Polyethylene Glycol 400 – PEG 400 1 Quart
This PEG 400 variant is a general-use solvent and humectant suitable for multiple formulations. Best for small-scale projects, basic lab tasks, and cosmetic prep where moderate purity suffices. Limitation: may not be NF-grade or meet stricter pharmaceutical specifications for sensitive applications.
Polyethylene Glycol 400 – PEG 400 1 Gallon
Designed for bulk usage, this PEG 400 option supports larger formulation batches and industrial applications. Best for laboratories and manufacturers needing a steady supply for ongoing projects. Caution: ensure container integrity for long-term storage to avoid contamination or moisture uptake.
Carbowax (Polyethylene Glycol) PEG 400 (NF) (1 L)
This product is labeled NF, indicating National Formulary compliance, making it a solid choice for more precise formulations and regulated environments. Best for pharmaceutical-grade processes where NF certification adds value. Limitations: price and availability may vary; NF-grade materials can have tighter handling requirements.
Polyethylene Glycol 400 (PEG 400) Superior High-Purity, 500mL
High-purity PEG 400 suitable for industrial and laboratory needs. Best for formulators requiring consistent quality across multiple batches. Choose this if you need a smaller, high-purity bottle for ongoing experiments. Limitation: smaller package size may require more frequent reordering for large projects.
Lab Alley PEG 400 Food Grade (FCC, USP), 1 Gallon
Food-grade PEG 400 with FCC and USP alignment, Halal certified, and suitable for cosmetic, food, pharmaceutical, and industrial uses. Best for applications needing food-safe and cosmetic-safe materials. Caution: verify that the specific batch meets your regulatory requirements for your product line.
Buying Guide
What grade do you need?
NF (National Formulary) or USP/FCC grades are essential for regulated pharmaceutical, cosmetic, or food applications. If strict regulatory compliance matters, prioritize NF or USP/FCC-certified PEG 400.
What package size fits your workflow?
For pilots or small projects, 500 mL to 1 L bottles reduce waste and storage risk. For ongoing or large-scale production, 1 gallon or larger containers improve continuity and reduce reordering frequency.
What purity and certifications are required?
Cosmetic and food products benefit from Halal certification and USP/FCC compliance. Industrial users may accept broader purity, but NF/USP ensures tighter quality control.
Storage and handling considerations
Store PEG 400 in a cool, dry place away from moisture sources. Use proper containers to minimize moisture uptake, which can affect viscosity and purity over time.
Safety and compatibility
PEG 400 is generally considered safe for various formulations when used as directed. Check compatibility with other solvents, actives, and packaging materials to avoid adverse interactions.
