Polyethylene Glycol PEG4000 J6501 Used in the preparation of suppositories and ointments used as a coating agent in the paper industry
Chinese Name: Polyethylene Glycol
English Name: Polyethylene Glycol
CAS No.: 25322-68-3
Molecular Formula: (CH₂CH₂O)_n
Polyethylene glycol exhibits varying properties depending on its relative molecular mass, ranging from colorless, odorless viscous liquids to waxy solids. Those with molecular weights between 200 and 600 are liquid at room temperature, while those above 600 gradually become semi-solid. Properties also differ with changes in average molecular weight. From colorless, odorless

I. Product Overview:
Chinese Name: Polyethylene Glycol
English Name: Polyethylene Glycol
CAS No.: 25322-68-3
Molecular Formula: (CH₂CH₂O)_n
Polyethylene glycol exhibits varying properties depending on its relative molecular mass, ranging from colorless, odorless viscous liquids to waxy solids. Those with molecular weights between 200 and 600 are liquid at room temperature, while those above 600 gradually become semi-solid. Properties also differ with changes in average molecular weight. From colorless, odorless viscous liquids to waxy solids. As molecular weight increases, hygroscopicity correspondingly decreases. This product dissolves in water, ethanol, and many other organic solvents. It has low vapor pressure and is stable to heat, acids, and alkalis. It is inert to many chemicals. It exhibits good hygroscopicity, lubricity, and adhesive properties. Non-toxic and non-irritating.

III. Applications:
PEG-4000 and 6000 serve as excipients in pharmaceutical manufacturing for suppository and ointment preparation; function as coating agents in papermaking to enhance paper gloss and smoothness; act as additives in rubber processing to improve lubricity and plasticity of rubber products, reduce energy consumption during manufacturing, and extend product lifespan.
In pharmaceutical and cosmetic manufacturing, they serve as matrices to regulate viscosity and melting points; in rubber and metal processing, they function as lubricants and coolants; in pesticide and pigment production, they act as dispersants and emulsifiers; in textiles, they are used as antistatic agents and lubricants.
