New Range and Formula 99.99% Effective
Ethanol has a quick drying time and does not leave a residual solvent. It is the safest method of sanitizing in any food or pharma setting.
70% Solution is Preferred
Even though ethanol is diluted to a 70% solution, it’s still effective at killing microbes, bacteria, and other microorganisms on the surfaces of counters and food manufacturing equipment.
There are two types commonly available in industry, 70% and 95% - also known as 140 proof and 190 proof. There is 100% but it’s harder to obtain and is only used for specific scientific purposes.
Pure Ethanol Prevents Cell Death
Testing has been done to show that when pure ethanol (at 100%) is poured onto a single celled organism, it will coagulate (clot) its protein. The ethanol penetrates its cellular wall in all directions. The protein located just within the cell wall is what coagulates. It’s much like a defense mechanism. This ring of coagulated protein actually prevents the ethanol from penetrating deeper into the cell wall of the organism. No more coagulation takes place. Basically, this renders the organism dormant, but doesn’t kill it. If the ethanol were to be washed away, then it’s possible the organism would come back to life.
This process defeats the purpose of using ethanol to kill microbes. Instead, scientists have found a way to trick these microbes with a lower percentage of ethanol
How 70% Ethanol Causes Cell Death
In the same study, when the 70% ethanol was poured onto a single celled organism, the ethanol also caused its protein to coagulate, but this occurred at a much slower rate. This actually allowed the ethanol to penetrate the entire cell before it had a chance for its coagulation to block it. The entire cell is then coagulated, causing the cell to die.
What Microbes Can 70% Ethanol Kill?
The water that has been mixed into the ethanol slows the drying time, creating a longer contact time. Ethanol needs to have a contact time of at least 10 seconds to kill Staphylococcus aureus and Streptococcus pyogenes. At a min 10 second drying time, ethanol kills:
- Pseudomonas aeruginosa
- Serratia marcescens
- E. coli
- Salmonella typhosa
- Staphylococcus aureus
- Streptococcus pyogenes
