What is ethanol? Ethanol is a clear colourless liquid that can be made from many different sources including wheat, molasses a by-product of sugarcane production or any starch. It is also known as alcohol The boiling point of ethanol is 78 °C and the flashpoint is 11 °C. There are many ethanol products on the market in Australia that are not manufactured for drinking or human consumption. These include for the extraction of essential oils, disinfectants, sterilisation medical equipment, as a window cleaner, automotive fuel and octane booster and there are many more uses including indoor or outdoor ethanol heating. Drinking grade ethanol or alcohol differs from commercial or industrial grades with no addition of denaturants, Bitrex, hydrocarbon or methanol. Denaturants are added the ethanol to stop people drinking the product. Whisky (#whiskeyneatnopeat), vodka, rum and brandy are all alcohols without denaturants so that they can be consumed. Ethanol mixes well with water, and you will also find that ethanol is a common ingredient in cosmetics, cleaners and fuels. When using ethanol on the skin as rubbing alcohol it is recommended to dilute it down to about 70%. You can also add in a fragrance to mix with ethanol to make as a disinfectant to use around the home.

Ethanol – Food vs Fuel It is important to realise that not all ethanol is equal, especially when it comes to sustainability. There has been much debate around the use of biofuels taking resources away from food production. This debate mainly refers to the overseas production of ethanol and specifically the use of corn and grains to produce ethanol. The sugar/molasses-based ethanol situation is different, sugar is a sweetener, not a food staple. Unlike corn and grain, sugar contains no protein, fat or vitamins. Other benefits of sugar/molasses based ethanol include:
Methanol & Hydrocarbon Free Bioethanol Why should I be concerned if the bioethanol I have contains methanol or hydrocarbons? Ethanol is exactly the same chemical structure no matter what the feedstock it is products from. However, the added denaturants put into ethanol to stop people from drinking the product varies dramatically. These denaturants are not all equal, and using bioethanol indoors that contains methanol or petrochemical hydrocarbon is unhealthy and dangerous. Some companies promote Methylated Spirit or Industrial Methylated Spirit. In Australia, Methylated Spirit is a technical or industrial grade of ethanol is denatured with hazardous chemicals for industrial applications and not for use indoors. The denaturants used in methylated spirit vary and can commonly contain toxic methanol, Methyl Isobutyl Ketone, Denatonium Benzoate (Bitrex) and in some cases hydrocarbons.

Bioethanol can be made from renewable biological by-products and from sugar production or wheat. In the case of ethanol produced from molasses, it is fermented with water and yeast to product bioethanol. After fermentation has finished, all solids and water are removed by distillation resulting in pure ethanol. The solid matter left after fermenting can be used as stock food or fertiliser and the water can be recycled or used on crops for irrigation. A large percentage of bioethanol produced in Australia is made from molasses. Bioethanol is one of the most common biofuels currently available on the market, biodiesel being the other.

Isopropyl Alcohol or IPA is one of the most common solvents in the world. It is often known as rubbing alcohol or IPA. Isopropyl alcohol is most commonly sold in two purity grades – 70 percent and 100 percent. HINT: ISOPROPYL ALCOHOL IS ALSO KNOWN AS RUBBING ALCOHOL, USUALLY IN ITS 70 PERCENT DILUTION. What can Isopropyl Alcohol be used for? HOUSEHOLD USES OF IPA:
PROFESSIONAL USES OF IPA:
Does isopropyl alcohol kill bacteria and germs? Isopropyl Alcohol (particularly 60 to 90 percent) is antimicrobial against viruses, fungi and bacteria. It kills microorganisms such as bacteria, germs and fungi or halts their growth, specifically the spread of germs. Isopropyl Alcohol kills 99.99% of germs in under 30 seconds making it an in-demand and popular sterilisation solution. What’s the difference between 100% and 70% isopropyl alcohol? The percentage of IPA correlates to the ration of purified water it is diluted with. Pure 100% IPA is not diluted with any water; common formulas include a ratio of 10 – 40% purified water. Does 70% rubbing alcohol kill germs? Yes. Purified water plays an important role in the effectiveness of Isopropyl Alcohol (IPA) as it delays the evaporation rate and therefore increasing the time it remains effective on a surface. 70 percent IPA solutions are most effective in fully penetrating the cell wall, killing the organism. This slightly diluted formula helps to destroy the harmful properties of common pathogens and microorganisms. What is 70% isopropyl alcohol used for? 70% IPA is the most commonly used form of this solvent. It is used to sanitise areas where germs may be present including household surfaces, beauty salons and hospitals. Can 70% Isopropyl Alcohol be used as a Disinfectant? Yes, it is the 70% diluted solution that can act as a disinfectant because the water helps keep the solution on the surface for longer allowing it to penetrate the cell wall of the organism. What is 99%-100% isopropyl alcohol used for? The highly concentrated version of IPA is much less commonly used than 70% IPA. Most often, 99% IPA is used in industrial application or in scientific research, on products that are sensitive to water. How do you dilute isopropyl alcohol to 70 percent? Although pure isopropyl alcohol can be diluted, we suggest purchasing a premixed 70% IPA solution. Not only is 70% IPA less expensive, it is also professionally pre-diluted, therefore removing any potential margin of error for mixing.
