Features Of Polyethylene Glycol PEG600

  1. Water-soluble, non-toxic, and biocompatible polymer with low immunogenicity.

  2. Excellent humectant and plasticizing properties for formulation stability.

  3. High purity grade with consistent molecular weight distribution (target Mn ≈ 600 Da).

  4. Thermally stable up to 150 °C under inert conditions; suitable for melt-processing applications.

  5. Non-volatile, odorless, and colorless liquid at room temperature with low vapor pressure.

Typical Applications Of Polyethylene Glycol PEG600

  1. Pharmaceutical excipient in oral liquid formulations, ointments, and suppository bases.

  2. Carrier and solubilizer for active pharmaceutical ingredients (APIs) in parenteral and topical preparations.

  3. Plasticizer and binder in controlled-release tablet coatings and film-forming systems.

  4. Component in cosmetic formulations including moisturizers, cleansers, and hair conditioners.

  5. Reaction medium and dispersant in polymer synthesis and nanoparticle surface functionalization.
