How To Make All Natural Homemade Liquid Dish Soap

Have you ever wondered what’s really in those conventional dish soaps that allow them to cut through grease so easily? Since going natural, I decided to take a look at the ingredient list of a few of the conventional dish soaps that I had been using for years. Not surprising, they were riddled with toxic chemicals that are known to be harmful to your health.

What’s Really In Conventional Dish Soap?

Besides the only natural ingredient “water”, the rest of the ingredients are all chemicals that have been shown to be toxic for our health. Let’s look at some of the ingredients commonly found in those popular dish soaps:

Sodium Lauryl/Laureth Sulfate

this is one of the most common ingredients you will find in most conventional dish soaps, and are known skin and eye irritants, among other health issues.

Lauramine Oxide

Known skin irritant.

PPG-26 – also known as Polypropylene Glycol, this is a known skin and eye irritant.

Triclosan – used for anti-bacterial soaps, this is a known carcinogen and skin irritant that can build up in your system.

Phenoxyethanol – used as a preservative, the FDA states it can cause central nervous system issues, along with vomiting and diarrhea if ingested.

Methylisothiazolinone – another preservative, this chemical is a known skin irritant and some studies have shown it may also be a neurotoxin.

I don’t know about you, but I would like to keep my soap as pure as possible and the best way to do that is to make it at home.

Homemade Liquid Dish Soap Recipe

Remember, this is a recipe for dish soap, the kind you keep by your kitchen sink, not the kind that goes in your dishwasher. I have a recipe on how to make your own dishwasher detergent, because you’re going to have a bad day if you try to use this dish soap in your dishwasher.


This recipe may not work for everyone depending on the type of water you have, so I recommend cutting this recipe in half and testing it before making a big batch.

What You’ll Need What To Do Grate

the castile bar soap in a food processor, or hand grate, until it looks like shredded cheese. Use 1/2 cup and pack tightly together until it forms a nice clump.

Boil 3 cups of water on the stove and add the grated castile soap bar. Stir until completely dissolved.

Remove mixture from heat and add the liquid castile soap and washing soda. Start small with the washing soda and increase amount used for desired consistency. Stir together until well dissolved. Use a blender if needed.

Let the soap sit for 24 hours, stirring occasionally. The soap will thicken over time, so it’s okay if it seems watery at first. If after 24 hours it still seems runny, heat the mixture up again and add 1/2 teaspoon of washing soda until it gets to the desired thickness.

Once the soap has set to your desired thickness, add your essential oils and pour mixture into the soap dispenser.

Alternate Recipe

You can substitute liquid castile soap for the castile soap bar if you don’t want to grate it, or you don’t have it on hand. You’ll have to use a bit more washing soda to thicken it up, but it still works fine.

I find the easiest way to mix everything together is with a blender. This helps the washing soda incorporate more evenly throughout the soap, but you may find some clumps here and there. This soap will also thicken over time, so you may find that it becomes too thick for you to pump out of the dispenser. If that’s the case, simply add a touch of warm water and stir. Make sure to shake the soap container occasionally to help keep it from clumping.

Don’t Want To Make Your Own?

Most of the “natural” soaps found on the market today still have some harsh chemicals in them, like sodium laureth sulfate and others, so it’s really hard to find a true, all natural soap that you can buy.
