Description
Solid Polyethylene Glycol (PEG)
$H–(O–CH_{2}–CH_{2})_{n}–OH$ | Hydrophilic & Biocompatible Polyether | Grades 1000 to 20000 | Supplier: MizanPetroGas
Product Introduction
Polyethylene Glycol, abbreviated as PEG, is a linear synthetic polyether with the general formula $H–(O–CH_{2}–CH_{2})_{n}–OH$. Produced through the ring-opening polymerization of ethylene oxide (EO) using an alkaline catalyst, it is categorized depending on its molecular weight (number of repeating units $n$) into liquid (grades 200 to 600) and solid (grades 1000 to 20000) forms.
Solid Polyethylene Glycol (Solid PEG) presents as a waxy, white to off-white material supplied in forms such as flakes, fine powder, or granules. Fully hydrophilic and biocompatible, this substance boasts extremely low volatility and favorable thermal stability up to approximately 300°C, securing an essential position across the pharmaceutical, cosmetic, detergent, tile & ceramic, textile, and adhesive industries.
MizanPetroGas Company supplies all solid PEG grades — from PEG-1000 to PEG-20000 — meeting the highest quality standards (USP/BP/EP) and packaged in standard industrial drums to manufacturers worldwide.

Pricing and Purchasing Solid Polyethylene Glycol (Solid PEG)
The price of solid PEG varies based on molecular weight (selected grade), purity (pharmaceutical grade USP vs. industrial grade), order volume, packaging type, and global ethylene oxide price fluctuations. Sourcing directly without intermediaries from top domestic and international manufacturers, MizanPetroGas enables industrial clients to request real-time pricing, receive free samples, and place orders in any required tonnage.

Key Features and Highlights
🔹 Extremely Low Volatility
Under ambient and standard operational conditions, solid PEG exhibits virtually no evaporation or mass loss. This characteristic ensures that the material remains stable throughout the manufacturing process, storage, and end application, maximizing the economic yield of formulations. An insignificant vapor pressure (< 0.001 kPa at 20°C) means zero VOC emissions and full environmental compliance.
🔹 Favorable Thermal Stability
This valuable polyether can maintain its chemical structure and thermal stability for limited periods at temperatures below 300°C. This property is vital in heat-dependent industrial processes — such as ceramic glaze firing, hot-melt extrusion, injection molding, and polymer processing — offering a wide operational window for process engineers.
🔹 Complete and Rapid Water Solubility
Due to the presence of ether linkages (–O–) and terminal hydroxyl groups (–OH) at both ends of the polymer chain, solid PEG forms strong hydrogen bonds with water. This enables complete, rapid, and exothermic dissolution in water at ambient temperatures or with mild heating — without needing intermediate organic solvents or co-solvents.
🔹 Full Biocompatibility and Non-Toxicity
Solid Polyethylene Glycol is recognized as one of the safest and most biocompatible synthetic polymers. It holds FDA approvals (GRAS) and meets USP/BP/EP pharmacopeial monographs for pharmaceutical and cosmetic applications. Being non-irritating, non-sensitizing, and non-mutagenic, it is suitable for products coming into direct contact with skin, mucous membranes, or for oral pharmaceutical administration.

Safety and Storage
- ⚠️ Moisture — Primary Concern: Solid Polyethylene Glycol is highly hygroscopic. Containers must be tightly sealed immediately after use. Storage in environments with relative humidity below 60% is recommended.
- Storage Temperature: 5–35°C — keep away from heat sources, direct sunlight, and radiators. Repeated melting and freezing cycles may cause changes in crystalline structure and caking.
- Ventilation: Ensure adequate warehouse ventilation. Although PEG is non-volatile, accidental thermal degradation (above 300°C) may release aldehyde gases and carbon monoxide.
- Personal Protective Equipment (PPE): Despite being non-toxic, the use of gloves, dust masks (N95), and safety goggles is recommended when handling powdered forms (respirable fine particles).
- Incompatibilities: Avoid contact with strong oxidizers (peroxides, nitrates, permanganates) and concentrated acids to prevent oxidative polymer chain degradation.
- First Aid: Eye/Skin Contact ← Flush with abundant water for 15 minutes. Ingestion ← Drink plenty of water; medical intervention is generally unnecessary (non-toxic), but consult a doctor if gastrointestinal discomfort occurs.
- Firefighting: Water fog, $CO_{2}$, dry chemical powder, alcohol-resistant foam — molten hot PEG contacting cold water may cause splattering; handle with care.
