Polyethylene Glycol 4000: A Versatile Pharmaceutical Intermediate

Discover the extensive applications and chemical properties of PEG 4000, a key component in various industries.

Product Core Value

Polyethylene Glycol 4000

Polyethylene Glycol 4000 (PEG 4000) is a crucial chemical compound with the CAS number 25322-68-3, widely recognized for its utility as a mollifier and its extensive applications across pharmaceutical and industrial sectors.

Explore the polyethylene glycol 4000 uses in detailed formulations. Its molecular weight between 700 and 900 is a semi-solid, while 1000 and above presents as light white waxy solid, flake paraffin, or liquid powder.
Understand the PEG 4000 pharmaceutical applications for advanced medical treatments. It is soluble in water and many organic solvents, yet insoluble in most aliphatic hydrocarbons and ethers.
Learn about the CAS 25322-68-3 chemical properties vital for industrial processes. With increasing molecular weight, water solubility and vapor pressure decrease, while freezing point and viscosity increase.
Discover why polyethylene glycol for mollifier is a preferred choice. Its non-toxic and colloidal nature makes it suitable for various consumer products and industrial agents.

Key Advantages of Polyethylene Glycol 4000

Sustained Drug Release

Leverage drug sustained-release carrier capabilities of PEG 4000, enabling controlled diffusion of active ingredients to enhance therapeutic efficacy.

Moisturizing and Lubricating Properties

As a humectant, PEG 4000 effectively locks in moisture, making it ideal for topical formulations like creams and ointments, often found in cosmetic raw material applications.

Osmotic Laxative Functionality

The effectiveness of osmotic laxative PEG 4000 lies in its ability to increase osmotic pressure in the intestinal cavity, softening stool and promoting regular bowel movements.

Key Applications

Pharmaceutical Formulations

PEG 4000 is a cornerstone in polyethylene glycol 4000 uses, acting as an excipient in tablets, ointments, suppositories, and controlled-release drug delivery systems.
