Product Description


CAS 9004-74-4 Methxypolyethylene Glycol MPEG-350 MPEG-500 MPEG-750 m-PEG-OH (MW 2000)


Product Description

Methxypolyethylene Glycol (MPEG) Description

Methxypolyethylene Glycol (MPEG) is a chemical compound derived from polyethylene glycol (PEG) with a methxy group at one end of the polymer chain. It is a nonionic, water-soluble polymer with excellent biocompatibility, low toxicity, and versatility due to its chemical structure. MPEG is widely used in various industries, including pharmaceuticals, cosmetics, and industrial applications, as a thickening agent, dispersant, or surfactant.

Key Features

  1. Water Solubility: Highly soluble in water and many organic solvents.
  2. Biocompatibility: Low toxicity and non-immunogenic, making it suitable for pharmaceutical and cosmetic applications.
  3. Thermal Stability: Stable under a wide temperature range.
  4. Chemical Reactivity: The terminal methxy group can be modified for functionalization.
  5. Nonionic Nature: Compatible with ionic and nonionic systems.
  6. Film-Forming Ability: Useful in coating and encapsulation applications.
  7. Lubrication Properties: Offers smoothness and reduces friction in formulations.


Applications

1. Pharmaceuticals

  • Drug Delivery: Used in the formulation of controlled-release drugs and PEGylation of biopharmaceuticals to improve solubility and stability.
  • Hydrogels: As a component in hydrogel-based drug delivery systems.

2. Cosmetics and Personal Care

  • Moisturizers and Emollients: Acts as a humectant and skin-conditioning agent.
  • Surfactant: Enhances the stability and texture of formulations (e.g., creams, lotions).

3. Industrial Applications

  • Polymer Additive: Used as a plasticizer, lubricant, or dispersant in polymer processing.
  • Textiles: Acts as an anti-static agent and lubricant for fibers.
  • Adhesives and Coatings: Improves adhesion, flexibility, and durability of coatings.

4. Food Industry

  • Food Additive: Acts as a stabilizer, thickener, or emulsifier in food products.

5. Agriculture

  • Fertilizers and Pesticides: Used as a dispersant and solubilizer for active ingredients.
