Author: Isopropanol, also known as isopropyl alcohol or if you want to be very specific about the chemical nomenclature, propan-2-ol or 2-propanol, is a very important compound in many industries. It is used as a solvent, extracting solution and as a cleaning agent.
Paints, lacquers, inks, gums, resins and cellulose process require isopropanol as a solvent or extracting agent. It is also widely used in the cosmetics and pharmaceutical industries in the manufacture of body lotions, aftershave creams and body rubs. Likewise, because of its inherent antimicrobial properties, it is also a common antiseptic and disinfectant in hospitals, laboratories and other establishments with similar requirements for hygiene and sanitation.
However, what might surprise you is that Isopropanol or Isopropyl alcohol has other uses besides its application in numerous industries. You may not even notice it but you are already using Isopropyl in your everyday routine other than antiseptic, of course.
So let’s lay out the not so common uses of Isopropyl alcohol which you may or may not know yet.
1. Ink stain remover – Though many claim to be permanent inks, they are not really as permanent as you might think. Just dab a cotton ball with a generous amount of Isopropyl alcohol and the stain will be coming right off. However, remember to blot the stain in one direction only to prevent it from spreading.
2. Oil stain remover – Yes, it’s not only effective in removing ink stains but also in getting rid of tough and stubborn oil stains! Soak a paper towel with Isopropyl alcohol and blot the stained area. Again, do not rub since this may just worsen the situation.
3. Printer cartridge cleaner – To keep your printer in good running order, you must regularly clean it and the best way to go about that is to use Isopropyl alcohol. Using a cotton swab dipped in alcohol, clean your printer cartridges. However, do not include the print head or the nozzle plate.
4. Cleaner for your laptop – You can make your own cleaning solution by mixing one part of Isopropyl alcohol with one part water. Ammonia-based cleaners are a no-no because they leave a film. Also, do not apply directly into the surface of your laptop, rather, use a lint-free cloth and moisten it first before wiping and cleaning your laptop.
5. Cleaning agent for crystal chandeliers – Cleaning crystal chandeliers may not be as easy as it sounds. You have to be really careful and hand-wash every individual crystal with a cleaning solution composed of 25% Isopropyl alcohol and 75% distilled water.
6. Cleaning agent for your sound system – To maintain a good audio performance, you have to clean your interconnect sockets by using Isopropyl alcohol and give your connections a good scrub.
7. Remedy for swimmer’s ear – If you plan a weekend at the beach, don’t forget to bring Isopropyl alcohol with you especially if you’re someone who easily gets swimmer’s ears. One of the folk remedies for swimmer’s ear is a 50-50 solution of Isopropyl alcohol and white vinegar.
8. Insect repellant – Mosquitoes are such nuisance but having Isopropyl alcohol nearby and rubbing a good amount on the bites can bring fast relief. Another thing you can do is mix Isopropyl alcohol, vegetable oil and water. Pour the mixture in a sprayer and use it as an inexpensive but effective insect repellant.
These are quite unusual uses of the common Isopropyl alcohol and I bet you haven’t even thought of some of them. These are really great ideas to help you clean household items as well as provide alternative relief to insect bites and swimmer’s ear. So always make sure you have a handy bottle of Isopropyl alcohol inside the house, you’ll never know when you’re going to need it.

Biofuels are created by converting organic matters into fuel so that mankind can be supplied with energy. The biofuels represent alternative ways to stop using the fossil fuels which are already depleting for the near future. Biofuels include under this designation ethanol, derivatives of plants namely sugar cane, corn oils and vegetables. Nonetheless, not all products made from ethanol can be used to generate power. The agency catering for international energy has concluded that ethanol can be used to supply ten percent of the total amounts of gasoline necessary to mankind starting from 2025, and thirty percent of it until 2050. Until now, the percentage remains relatively low, only two percent.
Nonetheless, we can still find a solution to make way for economic and practical changes in the ways biofuels will affect the current and future trends in energy. Studies carried out by scientists have pointed out so far that biofuel can be as much energy efficient as petroleum and traditional fossil fuels. With this in mind, we can easily make an impression on which one will prove to be the most effective in the long term. We need incredulous amounts of energy to provide input energy and this can be done by ensuring that we find some sort of energy source that will not deplete itself. Currently, fossil fuel resources are being depleted at high levels, therefore it is important to have a backup plan that might become the norm in some years from now on. Research has also pointed out that products made from corn ethanol derived sources is twenty percent efficient, compared to the relative success of gasoline, accounting for seventy five percent energy efficiency.
Therefore, it is important to point out that despite the fact that alternative energies and thus biofuels are under research, the ethanol derived from cellulose proved to be eighty five percent efficient, therefore even more that the efficiency of gasoline.
For instance, analysis inside the NYSE, the stock exchange of New York, predict a much wider scale and availability of biofuels to be used to create energy. By spanning the area of the impact of this technology, oil prices can be reduced and thus they can even drop under the crude amount of forty dollars per barrel or even less. Therefore, it is easily possible and predictable that the alternative energy industry would definitely have a negative impact on fossil fuel industries. Some analyses predict that alternative energies, thus biofuels will supply seven percent of total energy demands for transportation by 2030. Therefore, the energy market will definitely be affected in an irreversible way that will make institutions and government authorities unable to regulate the impact of biofuels. If the government nonetheless, agrees to subsidize firm and thus encourage the distribution of biofuels, then the eco friendly alternative will stand more chances in becoming the norm.
Worldwide, there are more nations involved and committed to promoting the usage of biofuels against the usage of more traditional fuels.
These countries include Brazil, who occurs to be the biggest producer of ethanol of them all. It produces ethanol mainly from sugar, around half a billion gallons each year of ethanol production.
While it is the largest consumer of fuels on earth at the moment, the US is also the second largest country producing biofuels, just behind Brazil. Thus, the biofuel quantity produced by the European Union amounts for up to four million tons of biofuel. About eighty percent of the amount of biodiesel fuels coming from the EU is obtained from rapeseed; the rest of it comes from soybean oils and well as some palm oil quantity . These sources represent the remaining twenty percent of the production of biofuel in Europe.
