Yes, you can use liquid soap in a soap dispenser. In fact, many soap dispensers are specifically designed to dispense liquid soap. Liquid soap is a common type of soap that comes in various forms such as hand wash, body wash, and dish soap. These types of soap are typically more viscous or gel-like in consistency compared to bar soaps.
To use liquid soap in a soap dispenser, you typically need to unscrew or remove the top of the dispenser and pour the liquid soap into the container. Some soap dispensers may have a pump mechanism that you can attach directly to a bottle or refill pouch of liquid soap. Once you have filled the dispenser, you can replace the top or pump mechanism, and it should dispense the liquid soap when you press or pump it.
It's worth noting that different soap dispensers may have different designs or mechanisms, so it's always a good idea to check the instructions or guidelines provided with the specific dispenser you have to ensure proper usage.
