Question 2

What to do if problems occur during the use of PEG200MO, Polyethylene Glycol 200 Monooleate? How to obtain technical support?

Accepted Answer

When problems occur with PEG200MO, first investigate the operating conditions based on the type of issue, and if necessary, contact the Guoli Chemical technical team for professional support. Common Usage Issues and Troubleshooting Suggestions 1. Unsatisctory emulsification or emulsion stratification As a nonionic O/W emulsifier, the emulsification effect of PEG200MO is influenced by HLB value, oil phase properties, aqueous phase conditions, and ratios. Please check: whether the correct emulsion system has been selected (this product is suitable for O/W emulsions); whether the oil-to-water phase ratio is reasonable; whether the emulsification temperature is appropriate (recommended 40–70°C); and whether adequate homogenization or stirring processes have been applied. If the effect is poor when used alone, try compounding with emulsifiers of low HLB values (such as PEG200DO) to achieve broader emulsification adaptability. 2. Product stratification, turbidity, or precipitation The normal appearance of PEG200MO is a light yellow to yellow viscous liquid. If phase separation or turbidity occurs after storage, it may be due to prolonged exposure to extreme temperatures—recommended storage temperature is 5°C to 35°C, avoiding freezing or high heat. If slight stratification occurs, gently stir at room temperature to restore uniformity; if irreversible precipitation or rancid odor occurs, the product may have exceeded the 12-month shelf life or been stored improperly; discontinue use and replace with a new batch. 3. Poor compatibility with other components in the system This product is a nonionic surctant and theoretically has good compatibility with anionic, cationic, and other nonionic surctants. If compatibility issues arise, check: whether strong acids, strong bases, or strong oxidizers (incompatible substances) are present in the system; whether the pH is in an extreme range; and whether the addition sequence is reasonable. It is recommended to first mix PEG200MO evenly with the oil phase, then gradually add the aqueous phase for emulsification. 4. Solubilization or dispersion effect lower than expected Please confirm whether the concentration is appropriate—generally, when used as an emulsifier, the dosage is 1%–5% of the total formulation; the specific amount should be determined through small-scale tests based on the type and content of the oil phase. Also, note the effect of feeding temperature on solubilization efficiency; appropriate heating can improve fluidity and enhance dispersion efficiency. 5. Mild skin or eye irritation This product is derived from natural oleic acid and has low irritation, but it may still cause mild reversible irritation to sensitive individuals. Always wear nitrile or neoprene gloves and safety goggles during operation. In case of contact, rinse skin with plenty of water and soap; flush eyes with running water for at least 15 minutes.

Does PEG200MO (Polyethylene Glycol 200 Monooleate) meet environmental requirements? Can a test report be provided?

Accepted Answer

PEG200MO (Polyethylene Glycol 200 Monooleate) has good environmental attributes and meets general environmental requirements, but specific compliance and test reports need to be confirmed based on your application scenario and regional regulations. Detailed Description PEG200MO (Polyethylene Glycol 200 Monooleate, CAS: 9004-96-0) is produced by Guoli Chemical. From the chemical structure and toxicological data of the product itself, its environmental characteristics are relatively ideal. According to official product data, this product is not classified as a dangerous chemical under the United Nations' Globally Harmonized System of Classification and Labelling of Chemicals (GHS), which indicates that it is not considered a substance with significant harm to the environment during normal transportation, storage, and use. In terms of ecotoxicology, PEG200MO has extremely low acute toxicity (rat oral LD₅₀ > 5000 mg/kg), lling into the low toxicity category. Its molecule consists of a polyethylene glycol (PEG) chain and naturally derived oleic acid. The PEG segment is generally considered biodegradable, and oleic acid, as a natural tty acid, is also easily decomposed by environmental microorganisms. Therefore, PEG200MO is inherently an environmentally friendly nonionic surctant. However, its final environmental compliance (e.g., whether it fully meets EU REACH certification or the emission standards of specific countries) needs to be assessed based on your specific application scenario, as it depends on the synergistic effects of other components in the formulation and the exposure risk assessment of the final product. Regarding the test report you are concerned about, I am currently unable to directly retrieve uploaded third-party environmental test reports (such as SDS/MSDS reports, biodegradability test reports, REACH compliance declarations, etc.) from the database. Such controlled documents are usually issued separately by the manucturer based on batch and customer requirements. Since different downstream applications (e.g., cosmetics, pesticides, industrial processing) have vastly different requirements for environmental testing, the most direct and effective way is to contact Guoli Chemical's sales or technical department, describe your specific application scenario and target market, and they will provide you with an accurate compliance statement or corresponding test report for this product. Application Suggestions To help you advance the environmental compliance assessment of PEG200MO, it is recommended to follow these steps: Clarify Requirements: Determine whether you need a general MSDS or a specific standard report, such as: EU Cosmetics Regulation (EC) No 1223/2009, Pesticide Adjuvant Environmental Assessment, or OECD 301 Series Biodegradability Test Report. Contact the Manucturer: Directly contact Guoli Chemical, providing your product and application information. The manucturer's technical team can evaluate the environmental performance of PEG200MO in your formulation based on your needs, and provide compliance certificates or arrange specific third-party testing for that batch of product. Explore Alternatives: If you encounter difficulties with specific extremely stringent environmental certifications (such as Ecolabel or COSMOS natural certification), you can consult with Guoli Chemical engineers. They have a complete product line of esters and can recommend products with similar HLB values but derived from a higher proportion of renewable carbon or with certifications. Technical Parameters (Core Parameters Related to Environmental Protection) The following are key indicators related to environmental protection and safety compiled from database information for your preliminary reference: ParameterValue/DescriptionEnvironmental Significance GHS ClassificationNon-hazardous chemicalIndicates no significant harm to human health and the environment, with fewer restrictions on transportation and storage.

Question 5

What are the advantages of PEG200MO (Polyethylene Glycol 200 Monooleate) compared with other similar products?

Accepted Answer

PEG200MO (Polyethylene Glycol 200 Monooleate) is a nonionic surctant with core advantages of high-purity monoester structure, excellent formulation compatibility, and mild safety, particularly suitable for high-end formulation systems requiring high emulsification efficiency and low physiological irritation. Detailed Description PEG200MO is prepared by esterification of polyethylene glycol 200 and natural oleic acid. Its molecular structure achieves a delicate balance between hydrophilic groups (PEG chain, n≈4) and hydrophobic groups (oleic acid carbon chain). Compared with similar products, the most prominent differentiated advantage lies in its monoester content ≥95%, and diester content ≤3%. This high monoester ratio imparts superior self-emulsifying ability and emulsion stability to the product, as monoester molecules exhibit stronger intercial adsorption tendency, capable of more efficiently reducing the oil/water intercial tension (surce tension of 1% aqueous solution is only 30~35 mN/m), while diester by-products tend to enter the oil phase, contributing less to emulsification. Among similar polyethylene glycol tty acid ester products, the HLB value of PEG200MO is approximately 8, lling within the critical transition range from water-in-oil (W/O) to oil-in-water (O/W) emulsions. This property allows it to be used alone to prepare W/O emulsions or synergistically with high-HLB emulsifiers to construct stable O/W systems, offering a much wider application scope than competing products with single HLB value ranges. Additionally, this product is derived from natural oleic acid, featuring extremely low irritation (oral LD₅₀ > 5000 mg/kg). Compared with some synthetic tty acid esters or similar products with higher EO numbers, it has a significant mildness advantage in the cosmetics and personal care fields. Furthermore, the product exhibits good permeability (canvas settling time ≤ 60 seconds) and low foaming characteristics, making it outstanding in industrial scenarios requiring rapid wetting but not prone to foaming (e.g., metalworking fluids, textile leveling agents), outperforming some high-foaming PEG esters. Its active content is ≥99%, and free alcohol ≤2%, meaning a higher concentration of active ingredients per unit dosage, which can reduce formulation addition levels and achieve a balance between cost and performance.

Recommended addition level is generally 2%~8%. Compounding with high-HLB emulsifiers (e.g., PEG-40 Hydrogenated Castor Oil) can achieve broader formulation adaptability and a finer skin feel. The high purity also allows formulators to precisely quantify, avoiding uncertainties introduced by diester impurities. Metalworking Fluids: As a key component of emulsified cutting fluids and rust inhibitors, this product can quickly form stable emulsions. Its low foaming property avoids foam issues in high-pressure spray systems, and good permeability helps the lubricant quickly reach the cutting interce, improving machining accuracy. Recommended addition level is 5%~15% in the concentrate. Textile Auxiliaries: In spin finishes and leveling agents, the low foam, high permeability, and excellent dispersibility of PEG200MO can significantly improve fiber spinnability and dye leveling effect. Its easy water solubility cilitates subsequent washing processes, reducing residues. Pesticide Formulations: In emulsion in water (EW) and microemulsion (ME) formulations, this product effectively promotes uniform dispersion of pesticide active ingredients, improves dilution stability, and enhances the wetting and spreading of the spray liquid on plant leaf surces. Recommended dosage is 3%~10% of the total formulation weight. Precautions The product is slightly hygroscopic; after opening, seal it promptly for storage. Recommended storage temperature: 5°C~35°C; avoid prolonged exposure to extreme high temperatures or freezing conditions. Under strong acid or strong alkali environments (pH12), ester bond hydrolysis may occur, leading to decreased emulsification performance. It is recommended to use within pH 4~10 for optimal stability. Although the product is not flammable (open cup flash point >150°C), it should still be kept away from open flames and strong oxidizers. Protective gloves and goggles are recommended during operation to avoid prolonged skin contact. This product is not a hazardous chemical and does not ll under GHS classification, but general chemical handling practices and good ventilation in the workplace should be followed.

Question 6

How to store PEG200MO, Polyethylene Glycol 200 Monooleate? What is the shelf life?

Accepted Answer

PEG200MO should be stored sealed in a cool and dry place, recommended temperature 5°C–35°C, shelf life at least 12 months from the date of production. Detailed Description PEG200MO (Polyethylene Glycol 200 Monooleate) is a chemically stable non-ionic surctant, but under improper storage conditions, it may still experience issues such as moisture absorption, oxidation, or phase separation. This product has a certain hygroscopicity. Prolonged exposure to high-humidity environments will cause it to absorb moisture from the air, leading to increased water content in the product, which may affect its emulsifying performance and formulation effectiveness. Additionally, although the product has an open-cup flash point greater than 200°C and is not classified as a flammable liquid, it is still recommended to keep it away from open flames and high-temperature heat sources to ensure storage safety. PEG200MO is produced by esterifying natural oleic acid with polyethylene glycol. Its molecular structure contains unsaturated double bonds and ester bonds. Under extreme high temperature or prolonged light exposure, the unsaturated bonds in the oleic acid chain may undergo slow oxidation, resulting in color deepening and increased acid value. Under freezing conditions (below 0°C), the product may become cloudy or undergo phase separation. Although it can usually recover after warming, repeated freeze-thaw cycles may adversely affect emulsion stability. Therefore, stable storage temperature is key to ensuring product performance. Under recommended storage conditions and following the "first-in, first-out" inventory management principle, Guoli Chemical guarantees the stability of this product for at least 12 months from the date of production. For products beyond this shelf life, if there is no obvious change in appearance, it is recommended to verify performance through small-scale tests before use.

Upon receipt, check the integrity of the packaging to confirm no leakage or seal damage. After opening for use, immediately reseal to minimize contact with air. If sub-packaging is needed during use, use containers compatible with the original packaging and label them properly (product name, batch number, sub-packaging date). Notes Empty containers may contain product residues; do not use for other materials without thorough cleaning. The product may become cloudy or viscous at low temperatures; this is a normal physical phenomenon. It generally recovers after warming to room temperature and appropriate stirring, without affecting performance. If the product shows obvious separation, off-odor, or significant color darkening, discontinue use and conduct quality evaluation. This product is not a hazardous chemical and is non-flammable, but standard chemical handling practices should still be followed.

Question 8

How to use PEG200MO, Polyethylene Glycol 200 Monooleate? What is the recommended dosage?

Accepted Answer

As a nonionic O/W emulsifier, the typical recommended dosage of PEG200MO is 1% to 8% of the total formulation weight. The specific dosage should be determined through experimental optimization based on the application system and the object to be emulsified. Detailed Description PEG200MO (Polyethylene Glycol 200 Monooleate) is a light yellow to yellow transparent liquid with an HLB value of approximately 8. It is a strongly lipophilic nonionic surctant, especially suitable for preparing O/W (oil-in-water) emulsion systems. The product has an active content ≥99.0%, is easily dispersible in water, and exhibits good formulation compatibility. It can be flexibly compounded with anionic, cationic, and other nonionic surctants. In practical use, PEG200MO is typically used as an emulsifier, wetting agent, or dispersant. It can be directly added to the oil phase and dissolved by heating (recommended heating to 40~60°C), then mixed with the water phase for homogenization emulsification. Alternatively, it can be pre-mixed uniformly with the oil phase components and then slowly added to the water phase under stirring to form an emulsion. For systems requiring high-shear dispersion (e.g., pesticide microemulsions, metalworking fluids), high-shear or homogenization equipment is recommended to fully leverage its emulsifying and dispersing performance. The Guoli Chemical database does not contain precise recommended dosage parameters for each specific application field. The following recommended dosages are based on the product's HLB value (8) and typical industry application experiences. It is recommended that users conduct gradient experiments in actual formulations to determine the optimal dosage. Technical Parameters Parameter NameValue/Description AppearanceLight yellow to yellow transparent liquid Ionic TypeNonionic HLB Value8 (Suitable for O/W emulsification) Active Content≥99.0% Monoester Content≥95% pH Value (1% Aqueous Solution)5.0~7.0 Cloud Point40~60°C Acid Value≤5 mgKOH/g Saponification Value115~125 mgKOH/g Density (25°C)1.11~1.13 g/cm³ Kinematic Viscosity (25°C)100~200 mm²/s Flash Point (Open Cup)>150°C Surce Tension (1% Aqueous Solution, 25°C)30~35 mN/m Foam PropertiesLow Foaming Penetration Power (Canvas Settling Time)≤60 seconds Application Recommendations 1. Cosmetics and Personal Care Products (Creams, Lotions, Makeup Removers, Body Washes) Recommended Dosage: 1%~5% (based on total formulation weight). As an O/W emulsifier, mix PEG200MO uniformly with oil phase components (e.g., oils, silicone oils) at 40~60°C, then homogenize with the water phase. To enhance emulsion stability, it is recommended to combine with a co-emulsifier having a higher HLB value (e.g., PEG-40 Hydrogenated Castor Oil). 2. Metalworking Fluids (Emulsified Cutting Fluids, Rust Inhibitors) Recommended Dosage: 5%~15% (based on total concentrate weight). PEG200MO provides stable lubricating emulsions, reduces tool wear, and improves rust inhibition. It is typically formulated with base oils, rust inhibitors, and extreme pressure additives. High-shear emulsification equipment is recommended to ensure uniform droplet size. 3. Textile Auxiliaries (Spinning Oils, Leveling Agents) Recommended Dosage: 1%~3% (based on total working solution weight). Used to improve fiber spinnability and lubricity, and promote uniform dye dispersion and retardation. It can be directly added to the spinning oil or leveling agent formulation and stirred evenly before use. 4. Pesticide Formulations (Emulsion in Water EW, Microemulsion ME) Recommended Dosage: 3%~8% (based on total formulation weight). As a key emulsifying adjuvant, premix PEG200MO with the pesticide technical and solvent, then add to water with shear emulsification. This effectively improves the dilution stability of the formulation and the wetting and spreading of the spray liquid on plant leaves. Summary of Addition Methods Direct Addition Method: Add PEG200MO directly into the formulation system and stir or homogenize until uniformly dispersed. Oil Phase Premixing Method (Recommended for Emulsion Systems): Preheat and mix PEG200MO with oil phase components (40~60°C), then mix with the water phase for emulsification. This significantly improves emulsification efficiency and emulsion stability. Combination Use: Its nonionic nature allows good compatibility with anionic, cationic, and other nonionic surctants, enabling flexible adjustment of the HLB value to meet the emulsification requirements of different oil phases. Precautions PEG200MO may undergo hydrolysis under strong acidic or alkaline conditions, affecting its performance. It is recommended to use within a pH range of 5~9 for optimal performance stability. The product has a cloud point of 40~60°C. In high-temperature application scenarios, pay attention to phase behavior changes and avoid exceeding the cloud point temperature to prevent a decrease in emulsification performance. Storage temperature is recommended to be 5°C~35°C. Avoid prolonged exposure to extreme high temperatures or freezing conditions to prevent phase separation or performance changes. The product is slightly hygroscopic. Seal the packaging container promptly after use to avoid prolonged exposure to high humidity environments.

Accepted Answer

PEG200MO (Polyethylene Glycol 200 Monooleate) is mainly applied in four major industries: personal care and cosmetics, textile industry, metalworking fluids, and pesticide formulations. In various formulations, it plays key roles as an emulsifier, dispersant, wetting agent, and solubilizer. Detailed Description PEG200MO is a nonionic surctant produced by esterification of polyethylene glycol with natural oleic acid. It appears as a light yellow to yellow viscous liquid. Due to its excellent emulsifying ability, superior wetting and dispersing properties, outstanding chemical stability, and wide formulation compatibility, this product is widely used in multiple industrial fields. In the personal care and cosmetics industry, PEG200MO is primarily used as an emulsifier in formulations such as creams, lotions, cleansing oils, and body washes. It effectively reduces the intercial tension between oil and water, forming a stable and fine O/W emulsion system, giving the product a delicate texture and comfortable skin feel, while also helping to evenly distribute active ingredients. Due to its natural tty acid origin, it has low irritation to skin and mucous membranes, making it very suitable for personal care and cosmetic formulation design. In the industrial sector, PEG200MO also plays an irreplaceable role. In the textile industry, it is used as an important component in spinning oils and leveling agents; in metalworking fluids, it is a key component in emulsified cutting fluids and rust inhibitors; in pesticide formulations, it helps to uniformly disperse and solubilize active ingredients in emulsion concentrates (EW) and microemulsions (ME). Its nonionic nature allows it to be well combined with anionic, cationic, and other nonionic surctants, flexibly meeting the needs of multi-component systems.

Due to its nonionic nature, PEG200MO can be flexibly combined with anionic, cationic, and other nonionic surctants to achieve synergistic effects. For O/W emulsion systems, it can be used as a primary or auxiliary emulsifier to obtain good results. When used in textile oils, it is recommended to combine with other lubricating components; for pesticide EW and ME formulations, compatibility screening should be carried out based on the characteristics of the active ingredients to ensure thermal and cold storage stability of the formulation. Precautions This product has an open cup flash point above 200°C and is not classified as a flammable liquid, but it is still recommended to store away from open flames and heat sources. It has some hygroscopicity, so prolonged exposure to high humidity environments should be avoided, and the container should be kept tightly sealed during storage. Recommended storage temperature is 5°C to 35°C; avoid prolonged exposure to extreme heat or freezing conditions to prevent phase separation or performance changes. It is resistant to acids, alkalis, and hard water, maintaining stable performance over a wide pH range, making it suitable for various complex formulations. It is recommended to wear chemical protective gloves and safety goggles during operation to avoid prolonged skin contact or eye splashes. Recommended shelf life is at least 12 months from the date of production (under recommended storage conditions, following the first-in-first-out principle).
