This guide aims to clarify the distinctions and highlight the importance of selecting the right PEG grade.

Polyethylene Glycol 4000 (PEG 4000) is most recognized for its pharmaceutical applications. As a pharmaceutical excipient, it adheres to stringent quality standards, including compliance with USP, EP, and CP. This ensures its safety and efficacy when used in tablets as a binder, in ointments as a base, or in various oral and topical formulations. The pharmaceutical grade is characterized by high purity, low impurity levels, and consistent physical properties, making it ideal for therapeutic uses. When you choose to buy PEG 4000 excipient from NINGBO INNO PHARMCHEM CO.,LTD., you are assured of these critical quality attributes.

Beyond pharmaceuticals, PEG 4000 also serves in cosmetic formulations. Here, its properties as a humectant and emollient are highly valued, contributing to skin hydration and a pleasant feel in creams, lotions, and other personal care products. While technical grades of PEG exist for broader industrial applications such as lubricants and solvents, the choice of pharmaceutical or cosmetic grade underscores a commitment to purity and safety. The industrial uses of polyethylene glycol are vast, but for sensitive applications, grade selection is paramount.

The availability of different molecular weights, such as PEG 4000, 6000, or 8000, dictates specific physical properties like melting point and viscosity. PEG 4000, being a solid flake or powder, offers different handling and formulation advantages compared to liquid PEGs. NINGBO INNO PHARMCHEM CO.,LTD. offers a range of PEG products, ensuring that clients can find the precise specifications needed for their formulations. Understanding the polyethylene glycol price in relation to grade and molecular weight is part of making an informed purchasing decision.
