EVIDENCE FROM THE SOURCE!
Newport says their cans contain "oils, waxes, charcoal dust, etc." at less than 50ppm.
I received a follow-up email from Newport/Keen "Near Zero Impurities", Managing Director, Paula Hussain. She states that the cans have 50ppm or less of "oil, wax, charcoal dust etcetera".
However, it is all relative to the amount of BHO that is produced from one can.
From what I know, one can produces around 4grams of BHO.
If each can contains Ms. Hussain's stated ppm of 50, then that leaves .015grams of these "impurities" per 10oz can.
.015 grams of impurities in 4grams of BHO equals 3,750ppm.
IF ALL the impurities are in the end-product, that is high!
Here is her entire response to my question about the 'Mystery Oil'--
"Traditional refineries produced butane propellant with an uncontrolled non-volatile content of impurities including oil, wax substances, charcoal dust etcetera which was not a problem for filling lighters until 1983 when the so-called "flameless" heat-generated turbo lighter was invented in Japan. In order to market this lighter it was established that the non-volatile impurity content of the butane could not exceed fifty parts per one million parts. Our company was assigned this problem which enabled the inventors to market the new product by 1985. Since then numerous diversifications of the concept have appeared. Our exclusive "Near Zero Impurities" has been included on all butane refills that we produce to differentiate our butane refills from all others."
