Subject: Shelf Life of PEG 400 used for Phenol First Aid Treatment

We're developing first aid procedures for phenol and phenol/chloroform.  
This involves decontaminating affected areas with polyethylene glycol 
(400 MW) instead of water.  Flushing with water may spread phenol to 
other parts of the body.

Because of its expense, we plan to buy larger quantities of PEG 400 and 
repackage it into 1 L nalgene bottles.  This, along with other supplies 
(gauze pads, gloves, disposable coveralls - for modesty, etc.) will be 
put in light tight buckets.  The buckets will be stored in labs at room 

My question is about the shelf life of the PEG after it has been opened 
and repackaged.  Chemical suppliers report shelf lives from 1 to 2 
years.  But I believe this applies to PEG intended for manufacturing and 
research applications. 

Does anyone have experience with the use of PEG 400 for 1st aid 
treatment who can recommend a shelf life?  Literature citations (if they 
exist) would be much appreciated.
