Polyethylene glycol 4000 and polyethylene glycol 6000 belong to the polyethylene glycol PEG series of products,
which are used in the pharmaceutical industry for suppository, paste preparation;
It is used as finishing agent in the process of papermaking. In the process of rubber processing as an additive,
increase the lubrication and plasticity of rubber products; Used as a substrate in the production of cosmetics industry;
It is used as dispersant and emulsifier in the industrial production of pesticides and pigments.
Used in textile industry as antistatic agent, lubricant, etc.
Polyethylene glycol 4000 referred to as PEG4000, the appearance of milky white solid; It smells slightly foul.
Soluble in water or ethanol, insoluble in ether. Its freezing point is 53~54, and its molecular weight is 3500~4400.
Polyethylene glycol 6000 is referred to as PEG6000, the main chemical composition of ethylene oxide and water condensation polymer,
6000 refers to its average molecular weight of 6000, the range is 5500~7000, the molecular formula is HO(CH2CH2O)nH,
where n represents the average of vinyl oxide. It is a kind of non-toxic, non-irritating, widely used in various pharmaceutical preparations.
