Procedure: Get all the items that's needed, Dove and Armand hammer deodorant, 91% Isopropyl Rubbing Alcohol. Sterilize armpits with rubbing alcohol. Apply the Dove deodorant to the left armpit. Apply the Arm and hammer deodorant to right armpit. Workout for exactly 10 minutes. Lightly swab sweat from each armpit and see which deodorant would last longer in smelling. Observe each pit from the beginning to the end and see whats the difference between the two. Photograph and record data in the data table.   Chemistry Research Parabens, Steareths, Triclosan, Propylene Glycol, tea & Dea, artificial colors. Personal and Environmental safety Breast cancer risk with antidepressants, deodorants. The active aluminum based ingredients in antiperspirant deodorants temporarily plugs the swe...

Dove shampoo The three chemical i will talking about that  makes dove men shampoo is sodium chloride, sodium laureth sulfate and cocamidopropyl betaine. These are the three chemical  that are mostly found in dove men shampoo. Also to further my research i looked into these three chemical i looked for all the formals for them. Which they all seem very important in making the dove men's shampoo because that's what gives it good use.  Also i used a shampoo to compare to men dove shampoo which was irish shampoo which wasn't great. The pictures below show all three chemicals formals from the dove men shampoo. Also fun facts did  you know that sodium laureth sulfate comes from petroleum oil. The second fact is that sodium chloride is found naturally in huge geologic of deposit sailt. The last fact i found was for cocamidopropyl betaine was that its a mixture of closely related organic compounds derived from coconut oil and dimethyl . these are facts about the thr...
