82% Ethanol
9% Isopropanol
2% Methanol
1% Methyl Isobutyl Ketone


Rubbing Alcohol:
The systematic name for isopropyl alcohol is propan-2-ol
The structure is CH3-CH(OH)-CH3
It is called rubbing alcohol becuase it is definitely not for
drinking! Propan-2-ol is commonly used in disinfectant swabs used
to clean skin before an injection, and many people recognise it from
this.


Methylated spirit:
is an even nastier mixture of ethanol, methanol,
blue dye and pyridine (ugh).
"Industrial methylated spirit" (IMS) is 90% ethanol, 5% methanol, 5%
water.
