Polyethylene Glycol 6000 (PEG 6000) is a fascinating polymer with a chemical structure that dictates its diverse and valuable properties. NINGBO INNO PHARMCHEM CO.,LTD. provides this essential chemical, and understanding its scientific underpinnings is key to appreciating its wide-ranging utility.

Chemically, PEG 6000 is a polyether, characterized by repeating ethylene oxide units, with a general formula of HO-(CH2-CH2-O)n-H, where 'n' corresponds to the degree of polymerization that results in an average molecular weight of approximately 6000. This polymeric structure grants it excellent water solubility and hygroscopicity, though these properties tend to decrease with increasing molecular weight.

Its physical state as a white, waxy solid or flakes at room temperature, with a melting point typically between 55-61°C, makes it distinct from lower molecular weight PEGs. The purity, often exceeding 99%, and the CAS number 25322-68-3 are critical identifiers for quality assurance. Key technical specifications, such as its hydroxyl value, viscosity, and a neutral to slightly acidic pH range (4.5-7.5 in solution), are meticulously controlled during production.

The scientific basis for PEG 6000's functionality lies in its ability to act as a binder, lubricant, plasticizer, humectant, and solvent. In pharmaceuticals, these properties are leveraged to improve tablet hardness, ease of ejection, and the stability of topical formulations. Industrially, it serves similar roles in enhancing the properties of textiles, rubber, and paper products. Its low toxicity and biodegradability also contribute to its appeal in environmentally conscious applications.

NINGBO INNO PHARMCHEM CO.,LTD. ensures that the PEG 6000 they supply adheres to rigorous scientific standards, making it a reliable choice for researchers, developers, and manufacturers. By understanding the molecular science behind PEG 6000, industries can continue to innovate and optimize their products and processes.
