Transcript of Effect of soaps on bacterial growth. The effect of different types of soaps on bacterial growth To determine the effects of various types of soap on bacterial growth and to identify which is the most effective.armful bacteria is the reason why we have soaps. Soaps are needed and used regularly to prevent the spread of harmful bacteria and infectious disease. The independent variable in this experiment is the type of soap used which will be Dawn dish soap, Mr. Clean, Softsoap hand soap, and Purell hand sanitizer.
Soap is made up of fatty acids (derived from oils or fats) and a base (like sodium hydroxide salt). The soap molecules have hydrophobic (fatty acid chain) and hydrophilic (salt) ends. This combination allows soap molecules to suspend the oils, dirt and germs that are washed away when you soap up.lick Here to return to the search form. Soap molecules are both hydrophilic (likes water and goes into solution) and hydrophobic (repels water). Bacteria (and dirt and oils) get bound to the hydrophobic end of the soap molecules and the hydrophilic end helps it get washed away with water.
