DIY Liquid Hand Soap (Updated)

The magic of Castile soap and essential oils shouldn't be underestimated! This is the best DIY liquid hand soap I have found for creating an all-natural cleaning routine for your home!

Make this DIY liquid hand soap with a few simple ingredients!

I used to use tons of chemical cleaners, but now I've swapped out all of our soaps for Castile solutions and vinegar washes. We use baking soda, lemon juice, and vinegar on a lot to create a bit more of an all-natural home. 

I will say, there are a few things I won't let go of: Bleach for our sheets and Windex on glass. I also keep a bottle of Clorox countertop spray for anytime I'm dealing with animal discharge... Don't shoot me. 

What is Castile soap?

Castile soap originated in Castile, Spain. It was traditionally made from olive oil, but nowadays many Castile soaps are made from other vegetable fats. It does not contain animal fats. 

Castile Soap is gentle and free of toxins, it can be used on children, pets, and even on vegetables (check dilutions properly)! Once you start using Castile soap, I think you will fall in love with it as it can be used for so. many. things.


We recently switched out our hand soaps for a diluted Castile soap solution, and I was nervous to see if my DIY liquid hand soap would actually clean. Often times my hands are literally black from farm chores...and don't get me started about my fingernails. Soap is an important part of our life. So switching to something homemade was a commitment that needed to be thought through. 

I can confirm that since switching, I have fallen even more in love with Castile soap; I am beginning to believe it is magic. 

Each time I wash my hands, I am so happily surprised with the results. It's not quite as sudsy as store bought soap (no preservatives or additives), but it smells like heaven. 

If you've been considering switching over to a DIY liquid hand soap, I can attest that it is well worth it. The only thing I have noticed is that the soap and the water seem to separate - so I usually give my bottle a swish before using (no biggie). 


Help! I made this recipe and it seems so watery, is this right?

Yes! This soap will be watery. Since Castile soap is so concentrated, you need to dilute it with water first. This will prevent your skin from drying out and will extend your bottle of concentrated soap. It is best to use distilled water; however, I personally just use water from my sink.

The castile soap mixture will be watery, and the soap may settle at the bottom of the jar. If this happens, just give the jar a little swirl before using. I find that I often need to do this, but it has become second nature and it does not bother me at all.

Does Castile soap gets sudsy?

Yes Castile soap will suds up just like your traditional dish or hand soap.

Can I use scented Castile Soap on my dishes?

Yes, I use lavender scented Castile soap for my laundry, dishes, and hands.

Is Castile Soap antibacterial?

Castile soap is considered a disinfectant, and is not antibacterial. To be considered antibacterial, a solution must kill 99.9% of germs. To be a disinfectant, a solution must kill 99% of germs. Adding tea tree oil, which is a natural antibacterial oil, can help make your solution antibacterial, but please note, tea tree oil is toxic to cats.


Make this DIY liquid hand soap with a few simple ingredients!

Supplies (use my affiliates for your convenience):

  • 1/8 C. Castile Soap (I usually add more than this, but 1/8th is what is recommended by Dr. Bronner’s.)

  • 2.5 C. Distilled Water

  • 10-15 Drops Essential Oil (I like lemon)


  1. Fill a glass soap dispenser with 2.5 cups distilled water (to prevent bacterial growth).

  2. Pour in Castile soap (added second to prevent air bubbles).

  3. Finish with essential oils.

Tip: Add a splash of vitamin E oil or liquid coconut oil for added moisture! 

*If you don't have distilled water, you can use tap water.
