PEG600DO, is polyethylene glycol 600 dioleate harmful to human body? Does it have any impact on the environment?

PEG600DO (polyethylene glycol 600 dioleate) is a low-toxicity substance with extremely low harm to the human body, high safety under normal use conditions; it has certain biodegradability in the environment, but large-scale leakage into water bodies or soil must be prevented.

Detailed Description

Human Safety

According to the Globally Harmonized System of Classification and Labeling of Chemicals (GHS), PEG600DO (polyethylene glycol 600 dioleate) is not classified as a hazardous chemical. Its acute oral toxicity (rat) LD50 > 5000 mg/kg, belonging to the practically non-toxic level, with no carcinogenicity, mutagenicity, or reproductive toxicity risks. It should be noted that this product may cause mild irritation to skin and eyes (skin irritation Category 2, H315; eye irritation Category 2A, H319). For long-term or repeated direct contact, it is recommended to wear protective gloves and chemical safety goggles. Under normal industrial and daily chemical formulation use conditions, due to its typically low addition levels, the exposure risk to humans is minimal. This product is a non-ionic surfactant variety with high safety, suitable for daily chemical formulations with certain requirements for skin contact.

Environmental Impact

PEG600DO has certain biodegradability and can gradually degrade in the natural environment; it is not a persistent organic pollutant. However, as a surfactant, if large amounts of untreated waste liquid are directly discharged into sewers, water sources or soil, it may still cause short-term load impact on aquatic ecosystems. Therefore, waste liquid containing this product after use should be treated in accordance with local environmental regulations to avoid direct discharge into natural water bodies. Under normal dispersed use (such as field dilution of pesticide formulations, industrial cleaning, etc.) and controlled concentrations, its environmental risk is within a controllable range.

Toxicological and Ecological Parameters

Application Suggestions

Given the low toxicity and mild characteristics of PEG600DO, it has a high safety margin in the following applications:

• Cosmetics and Personal Care: Used as an emulsifier in creams, lotions, and makeup removers, with typical addition levels of 1%-5% in formulations; mild and low-irritation to the skin.
• Textile Industry: Used as a component in spinning oils and antistatic agents; mainly indirect contact during processing, low safety risk.
• Metalworking Fluids: Used in emulsified cutting fluids; operators are advised to wear gloves to avoid prolonged direct immersion contact.
• Pesticide Formulations: After field dilution, the concentration is extremely low, and environmental exposure levels are controllable.
• Industrial Cleaners: Waste liquid after use should be collected and treated to avoid direct discharge.

Precautions

• Wear chemical safety goggles and impermeable gloves (e.g., nitrile or neoprene) during operation.
• Wash hands thoroughly with soap and water after handling.
• If accidentally gets into eyes, flush immediately with plenty of running water for at least 15 minutes; seek medical attention if irritation persists.
• Store in a cool (5-40°C), dry, well-ventilated place away from strong oxidizers and open flames.
• In case of spillage, collect with inert materials such as sand or vermiculite; dispose of waste according to local environmental regulations.
• Strictly prohibit the discharge of large amounts of untreated waste liquid into sewers, water sources, or soil.
