  • What is polyethylene glycol 8000?
  • Polyethylene glycol 8000 (CAS No. 25322-68-3) is a Polyethylene glycol having white to off white color and available in solid flakes or powder form. Its high molecular weight mainly prompts its use in pharmaceutical formulations as solvent for oral, topical and parenteral preparations.
  • What is polyethylene glycol 6000?
  • Polyethylene glycol 6000 (CAS No. 25322-68-3) is a derivative of Polyethylene glycol having white to off white color and available in solid flakes or powder form. The melting range for Polyethylene glycol 6000 is between 58-63 oC and the average molecular weight can be within 5000-7000.
  • How many polyethylene glycol derivatives are there?
  • A total of 12 polyethylene glycols derivatives were chosen to be investigated based on their average molecular weight. Range of molecular weight is also indicated. PEG 200 (190–210 MW), PEG 300 (290–305 MW), and PEG 600 (550–650 MW) were obtained from TCI (Zwijndrecht, Belgium).
  • What is polyethylene glycol 4000?
  • Polyethylene glycol 4000 (commonly refered to as Polyethylene glycol 4000) typically exists as white to off white flaky solid with a hydroxyl number of 28-36 mg KOH/g and approx. mol weight of 3100-4010. The solubility of a 5% solution is clear and colourless.
