As the desire for sustainability grows, consumers have begun to shift away from conventional products engineered with harmful chemicals in favor of clean, earth and skin-friendly items. Among those are soaps, which have historically been made with some unsafe ingredients to the detriment of people and the environment. During this watershed moment, biodegradable soaps have increased in popularity as the perfect solution for lovers and advocates of the outdoors who also enjoy a good lather every now and again—even in the backcountry.
In this research-driven guide we'll break down all you need to know about biodegradable soap, and which to buy (scroll down a ways to get right to our top picks for the best biodegradable soaps and wipes).
What is Biodegradable Soap?
Unlike conventional soap, biodegradable soaps don’t contain surfactants, short for “surface-active agent”, which bind oil and water together in body products. While they aren’t inherently bad for us (unlike parabens or phthalates—harmful chemical compounds found in soaps used as preservatives that can negatively affect) the hormones in humans and animals, surfactants have been shown to harm aquatic animals and even pose a threat to their watery ecosystem if exposed to enough of those surfactants overtime.
To paraphrase the EPA guide to choosing eco-friendly home cleaning products which have similar ingredients to soaps, the surfactants can break down into “toxic, persistent, and bioaccumulative chemicals” that can eventually begin to degrade aquatic life. So, when it comes to using a biodegradable soap or body wash both indoors or outside, you can feel good knowing that it’s a product designed to do as little harm to you and the environment as possible.
What to Look for When Choosing a Biodegradable Soap
Surfactants aren’t the only chemicals capable of causing damage. Before buying, scan the ingredient list of each soap or body wash and be sure to avoid the following toxic ingredients:
SLS and SLES - Sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES) that are surfactants used as detergents in soaps and body wash to cleanse skin and create a foamy consistency
Parabens and Phthalates - Ingredients used as a preservative, but found to be an endocrine disruptor
Fragrance - An umbrella term for a plethora of unlisted toxic chemicals designed to create a synthetic scent. Opt for fragrance-free soaps or fragrances made with essential oils for a safe alternative
Natural ingredients - Ok, let us be clear, we aren’t saying natural ingredients are harmful, but we are calling out the many companies that use this catch-all term as a way to market a not-so sustainable product as sustainable. Often called “greenwashing”, once you get good at deciphering ingredient lists, you’ll easily spot these unfounded claims a mile away. Other culprits include “eco-friendly” or “all-natural”, which might signal greenwashing if the product label doesn’t back it up.
If you don’t feel confident decoding a product’s list of ingredients or want to learn more, use trustworthy sources like the Environmental Working Group (EWG) and the EPA’s Safer Choice have a comprehensive database of what to look for and what to avoid.
How to Safely Use Biodegradable Soap Outdoors
Versatile and low-impact, biodegradable soaps are great for backpacking or camping because they can be used for dishwashing, laundry detergent, body wash, or hand soap. However, according to Leave No Trace's Seven Principles—the undisputed expert on responsible outdoor recreation—campers should never use soap or dispose of waste water in a water source. Instead, Principle Three recommends “to wash yourself or your dishes, carry water 200 feet away from streams or lakes” or “use a clean pot or other container to collect water, and take it to a wash site at least 200 feet away from water sources.” Biodegradable wipes have also become a hit with campers as a lightweight and easy way to get clean from nose to toes. If you bring them along, just make sure to carry out used wipes along with the rest of your trash to truly leave no trace.
