Polyethylene Glycol 400 (PEG 400) is a ubiquitous chemical compound with a vast array of applications, from the intricate world of pharmaceuticals to the broad landscape of industrial manufacturing. As a procurement professional or a product formulator, understanding how to effectively source and purchase PEG 400 is crucial for ensuring product quality, operational efficiency, and cost-effectiveness. This guide provides a comprehensive overview of what you need to know when you aim to buy PEG 400.

PEG 400 is a clear, colorless, viscous liquid with a mild odor, and it is highly soluble in water. Its chemical structure, a polymer of ethylene oxide, grants it unique properties that make it exceptionally versatile. In the pharmaceutical sector, it’s widely used as a solvent, humectant, and vehicle in various dosage forms, including oral liquids, topical preparations, and even injectables. Its low toxicity profile and excellent compatibility make it a preferred choice for many drug formulations.

For those in the cosmetics and personal care industry, PEG 400 functions as a moisturizer, lubricant, and emulsifier. It’s commonly found in lotions, creams, hair care products, and soaps, where it improves product texture, skin feel, and hydration. Its ability to enhance the solubility of other ingredients also makes it valuable in complex cosmetic formulations.

In industrial applications, PEG 400 serves as a surfactant, dispersant, and chemical intermediate. It finds use in paints, inks, adhesives, textiles, and metalworking fluids, contributing to improved performance characteristics such as viscosity control, dye dispersion, and lubrication.

When it comes to purchasing PEG 400, several key factors should be considered:

Quality and Purity: Always look for suppliers who provide detailed specifications and Certificates of Analysis (CoA). High purity, often exceeding 99%, is critical, especially for pharmaceutical and cosmetic applications. Ensure the product meets relevant pharmacopeial standards if required.

Supplier Reliability: Partnering with established manufacturers and suppliers is essential for a consistent supply chain. Consider suppliers with strong manufacturing capabilities, robust quality control systems, and a proven track record in the chemical industry.

Pricing and Volume: Prices for PEG 400 can vary based on purity, volume, and supplier. Requesting quotes for bulk purchases from manufacturers, particularly those in China, can often lead to more competitive pricing. It’s important to balance cost with quality and service.

Regulatory Compliance: Verify that the supplier can provide necessary documentation for regulatory compliance in your target markets, including MSDS and any required certifications.

By carefully evaluating these aspects, you can confidently select a supplier that meets your needs. Purchasing PEG 400 from a trusted source ensures that you receive a high-quality product that will contribute to the success of your formulations and manufacturing processes.
