Question 1

Is MOA-9P lauryl alcohol polyoxyethylene ether phosphate harmful to humans? Does it have an impact on the environment?

Accepted Answer

MOA-9P is a low-toxicity chemical with moderate to severe irritation to the skin and eyes, but it has low toxicity to aquatic organisms and is easily biodegradable. Under standardized operation and proper disposal, its impact on the environment is controllable. Detailed Explanation MOA-9P (lauryl alcohol polyoxyethylene ether phosphate) is a low-toxicity substance under normal industrial use conditions. According to toxicological data, the acute oral toxicity LD₅₀ in rats is greater than 2000 mg/kg, classifying it as low-toxicity, and the guinea pig maximization test shows no skin sensitization. However, special attention is needed as this product is classified by GHS as a skin corrosive substance, causing moderate skin irritation (rabbit skin irritation index PII 2.0 to 4.0) and moderate to severe eye irritation, which may even lead to corneal damage. Therefore, the risk of direct contact cannot be ignored. In terms of environmental impact, MOA-9P performs relatively well. Ecotoxicological tests indicate low toxicity to aquatic organisms — the 96-hour LC₅₀ for zebrafish is greater than 100 mg/L. More importantly, this product has excellent biodegradability, with a degradation rate exceeding 80% after 28 days in the OECD 301B standard test, classifying it as readily biodegradable, with no bioaccumulation and no enrichment in the food chain. Overall, the main risk of MOA-9P to humans lies in local irritation injury from direct contact rather than systemic toxicity; its potential impact on the environment is mainly the short-term load on water bodies from untreated discharge. However, due to its easy degradation characteristics, the long-term ecological risk is low. The key lies in standardized operation and proper disposal.

However, formulators must wear protective gloves and goggles during mixing and operate in a well-ventilated environment. Industrial applications (textiles, leather, metalworking, etc.): Operators should wear chemical-resistant gloves, safety goggles, and protective clothing throughout, with local exhaust ventilation in the workplace. When used in metalworking fluid formulations, attention should also be paid to compatibility with other additives. Pesticide formulations: When used as an emulsifying dispersant, care should be taken to avoid splashing during preparation. After field application, its rapid degradation in the environment helps reduce residues. Emulsion polymerization: Use in a closed reactor system effectively reduces exposure risks, but personal protection is still required during feeding and sampling. Precautions Skin contact: Immediately remove contaminated clothing and rinse with plenty of running water and soap for at least 15 minutes. Seek medical attention immediately if irritation or burns occur. Eye contact: Immediately lift eyelids and rinse continuously with plenty of running water or saline for at least 15 minutes. Do not use ointments; seek immediate medical attention. Spill handling: For small spills, absorb with inert materials such as sand or vermiculite and collect; for large spills, contain and prevent entry into drains, soil, or water bodies. Waste disposal: Treat as hazardous waste and hand over to qualified units for harmless treatment according to regulations. Do not pour into drains or natural water bodies. Storage conditions: Recommended temperature 5°C to 35°C, cool, dry, well-ventilated, containers tightly closed, protected from light, and away from strong oxidizing agents and strong acids.

Question 2

What should I do if problems occur during the use of MOA-9P laureth phosphate? How to obtain technical support?

Accepted Answer

If you encounter problems while using MOA-9P, it is recommended to first perform self-inspection based on the application scenario. If the problem cannot be resolved, contact the technical support team of Hai'an Guoli Chemical Co., Ltd. directly for professional guidance. Common Problem Self-Inspection and Troubleshooting Guide As an anionic phosphate ester surctant, problems with MOA-9P laureth phosphate in different application scenarios are usually related to system compatibility, process conditions, or storage methods. Below are common problems and troubleshooting directions based on various application fields: Poor emulsification or dispersion performance (involving personal care products, pesticide formulations, emulsion polymerization, etc.): First, check whether the product is within the shelf life and stored under compliant conditions (cool and dry, sealed storage at 5°C to 35°C). Moisture absorption or prolonged high temperature may lead to performance degradation. Second, verify the pH of the formulation system — the pH of a 1% aqueous solution of MOA-9P ranges from 1.5 to 3.0. Mismatched pH may affect emulsification stability. It is recommended to check whether the system contains strong acids, strong bases, or high-concentration electrolytes, as these ctors may damage the phosphate ester bond structure. Finally, the HLB value is about 11-12. If the required HLB value of the oil phase being emulsified deviates significantly, adjustment of dosage or combination with other emulsifiers is recommended. Abnormal foam or insufficient cleaning power (involving personal care products such as shampoos, body washes, cial cleansers, etc.): MOA-9P has moderate foam with good stability. If the foam volume decreases significantly, check for antagonistic effects with other surctants, especially cationic conditioners that may form insoluble precipitates. It is recommended to reduce the dosage of cationic ingredients in the formulation or adjust the addition order. If cleaning power is insufficient, consider increasing the dosage of MOA-9P or combining it with primary surctants such as alkyl polyoxyethylene ether sulte (AES) for synergistic enhancement. Decreased lubricity or rust prevention performance in metalworking fluids: The monoester content of MOA-9P is ≥80%, with phosphorus content (calculated as P₂O₅) of 8%-12%. These parameters are directly related to extreme pressure lubrication and rust prevention effects. If performance declines, confirm whether the dilution ratio and pH exceed the stable range, and whether the working fluid has been exposed to high temperatures or direct light for a long time. It is recommended to regularly test the concentration and pH of the working fluid and replenish with fresh fluid in a timely manner. Weakened antistatic effect in textile oil applications: Static problems in textile processing are often related to fiber moisture content and environmental humidity. MOA-9P has relatively low hygroscopicity. If workshop humidity is too low (below 40% RH), the antistatic effect may decrease. It is recommended to increase the use concentration appropriately or combine it with auxiliary antistatic agents with stronger hygroscopicity.

Question 8

How to use MOA-9P Laureth-4 Phosphate? What is the recommended dosage?

Accepted Answer

MOA-9P is an anionic phosphate ester surctant, easily soluble in water. When using, it is usually diluted with deionized water to a 10%~20% solution before adding to the system; the recommended dosage varies significantly depending on the application field, generally between 1%~10%. Detailed Description MOA-9P Laureth-4 Phosphate (CAS: 39464-66-9) is a colorless to light yellow transparent liquid at room temperature, with medium viscosity, and easily soluble in water. Since the original product is strongly acidic (1% aqueous solution pH value is only 1.5~3.0), direct addition to the formulation system may cause local pH drop or gel formation. Therefore, it is recommended to slowly add it to pre-prepared deionized water under stirring, dilute to a 10%~20% stock solution, then neutralize to the required pH with a dilute base (e.g., NaOH, KOH, or triethanolamine) before use. If the formulation itself is an alkaline system, it can be added directly under sufficient stirring and fully neutralized. This product possesses dual characteristics of nonionic and anionic surctants, with an HLB value of 11~12, and outstanding emulsifying, wetting, and dispersing capabilities. Attention should be paid when adding at different process stages: when used as an emulsifier, it should be added before mixing the oil and water phases; when used as an antistatic agent or lubricating additive, it is usually added in the later mixing stage of the aqueous system. The product remains stable over a wide pH range and under high hardness water conditions, but is not resistant to strong bases. The phosphate ester bond is prone to hydrolysis under strongly alkaline conditions, so prolonged exposure to environments with pH >10 should be avoided.

Specific usage amounts should be determined through small-scale and pilot-scale tests, and attention should be paid to adjusting the system pH to ensure optimal performance of the product. Precautions Safety Protection: This product is a skin corrosive substance, moderately irritating to the skin (PII=2.0~4.0), and can cause severe eye damage. Wear chemically resistant gloves, safety goggles, and protective clothing during operation. Use in a well-ventilated area. pH Adjustment: The original product is strongly acidic. Direct large-scale addition may adversely affect other components in the formulation. Be sure to dilute and neutralize first or add slowly in portions with stirring. Storage Conditions: Keep in sealed packaging, store in a cool, dry place at 5℃~35℃, away from direct sunlight and high temperatures, and away from strong oxidizing agents and strong alkaline substances. Compatibility Test: In complex formulation systems, it is recommended to conduct small-scale compatibility tests first to confirm stable compatibility with other surctants and additives before scaling up production.

Question 9

What are the main industries and processes where MOA-9P lauryl alcohol polyoxyethylene ether phosphate is used?

Accepted Answer

MOA-9P lauryl alcohol polyoxyethylene ether phosphate is widely used in six major industries: personal care, textiles, leather, metalworking fluids, pesticide formulations, and emulsion polymerization. It is a multifunctional phosphate ester surctant with both anionic and nonionic characteristics. Detailed Description MOA-9P (CAS number: 39464-66-9) is an anionic phosphate ester surctant prepared by modifying lauryl alcohol polyoxyethylene ether with phosphoric acid esterification. It appears as a colorless to pale yellow transparent liquid. Its unique molecular structure gives it the dual characteristics of both nonionic and anionic surctants, exhibiting excellent compatibility and functional synergy in various formulation systems, thus being widely used in many industrial fields. The core functional advantages of this product are: excellent emulsifying properties efficiently stabilize the oil-water interce, suitable for preparing fine and stable emulsion systems; superior wetting and dispersing capabilities significantly reduce intercial tension, promoting uniform distribution of active ingredients in the system; at the same time, it has outstanding resistance to acids, alkalis, and hard water, maintaining stable performance under a wide pH range and high hardness water conditions without deactivation or precipitation. In addition, its good foaming and foam stabilizing properties, as well as extreme pressure lubrication and anti-rust functions, further expand its application boundaries. From a toxicological and environmental perspective, MOA-9P is low in toxicity (rat oral LD₅₀ > 2000 mg/kg), readily biodegradable (28-day biodegradation rate > 80%, OECD 301B test method), low toxicity to aquatic organisms (zebrafish 96-hour LC₅₀ > 100 mg/L), and has no bioaccumulation potential. However, it should be noted that it is moderately irritating to the skin and can cause severe eye damage; protective measures must be taken during handling. Detailed Explanation of the Six Core Application Industries and Processes 1. Daily Chemical Industry (Personal Care) MOA-9P is used as a supertting agent and emulsifier in formulations of high-end shampoos, body washes, cial cleansers, etc. It provides mild cleansing effects while imparting a moisturizing and comfortable skin feel, avoiding the dryness caused by excessive degreasing of traditional anionic surctants. Its good foaming and foam stabilizing properties also help enhance the foam texture of the product. 2. Textile Industry MOA-9P is a key component in synthetic fiber spinning oils, mainly functioning as an antistatic agent and softener. It effectively eliminates static electricity generated during the production and use of synthetic fibers, improving fiber spinnability and post-processing performance; at the same time, it imparts a soft and smooth hand feel to brics, enhancing the quality and wearing comfort of textiles. 3. Leather Processing In leather processing, MOA-9P is used as a tting agent and penetrant. It helps oils penetrate deeply and evenly into leather fibers, making the leather more supple and full, while also improving its physical strength and water resistance. It is an important functional additive in the leather tting process. 4. Metalworking Fluids In formulations of cutting fluids, grinding fluids, and other metalworking fluids, MOA-9P serves as an extreme pressure lubricant additive and anti-rust additive. Under extreme working conditions such as metal cutting and grinding, it forms an effective boundary lubrication protective film at the workpiece-tool interce, reducing friction and wear; it also prevents rust on workpiece and machine tool surces, prolongs tool life, and improves machined surce quality. 5. Pesticide Formulations MOA-9P is used as an emulsifying dispersant in pesticide formulations for preparing emulsifiable concentrates (EC) and oil-in-water emulsions (EW). It helps the active ingredients of pesticides disperse quickly and uniformly in water, forming stable emulsions, preventing oil-water separation and degradation of active ingredients, thereby ensuring stable and consistent field application effects. 6. Emulsion Polymerization In emulsion polymerization reactions of acrylate, styrene-acrylic, and other systems, MOA-9P is used as a high-efficiency emulsifier. It plays a key role in stabilizing monomer droplets and polymer latex particles, helping to control polymer particle size distribution and reaction progress, ultimately affecting the stability and application performance of the emulsion product.

Question 10

What are the physicochemical technical parameters of MOA-9P (Lauryl Alcohol Polyoxyethylene Ether Phosphate)?

Accepted Answer

MOA-9P (Lauryl Alcohol Polyoxyethylene Ether Phosphate) is an anionic phosphate ester surctant, appearing as a colorless to light yellow transparent liquid, with an HLB value of 11-12, excellent water solubility and surce activity, and multiple physicochemical parameters showing good formulation compatibility. Detailed Description MOA-9P (Lauryl Alcohol Polyoxyethylene Ether Phosphate, CAS: 39464-66-9) is an anionic surctant produced by phosphation of lauryl alcohol polyoxyethylene ether, with a molecular weight of approximately 650 and a molecular formula that can be expressed as C12-14H25-29O(C2H4O)nH (n≈9). This product appears as a colorless to light yellow transparent liquid, is easily soluble in water, has a density of about 1.05 at 25°C, a kinematic viscosity of about 100-200 mm²/s, and is a medium-viscosity liquid. Its active content is ≥95%, solid content ≥98%, free alcohol ≤3%, free phosphoric acid ≤2%, with strict quality control. From a structural perspective, MOA-9P possesses both non-ionic segments (polyoxyethylene chain) and anionic groups (phosphate ester group), with monoester content ≥80%, diester content ≤20%, and combined phosphorus content of 8-12% (calculated as P2O5). The acid value of the product is 130~170 mgKOH/g, saponification value about 230~260 mgKOH/g, hydroxyl value ≤5 mgKOH/g, iodine value ≤2, unsaturation ≤0.5 meq/g, indicating extremely low unsaturated bond content in the molecular structure and good chemical stability. It should be noted that its phosphate ester bond is not resistant to strong acid or alkali environments and is prone to hydrolysis under extreme pH conditions. In terms of surce activity indicators, the HLB value of MOA-9P is 11-12, the surce tension of a 1% aqueous solution is about 30-35 mN/m (25°C), and the critical micelle concentration (CMC) is about 0.01-0.1 g/L, showing good surce activity efficiency. The pH of both 1% and 5% aqueous solutions is in the range of 1.5~3.0, exhibiting acidic characteristics. The foaming performance of the product is moderate foam with good stability, excellent penetrating power, flash point >150°C, slight hygroscopicity, melting point below 0°C, and remains liquid within the normal usage temperature range, cilitating handling and formulation.
