Product: Polyethylene Glycol (PEG)
Rchem Polyethylene Glycol (PEG) is a versatile, water-soluble, non-ionic polymer available in a wide range of molecular weights, from low-viscosity liquids to waxy solids. This polyether compound is renowned for its excellent solubility, low toxicity, and broad compatibility, making it a fundamental ingredient across the pharmaceutical, cosmetic, personal care, and industrial sectors. Its ability to act as a humectant, plasticizer, solvent, and base makes it an indispensable tool for formulators.

Frequently Asked Questions:
How do I choose the right PEG grade for my application?
The choice depends on the desired physical properties: Liquids (PEG 200 - 600): Used as solvents, carriers, and humectants in liquids and low-viscosity products. Semi-Solids (PEG 1000 - 1450): Used in ointments and creams for their spreading properties. Solids (PEG 3350 - 20,000): Used as binders in tablets, as bases for suppositories, and as thickeners in solid formulations. PEG 3350 is a common osmotic laxative.
Yes, PEGs are extensively used and considered safe for topical, oral, and mucosal application in both cosmetics and pharmaceuticals. They have a long history of safe use and are approved by regulatory bodies worldwide.
Is PEG safe for use in cosmetics and pharmaceuticals?
While both are polyethers, PEG is hydrophilic (water-soluble) and often used for its solubility and humectant properties. PPG is more hydrophobic (water-insoluble) and is typically used as a lubricant, surfactant, or in polyurethane foams.
What is the difference between PEG and PPG (Polypropylene Glycol)?
Lower molecular weight PEGs are not typically used as primary emulsifiers on their own. However, they are often components of non-ionic emulsifying systems (e.g., PEG-100 Stearate) where the PEG portion provides hydrophilicity. Higher MW PEGs can help stabilize emulsions by increasing the viscosity of the aqueous phase.
Can PEG be used as a primary emulsifier?
Some concerns relate to potential contamination with impurities like ethylene oxide and 1,4-dioxane, which are processing by-products. Rchem ensures our PEGs comply with strict pharmacopeial standards (USP, Ph. Eur.), which set tight limits for these impurities, guaranteeing a high-purity and safe product for our customers.
