Applications of Polyethylene Glycol 10000 (PEG-10000, CAS 25322-68-3)

Polyethylene Glycol 10000 (PEG-10000, also listed in major pharmacopeias as Macrogol 10000; CAS 25322-68-3) is a high-molecular-weight, water-soluble polyether supplied as a white flake or powder. The use of PEG-grade polyethers across the application areas described below has been established in the chemical and life-science industries for several decades. Customers are responsible for confirming suitability for their specific formulation and end use.

• Pharmaceutical & Personal Care Excipient

PEG-10000 is recognized as an excipient in USP/NF, EP, and JP under the name Macrogol 10000. It is used by formulators as a water-soluble polymeric ingredient where a high-molecular-weight polyether of consistent quality is called for.

End Products: Pharmaceutical excipient applications, ointment and cream bases, personal care preparations

• Industrial Formulations

PEG-10000 has a long-established role as a water-soluble polymer additive in industrial formulations. End users determine appropriate use levels based on their own qualification and process requirements.

End Products: Metalworking fluid components, ceramic processing aids, textile auxiliaries, water-soluble lubricant blends

• Laboratory & Specialty Chemistry

The reproducible molecular weight distribution and low volatility of PEG-10000 make it a familiar reagent in laboratory and specialty chemistry workflows that require a non-volatile, water-soluble polyether of defined grade.

End Products: Laboratory reagent use, polymer chemistry research, specialty chemical intermediates

Quality & Documentation: Each lot of PEG-10000 is supplied with a Certificate of Analysis confirming the published specification.
