Oils on human skin and hair keep them from drying out, but the oils can also attract and hold dirt. The oily dirt is a nonpolar mixture. So washing with water alone wont clean any of the dirt away. So that's where soap comes in! Soaps are salts of fatty acids, which are hydrogen molecules with carboxylic acids at one end...------ Soap has a ionic end that will dissolve in water a longg hydrocarbon portion that WILL dissolve in oily dirt. The dirt is removed from your skin and hair or fabric, suspended in the wash water and washed away:)

The six steps of handwashing are: 1) Wet hands with clean, running water. 2) Apply soap and lather by rubbing hands together, including the backs of hands, between fingers, and under nails. 3) Scrub for at least 20 seconds. 4) Rinse hands thoroughly under clean, running water. 5) Dry hands using a clean towel or air dry. 6) If possible, use a towel to turn off the faucet to avoid recontaminating hands.
