Bar soap vs. liquid soap: the science behind a sustainable choice

In a world where sustainability is becoming increasingly important, choosing the right type of soap is not just a personal preference but also an ecological decision. Let’s take a look at the scientific facts and benefits of bar soap versus liquid soap, especially when it comes to sustainability.

Less Packaging, Less Waste

Soap bar typically comes with minimal packaging, often wrapped in recyclable paper or cardboard. In contrast, liquid soap is usually packaged in plastic bottles that are often not recycled, generating much more waste. According to a study published in the Journal of Cleaner Production, the production of liquid soap can generate up to 20 times more packaging waste than soap bar. That's crazy! Besides that also significantly contributing to plastic pollution and environmental harm.

Energy and Water Savings

The production process of liquid soap requires more energy and water compared to bar soap. Research conducted by the Water Research Center has shown that liquid soap production causes higher water consumption due to the need for additional dilution, stabilization, and packaging. In contrast, bar soap requires less water during production and reduces the need for energy consumption in transporting heavier liquid products.

Longer Lifespan and Efficiency

Soap bar is known for its longer lifespan compared to liquid soap. Because bar soap is more concentrated, you often need less of it to achieve the same cleansing effect as liquid soap. This not only extends the time between purchases but also reduces the overall ecological footprint of your soap consumption.

Natural Formulations and Environmental Friendliness

Many bar soaps are made with natural ingredients and are free from synthetic preservatives and additives commonly found in liquid soaps. These natural formulations reduce the harmful impact on waterways and ecosystems, where chemical residues from liquid soaps can lead to water pollution and damage to aquatic ecosystems.

Conclusion

Choosing bar soap over liquid soap is not only an ecological choice but also a step towards a more sustainable future. By using less packaging, saving energy during production, reducing water consumption, and embracing natural formulations, you contribute to reducing your ecological footprint. Let’s strive together for a world where sustainability is the norm, starting with simple yet important daily choices like the type of soap we use.
