Many people rely on a cup of coffee or two to wake them up in the morning or pick them up during the working day, but now a chemist has come up with a speedy alternative to crafting a cup of coffee.
U.S. biochemist Ben Yu has created ‘Sprayable Energy,’ which claims to be the world’s first caffeine - based topical energy spray. He said tired workers can spray a ‘shot’ of caffeine onto their skin without experiencing a strong buzz, loading up on unnecessary calories or being stuck with a nasty aftertaste like they might get from drinking energy drinks or coffee.
The patent-pending caffeine spray is an odourless liquid that is absorbed through the skin and distributed through the body over a number of hours to deliver a caffeine hit that apparently lasts longer than guzzling a cup of coffee.
Each small aluminum bottle of Sprayable Energy contains around 160 sprays - the equivalent amount of caffeine to 40 cups of coffee and the creators say it is a much cheaper way of getting a caffeine fix than popping to a café. The only active ingredient in the spray is caffeine, which can naturally enter the human body through the skin by passing through cell membranes as it is very similar to nicotine in structure. Each spritz of Sprayable Energy contains around a quarter of the amount of caffeine found in a cup of coffee, but apparently has the same effect as a full cup.
The website said: ‘The reason for this is our product not being ingested, isn’t almost entirely metabolised（新陈代谢） by the liver before entering your system and becoming available to your body.’
‘Thus, a smaller amount of caffeine can have just the same effect as a very large amount of caffeine ingested through an energy drink or cup of coffee. Sprayable Energy`s website recommends that users apply the spray in places where they normally spritz perfume, such as the neck or wrists, but warns users not to exceed 20 sprays a day.
It claims that after spraying the product on the skin, users will feel ‘awake and focused without being over-stimulated’, which is common with coffee and energy drinks.
