Everyday+Use

Antiseptics:Ethanol can be used as an antiseptic to disinfect the skin before injections. Alcohol based gels have become common hand sanitizers used in restaurants.
=== Fuels: Some alcohols, mostly ethanol and methanol, can be used as an "Alcohol fuel". Fuel performance can be increased by injecting alcohol into the air to cool the pressurized air, providing a denser air charge, which allows for more fuel, and therefore more power. ===

Preservative: Alcohol is often used as a preservative ( a naturally occurring or synthetically produced substance that is added to products) in the fields of science and medicine.
=== Solvents: Hydroxyl groups (-OH), found in alcohols, are polar and therefore hydrophilic, but their carbon chain is non-polar which makes it hydrophobic. The molecule increasingly becomes overall more non-polar and therefore less soluble in water as the carbon chain becomes longer. ===
