Most people love saving money! The only problem is that some ideas turn out costing more money than you actually save, so when trying to save money, you actually need to save money!

Liquid Hand Soap

This diy homemade liquid hand soap recipe will save you money by replacing the more expensive softsoap refills plus it is fun to make!

The secret is to discover tried and true DIY projects that really work. This homemade DIY hand soap recipe does work and we use it all the time.

So, I suggest you find your favorite bar of soap and give it a try.

1. Can’t Beat the Price:

Did you know? Liquid hand soap from the store is quite expensive.

Even at the dollar store, little individual pump bottles of hand soap can add up…..Not to mention all those extra plastic bottles that go into the landfill.

Keeping germs at bay and keeping your hands clean is just good hygiene so having a good supply of inexpensive hand soap is a must! So, it only makes sense to extend your one bar of soap into a half-gallon of liquid hand soap so there is plenty for you to have enough for liquid hand soap refills.

The savings isn’t the only thing to like……so if really love making things and doing things for yourself then this soap project fits right into your homecrafted lifestyle.

Washing Hands with water and soap

Here’s what you need to make your own liquid handsoap:

The average price for a bar of Kirk’s Soap is between $1.25 and $2.00.

2. Instructions to Make your Liquid Hand Soap

This Super Easy Recipe Quick Overview…….

  1. Bring the 1/2 gallon of water to a boil in your large kettle
  2. Grate or chop the 4-ounce bar of soap into small pieces ~ the smaller the better
  3. Add the grated soap to the hot water
  4. Stir until all the pieces have melted
  5. Set the kettle on a hot pad or cutting board to cool
  6. Once the mixture is congealed, you need to stir
  7. Please Note: the mixture can take between 12 to 24+ hours to congeal!
  8. Now is the time to add the optional Vitamin E, essential oils and glycerin*
  9. Make sure to mix well
  10. Using a funnel, pour the liquid soap into your pump bottle
  11. Leave about one inch at the top in order to add a little water to get the proper consistency
  12. Store the extra soap in glass jars in a cool, dark location
  13. Refill as needed
  14. That’s it……..

This is a wonderfully easy but useful recipe.

*If you are adding the optional ingredients, start with the following amounts:

Vitamin E Oil – 4 tablespoons per 1/2 gallon batch

Glycerin – 4 Tablespoons per 1/2 gallon batch

Kirk’s Castile Soap has a nice clean, fresh scent but experiment if you would like with essential oils to create different scents.

I added 8 drops of the following to my latest batch of the following and I love it! Simple, fresh and clean!

~Lavender

~Lemon

~Peppermint

For an Anti-Bacterial Hand Soap add 1 teaspoon of homemade Thieves Oil or Tea Tree Essential Oil to your 1/2 gallon batch

To Begin:

First of all, gather your materials and bar of soap:

pump soap dispenser, grater, bar of soap and a small ceramic bowl

While the 1/2 gallon of water is coming to a boil, you will need to grate your bar of soap like this:

Grating Bar of Soap for Liquid Handsoap

Remove the kettle from the heat when has reached the boiling point and place it on a cutting board or hot pad.

Now, carefully add the grated soap into the hot water. Stir with your wooden spoon after all particles have completely melted and then allow the mixture to cool.

Liquid Handsoap Melting in Kettle

As your soap mixture cools, it will start to semi-congeal. When it has cooled completely mix it up with your wooden spoon or use a hand beater like this. This congealing process can take between 12 and 24 hours so have patience.

Add your optional Vitamin E Oil, essential oils and/or glycerin at this time and mix well. e.

It will seem like it is doing noting and will never congeal and then all of the sudden, voila!, it is congealed and will seem too congealed

It has a high viscosity (molecules sticking together) so it is a bit slimy as it pours through the funnel into your pump dispenser. This semi-congealed soap mixture is now ready to pour into your dispenser bottles.

It is advised to use a funnel to fill your hand soap dispenser bottles but be careful as it kind of pours in globs! You will see what I mean…..and then you will get the knack of being able to fill your dispenser!

I always leave about an inch at the top of each bottle in order to add a little bit of water to get the right consistency of the soap.

For Further Reading on Viscosity. This handsoap recipe actually makes for a fun and interesting homeschool or classroom project plus it is so practical!

3.  Kirk’s Soap is a must…

I find that Kirk’s Coconut Bar Soap is the best soap to use when making your own homemade liquid hand soap; it is plant-based from coconut oil and naturally moisturizing. Plus, it has natural skin-softening glycerin already in.

Quote from Kirks’ Website says it all……..

Gentle Castile Bar Soap

“Our all-vegetable-based bar soap, with 100% Premium Coconut Oil, creates a gentle and creamy lather

even in hard water, leaving skin feeling soft and healthy.”

4. Pump Bottle | Glass Dispenser 

This is one of the most important aspects of liquid soap…..having a convenient dispenser.

Being able to easier dispense your homemade liquid soap is important. I love using a dispenser that fits on a regular mouth canning jar. The actual pump dispensers come in a variety of finishes to go with any decor.

These make the most perfect homemade gift for Christmas, Birthdays, Housewarming or any other special occasion. 

Plus, if you need a wonderful fingernail brush, try this one!

      I just use boiled tap water. Distilled water would be great but will increase the cost a little bit. The tap water has worked well for us. Great question…Thanks for writing!!!

        Mine has never separated. It actually seem to congeal more and sets up but all that needs to be done is to simply stir to bring the liquid hand soap back to the proper consistency. Thanks for writing!

    I have followed instructions, left overnight, but seems to be too thick. Do I add more water?

      Make sure to stir your mixture so it becomes more liquid-like. The goal is to have the mixture thick enough so it pumps properly. After stirring, put a little into your pump dispenser with a funnel to make sure it will pump out. The consistency is interesting, we have 2 different types of pump dispensers and it works well in both. But, if yours does not pump out properly, add just a little bit of water and mix well. You do not want it to be too thin. Did you use the Kirk’s Coco Castille Soap? I have not tried any other type of soap so I am not sure how something else would work. I would think it would be okay but please let me know how it goes! Thanks for writing!

    I just made this last night and still very liquid. Do I have to wait longer or add anything else?

      I have only used Kirk’s Coco Soap…..but, yes, I would wait longer and I am sure it will all the sudden start to gel. It will almost thicken completely but will come back to a pour liquid with stirring. If you store the extra in a jar, make sure to mix it up a bit before pouring into your soap dispenser. Let me know how it turns out…Thanks for writing!

    Hi! Thank you for sharing this! I am at the 60 hour mark and still waiting for the soap to congeal. Have you ever had to wait this long? I used spring water and a homemade coconut/olive oil soap. Maybe it’s not congealing because my soap had natural colorants/essential oils? Thanks in advance for your input 🙂

      Hi Beth….I have only used the Kirk’s Coco Castile bar soap for this recipe so I am not sure. The spring water is perfect, I just have not tried any other soaps. You might try a small test batch, using your uncongealed mixture instead of water and Kirk’s Coco Castille soap. Maybe 1 quart of the mixture and 1/4 bar of Kirk’s grated soap to see if you can salvage your first batch. Let me know how it goes!!! Thanks for writing.

      Did this ever congeal? I’m using a home made bar of canolive II (Coconut, Olive and canola) and after 12hrs had no congeal, was impatient (I know, I know), and added another 4oz bar (hadn’t read enough maybe?) and waited another 12hrs…nothing, waited until 20hrs and checked with a wooden spoon and still watery. Not sure what gives but I’ll wait longer for now…starting to wonder though.

        As I have only used the Kirk’s Original Coco Castile bar soap for this recipe, I am not sure how your homemade coconut canolive bar will work. Give the recipe another try with Kirk’s Castile bar soap to see how it sets up and then in the meantime your other batch may congeal. Thanks for writing.

    Hello, thanks for sharing! Is a preservative needed?

      I have not needed a preservative as this liquid hand soap seems to keep real well. After filling my pump dispensers, I simply store the rest in a quart size canning jar under the bathroom sink. So far, so good ☺ Thanks for writing!
