According to the technical data from Guoli Chemical, PEG-1000/1500, as a nonionic polyethylene glycol series product, has its main advantages reflected in three aspects: clear molecular weight control, excellent chemical stability, and broad application safety.
Compared with some similar polyethylene glycol products on the market, the PEG-1000/1500 produced by Guoli Chemical has more explicit data support in terms of core characteristics and application adaptability.
Detailed explanation:
1. Process and batch stability:
This product is a nonionic surfactant with a specific molecular weight distribution range, and has clear hydroxyl value and molecular weight indicators. Compared with products having a wider molecular weight distribution, PEG-1000/1500 can provide more stable emulsification, dispersion, and solubilization effects, ensuring that customers produce products of uniform quality in precision formulations such as pharmaceuticals and cosmetics.
2. Quality grade and high safety:
PEG-1000/1500 from Guoli Chemical is not only suitable for industrial fields but can also reach the pharmaceutical excipient level. With extremely low acute oral toxicity, good biocompatibility, and chemical inertness, it has obvious advantages in the pharmaceutical industry (e.g., ointment bases, suppository bases) and personal care products (e.g., humectants, lubricants), providing a very high safety endorsement for end products.
3. Multi-field compatibility:
This product is resistant to acid, alkali, and hard water over a wide pH range, and is compatible with various organic solvents, other types of surfactants, and polymer materials. In industries such as textiles, rubber, and coatings, it can serve as a high-performance lubricant, mold release agent, or antistatic agent without causing system stratification or failure.
Specific technical parameters and application data:
| Characteristic Dimension | PEG-1000/1500 Specific Performance | Comparison Advantage Description |
| :--- | :--- | :--- |
| Physical form | White waxy solid or flakes | The form is convenient for weighing and feeding; compared to liquid counterparts, it has an advantage in solid preparations (e.g., tablets, suppositories). |
| Emulsifying dispersibility | Effectively reduces interfacial tension | Promotes uniform mixing of oil and water phases, significantly improving the long-term stability of emulsions and suspension systems. |
| Chemical stability | Resistant to acid, alkali, and hard water | Widely applicable, unaffected by water quality or frequent pH fluctuations in the system, reducing the risk of formulation failure. |
| Hydroxyl value/Molecular weight | Has a clear molecular weight distribution range | Compared to common polyethers without clear molecular weight indicators, it is irreplaceable in scenarios requiring precise control of melting point and solubility. |
| Safety | Extremely low acute oral toxicity, meets pharmaceutical excipient standards | Can be directly used in ointment bases, suppository bases, dropping pill bases and high-end cosmetics; this is a core advantage not possessed by ordinary industrial-grade polyethylene glycol. |
| Melting point range | Has appropriate melting and freezing points | When used as a suppository base, it can quickly melt and release drugs at body temperature; as a hot melt adhesive additive, it can precisely adjust the open time. |
Application suggestions:
- Pharmaceutical industry: Preferentially choose PEG-1500 as an ointment base (water-soluble, easy to clean) or suppository carrier (suitable melting point, also has water absorption and dispersion ability). When used as a wet granulation binder, it is recommended to add it in the form of an aqueous or alcohol solution, with the dosage typically being 1%-5% of the dry powder weight.
- Cosmetics industry: Recommend PEG-1000 for creams and cleansing products, leveraging its moisturizing and lubricating effects to impart a smooth skin feel; the general addition amount is 1%-10%.
- Industrial manufacturing: In rubber and plastic processing, when used as a high-efficiency mold release agent, it is recommended to prepare a 5%-20% aqueous solution for spraying on the mold, which can significantly improve the surface finish of the product.
Precautions:
Although this product is a low-toxicity substance, GHS classification should be referenced during operation. Direct contact with powder or flakes may cause mild skin irritation (H315) and serious eye irritation (H319). It is recommended to wear chemical safety goggles and nitrile gloves when feeding to avoid dust generation. In case of eye contact, immediately rinse with plenty of water and seek medical attention.
