Polyethylene Glycol 1450 (PEG 1450) is a versatile, water-soluble polymer composed of repeating ethylene glycol units. As a semi-solid to waxy crystalline material, it represents a critical middle-range molecular weight compound in the polyoxyethylene family. Defined by its CAS Registry Number 25322-68-3, PEG 1450 is synthesized through the ring-opening polymerization of ethylene oxide, typically initiated by water or monoethylene glycol under strict temperature and pressure controls.
"The narrow molecular weight distribution of PEG 1450 makes it a fundamental base for pharmaceutical formulations, offering an optimal balance between solvency, consistency, and thermal stability."
For high-tier pharmaceutical, cosmetic, and specialty chemical applications, maintaining rigorous compliance with pharmacopeia monographs (such as USP/NF, EP, and JP) is paramount. Below is the specification breakdown for our premium-grade Polyethylene Glycol 1450:
| Parameter | USP/NF Specification Limit | Typical Analytical Value (YANXA) | Methodology |
|---|---|---|---|
| Appearance | White, waxy solid or flakes | Conforms | Visual Inspection |
| Average Molecular Weight | 1300 - 1600 g/mol | 1450 g/mol | Viscosity Method |
| Hydroxyl Value | 70.0 - 86.0 mg KOH/g | 77.5 mg KOH/g | Titration |
| pH (5% Aqueous Solution) | 4.5 - 7.5 | 6.2 | pH Metry |
| Ethylene Oxide (Residual) | ≤ 10 ppm | ≤ 1 ppm | Headspace Gas Chromatography |
| 1,4-Dioxane (Residual) | ≤ 10 ppm | ≤ 2 ppm | HS-GC-MS |
| Heavy Metals | ≤ 5 ppm | Conforms | ICP-MS |
Due to its non-toxic nature, structural flexibility, and exceptional water solubility, PEG 1450 serves as a critical ingredient across a multitude of regional and global industries.
PEG 1450 acts as a highly effective binder, plasticizer, and lubricant in oral solid dosage forms (tablets and capsules). It facilitates the controlled release of active pharmaceutical ingredients (APIs) and serves as an ointment or suppository base, melting smoothly at body temperature.
In the personal care sector, it is incorporated into creams, lotions, and toothpastes. It functions as a humectant and viscosity modifier, providing structural stability to emulsions while ensuring a smooth, non-greasy feel upon application.
Widely utilized as a mold release agent in rubber manufacturing, a binder in advanced ceramics, and a chemical intermediate in esterification reactions to synthesize surfactants, polyurethane resins, and textile treatment agents.
Sourcing Polyethylene Glycol 1450 from China offers global procurement departments distinct cost-efficiency, scalability, and infrastructure benefits. By partnering with leading petrochemical hubs and leveraging highly automated polymerization facilities, YANXA ensures a steady raw material pipeline that cushions against localized energy shocks and material shortages.
Furthermore, China's advanced logistics networks, centered around primary deepwater ports like Shanghai, Ningbo, and Qingdao, drastically reduce transit times for international bulk shipments. YANXA ensures that all chemical cargo undergoes meticulous inspection, complying with hazardous and non-hazardous shipping regulations to guarantee uninterrupted delivery.
Our commitment to compliance: Every batch is backed by comprehensive documentation, including Certificates of Analysis (CoA), Safety Data Sheets (SDS), and customs compliance paperwork tailored to regional requirements in North America, Europe, and the APAC region.
Procuring chemicals globally requires strict adherence to regional safety and environmental frameworks.
We actively comply with the European Union's Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) standards. Similar compliance files are maintained for TSCA in the US and IECSC in China, ensuring smooth regulatory passage.
To support your local quality assurance departments, we provide complete compliance dossiers: Certificates of Analysis (CoA), GMP compliance status, BSE/TSE-free certificates, GMO-free statements, and allergen profiles.
Understanding that local humidity and temperature variations can affect waxy polymers, we offer custom moisture-barrier packaging. Options include 25kg multi-layer Kraft paper bags with PE inner liners and bulk super sacks.
Cooperating with leading manufacturers and renowned research institutes in China, YANXA supplies high-performance materials for global markets.
