What are the differences between regular hand soap anti bacterial hand soap and hand sanitizer?

Regular hand soap primarily cleans hands by removing dirt, grease, and germs through lathering and rinsing with water. Antibacterial hand soap contains added ingredients that specifically target and kill bacteria. In contrast, hand sanitizer, typically in gel form, uses alcohol (at least 60% concentration) to rapidly kill germs without the need for water, making it convenient for on-the-go use, although it may not remove all dirt and grime. While all three options help reduce germs, hand washing with soap and water is generally more effective at removing physical contaminants.
