In fact, gel alcohol is flammable, yes! The difference in relation to liquid alcohol is that, in contact with fire, the gooey version produces a weaker flame, since the composition contains 70% pure alcohol diluted in additives that give it the consistency of a gel. In turn, «liquid alcohol is 95% pure and, therefore, catches fire quickly and evaporates very quickly, making the product less efficient for cleaning than the gel», explains Henrique Eisi Toma, from the Institute of Chemistry at USP . Currently, there are two versions of gel alcohol on the market. The drugstore product – the one that disinfects hands and disappeared from the shelves because of the swine flu – contains ingredients that prevent the skin from drying out – such as triethanolamine – and more pleasant flavorings than those used in cleaning gel alcohol. ;-P
FIRE POWER
The less flammable the alcohol, the more efficient it is at cleaning
ALCOHOL GEL
With only 70% purity in the formula, burning is less intense and evaporation is slower, making this type of alcohol more efficient to disinfect
HYDRATE ALCOHOL
Highly flammable, 95% pure. The other 5% of the solution includes water and a smelly flavoring to prevent people from drinking the product.
ANHYDROUS ALCOHOL
With 100% purity, this alcohol for industrial use is fire for sure. It’s just not good for cleaning, as it evaporates instantly.
