Question 4

Does PEG600MO (Polyethylene Glycol 600 Monooleate) meet environmental requirements? Can a test report be provided?

Accepted Answer

PEG600MO has good biodegradation potential, but there is no specific environmental test report in the database. For specific reports, please contact Guoli Chemical. Detailed Explanation PEG600MO (Polyethylene Glycol 600 Monooleate) is a nonionic surctant produced by esterifying natural oleic acid with polyethylene glycol. Since the raw material contains natural tty acid components, this product has good biodegradation potential in the environment. In particular, its tty acid ester bond can be hydrolyzed by microorganisms, and the oleic acid part can degrade quickly. Compared with fully synthetic surctants, PEG600MO has certain advantages in environmental attributes. However, regarding whether it fully complies with specific environmental regulations (such as EU REACH, OECD biodegradation test standards, China's Environmental Management of New Chemical Substances, etc.), currently, there is no specific environmental test report (such as OECD 301 series biodegradability test reports, aquatic toxicity test reports, VOC content test reports, etc.) for this product in the Guoli Chemical product database. Whether it meets the specific environmental access requirements of your industry or region depends on the regulatory framework of the target market and the end-use application scenario. If you need formal environmental compliance certification documents or third-party test reports, it is recommended to directly contact the sales or technical department of Guoli Chemical, providing your specific application, target market, and required test items, so that applicable compliance documents can be matched or arrangements for sample testing can be made. Technical Parameters Below are the known technical parameters related to environmental assessment for PEG600MO (Data source: Guoli Chemical product database): Parameter Item Value/Description Environmental Relevance Raw Material Source Natural oleic acid + Polyethylene glycol Contains renewable natural components, beneficial for biodegradation Active Content ≥99% High purity, low impurity content Free Alcohol Content ≤3% Residual monomer controllable Heavy Metals ≤10 mg/kg Complies with general industrial product requirements Arsenic ≤2 mg/kg Complies with general industrial product requirements Biodegradability Test Report No database record at present Need to obtain separately Aquatic Toxicity Test Report No database record at present Need to obtain separately Application Suggestions Based on the structural characteristics of PEG600MO and industry experience, in application scenarios with high environmental requirements: Personal Care Products & Cosmetics: The environmental focus in this field is usually on the renewability of raw materials and the biodegradability of end products. Since PEG600MO uses natural oleic acid as raw material, it is more vored by formulators compared to fully synthetic esters. If the product is for export to the EU, attention should be paid to REACH registration status. It is recommended to request the relevant registration number or compliance statement. Industrial Cleaning & Metalworking Fluids: If the end application involves wastewater discharge, biodegradability is a key indicator. As a nonionic tty acid ester, PEG600MO theoretically has good primary biodegradability (ester bond is easily hydrolyzed), but ultimate biodegradation data should be based on actual test reports. Pesticide Emulsifiers: Environmental review of pesticide adjuvants is becoming increasingly stringent. Some countries and regions require that adjuvants also pass environmental te assessments. It is recommended to confirm local registration requirements before use. Precautions The Safety Data Sheet (SDS) of this product indicates that during leakage, the product should be prevented from entering sewers or water bodies, and environmental release should be avoided during operation. PEG600MO has a certain potential for aquatic organism irritation (GHS classification includes eye irritation and skin irritation). In environmental risk assessment, attention should be paid to its possible effects on aquatic ecosystems. If formal environmental test reports are needed (such as OECD 301B biodegradability, OECD 201/202/203 aquatic toxicity, VOC content, etc.), please directly contact the technical department of Guoli Chemical, informing them of the specific test requirements and target market, so as to obtain the latest compliance documents.

Question 10

What are the physical and chemical technical parameters of PEG600MO (Polyethylene Glycol 600 Monooleate)?

Accepted Answer

PEG600MO (Polyethylene Glycol 600 Monooleate) is a nonionic surctant with an HLB value of approximately 13.5, combining excellent hydrophilicity and lipophilicity. Its physical and chemical parameters cover multiple dimensions, from appearance and solubility to intercial chemical properties. Detailed Description PEG600MO is a nonionic surctant produced by the esterification of polyethylene glycol 600 with natural oleic acid. It appears as a light yellow to yellow liquid or paste (freezing point approximately 5~10°C). Its molecular structure features a balanced distribution of hydrophilic groups (polyoxyethylene chain, n≈13) and lipophilic groups (oleate ester group), imparting excellent self-emulsifying ability and broad compatibility. The product is readily soluble in polar solvents such as water, ethanol, and acetone. The cloud point of a 1% aqueous solution is ≥60°C, making it a medium-to-high temperature applicable emulsifier. The active content of this product is ≥99%, monoester content ≥95%, diester content ≤5%, free alcohol ≤3%, acid value ≤2.0 mgKOH\/g, saponification value 60~80 mgKOH\/g, hydroxyl value 70~95 mgKOH\/g, and iodine value 30~40 gI₂\/100g, indicating controlled unsaturation in the molecule. The pH of a 1% aqueous solution ranges from 5.0 to 7.0, close to the natural pH of human skin, making it suitable for personal care formulations. In terms of intercial chemical properties, the surce tension of a 0.1% aqueous solution is approximately 35 mN\/m, and the critical micelle concentration (CMC) is about 0.04 mmol\/L, demonstrating good surce activity efficiency. The product is low-foaming, with a kinematic viscosity of approximately 150 mm²\/s at 40°C and a low-shear viscosity of 150~250 mPa·s at 25°C. The flash point is >200°C, and it is chemically stable under normal conditions, but the product has some hygroscopicity and is not resistant to strong alkalis.

Leveraging its mild pH of 5.0~7.0, it provides stable emulsification and a emollient skin feel. Agrochemical Formulations: Used as an agricultural emulsifier. With a low CMC value (approximately 0.04 mmol\/L), it effectively reduces oil-water intercial tension, helping to uniformly disperse active ingredients in water-based systems. Metalworking Fluids: Acts as a dual-function emulsifying and lubricating component in cutting fluids and grinding fluids. Its viscosity characteristics (150 mm²\/s at 40°C) can provide auxiliary boundary lubrication. Industrial Cleaning: Utilizes its emulsifying and dispersing ability for mineral oils and animal\/vegetable oils, enhancing the detergency of water-based cleaners. The low-foaming property also cilitates rinsing. Pharmaceutical Industry: Used as a solubilizer for poorly soluble drugs. A hydroxyl value of 70~95 mgKOH\/g and monoester content ≥95% ensure reliable solubilization performance. Precautions Storage Temperature: Given a freezing point of approximately 5~10°C, storage in winter should be maintained above 5°C to avoid solidification and clumping; recommended storage temperature is 5~30°C. Limited Alkali Resistance: This product is not resistant to strong alkalis and may undergo hydrolysis in strongly alkaline formulations. Evaluate the pH environment of the formulation in advance. Hygroscopicity Handling: The product is hygroscopic. After opening, it should be sealed and stored immediately to prevent quality degradation due to moisture absorption from the air. Safety Protection: May cause skin, eye, and respiratory irritation (GHS classification H315\/H319\/H335). It is recommended to wear safety goggles and nitrile\/chloroprene gloves during operation and use in a well-ventilated area.
