Product is difficult to take out or inconvenient to use MOA-23 (AEO-23) is a white waxy solid with a melting point of about 40~45°C, solid at room temperature. During operation, it can be preheated and softened in a 35~50°C warm water bath, or the whole barrel can be moved to a warm room for storage (not exceeding 40°C), and then feed after the material softens. Note: This operation is a change in physical state and does not affect the activity and quality of the product. 2. Softening or partial melting during summer storage Softening of the product in the barrel during high temperature seasons is a normal physical phenomenon, not product deterioration. The Guoli Chemical product database clearly states that this condition does not affect the use effect. It is recommended to store the product in a cool, ventilated place, with a recommended storage temperature of 5°C to 40°C, avoiding direct sunlight and continuous high temperature environment. 3. Turbidity or uneven dispersion after dissolution The HLB value of MOA-23 is about 16.5, the cloud point is >100°C (1% aqueous solution), and it is easily soluble in water. If there is difficulty in dissolution or turbidity, the common causes and countermeasures are: Water temperature too low: It is recommended to pre-dissolve in 40~60°C warm water before adding to the system Too st feeding speed: Add slowly and stir thoroughly to avoid forming agglomerates Adding simultaneously with high concentration electrolytes or strong acids/bases: It is recommended to add in stages, first dissolve MOA-23 and then add other auxiliaries 4. Unsatisctory emulsion stability MOA-23, as a nonionic emulsifier with a high HLB value (about 16.5), is specifically designed for O/W (oil-in-water) emulsion systems. If the emulsion shows layering or breaking, you can check from the following aspects: Oil phase type and HLB compatibility: Confirm whether the required HLB value of the emulsified oil phase is within the applicable range of MOA-23 (about 15~18), and if necessary, blend with low HLB value emulsifiers Emulsification process: Whether the homogenization speed and time are sufficient, high shear emulsification equipment is recommended Addition amount: Adjust the dosage according to the solid content and oil phase ratio of the system, usually 3%~10% of the oil phase weight 5. Accidental skin or eye contact MOA-23 is classified under GHS as Skin irritation category 2 (H315) and Serious eye irritation category 2A (H319). In case of contact, immediately handle as follows: Skin contact: Remove contaminated clothing, rinse with plenty of water and soap, seek medical attention if irritation persists Eye contact: Immediately rinse with plenty of water for at least 15 minutes, lifting eyelids frequently. If wearing contact lenses, remove them first. If irritation persists after rinsing, seek medical attention immediately During operation, be sure to wear nitrile rubber gloves and protective goggles/ce shield.

Question 5

What are the advantages of MOA-23 (AEO-23) compared to similar products?

Accepted Answer

The core advantage of MOA-23 (AEO-23) lies in its ultra-long polyoxyethylene chain (n≈23), which endows the product with excellent high-temperature stability, a wide range of applicable HLB values, and extremely fine emulsification and dispersion capabilities. It is a benchmark product among similar nonionic surctants for high-temperature and high-pressure processes and high-stability emulsion systems. Detailed comparison description Compared to common low-molar-number tty alcohol polyoxyethylene ethers (such as AEO-3, AEO-7, or AEO-9), MOA-23 has the most significant differentiated competitive advantage—its large hydrophilic group (23 ethylene oxide units) brings a HLB value of up to 16.5 and a cloud point of over 100°C in aqueous solution. This means that when ordinary nonionic surctants become ineffective due to dehydration and precipitation at high temperatures, MOA-23 can still maintain a clear dissolved state and efficient surce activity. This makes it irreplaceable in demanding scenarios such as high-temperature and high-pressure leveling in textiles and industrial high-temperature cleaning. In terms of emulsifying capacity, MOA-23 is r superior to conventional AEO products with low EO addition levels. It forms emulsions with finer particle sizes and more lasting stability, making it particularly suitable for emulsion polymerization in fine chemicals and O/W cream systems in cosmetics. Meanwhile, data from the Guoli Chemical database shows that the product has an active matter content of ≥99% and free alcohol content controlled at ≤1.0%. This means that in actual formulations, you can achieve higher emulsification efficiency with less addition, and the final product has lower odor and irritation, which is crucial for personal care and high-end cleaning products. In terms of compatibility and safety/environmental protection, MOA-23 also performs outstandingly. It has strong tolerance to acids, alkalis, and hard water ions, and is well compatible with anionic, cationic, and amphoteric surctants, offering extremely high formulation flexibility. Toxicological data shows an oral LD50 in rats of >2000 mg/kg, indicating low toxicity, and it also has good biodegradability (WGK 1). It fully meets the current mainstream trend of green and environmentally friendly formulations and has greater social compliance advantages than some traditional hard-to-degrade nonionic surctants.

Ultra-stable emulsion requirements: In styrene-acrylic/acrylate emulsion polymerization, ink removal systems, and pesticide microemulsions, leveraging its strong dispersion and emulsion stabilization characteristics to obtain excellent batch products. High-end O/W formulations: Used as the main emulsifier and solubilizer in sunscreens, cleansing creams, and makeup removers, providing a gentle skin feel and effectively solubilizing highly hydrophobic ingredients like fragrances and essential oils. Low-temperature solid formulations: Utilizing its ≥99% active matter content and waxy solid form to conveniently produce high-quality solid toilet cleaning blocks, laundry pod outer film formulations, etc. Precautions Note that MOA-23 is a highly waxy solid. In winter or cold storage environments, it needs to be kept warm or pre-melted before feeding. Recommended storage temperature is 5°C to 40°C. Melting at 40~45°C is a normal physical phenomenon and does not affect quality. Additionally, its surce tension reduction rate is slightly slower than that of low-molar AEO. If rapid spreading and instant penetration are required, it is recommended to blend with other low-HLB surctants or penetrants.

Question 8

How to use MOA-23 (AEO-23)? What is the recommended dosage?

Accepted Answer

Usage Method and Recommended Dosage of MOA-23 (AEO-23) Detailed Explanation MOA-23 (AEO-23) is a nonionic tty alcohol polyoxyethylene ether with a high degree of polymerization. At room temperature, it appears as a white to slightly yellow waxy solid (melting point approximately 40~45°C). Before use, it must be melted by heating or dissolved in hot water, then mixed with other formulation components. With an HLB value of about 16.5, strong hydrophilicity, easy solubility in water, and a cloud point above 100°C, it is particularly suitable for high-temperature processes or formulations requiring high hydrophilic emulsifying power. During use, it is recommended to first add MOA-23 alone into the kettle, stir and dissolve it with hot water at about 60~70°C to form a transparent and uniform liquid, then add other surctants or auxiliaries. For liquid formulations such as laundry detergents and cleaning agents, it can be used synergistically with other anionic or amphoteric surctants, typically added as an auxiliary emulsifier or solubilizer. In O/W cream systems for cosmetics, it should be added during the heating phase of the water phase to utilize its excellent emulsifying ability to form a stable and fine emulsion. Since the product database does not provide absolute standard dosage formulations for various application fields, the following recommended dosages are based on product characteristics of Guoli Chemical and general industry practical experience. The optimal dosage should be determined through small-scale experiments during actual production. Recommended Dosage Reference (Industry General Recommendations, Not Absolute Standards) Application Field Recommended Dosage (% of Total Formulation Weight) Usage Description Textile Dyeing Leveling Agent/Dispersant 0.5% ~ 2.0% Prevent dye aggregation, improve dyeing uniformity Industrial Hard Surce Cleaner / Metal Degreaser 2.0% ~ 8.0% Combine with alkali agents and builders to exert strong emulsifying and degreasing effects Household Detergents (Laundry Liquid/Laundry Powder) 1.0% ~ 5.0% Enhance detergency and control foam; note that it is a low-foam surctant Cosmetics and Personal Care O/W Emulsifier 0.5% ~ 3.0% As primary or auxiliary emulsifier for creams and lotions Flavor/Essential Oil Solubilization 3 ~ 5 times the oil phase amount Utilize high HLB value to solubilize hydrophobic components Leather Degreasing Agent 1.0% ~ 4.0% Effectively remove natural ts from raw hides Paper Deinking Agent 0.1% ~ 0.5% (based on oven-dried waste paper weight) Separate and remove ink, improve pulp whiteness Emulsion Polymerization Emulsifier 1.5% ~ 3.0% (based on monomer weight) Provide stable monomer emulsification to obtain uniform particle size emulsion ※ The above dosages are common recommended ranges for similar domestic high-HLB AEO-type products, not fixed parameters from Guoli Chemical's product database. Final dosage must be verified through laboratory small-scale experiments. Application Suggestions MOA-23 exhibits excellent resistance to acids, alkalis, and hard water, allowing safe use in complex water conditions and harsh chemical environments. Its low-foam property is especially suitable for surce treatment processes requiring low or no foam (e.g., metal cleaning, paper deinking). Since the product has an active content ≥99%, actual usage efficiency is high, and the dosage can be reduced accordingly compared to low-active-content products. It is recommended to start from the lower end of the recommended range during initial formulation trials and gradually optimize to achieve the best effect. In terms of compatibility, MOA-23, as a nonionic surctant, has good compatibility with anionic (e.g., LAS, AES), cationic, and amphoteric surctants. When compounded, it can produce significant synergistic effects and is commonly used to form composite detergent and emulsifier systems. Precautions Dissolution Operation: This product is a solid wax block. It must be melted or dissolved in hot water before use. Do not add it directly to cold water and let it sit, as dissolution will be extremely slow. It is recommended to equip containers and pipes with insulation jackets to prevent solidification. Personal Protection: During operation, wear nitrile rubber gloves and protective goggles/ce shield to avoid product dust or solution splashing into eyes (may cause serious eye irritation, H319) and prolonged skin contact (may cause skin irritation, H315). Storage Conditions: Store sealed in a cool, dry, and well-ventilated place. Recommended storage temperature: 5°C to 40°C. Softening of the waxy solid during high-temperature seasons is a normal physical phenomenon and does not affect product quality. Formulation Taboos: Avoid direct mixing with strong oxidizing agents. When compounding with strong acid systems, pre-verify compatibility and stability.

Question 10

What are the physical and chemical technical parameters of MOA-23 (AEO-23)?

Accepted Answer

MOA-23 (AEO-23) is a nonionic surctant with a high HLB value (about 16.5), typically appearing as a white to slightly yellow waxy solid, easily soluble in water, with a cloud point above 100°C. Detailed Description MOA-23, chemical name C12-14 tty alcohol polyoxyethylene (23) ether (CAS No.: 68439-50-9), is a high-adduct nonionic surctant polymerized from natural tty alcohols and ethylene oxide. Its molecular weight is about 1200, and it appears as a white to slightly yellow waxy solid with a melting point between 40~45°C. The product has an active matter content of no less than 99%, demonstrating extremely high purity and usage efficiency. Due to its long polyoxyethylene chain (n≈23), this product exhibits excellent water solubility, high cloud point (>100°C), and outstanding stability against acids, alkalis, and hard water. Its surce activity is mild, with an intercial tension of about 32 mN/m and a critical micelle concentration (CMC) of about 0.04 g/L, forming stable and fine emulsions with low foam, making it easy to rinse. The pH value (1% aqueous solution) is weakly acidic to neutral (5.0~7.0), with slight irritation to skin and eyes (H315/H319). With its HLB value of about 16.5, MOA-23 performs excellently in O/W emulsification, dispersion, and solubilization. Additionally, it has good biodegradability and batch quality stability, meeting the stringent requirements of modern environmental protection and industrial production for fine chemicals. Its flash point is above 200°C, non-flammable at room temperature, but ventilation and protection are still needed during high-temperature operation or storage.

Application Suggestions Due to its high HLB value and high cloud point, MOA-23 is particularly suitable for high-temperature operation systems and the construction of O/W (oil-in-water) emulsion systems. Recommended application scenarios and dosage references are as follows: Textile Dyeing and Finishing: Used as a high-temperature leveling agent and dispersant. The recommended dosage is 1~3 g/L (based on dye bath volume), which can effectively prevent dye aggregation and improve color stness. Industrial Cleaning: As a core component of heavy-duty metal degreasers, recommended formulation ratio is 5%~15%, used in combination with alkaline auxiliaries or chelating agents, with significant effect on stripping mineral oil and carbon deposits. Cosmetic Emulsifier: Used in O/W systems such as creams and lotions, recommended dosage is 1%~5% of the formulation. It can be combined with low HLB emulsifiers (such as MOA-2) to adjust the system HLB value, and can also be used for solubilizing essential oils and fragrances. Emulsion Polymerization: In acrylate or styrene-acrylic emulsion polymerization, used as an emulsifier and stabilizer, recommended dosage is 1%~3% of the total monomer amount, obtaining polymer emulsions with fine particle size and good stability. Paper Deinking: Added in the pulping or flotation stage, usually at 0.2%~0.5% (based on absolutely dry waste paper), helping to improve deinking efficiency and pulp brightness. Precautions Operational Protection: The product is classified as a skin and eye irritant (H315/H319). Please be sure to wear chemical protective gloves, protective goggles, and use in a well-ventilated environment during operation. Wash hands thoroughly after handling. Storage Conditions: Recommended storage temperature is 5°C to 40°C, sealed and stored in a cool, dry place. When the temperature exceeds 40°C, the waxy solid may soften, which is a normal physical phenomenon and does not affect quality. Keep away from strong oxidizers, strong acids, and ignition sources. Emergency Measures: In case of eye contact, immediately rinse thoroughly with clean water for at least 15 minutes and remove contact lenses if any. If irritation persists, seek medical attention immediately. In case of spillage, absorb and collect with inert materials such as sand, and prevent discharge into drains or water bodies. Ecological Impact: This product has low toxicity to aquatic organisms (fish LC50 10~100 mg/L), water hazard class WGK 1. However, direct discharge into the environment without treatment should still be avoided.
