suitable for preparing W/O (water-in-oil) emulsions. If the target system is O/W type, it may be necessary to combine with higher EO number emulsifiers. At the same time, confirm whether the oil phase type and oil-water ratio are within a reasonable range, and whether the homogenization speed and time are sufficient. 2. Turbidity or stratification of the product: The normal appearance of MOA-3 is a colorless to slightly yellow transparent liquid. If turbidity occurs, first check whether the storage temperature is below 5°C — low temperature may cause the product to solidify or precipitate. It can be used after warming up and stirring evenly in an environment of 15°C–35°C. If it remains unclear after warming, the product may have absorbed moisture or been contaminated with impurities. Check the container seal. 3. Gel formation or precipitation in the formulation: Nonionic surctants may exhibit "salting out" in high-concentration electrolyte or strong acid/base systems. Although MOA-3 has good chemical stability (resistant to acids, alkalis, and hard water), compatibility should still be verified through pre-tests under extreme conditions. It is recommended to pre-mix MOA-3 with other components and dilute gradually to avoid adding a large amount at once. 4. Abnormal foaming behavior: MOA-3 itself is a low-foaming nonionic surctant. If excessive foam occurs, it may be due to a synergistic effect with other anionic surctants. If there is no foam at all, check whether the active content meets the specification or whether the product has expired (recommended shelf life is one year under storage conditions). Emergency Handling for Safety Issues In case of skin contact, rinse immediately with plenty of water and soap for at least 15 minutes. If irritation persists, seek medical attention. For eye contact, hold eyelids open and rinse with flowing water for at least 15 minutes, then seek immediate medical attention. In case of leakage, cover and collect with inert materials such as sand or vermiculite, and avoid discharge into water bodies. For detailed emergency measures, refer to the Safety Data Sheet (SDS). How to Obtain Technical Support If the above troubleshooting cannot resolve the problem, or if complex situations such as formulation development, process optimization, or customization needs arise, it is recommended to directly contact the technical team of Hai'an County Guoli Chemical Co., Ltd. Although the official technical service hotline and email are not detailed in public data, you can obtain support through the following channels: Official website inquiry: Visit the Guoli Chemical official website, submit technical questions through online customer service or a message system, along with product batch number, usage conditions, and problem description. Sales manager contact: If purchased through a distributor or directly, contact your dedicated sales manager, who will coordinate technical personnel for one-on-one remote or on-site service.

Detailed Description MOA-3 (AEO-3) is a tty alcohol polyoxyethylene ether with a degree of polymerization of 3, belonging to the low-EO number nonionic surctants. Compared with similar products of higher EO numbers (such as AEO-7, AEO-9), MOA-3 has a lower HLB value (approximately 8-9) and stronger lipophilicity, which gives it an irreplaceable emulsifying advantage in water-in-oil (W/O) emulsion systems. In contrast, AEO-7/AEO-9 and other products have higher HLB values (12-14), making them more suitable for O/W emulsification systems, with a fundamental difference in application positioning. Among similar low-EO number products (such as AEO-2), the advantage of MOA-3 lies in its more balanced EO distribution, combining oil solubility with a certain degree of water dispersibility. AEO-2 is too lipophilic and has poor water dispersibility; while MOA-3 maintains excellent W/O emulsifying power while offering better formulation compatibility and operational convenience. In addition, MOA-3 is a standard-grade intermediate raw material for synthesizing AES (sodium alcohol ether sulte). Its EO chain length directly determines the foaming, mildness, and viscosity characteristics of the final AES product, making it the industry-recognized optimal choice. In terms of product quality itself, Guoli Chemical's MOA-3 features high purity active content (effective ingredients ≥99%), light color (colorless to slightly yellow transparent), and low residual by-products such as polyethylene glycol, which makes downstream products more stable, formulation design more precise, and dosage more economical, offering overall cost-effectiveness superior to low-purity similar products on the market. Key Differences Between MOA-3 and Similar Products Comparison Dimension MOA-3 (AEO-3) AEO-2 (Same Low EO) AEO-7/AEO-9 (Same High EO) HLB Value Approximately 8-9 Approximately 5-6 Approximately 12-14 Emulsification Type W/O (Water-in-Oil) ⭐ W/O O/W (Oil-in-Water) Water Dispersibility Dispersible Poorly Dispersible Easily Soluble/Transparent AES Raw Material Suitability Optimal Standard ⭐ Low Sulfonation Efficiency Not Applicable Wetting and Penetration Power Excellent Moderate Average Degreasing Ability Strong ⭐ Too Strong, Poor Selectivity Relatively Weak Chemical Stability Resistant to Acid/Alkali/Hard Water Resistant to Acid/Alkali/Hard Water Resistant to Acid/Alkali/Hard Water Active Content ≥99% (Guoli Chemical) Depends on Manucturer Depends on Manucturer Application Suggestions 1. AES Production: MOA-3 is the industry standard raw material for producing AES. After sulfonation, the resulting AES exhibits ideal foaming power, mildness, and thickening properties, making it the core surctant in shampoos, body washes, and cial cleansers. Choosing high-purity MOA-3 can significantly improve the first-grade product ratio of AES. 2. W/O Emulsion Preparation: In formulations requiring water-in-oil emulsification systems (such as certain skin creams, metalworking water-in-oil emulsions), MOA-3 is the preferred emulsifier due to its low HLB value, offering emulsion stability superior to hydrophilic emulsifiers like AEO-7/AEO-9. 3. Textile and Leather Processing: When used as a scouring agent and degreasing agent, MOA-3's strong penetration and excellent oil removal efficiency surpass those of high-EO number products, making it especially suitable for cotton pretreatment and raw hide degreasing processes. 4. Metal Cleaning: Its strong degreasing power and rapid wetting ability make it perform excellently in heavy oil dirt cleaning scenarios. It can be compounded with high-EO number products to achieve optimal cleaning balance. Precautions MOA-3 has limited water dispersibility and is not suitable for direct use in formulations requiring transparent aqueous solutions.

Question 8

How to use MOA-3 (AEO-3)? What is the recommended dosage?

Accepted Answer

The specific method of using MOA-3 (AEO-3) varies depending on the application scenario. It is usually added directly to the oil phase as a W/O emulsifier, wetting agent, or dispersant to participate in the formulation. The Guoli Chemical product database does not provide fixed dosage amounts for various application scenarios; the actual dosage needs to be determined through experiments based on the formulation system and process objectives. Detailed Description 1. Basic Usage Principles MOA-3 is a typical low-polymerization tty alcohol polyoxyethylene ether with an HLB value of approximately 8, strong lipophilicity, easily soluble in oils and organic solvents, and dispersible/diffusible in water (cloud point below 20°C). Therefore, it is generally recommended to first dissolve or disperse MOA-3 in the oil phase before mixing with other aqueous phase components, which allows it to fully exert its W/O emulsifying and wetting effects. If added directly to the aqueous phase, strong stirring is required for uniform dispersion. 2. Operation Methods for Typical Application Scenarios Emulsion Polymerization (as emulsifier): Premix MOA-3 with monomers (such as acrylates, styrene, etc.) evenly, then slowly add to the aqueous phase under stirring for pre-emulsification to form a stable monomer emulsion before initiating polymerization. When used as the primary emulsifier, its dosage can refer to the typical addition range of nonionic emulsifiers. Metal Cleaning/Hard Surce Cleaner: Premix MOA-3 with oil-soluble solvents, builders, etc., to form a clear oil phase, and dilute to working concentration before use. Its low-foam property makes it especially suitable for high-pressure spray cleaning systems. Textile Scouring/Penetrating Agent: When preparing the working solution, first disperse MOA-3 into an emulsion with a small amount of warm water (40-50°C), then add to the main bath and stir evenly. It is recommended to combine with anionic surctants when used as a penetrating agent to enhance effectiveness. Leather Degreasing: Mix directly with organic solvents or water in proportion to form a degreasing solution, and treat the raw hide in a drum to separate natural ts from the skin using its excellent emulsifying ability.

The optimal dosage must be determined through gradient experiments in actual formulations: W/O Emulsion/Cream Emulsification: 2%~8% (based on oil phase weight), as the primary emulsifier, can be combined with a small amount of high HLB emulsifier to adjust the hydrophilic-lipophilic balance. Emulsion Polymerization Emulsifier: 1%~5% (based on total monomer weight), if necessary, compounded with anionic surctants to enhance mechanical stability and control particle size. Industrial Liquid Detergent/Hard Surce Cleaner: 0.5%~5% (based on total formulation weight), utilizing its penetrating and degreasing ability, low-foam property can reduce the amount of defoamer needed. Textile Pretreatment Scouring Agent/Penetrating Agent: 1~3 g/L (working solution concentration), usually works best when combined with anionic surctants and additives. Leather Degreasing Agent: 0.5%~2% (working solution concentration), specific dosage adjusted according to the t content of the raw hide. Metal Parts Cleaning Agent: 3%~10% (formulation concentrate), diluted to appropriate multiples at the site of use. Intermediate for Synthetic AES: As a main raw material, the specific usage amount depends on the subsequent sulfonation/sultion process design and is determined by the process engineer. Precautions Compounding Synergy: MOA-3 has good compatibility with nonionic, anionic, and cationic surctants. In actual formulations, it is often compounded to optimize overall performance (e.g., combined with AES, LAS, or betaine to balance foam and detergency). Temperature Effects: The cloud point of MOA-3 is below 20°C. Turbidity or stratification may occur at lower temperatures, which is a normal physical phenomenon. Stir well before use; product performance is not affected. For transparent water-based product formulations, attention should be paid to the cloud point matching of the system. Safety Protection: Wear chemical safety goggles and chemically resistant gloves (e.g., nitrile rubber gloves) during operation. Ensure the operation area is well-ventilated, and avoid skin and eye contact. See product SDS for specific safety information. Storage Recommendations: Store sealed in a cool, dry place (5°C~35°C), avoid mixing with strong oxidizers. The shelf life for unopened products is one year from the production date. Environmental Note: Causes long-lasting harmful effects to aquatic organisms (H412). Do not discharge undiluted product directly into water bodies or drainage systems. Dispose of waste through qualified professional agencies.

Question 9

In which industries and processes is MOA-3 (AEO-3) mainly used?

Accepted Answer

MOA-3 (AEO-3) is mainly used in six major industries: personal care, industrial cleaning, textile printing and dyeing, leather processing, metal processing, and emulsion polymerization. It is a key raw material for synthesizing AES and performs core functions such as emulsification, wetting, penetration, and dispersion in these fields. Detailed Description MOA-3 (AEO-3) is a C12-14 tty alcohol polyoxyethylene (3) ether, belonging to the class of nonionic surctants. Due to the low EO addition number (3EO) in its molecular structure, the product exhibits excellent water-in-oil (W\/O) emulsifying ability, outstanding wetting and penetrating properties, as well as chemical stability against acids, alkalis, and hard water. These characteristics make it an indispensable functional additive in multiple industrial fields. From the perspective of the industrial chain, the most core use of MOA-3 is as a main raw material for synthesizing sodium alcohol ether sulte (AES). AES is one of the most widely used anionic surctants globally, extensively applied in personal cleansing products such as shampoo, body wash, and hand soap. Therefore, MOA-3 occupies a critical upstream position in the entire surctant industry chain. Additionally, MOA-3 itself can be directly used or modified in end-use formulations, providing mild cleaning, emulsifying, and conditioning functions.

Question 10

What are the physicochemical technical parameters of MOA-3 (AEO-3)?

Accepted Answer

MOA-3 (AEO-3) is a low-polymerization nonionic surctant with an HLB value of approximately 8, exhibiting typical W/O emulsifying properties, easily soluble in oil and dispersible in water. Detailed Description MOA-3 (AEO-3) has the chemical name C12-14 tty alcohol polyoxyethylene (3) ether, which is a nonionic surctant formed by the addition polymerization of C12-14 tty alcohol with about 3 moles of ethylene oxide. The product appears as a colorless to slightly yellow transparent liquid with an active content of over 99% and excellent purity. Due to its low ethylene oxide addition number (n≈3), the lipophilic group dominates the molecular structure, resulting in an HLB value of about 8, making it a lipophilic surctant primarily forming water-in-oil (W/O) emulsions. This product exhibits excellent chemical stability, with resistance to acids, alkalis, and hard water, maintaining stable performance in complex formulation systems. Its low foaming特性 makes it particularly suitable for applications requiring quick defoaming or low-foam processes. The product density is 0.92~0.94 g/cm³, and the flash point is greater than 150°C, lling within a relatively safe operating range, although its flammability should still be noted.
