Effectiveness of Different Deodorant's

How Effective are Different types of Deodorant throughout the day? 

An essential to daily hygiene involves a plethora of things: taking showers, using lotion and using deodorant. Deodorant is a substance(whether that be solid or liquid with the inclusion of spray on deodorants recently) used to trap odors produced by the body. Deodorants are divided into two categories, one being antiperspirants (Blocking sweat glands from releasing sweat) and regular deodorants that just produce good smells. I began running tests on 3 different types of deodorants to see which was not only the most effective but also the after effects they put on my body. The three deodorants that were chosen for this experiment were Dove, Irish Spring and Old Spice.

Chemistry and Safety Concerns 

Like any product produced, tested and advertised on the market its composed of many different types of chemicals. While deodorant is made up of a plethora of chemicals, there are a few that provide the most important qualities of a efficient deodorant. Benzyl Benzoate is a compound within the deodorant that allows for the resistance of bacterial contamination and also prevents the growth of bacteria in the armpits. This is crucial to the foundation of the deodorant because the growth of that bacteria within the pits is what causes the stench that emanates from it. So this compound allows for the bacteria to never form, therefore preventing the odor from being produced. Other compounds found in a variety of deodorants are Aluminum, Propylene Glycol and Sodium Stearate. The Aluminum found in Deodorants (antiperspirant specifically) is used to plug up a persons sweat glands, preventing the pits from sweating in the first place. Sodium Stearate is used in Deodorants to keep it's gel-like texture. Finally Propylene Glycol is a compound used to maintain moisture in any area its applied to. In combination with Aluminum, it allows the pits to be moisturized while also preventing it from producing any sweat. All these elements work in tandem to keep the armpits sweat free but also not completely dry after the use of the deodorant. Unfortunately some of these components are said to produce some health risks. Aluminum used in deodorant some say can lead you to a higher risk of developing breast cancer while also allowing our body to retain some of the toxins they're supposed to release through sweat. Propylene Glycol sometimes can cause irritated skin and Sodium Stearate can be toxic to the body. All these said risks though are never immediate (Except Propylene Glycol because irritated skin can be a result of different types of tolerant skin) and are produced through rare cases and should be taken with a grain of salt seeing as many hygiene products such as these are made synthetically which involve chemicals good and 

Experiment, Procedure and ResultsMy experiment was carried throughout 3 days in which I had worn similar outfits while also making sure I had completed the same routine so I could keep my results as accurate as possible. All 3 days I had done my morning routine while leaving the house exactly at 7:14 and going home after 4:30 straight from home to school. I also made sure to take the same bus to school everyday so the walk it took to get home was also kept consistent for all 3 days. I mentioned earlier that I had worn the same outfit, which included (T-shirt, hoodie, sweat pants). The deodorants used for this experiment were Speed Stick, Old Spice and Dove Men's deodorant. Old Spice This experiment result actually surprised me the most.  When put on, mostly throughout the day it felt as though it was a blob of gel sitting under my arm. It felt as though it took too long to actually settle into my arm pit and therefore didn't do a very efficient job of retaining sweat. Although it smelled good it did not do it's job of retaining sweat and even after the fact changed the texture of my arm almost to a dry feeling. The only positive this deodorant presented was that it gave off a really good smell but in the end came short of what it set out to do as a antiperspirant. Irish SpringBy far the worst candidate, this deodorant produced no positive results. Putting it on felt rough like sandpaper and it didn't last very long throughout the day. I felt as though it had only lasted up until 5th period in which I felt there was nothing keeping the sweat at bay. Afterwards when I had gotten home I had felt my arm pits were very course and unpleasant. Speed Stick lasted the shortest amount of time and provided very little resistance to sweat during this experiment. Dove Men's Dove Men's Deodorant took the cake and provided all the necessary components of a great Deodorant . It didn't feel uncomfortable during the day and I felt no worries of sweat while the experiment was underway. Even better is that after the fact, my underarms were very smooth rather than the course textures of experiments passed. It didn't take too long for the effects to set in and it didn't too long being a gel either. It struck a perfect balance and ended up taking greatest efficiency spot of the 3 candidates.Proposed Improvement Seeing as to how some of the Deodorants posses possibly harmful ingredients and I know its effect of being a good antiperspirant would be lost without them, I feel as though a balance needs to be struck between limiting the harmful compounds and even adding natural ingredients as well. But I feel as though with products like these its impossible to please everyone,so to me as long as it executes what it promises then its a worthy product worthy to put on the market. But the only room for improvement its for those seeking a more all natural approach.
