Rubbing alcohol

Depending on what kind of germs you’re trying to kill, 70 percent alcohol is probably more effective than 91 percent for disinfecting.

A 90 percent alcohol solution is too powerful in some cases. It kills the outside of the cell before it can get into the inside and kill the actual germ.

Alcohol percentages

  • To fend off bacteria, a 70 percent alcohol solution with water in it allows it to cross a cell membrane and kills the entire cell.
  • Viruses with an envelope structure, including the new virus, can be deactivated by alcohol solutions of 60 percent.
  • Any concentration of alcohol won't effectively target the norovirus.

Great interesting short snippets of informative articles. Highly recommended to anyone who loves information and lacks patience.

Best app ever! You heard it right. This app has helped me get back on my quest to get things done while equipping myself with knowledge everyday.

Don’t look further if you love learning new things. A refreshing concept that provides quick ideas for busy thought leaders.

This app is LOADED with RELEVANT, HELPFUL, AND EDUCATIONAL material. It is creatively intellectual, yet minimal enough to not overstimulate and create a learning block. I am exceptionally impressed with this app!

Even five minutes a day will improve your thinking. I've come across new ideas and learnt to improve existing ways to become more motivated, confident and happier.

Brilliant. It feels fresh and encouraging. So many interesting pieces of information that are just enough to absorb and apply. So happy I found this.

Laetitia Berton

I have only been using it for a few days now, but I have found answers to questions I had never consciously formulated, or to problems I face everyday at work or at home. I wish I had found this earlier, highly recommended!

Jamyson Haug

Great for quick bits of information and interesting ideas around whatever topics you are interested in. Visually, it looks great as well.
