Soap dispenser - what is it, its types

Liquid soap dispenser is a device for dispensing portions of soap, gel / cream or hand sanitizer to visitors to the toilet room.

How do foam dispensers work? There are many different models of soap dispensers on the market. They can differ in the mechanism for:

  • issuing hygiene products
  • the volume and type of consumables (soap, gel, antiseptic)
  • Moreover, size, color and shape

Therefore, before buying a soap dispenser, you should understand the types and features of the installation and maintenance of dispensers.

All soap dispensers are easy to divide into 4 groups:

  1. according to the type of liquid for filling
  2. Moreover, according to the form of supply of consumables
  3. Similarly, according to the type of container
  4. Type of attachment

 Let's consider each group separately.

Which filling liquid to choose?

How do foam dispensers work? Soap dispensers have multiple filling liquid options. Most often, liquid soap, foam soap or antiseptic is common, less often shampoo or shower gel is common to fill. All filling options are suitable for use both in public washrooms and at home.

  1. Liquid soap is the most common filling dispenser. Furthermore, it is economical to use and purchase. When choosing liquid soap, you should pay attention to its consistency and PH level. Gel-like liquid soap with a PH level of less than 10 is the most suitable for use. Too “diluted” liquid soap will lather poorly and, accordingly, will be consumed faster.

In high traffic areas, liquid soap will run out faster and you will need to flush the dispenser more often to avoid soap clumps building up on the unit.

  1. Foam soap (soap-foam) - a foamy substance, the second most popular filling agent. Due to its properties, it consumes much more economically than liquid soap, since soap foam is already ready for washing.

How do foam dispensers work? Many manufacturers add moisturizers with natural extracts to foam soaps that do not dry the skin and have an anti-inflammatory effect.

  1. Antiseptic - a product that is common mainly in medical institutions, catering places for staff and where it is important to maintain the highest possible level of hygiene. Disinfectants serve as a means to protect and disinfect the skin of the hands from pathogenic bacteria.

Antiseptics can be alcohol or water based. Alcoholic antiseptics fight bacteria more effectively than water ones. But you need to remember that when using alcohol antiseptics, the smell of alcohol will still remain on your hands for some time. In addition, alcohol-based products can cause an allergic reaction.

Forms for supplying hygiene consumables

There are two forms of supply of consumables - mechanical and automatic. Soap dispensers can also be of the elbow type. When choosing a form of delivery, you must consider the type of room in which you plan to install the dispenser and the budget that you are willing to spend on it.

1. Mechanical type of dispenser

We need to use the standard form of dispensing hygiene products. To get the right amount of soap, press the button / cap or pull the small lever. Mechanical dispensers are relatively inexpensive in price and are represented by a wide selection of models on the market.

Automatic (touch) dispenser

How do foam dispensers work? An automatic dispenser is more expensive due to the use of a touch sensor for dispensed soap. To use it, just bring your palm to the sensor and get a portion of the hygienic substance. 1-2 ml of soap or gel is automatically dispensed.

The advantages of such a device are in a high level of hygiene - you do not have to touch the device directly to get soap. Touch dispensers can be powered by mains or batteries, there are also hybrid models.

3. Elbow dispenser (with elbow drive)

The elbow type dispenser is mainly common in medical institutions, manufacturing plants, canteens or kitchens. The dispenser with an elbow drive is equipped with a special handle for pushing it with your elbow.

The advantage of this type is the absence of direct contact of the hand with the device and the relatively low price. The downside is the design. As a rule, devices with an elbow drive do not have a stylish design and rich colors.

How do foam dispensers work? When choosing the form of supply of hygiene products, pay attention to the dosing mechanism of the dispenser. It will depend on the method of supplying the liquid in the form of a jet, spray or foam.

For liquid soap, it is preferable to choose a dispenser with a dosing mechanism in the form of a jet, for an antiseptic - a spray, and for foam soap - a dispenser equipped with a special foaming agent.

Types of soap dispenser containers

Soap dispensers can be with removable disposable cartridges or with reusable bulk containers.

  1. Disposable cartridges - are replaceable disposable bottles filled with soap.

The advantage of such dispenser models is that they provide higher hygiene and are inexpensive. So, you buy a dispenser and consumables for it in the form of disposable cartridges.

The disadvantages of using devices with disposable vials are that the consumables must be from the same manufacturer as the dispenser itself, and the high price of the cartridges themselves.

  1. Bulk containers are reusable bottles, which are most often included with the soap dispenser.


The container can be removed and a new amount of soap can be poured.

Advantages of dispensers come with bulk containers with low cost of consumables without reference to a specific manufacturer. Of the minuses - you will need to thoroughly wash the dispenser and the container inside before each refueling.

Before buying such a dispenser, check in advance whether the filling container is included in the standard package of the device.
