Dow CARBOWAX PEG 3350 Polyethylene Glycol – Frequently Asked Questions (FAQ)

Q1: What is the primary functional role of CARBOWAX PEG 3350 in pharmaceutical and personal care formulations?

A: CARBOWAX PEG 3350 serves primarily as a water-soluble binder, solubilizer, and viscosity modifier. It enhances the dissolution rate of active ingredients, improves tablet disintegration, and contributes to uniform dispersion in liquid and semi-solid systems such as ointments, gels, and oral suspensions.

Q2: How does CARBOWAX PEG 3350 differ from lower- or higher-molecular-weight PEG grades in terms of physical behavior?

A: With an average molecular weight of approximately 3350 Da, CARBOWAX PEG 3350 is a semi-crystalline, low-melting solid at room temperature—offering a favorable balance between solubility, melt processability, and film-forming capability. It melts more readily than higher-MW PEGs (e.g., PEG 6000) and provides greater viscosity and binding strength than lower-MW grades (e.g., PEG 400 or PEG 1000).

Q3: Is CARBOWAX PEG 3350 suitable for use in hot-melt extrusion (HME) processes?

A: Yes—it is commonly selected for HME applications due to its relatively low melting point (~52–57 °C), thermal stability under typical processing conditions, and ability to act as both a plasticizer and matrix former. Its compatibility with APIs and polymers supports robust amorphous solid dispersion formation.

Q4: Can CARBOWAX PEG 3350 be used in food-contact or pharmaceutical-grade applications?

A: Dow manufactures CARBOWAX PEG 3350 to meet USP/NF and Ph. Eur. monograph requirements for Polyethylene Glycol 3350, supporting its use in pharmaceutical dosage forms and certain food-contact applications where regulatory compliance and quality consistency are required. Always verify conformance with current lot-specific documentation.
