Revolution: a shampoo dispenser system that uses 2.5 times less shampoo

There are three options of offering personal toiletries (hand wash, shampoo, shower gel, conditioner) to clients in hotel rooms:

1)      Closed dispenser system (non-refillable bottles that can be replaced)

2)      Refillable dispenser system (personal hygiene products in canisters)

3)      Small packets (20 ml, 30 ml and 50 ml small bottles and tubes).


We estimate that hotels use these options equally, i.e., each option is used by approximately 1/3 of hotels. Cheaper hotels mostly use refillable dispenser systems, mid-range hotels closed dispenser systems and expensive hotels generally have toiletries in small bottles. Choose the option depending on the hotel’s vision and consider the following parameters: cost, hygiene, appearance, scents, etc. The advantage of closed dispenser systems and small bottles is that they ensure good hygiene—a client can always count on what is inside the container. The positive side of refillable dispenser systems is that they are cheap for the hotel.

Closed dispenser systems have been relatively expensive because they are made according to the interests of hotel suppliers. The wall mounts of the dispensers are provided to a hotel for free but nothing has been done in terms of economical use of toiletries. In case of the most widespread dispenser systems a hotel guest can even get up to 100 ml of fluid dispensed on their palm per dose and that is clearly a waste. 10 ml of soap is generally enough for one washing and all the rest of the soap in excess of that amount is simply flushed down the drain with water. You need 10–20 ml of shampoo for washing your hair once, and if the dispenser system dispenses 50–100 ml it is a waste several times over. The most common dispenser systems have not been thought through in terms of using toiletries sparingly. Rather, it seems that producers have only wanted to sell as much non-refillable bottles to a hotel as possible. This is what lies behind the understanding that closed dispenser systems are expensive for hotels.

Closed dispenser systems that allow to waste toiletries to such an extent create two large issues:

1)      Big expenses—a hotel’s expenses  on personal toiletries are much larger

2)      Environmental pollution—remarkably greater amounts of washing agents land in the sewer and pollute the environment (Green Key)


The main problem with closed dispenser systems is that the amount of fluid that is dispensed from the container with one push has not been determined but depends upon a hotel guest’s wishes and physical strength. If the dispenser system includes a squeezable bottle then the dispensed amount depends on how strong the user’s hands are—if you squeeze the bottle hard, you can get as much as 100 ml of soap out of it at once. But as only 10 ml is required, it is a waste 10 times over. Is the absence of a specific dispensed dose a pre-planned choice or an “occupational accident”? It is only for the producers to know.

Luckily there are other kinds of products that value a hotel’s interests. The main characteristic of economical dispenser systems is that they dispense a specific dose. The Senser dispenser system, for example, dispenses 4 ml per dose. If a hotel guest needs more of the personal hygiene product for one washing they will press on the dispenser several times. Such a system helps the hotel to save money and is also environmentally friendly. As Green Key is more and more popular, using smaller amounts of personal hygiene products could also become a widespread trend.

Let us view the expenses involved in a closed dispenser system on the basis of a real-life example:

1)      Closed dispenser system without a specific dispensed dose—the hotel uses up 1 replaceable bottle per dispenser in a month, which means 12 bottles per dispenser each year

2)      Closed dispenser system with a specific dispensed dose (e.g., Senser)—the hotel uses up 0.4 bottles per dispenser each month, which means 4.8 bottles per dispenser each year.

A SYSTEM WITH A SPECIFIC DISPENSED DOSE USES 2.5 TIMES LESS PERSONAL HYGIENE PRODUCTS. The hotel can cut costs because hotel guests receive the amount of personal hygiene product they need, and toiletries are not wasted.
