Polyethylene Glycol (PEG)

CAS Number: 25322-68-3
Molecular Formula: H(OCH₂CH₂)nOH
Molecular Weight: Varies depending on molecular weight (e.g., PEG 200 – PEG 20000)

Product Overview

Polyethylene Glycol (PEG) is a versatile, water-soluble polymer widely used in pharmaceuticals, cosmetics, food processing, and industrial applications. It is available in a wide range of molecular weights, from low-viscosity liquids to high-melting solids.

PEG is valued for its excellent lubricity, solubility, non-toxicity, and chemical stability, making it an essential ingredient in formulations requiring moisture retention, dispersion, and surface modification.

Frequently Asked Questions (FAQs)

1. What is the difference between PEG 400 and PEG 6000?

PEG 400 is a liquid with low molecular weight, while PEG 6000 is a solid with higher molecular weight, offering higher viscosity and different application properties.

2. Is Polyethylene Glycol safe for pharmaceutical use?

Yes, pharmaceutical-grade PEG is widely used due to its low toxicity and good biocompatibility, provided it meets regulatory standards.

3. Can PEG be used in cosmetics?

Yes, PEG is commonly used in cosmetics as a moisturizer, emulsifier, and stabilizer.

4. What are the main functions of PEG in formulations?

PEG acts as a solvent, lubricant, dispersant, and humectant, depending on its molecular weight.

5. Is PEG soluble in water?

Yes, PEG is highly soluble in water and many organic solvents, making it very versatile.

6. How do I choose the right PEG grade?

The selection depends on your application:

• Low MW (PEG 200–600): solvents, liquids

• Medium MW (PEG 1000–4000): creams, ointments

• High MW (PEG 6000+): solid formulations, binders
