    Hello:

    It is not often people write emails or letters of praise but consider this one of the rare ones!
    I must say, ordering your product was about the easiest imaginable. Coupled with the fact that it arrived here basically “next day” I am thoroughly happy. To tell you the truth, I was expecting to have to go pay full retail for one black cartridge thinking that your’s would take at least a week to arrive but I was wrong, the order arrived before I could even go out to get one!
    Congrats people, I WILL tell all my friends and neighbours about you!

Inkjet Ink Secret Ingredient

Posted on February 24, 2010 by kflack

N-Methyl-2-pyrrolidone

Also goes by the name (Chemists call it) N-Pyrol.

This ingredient can make up to 40-60% of some inkjet inks and is the secret ingredient that prevents the ink from evaporating into the air.

Beware though. There are many refill establishments that do not use N-Pyrol in their inks (Typically drop by and refill shops) where the ink may need to be used within 30 days after refilling. Inkjet cartridges using N-Pyrol can last 3 years and more without any degradation in the effectiveness of the ink when used in the 20 deg C range.

Considered a “fairly” non toxic ingredient, it is also commonly used for Paint Strippers.

It is readily absorbed by the skin and has been know to cause local irritation in laboratory testing.

You can find a MDS (Data Safety) sheet at this link.

or the International Chemical Safety card sponsored by the National Institute for Occupational Safety and Health
