Default Tetenal Protectan Composition

I have just purchased a tin of Tetenal Protectan.
It is used to squirt into bottles of developer etc. to stop them going off.
After reading a few posts on people using cans of lighter refill gas, and some people saying how dangerous this could be, I purchased the real thing. TETENAL PROTECTAN.
The first thing that I read when I looked at the can was a serious warning printed on the aerosol about the dangers of using near naked flames, and cans exploding in excessive heat
The link below takes you to the TETENAL DATA SHEET FOR PROTECTAN.....…….
On page 2 it gives the ingredients.
BUTANE...……...50-70%
PROPANE..……..20-30%
ISOBUTANE.....10-20%

So watch your step when using it.
