How to Make Homemade Liquid Foaming Hand Soap:
What You’ll Need:
(affiliate links)
- Dr Bronner’s Castile Soap
, unscented
- Lavender Essential Oil
- Lemon Essential Oil
- Vegetable Glycerin
, optional
- empty foaming soap bottle
– You can just re-use an old foaming soap bottle you may have at home.
To make this homemade liquid foaming hand soap, you’ll need to pour 1/4 cup of castile soap into the empty soap bottle. Add one cup of water.
Add 1 teaspoon of vegetable glycerin if you’d like. This step is completely optional as the castile soap foams just fine alone. But the glycerin gives the soap a thicker, smoother texture.
Then add 5 drops of lavender essential oil and 3 drops of lemon essential oils. If you want a stronger scent then add more in the same ratio. Lemon is a bit stronger than the lavender, so I use a bit less lemon in mine so that the two scents balance. Swirl it around a little to mix together, and your foaming liquid hand soap is ready to use.
That’s it – your foaming liquid hand soap is done!
If you don’t have castile soap on hand, I have also used Seventh Generation dish soap and watered that down 1:1 and used in in my foaming soap bottles.

I’ve never tried making my own soap. It’s sort of surprising to hear that it doesn’t take a lot of effort.
Jenny says
I’ve never tried making my own soap. This looks so easy!
Scott says
We have a foaming soap bottle next to our kitchen sink just for this. So easy to customize the scents!
diane says
I make quite a few of our beauty products and have always had good luck with them. Dr. Bronners is some very useful stuff!
Maura says
Yes indeed Dr. Bronners castile soap rocks!!!
dana vento says
I love your liquid foaming hand soap because honestly we have just tossed great dispensers in the recycle that could have been reused. Fabulous idea
Erika says
I’ve done that too and it always felt like such a waste. Thankfully no more! 🙂
Sharon says
I made these foaming soaps for office staff, and all our family this year for Christmas. Everyone loved them. Thank you for the “recipe”!
Maura says
So glad they turned out well and everyone enjoyed! Merry Christmas!!

Hi! I just came across your recipe and am anxious to make it. I just ordered some peppermint Bronners Castile soap so would I just use the water and the soap without adding any essential oils?
Maura says
Sure Karla you can certainly just do that. But if you want a more intense scent, you can add more peppermint if you’d like or other essential oils that go well with peppermint (like Eucalyptus, Geranium, Grapefruit, Juniper Berry, Lavender, Lemon, Rosemary, and Melaleuca) This is a very versatile “recipe” and can tailor it to however you want it to smell.
Debbie says
I thought you couldn’t put essential oils in plastic. Is this not true with making the foaming hand soap?
Erika says
Yes, some essential oils can erode plastic. They’re typically more acidic, like citrus oils. This foaming hand soap does have lemon essential oil but it’s only a few drops and given the size, I’m not too concerned about it eating away the plastic bottle.
Another reason we used plastic for this soap, is that for many families, mine included, it’s not practical to use glass soap bottles (more easily broken with young children.)
Great point – thanks for mentioning it, Debbie!
