Isopropyl Alcohol / IPA
Isopropyl alcohol, commonly referred to as IPA or Propan-2-ol, is a flammable, clear, colourless liquid with a slightly pleasant alcoholic odour. It possesses physical,chemical and solvency properties similar to those of ethyl alcohol, making it completely miscible with water and soluble in most organic solvents. Isopropyl Alcohol is a highly versatile solvent which has 1001 uses. Second only to water it is the most commonly used liquid for cleaning and is found in millions of products world wide. It is used in manufacturing acetone, glycerol and isopropyl acetate. A solvent for many oils, alkaloids, gums and resins, it also serves as a deicing agent for liquid fuels. The chemical compound is used in extraction processes, as a dehydrating agent and as a laboratory reagent.
Uses for Isopropyl alcohol
Isopropyl alcohol is registered as an adjuvant, used to facilitate pesticide applications in agricultural settings, and as an adjuvant in industrial water washer, cooler, and condenser systems.

Using Isopropyl Alcohol to prevent water from freezing:
- 10% alcohol:90% water will reduce the freezing point of water from 0 deg C to -3 deg C.
- 20% alcohol:80% water will reduce the freezing point of water from 0 deg C to -7 deg C.
- 40% alcohol:60% water will reduce the freezing point of water from 0 deg C to -20 deg C
At these sorts of mixes water will not freeze at its normal 0 Deg C.
