Is homemade soap biodegradable?

This blog post will answer the question, “I homemade soap biodegradable” and cover topics like biodegradability of soap and frequently asked questions related to the topic.

Is homemade soap biodegradable?

Yes, it is biodegradable.

Is handmade soap natural and biodegradable?

Yes, handmade soap is biodegradable.  Lye, vegetable oils, essential oils, & distilled water are all biodegradable components that may be used to make homemade soap that is guaranteed to be environmentally friendly over time.

You can manufacture and use ecologically friendly homemade soap since you won’t be utilizing the chemicals and less expensive synthetic materials that commercial soap makers often utilize to speed up production, control prices, and create a workable business model for mass manufacturing.

Can soap be produced without lye?

You cannot create soap without Lye since it is necessary for the reaction of animal fats and Lye to form soap. Use melt & pour soap that has already saponified, which you just melt and form, if you want to create soap at home without touching lye.

The key ingredient in mass-manufactured soap that is not as environmentally friendly as handmade soaps is phosphate created chemically.

Phosphates are safe to use in things like soap, so you shouldn’t worry about them personally. They are used due to their effectiveness and low manufacturing costs, although they are not eco-friendly.

Have you ever seen water that is really green and foamy? That is the action of phosphates, which are highly nourishing to the environment but need a delicate balance, which isn’t always favorable.

  • Cover the slow cooker and let the food simmer for thirty min. The mixture ought to rise and bubble.
  • Stir the mixture well after 30 minutes of waiting.
  • In a separate pot, boil your 23 ounces of water. Spoon your soap solution into the water after it has reached a boil. Turn off the heat after adding all of the soap to the water and let it rest overnight to dissolve.
  • Check the pH of the mixture the next morning. The pH of your soap should be between 9 and 10. Add extra lye water if the mixture has a pH lower than 9 or 10. Add extra oil if the pH of your soap combination is greater than 9 or 10.
  • You may add herbs or essential oils to your soap to give it aroma once the pH is right. This step may be skipped completely. If you add aroma, let the soap soak overnight so that the smell may properly distribute across the whole bar.

How to Use Biodegradable Soap Outdoors?

There are a few considerations to make while using biodegradable soap outdoors.

  • Never use biodegradable soap near or in contact with water. This prohibits washing in lakes, rivers, or streams directly. Even though they are natural, the components of soap have the potential to alter the water’s environment by altering the surface tension or adding excess nitrogen.
  • When camping, attempt to dump any soapy water down a grey water drain or dig a hole that is 6 to 8 inches deep and pour your water in there.
  • Wash your hands anywhere you want outdoors at home! Just be careful when disposing of a lot of greywaters, and avoid pouring it straight into the sewer.
  • Because many biodegradable soaps are very concentrated, be sure to read the label and dilute as needed.

Do You Need Biodegradable Soap?

The majority of the chemicals in commercial soaps are difficult to filter out and do not degrade naturally. Water systems or the environment are not harmed by biodegradable soap. 

Use biodegradable soap if you go camping, have an outside sink, or have a septic system.

What Is the Environmental Impact of Biodegradable Soap?

It is not harmful to the environment. When it comes to biodegradable soap, labels aren’t always reliable since various poisons and chemicals might still be concealed in them. 

Instead, carefully review the ingredient list before making a purchase, stick with well-known brands, or try manufacturing your own biodegradable soap.

Why Would Someone Use Biodegradable Soap?

After a year, biodegradable soap has fully broken down. The components don’t hurt the environment since they are natural and unadulterated; they weren’t created in a lab. 

Many commercial soaps may damage plants, generate algal blooms, harm marine life even after treatment, and even upset your septic tank.

How Do You Know if a Soap is Biodegradable?

Start by scanning labels for the phrase “biodegradable” before buying anything. Next, go through the ingredient list. Oils and fats will be used to make natural soap. 

Petrochemicals, phthalates, parabens, and other compounds are found in non-biodegradable materials. Make sure you are familiar with the ingredients!

The Advantages of Homemade Soap

The advantages of homemade soap are listed below:

  • It was created without synthetic materials or chemicals.
  • Waterways are not harmed.
  • It uses glycerin to hydrate your hands more effectively and for a longer period of time.
  • It is devoid of palm oil or only uses palm oil that has been obtained responsibly.
  • It often is vegan and not animal tested
  • Small enterprises provide it
  • Its packaging is often eco-friendly

I will now elaborate on these.

It was created without synthetic materials or chemicals.

The majority of commercial soaps aren’t even real soaps. They are comparable to detergents and are often made with synthetic components. 

These substances, which irritate and dry out the skin, may include parabens, phthalates, triclosan, and phosphorous. Even some of these substances are linked by scientists to cancer and hormone disruption.

Natural oils, clays, mineral colorants, and shea butter are all included in Botanical PaperWorks soap.

Waterways are not harmed.

The majority of handcrafted soaps use biodegradable natural components. In the meanwhile, phosphorus and other synthetic compounds included in commercial soaps leach into rivers and lakes, harming fish and other aquatic life.

It uses glycerin to hydrate your hands more effectively and for a longer period of time.

Glycerin, a kind of lipid that occurs naturally in plants, organically moisturizes and keeps the skin calm. 

In order to extend the shelf life of their goods, many commercial soap producers eliminate glycerin from their soaps. It may be a detergent if the soap label states body washes or body bar.

It is devoid of palm oil or only uses palm oil that has been obtained responsibly.

The palm oil used in many commercial soap manufacturers is sourced from deforested regions.

It often is vegan and not animal tested

Many handcrafted soaps are suitable for vegans since they don’t include any dairy, honey, or animal fats. They are almost certainly cruelty-free since the tiny firms that produce them often don’t test on animals.

Small enterprises provide it

Supporting neighborhood shops that provide homemade soap demonstrates your commitment to the area. Commercial soap producers often manufacture their goods in facilities using machines rather than humans.

Its packaging is often eco-friendly

Unlike many commercial soaps, which are sometimes packed in single-use plastic bottles or heavily-printed, glossy packaging, handmade soap is typically presented without plastics.

Reasons You Should Use Eco-Friendly Soap

Here are the reasons why you should use eco-friendly soaps:

  • Save cash
  • Defense against parabens
  • Sustainable

I will now elaborate on these.

Save cash

Stop wasting your money on high-end or designer personal care products that are laden with toxins. Some cosmetics and personal care items I’ve seen may even cost up to $100 per item!

You won’t pay more than $10 for a good green soap bar. Additionally, it will last a lot longer than body wash or liquid soap. To really save money, buy your soap bars in bulk. 

Alternatively, for all of your cleaning requirements, use an even more cost-effective concentrated multi-purpose solution.

Defense against parabens

Do you know what parabens are? These are preservatives that are often included in soaps as well as other personal care and cosmetic products. 

They are adored by manufacturers because they stop mold and germs from growing within the product, extending its lifespan. Animal studies have shown the possible harm of parabens.

Although the judgment is still out on whether parabens have detrimental effects on humans, many people are no longer ready to take the chance. 

You won’t have to worry about an eco-friendly soap having an adverse impact on your health or the health of a member of your family since it is paraben-free.


Palm oil is found in many popular brand soaps. Due to its role in a significant portion of global deforestation, the production of palm oil has come under fire. This is because oil palms are grown illegally in woods because of their high value. 

Unfortunately, when forests are destroyed, the species that live there are also destroyed. These include tigers, elephants, rhinos, and other critically endangered animals. 

High volumes of CO2 are released into the atmosphere as a result of these forest fires, along with air pollution.

It may be quite difficult for producers to determine if their palm oil production is environmentally friendly and sustainable. The best course of action is to use a palm oil-free, eco-friendly soap instead. 

It should be manufactured from sustainably generated materials like plant-based or essential oils obtained via organic farming and ethical ingredient procurement methods.
