Hundreds of scientific papers have been published about the chemistry of underarm perspiration. The authors of these papers mostly work for cosmetic companies. Their research is very complex. The reason is that simple solutions to biochemical problems usually cannot be patented. Understandably, commercial scientists are employed to find ways their employers can make money with exclusive, patented commercial products.
Deodorants are classified as cosmetics in the United States as long as the manufacturer makes no claim for antibacterial action. If such a claim were to be made, the product risks being reclassified as a drug, and then different regulations apply. Consequently, cosmetic manufacturers do not claim antibacterial action for their deodorant products. This may explain why cosmetic manufacturers have done little to develop deodorant products that attack directly the bacterial causes of underarm odor. Scientists know, however, that bacteria are the direct cause of what we normally associate with underarm odor.
Consequently, cosmetic research aims to find patentable non-pharmaceutical products that mask underarm odor with various perfumes but without necessarily aiming specifically to kill bacteria. A cynic might say that an antibacterial cure for underarm odor would kill the market as well as the odor. Perfume-based products do not carry this risk for cosmetic companies, so there is little incentive to change.
But cosmetic-type products are not the best for dealing effectively with the problem. There are only two things we really need to know about underarm chemistry if we really want to kill the unwanted odor:
Underarm perspiration represents a mildly acidic environment to which odor-generating bacteria are fully adapted.
If you reduce the acidity of the underarm environment sufficiently, the bacteria can no longer survive there. More importantly, if you reverse the acidity sufficiently, you kill the odor-producing bacteria instantly. That is what you need to do.
Knowing this, you can quickly eliminate underarm odor with something you might have in your kitchen or medicine cabinet. The cosmetic companies certainly do not advertise this fact. Naturally, they do not want you to know about it.
All you need is bicarbonate of soda (sodium bicarbonate) and to understand how to use it correctly.
I shall now explain how bicarbonate of soda works to destroy instantly the bacteria causing underarm odor. I give a simple procedure for applying the bicarbonate of soda to affected areas of your skin and explain what you can easily do to ensure clean, healthy skin and unstained clothing.
This really works. You will love it!
How Bicarbonate of Soda Works to Destroy Instantly the Bacteria Causing Underarm Odor
Underarm sweat contains a combination of mild acids (pH=6, approximately). Underarm bacteria evolved to survive in this acidic environment. They needed to become acidic themselves. Their acidity is the fundamental weakness you can exploit. Bicarbonate of soda reacts chemically with them!
Remember your high school chemistry? Add a base chemical (alkali) to an acid and you get a chemical reaction. Bicarbonate of soda is an alkaline substance. Try adding a pinch of bicarbonate of soda to a teaspoon of vinegar (acid) and see what happens! This gives some idea of what happens to the cell walls of underarm bacteria when exposed to bicarbonate of soda. An active chemical reaction first damages and then kills them, all within a few seconds. Nevertheless, the reaction has no noticeable effect on normal skin.
No more live bacteria in your sweat means no more of their odor producing activity!
The Right Product from Your Pharmacy or Grocery Store
So all you need then is bicarbonate of soda (This is NaHCO3 or sodium bicarbonate) or baking soda easily available at your local pharmacy or at your grocery store. But get the right thing.
Please do not confuse bicarbonate of soda or baking soda with baking powder. Although baking powder contains some bicarbonate of soda, it also contains acid powders intended to neutralise the bicarbonate of soda on contact with moisture. The purpose of baking powder is to create bubbles to make dough rise, not to react chemically with the dough itself. Consequently, you cannot count on baking powder to fully reverse the acidity in sweat, and thus is not so destructive of the bacteria dwelling there. If any bacteria survive this weakened treatment; they soon multiply again. So buy bicarbonate of soda or baking soda, not baking powder, and kill all the bacteria.
How to apply bicarbonate of soda to affected areas of your skin.
Wash under your arms first, preferably when taking a bath or shower, and then dry them. This removes sweat containing millions of bacteria, but some bacteria remains in your skin and pores, and would soon multiply. If you have deep or narrow pores, you will need to wash vigorously to open up the pores. Proceed immediately to Step 2 while the pores are still relatively open. Vigorous drying with a fresh towel will help to keep the pores open.
Dampen your fingertips (or a cotton swab, if you prefer) and dip into a small amount of bicarbonate of soda. Spread the dampened bicarbonate of soda widely under your armpits (The first time you do this, apply only to a small area to test for allergy.). This step is easier if you can buy the bicarbonate of soda in a plastic container with a large cap. Rub thoroughly into your pores with a little additional water for coverage and penetration. To get better penetration you can try mixing the bicarbonate of soda with a gentle soap or skin cleanser.
Let the soda bubble down for a minute or two into the microscopic crevices and pores in your skin, destroying as much as possible the remaining bacteria hiding there. The reaction does not noticeably affect normal skin. If by small chance you get an adverse reaction, wash your skin immediately and see the Trouble Shooting section below.
Your armpits should now be virtually free of live odor-producing bacteria, so you can then wash away the bicarbonate of soda and the dead bacteria. This step protects your clothing from visible powder rings if you sweat a lot and leaves your skin in its natural state, free of offensive odor. Sterile sweat is odorless.
Put on clean underwear and clean clothing.
This important final step helps to ensure against rapid re-infection of your underarms by contact with bacteria remaining in unwashed underwear and clothing.
If you bathe or shower frequently and afterwards put on clean clothes, it could be several days or even a week or two before you need to repeat the above procedure.
The actual time will depend on the weather, your environment and physical lifestyle (If you work out in a gym, for example, you get renewed exposure to the bacteria.). If you are very active, you might prefer playing it safe by using the bicarbonate of soda daily, as a matter of routine.
That's it! Simple, safe, inexpensive and effective. Why don't the commercial cosmetic manufacturers come out with a roll-on version of this? Although they cannot patent pure bicarbonate of soda, there are patents for combining it with other ingredients to facilitate roll on. Perhaps we will see this on the market one day soon.
Each of us is a little different. Some have relatively deep (or narrow) pores, for example. In this instance, hot water (not too hot!) applied with a face cloth can open up the underarm pores for better penetration of the bicarbonate of soda and water solution. Vigorous drying with a fresh towel afterwards can help. In addition, you might need to rub in the solution longer and perhaps a little more vigorously into your skin and pores. Adding a little mild skin detergent or mild soap to the solution will aid penetration.
Consider using tea tree oil skin wash (available from herbalists) for this purpose. The tea tree oil ingredient is a powerful anti-bacterial agent. Try it out first on a small area of skin because some people are allergic to tea tree oil.
Finally, some choose to leave a little bicarbonate of soda solution under their arms as an extra precaution. Wipe away sufficient of it to prevent penetration of your clothing with heavy sweating. I suggest washing away the original application before applying this additional solution.
It is important to bathe or shower often and to wear freshly cleaned clothing (preferably cotton).
When trying a new combination, test with a small amount of the solution first to make sure your skin likes it. If you should encounter skin irritation, stop what you are doing immediately and wash away the solution with soap and water. Give your skin a rest and try a different combination of ingredients on another day. You should see your doctor for a diagnosis in any situation affecting your health or well-being.
If your case happens to be difficult, then you can experiment in these ways to find the right combination for you. If you still do not get the desired result, then some part of the odor probably is caused by something other than bacteria. You might decide it's time to see your doctor or dermatologist.
If you like to smoke or take a lot of caffeine, I am sorry to say this could be the ultimate cause of your remaining Body Odor
problem. In this situation, the right course of action is painfully clear.
If you find that bacteria are not really the cause of your problem, then this application is not the complete answer for you, and I will refund your money. The guarantee period is for eight weeks so you have plenty of time for trouble shooting. In any case, you must be satisfied.
The bacteria in your saliva can give you bad breath. A little bicarbonate of soda in water makes an inexpensive mouthwash. It kills bacteria and neutralises the cavity-causing acids they produce. (This is not a long term treatment, daily use is required.) If bacteria are giving you bad breath, this treatment will leave your mouth odor free, without making you smell like a pine tree! It doesn't taste like peppermint, but you can get used to the salty taste of bicarbonate of soda, which you can wash away anyway with water. If you have inflamed gums, add a few drops of 10 vols hydrogen peroxide to the mixture (do not splash any peroxide on your clothes). Of course, you can use the mouthwash as a preliminary to brushing your teeth with your favorite toothpaste. Talk with your dentist or dental hygienist about it next time you see her.
