A soap dispenser is a device used to dispense liquid soap for handwashing. They are commonly found in public restrooms, kitchens, and homes. Soap dispensers can be manual, requiring a push or pull to release soap, or automatic, using sensors to detect hands and dispense soap without touch. These dispensers come in various designs and materials, including plastic, stainless steel, and glass. They can hold different types of soap, such as liquid soap, foam soap, or gel soap. Using a soap dispenser helps promote hygiene by reducing the spread of germs and ensuring proper handwashing practices.
