Let's take a quick look at the advantages and disadvantages of foaming cleanser and how they influenced decisions about sustainability, finances, and the environment.
Foam is formed by the chemical reaction of three different substances: soap or detergent mixed with water and air. The foaming bottle requires a special pump that allows for a precise mixing of liquid cleanser and air to dispense foam with each pump. Liquid cleansers are mixed with air in the foaming chamber to form foam. The foam passes through the coarse net/screen to form homogeneous foam. It will then pass through the fine net / screen to form fine foam before being dispensed through the nozzle.
However, seeing foam does not imply seeing cleaning power in action. Although foam has little cleaning power on its own, its ability to cling to surfaces makes it ideal for cleaning applications.
Water scarcity is a known worldwide issue, and it’s easy to take the water you use for
bathing, washing, and cleaning for granted. However, demand for water is at an all-time high. So, sustainability and environmental awareness should be high priorities.
According to independent industry studies, people who use foaming hand soap to wash their hands use 16% less water to lather and rinse than those who use liquid soap. Water consumption can be reduced by up to 45% if we use the proper washing technique (dispense, lather, tap on, and rinse). Unlike traditional bar or cream cleanser, no water is required to wet the hands when lathering. When the only water used is to rinse the soap away, the efficiency of this method is clear.
The Waste and Resources Action Program (WRAP) in the United Kingdom supports the benefits of foam soap, estimating water savings of up to 50%.
On average, each hand wash requires 36% less product. Foam soap is 8 times easier to spread than lotion soap. It also spreads more quickly, which, when combined with the product's feel, results in a satisfying experience. The product's softness and natural lathering are provided by air bubbles forced into it, requiring less effort from the user. Aside from the financial advantages of using foaming cleanser over cream cleanser, less soap ends up in the environment because less soap is used per wash. Furthermore, because no additional ingredients are required to thicken it, foaming soap is more cost saving and biodegrades more easily.
Foaming soap dispensers release less soap than regular liquid soap dispensers. But does using less soap mean that it is less effective? According to research, there is no significant difference in cleaning ability between 0.7ml of foam soap and 1.1ml of lotion soap.
So, by using foam bottles, we waste less water. But wait a minute. The beauty industry generates a lot of plastic waste. Shampoo, lotion, deodorant, cream, lotion, lipstick, foamer bottles, all come packed in plastic. Single-use plastics are the primary source of plastic pollution on the planet.
Unfortunately, only 9% of the world’s plastic has been recycled. The truth is that the idea of recycling plastic is largely a myth because, out of the 7 types of plastic, only types #1 and #2 could legally be claimed to be recyclable in the United States. Unfortunately, many cosmetics and personal care products use plastics other than types #1 and #2 for their packaging. To make matters worse, plastics that are collected by many of the so-called recycling programs, are downcycled into other products and eventually incinerated or sent to landfills.
What would you do? Use zero-packaging soap and use more water that is badly needed, or save water but use plastic that eventually ends up in landfills and pollutes the oceans?
