Bar soap has always been a staple in many households for its convenience, affordability, and effectiveness. But recent research has shed new light on the environmental benefits of choosing bar soap over liquid soap.
A study from the Institute of Environmental Engineering at ETH Zurich found that bar soap cuts greenhouse emissions by about a third compared to liquid soap. This is due to the energy-intensive production of synthetic surfactants and the packaging requirements of liquid soap, which result in ten times more greenhouse emissions than making simple soap. Additionally, bar soap requires one-fifth of the energy to produce compared to liquid soap, with liquid soaps requiring five times more energy for raw material production and nearly 20 times more energy for packaging production.
In terms of ingredients, bar soaps contain fewer harmful substances for both human health and the environment compared to liquid soaps. They are less likely to contain petroleum, use less plastic packaging, and produce lower transportation emissions. Ethical Consumer recommends brands like Bentley Organic and Lush for environmentally friendly bar soaps.
When it comes to packaging, the difference between bar soap and liquid soap is stark. Producing packaging for liquid soap requires 19 times more energy than packaging for bar soap, and distributing liquid soap creates nearly eight times as many carbon emissions due to the bulky, irregularly shaped containers used for liquid soap.
In terms of toxicity, some cleansers, including soaps, can contain untested chemicals or known carcinogens. The Environmental Working Group’s Skin Deep database provides information on product toxicity, with verified products like Codex Beauty’s bar soap and Bravo Sierra being recommended.
The FDA recommends avoiding antibacterial soaps, as they do not provide added protection against viruses like COVID-19 and may contribute to antibiotic resistance. Microplastic pollution is also a concern, as many products still contain plastics under different names despite regulations against microbeads.
To reduce the environmental impact of using soap, consumers can switch from body wash to bar soap, be mindful of how much soap they use per wash, store bar soap dry between uses, set water heaters to 120°F, use low-flow showerheads, and limit time spent in the shower. By making these small changes, individuals can reduce their carbon footprint and contribute to a more sustainable future. When it comes to reducing your carbon footprint, it’s important to consider not just the products you use, but also the resources they require. In the case of body wash, the water and energy you use for washing have a much larger impact on your personal carbon footprint than the choice of soap you use. However, there are sustainable options available that can help minimize your environmental impact.
If you’re looking for sustainable body wash options, here are some recommendations to consider:
Palm Oil-Free Bar Soaps: Palm oil production is a major contributor to deforestation and habitat destruction. Opting for palm oil-free bar soaps can help reduce your impact on the environment. Look for brands that use sustainable plant-based ingredients instead.
Powder-to-Foam Innovations: Powder-to-foam body wash products are a great alternative to traditional liquid soaps. These products require less water and packaging, making them a more eco-friendly option. Plus, they are often made with natural ingredients that are gentle on your skin.
Refillable Options: Refillable body wash products are a sustainable choice as they reduce packaging waste. Look for brands that offer refill stations or refillable packaging options. This not only helps reduce plastic waste but also saves you money in the long run.
Here are some specific sustainable body wash brands to consider:
- Alpine Provisions: Their body wash is made with natural ingredients and comes in recyclable packaging. Plus, proceeds from their products support outdoor education initiatives.
- EcoRoots: This small-batch producer offers organic body soap made with all-natural, vegan ingredients that are suitable for sensitive skin.
When shopping for sustainable body wash, look for certifications like Leaping Bunny, Palm Oil Free from Orangutan Alliance (POFCAP), B Corp certification, and high ratings from the Environmental Working Group’s Skin Deep database. These certifications indicate that the product has been vetted for its environmental and ethical practices.
In conclusion, making a conscious choice in selecting sustainable body wash products can help reduce your carbon footprint and contribute to a healthier planet. By choosing products that are gentle on the environment and your skin, you can make a positive impact with every shower.
