What are Biodegradable Soaps?

Simply put, biodegradable soap is one that can be broken down or decomposed by bacteria or other living organisms.

Biodegradable soap is effectively decomposed i.e., it is eliminated or reduced to negligible amounts by organic soil, in contrast to other conventional soaps being used across the country.

Traditional suds, such as those that are likely currently in your kitchen sink or in public restrooms, frequently contain synthetic chemicals.

Chemical preservatives like parabens, phthalates, and petrochemicals, along with artificial dyes and fragrances, do not degrade quickly. If they are disposed of in nature, traces of their chemical composition can persist for many years.

Traditional soaps can hurt the local plants and animals in a lot of ways, which is why you should never use them when camping. And it’s advised for us all to transition to biodegradable soaps to help the environment.

However, the majority of biodegradable washes are made from natural, organic ingredients that decompose quickly when exposed to the bacteria found in soiled environments.

These concentrated solutions can also provide adequate cleaning power while using significantly less product. So, it’s a definite win-win situation in our opinion!

Why Use Biodegradable Soaps?

There are many reasons why you should use biodegradable soaps, but here are the top three reasons to consider them instead of traditional soaps:

Better Ingredients: Many conventional soaps come with harmful ingredients including phosphates, surfactants, and triclosan. On the other hand, biodegradable soaps are made using ingredients derived from vegetables and plants and essential oils that are good for you.

Reduced Environmental Impact: The entire purpose of biodegradable soaps is that they will become undetectable over time when disposed of properly. This way you can use the products knowing that they won’t harm the environment or aquatic life.

Lasts Longer: These products are usually very concentrated and are designed to be mixed with water in most cases. For this reason, a little goes a long way and one small bottle will last a lot longer than traditional soaps.

How to Use Biodegradable Soaps?

Even when using biodegradable soaps instead of traditional soaps, there are certain things to keep in mind. According to the Leave No Trace principles, it’s advised to bathe at least 200 feet away from the nearest water source.

When disposing of dirty water, it’s important to dig a six-inch cathole and dispose of it in it whenever you’re done. This is incredibly important if you love backpacking in National Parks since it’s your responsibility to protect the environment for the years to come.

Doing this will make sure that no water is contaminated, and potential irritants don’t end up in the soil either. This not only protects the flora but also the fauna and thereby ensures that aquatic life is not harmed.

So, make sure to always go through the ingredient list when making a purchase to ensure the product you’re using is free of any harmful chemicals.
