What are the physicochemical technical parameters of polyethylene glycol PEG-200?

Physicochemical Technical Parameters of Polyethylene Glycol PEG-200 - Based on Guoli Chemical Product Database

Detailed Description

Polyethylene glycol 200 (PEG-200) is a typical non-ionic surfactant, appearing as a colorless, transparent, viscous liquid. Its chemical name is α-hydro-ω-hydroxypoly(oxy-1,2-ethanediyl), with CAS number 25322-68-3. This product exhibits excellent chemical inertness and multifunctionality, outstanding chemical stability, resistance to acids, alkalis, and hard water, and does not react with most chemicals under a wide range of working conditions.

According to the Guoli Chemical product database, PEG-200 has high toxicological safety and is classified as a low-toxicity substance: acute oral toxicity LD50 >2000 mg/kg (rat), no or only very slight skin irritation, slight eye irritation, no skin sensitization, and no genotoxicity. Ecologically, the product has low ecotoxicity, is readily biodegradable, and is not expected to bioaccumulate.

Please note: The Guoli Chemical product database does not provide a detailed table of physicochemical numerical parameters for PEG-200 (such as specific values for density, viscosity, pH value, hydroxyl value, molecular weight, etc.). The following are general industry reference parameters for polyethylene glycol 200 for your reference. Specific batch data should be based on the Certificate of Analysis (COA) issued by Guoli Chemical.

Application Suggestions

Based on PEG-200's moderate molecular weight and excellent solubility, the following application scenarios are recommended:

• Personal Care: Used as a humectant and lubricant in shampoos, body washes, creams, and toothpaste, providing a smooth skin feel. Recommended addition amount: 1%~5%.
• Pharmaceutical Industry: Acts as an ointment base and drug solubilizer, effectively enhancing the bioavailability of active ingredients.
• Agrochemical Formulations: Serves as an emulsifying and dispersing agent to help uniformly disperse active pesticide ingredients, improving efficacy.
• Industrial Casting: Used as a key component in mold release agents and as a heat transfer fluid, providing excellent high-temperature lubricity.
• Chemical Synthesis: Acts as an ethoxylation intermediate, participating in esterification, etherification, and other reactions to produce specialty surfactants and plasticizers.

Precautions

• Recommended storage temperature: 15°C to 30°C. Keep container tightly sealed to prevent moisture absorption.
• It is recommended to wear safety goggles and protective gloves during operation. Use in a well-ventilated area.
• Avoid contact with incompatible substances such as strong acids and strong oxidizers.
• Storage containers should be made of stainless steel, polyethylene, or epoxy-lined carbon steel.
• In case of accidental eye contact, rinse immediately with plenty of water for at least 15 minutes and seek medical attention if necessary.
• Although the product is low-toxicity and mild, good industrial hygiene practices should still be followed during handling.
