Hand soap is a cleaning product designed to remove dirt, germs, and bacteria from the hands. It typically comes in liquid, foam, or bar form and contains surfactants that help lift and wash away impurities. Many hand soaps also include moisturizing agents to prevent skin dryness. Using hand soap is an essential part of personal hygiene, especially before eating or after using the restroom. Regular handwashing with hand soap can significantly reduce the spread of illnesses and infections, making it an important tool in maintaining health and cleanliness.
