Polyethylene Glycol/ PEG-200/ PEG-400 600 4000 6000 8000 CAS 25322-68-3

 

 

Description:

  • Chemical Formula: (C2H4O)n, where n represents the average number of ethylene oxide units in the polymer chain.
  • Molecular Weight: The average molecular weight of PEG-400 is approximately 400 g/mol.
  • Structure: PEG-400 is a clear, viscous liquid at room temperature. It is a water-soluble compound and has a relatively low vapor pressure.

Specification:

  • Purity: PEG-400 is commercially available in various purity grades, typically ranging from 99% to higher levels. The specific purity may depend on the manufacturer and intended application.
  • Viscosity: The viscosity of PEG-400 is relatively high, given its molecular weight. The viscosity may vary depending on the temperature.

Application:

  1. Pharmaceutical and Medical Applications: PEG-400 finds extensive use in the pharmaceutical and medical industries. It is commonly employed as a solvent, carrier, or excipient in various formulations, including oral medications, topical creams, ointments, and suppositories. PEG-400 can enhance the solubility and bioavailability of poorly soluble drugs. It also acts as a lubricant and moisture-retaining agent in certain medical devices and eye drops.

  2. Industrial Applications: PEG-400 is utilized in several industrial applications due to its unique properties. It serves as a plasticizer, binder, and lubricant in the production of adhesives, resins, and coatings. PEG-400 also functions as a humectant and moisture regulator in personal care products, such as lotions, creams, and cosmetics.

  3. Chemical Reagent and Catalyst: PEG-400 can be used as a reagent or catalyst in various chemical reactions. It is sometimes employed as a reaction medium or solvent for organic synthesis. Its high boiling point and low volatility make it suitable for high-temperature reactions and processes.

Features:

  • Solubility: PEG-400 is highly soluble in water and many organic solvents, which contributes to its versatility as a solvent or carrier for various substances.

  • Low Toxicity: PEG-400 is considered to have low toxicity and is generally well-tolerated. It is widely used in pharmaceutical and personal care applications due to its favorable safety profile.

  • Hygroscopic Nature: PEG-400 is hygroscopic, meaning it readily absorbs moisture from the environment. This property can be advantageous in formulations where moisture retention or prevention of drying out is desired.

  • Stability: PEG-400 exhibits good stability under normal storage and handling conditions. It is resistant to microbial growth and degradation.

  • Biocompatibility: PEG-400 is known for its biocompatibility, meaning it is well-tolerated by living tissues and has minimal adverse effects. This characteristic is important in pharmaceutical and medical applications.

  • Non-ionic: PEG-400 is a non-ionic compound, meaning it does not carry an electrical charge. This property can be beneficial in certain formulations, such as those requiring a non-ionic surfactant or excipient.

 

Description:
Polyethylene glycol (PEG) is a water-soluble, odorless, and colorless polymer. It is formed by the polymerization of ethylene oxide, resulting in a range of molecular weights. PEG is available in liquid or solid form, depending on the molecular weight.

Specifications:
The specifications of PEG can vary based on the desired molecular weight and application. The molecular weight of PEG typically ranges from a few hundred to several thousand. Different grades of PEG are available, including PEG 200, PEG 400, PEG 600, PEG 1000, PEG 1500, PEG 4000, and so on.

Application:

  1. Pharmaceuticals: PEG is commonly used in pharmaceutical formulations as a solubilizing agent, excipient, or vehicle for drug delivery. It enhances the solubility, stability, and bioavailability of poorly soluble drugs.
  2. Cosmetics: PEG is used in cosmetics and personal care products as a thickening agent, emulsifier, or humectant. It helps to improve the texture, spreadability, and moisturizing properties of creams, lotions, and ointments.
  3. Industrial Applications: PEG is employed in various industrial processes such as lubricants, antistatic agents, plasticizers, and as a dispersant in ceramics and paints.
  4. Food Industry: PEG is used as a food additive, primarily as a thickening agent, stabilizer, or moisture-retaining agent. It can be found in products like ice cream, baked goods, and processed meats.

Features:

  1. Solubility: PEG is highly soluble in water and many organic solvents, which makes it easy to incorporate into various formulations.
  2. Non-toxic: PEG is generally considered safe and non-toxic for most applications. However, specific grades and molecular weights should be used based on the intended use.
  3. Hygroscopic: PEG has hygroscopic properties, meaning it can attract and retain moisture, which makes it useful in products requiring moisture control.
  4. Compatibility: PEG is compatible with a wide range of other substances, including active pharmaceutical ingredients (APIs), excipients, and cosmetic ingredients. It can be easily blended with other materials.
  5. Stability: PEG is stable under normal storage conditions and does not undergo significant degradation or decomposition.
