Polyethylene glycol 9000

Polyethylene glycol 9000 is a polyether compound derived from petroleum with many applications, from industrial manufacturing to medicine. 
Polyethylene glycol 9000 acts as a binder and filler offering internal and external lubrication.  

Polyethylene glycol 9000 is also known as PEG 9000, polyethylene oxide (PEO), or polyoxyethylene (POE), depending on its molecular weight

Polyethylene glycol 9000 
Cas No: 25322-68-3

Polyethylene glycol 9000 is used as a stabilizing agent for fragrance in the fabric care market and as a binder for solid particle delivery.

Polyethylene glycol 9000, also called PEG 9000 or Macrogol in the European pharmaceutical industry, is manufactured by polymerization of ethylene oxide (EO) with either water, mono ethylene glycol or diethylene glycol as starting material, under alkaline catalysis. 

Storage of Polyethylene glycol 9000
When stored in a cold, dry place in a closed container Polyglykol 9000 can be kept for at least two years. 

Applications of Polyethylene glycol 9000
Based on its physical and chemical characteristics -polyethylene glycol 9000 is used for a wide variety of applications. 

Fields of application: 
- Reactive diol/polyether components in polyester or polyurethane resins
- Component of auxiliaries for leather and textile processing
- Cosmetic/pharmaceutical formulations (e.g. humectant or plasticizer for creams, tablets, toothpaste)
- Lubricant and mold release agent for rubber, plastic, and elastomer processing
- Plasticizer and binder for ceramic and concrete manufacturing
