DIY Liquid Foaming Soap

Take just a few minutes to make this easy diy liquid foaming soap (or regular liquid soap) with all-natural Castile soap and essential oils.

I have been meaning to share some of the homemade cleaning recipes I use with you for awhile (meaning: years…sheesh), so when I learned that Grove Collaborative had added Dr. Bronner’s Castile soap to it’s product list I knew it was the perfect time to post my all-time favorite way to use Castile soap- in a super easy diy liquid foaming soap!

You will not believe how easy this is to make – and that it consists of only Castile soap, water, and a few essential oils of your choice. That’s it. Don’t you love it? You don’t have to only buy store soaps that have whatever in them (seriously, what?) – you can quickly make your own whenever you need it!

Now, I have to tell you that I wasn’t so sure about a foaming version. I’ve been making regular liquid soap for years and I use it for both hand washing and dish washing – no need for two bottles on the sink, one does it all. So easy. For that you dilute the Castile soap with water in a 1:1 ration (1/2 c. soap to 1/2 c. water).

So when I read (in this article that also has other Castile soap uses you may want to check out) that you could dilute to a 1:4 ratio for a foaming soap, I had my doubts. I mean, Castile soap is made from 100 percent plant oils with no animal products (like tallow), synthetic preservatives, detergents or foaming agents (making Castile soap completely biodegradable and very earth-friendly). How could it be a foaming soap with no foaming agents?

Guess what? I don’t know how, but it really does make an awesome foaming soap! Same ingredients as the liquid soap recipe, just more water (saving more money, yes!) and when you use a recycled foaming soap dispenser, out comes perfect foaming soap. Love it, since I like using foaming soap – it seems to last a lot longer for us.

Need a foaming dispenser?

• Here’s a link for an inexpensive all white bottle
• Here’s a slightly more expensive all silver metal foaming soap dispenser.
• I made the dispenser pictured in these photos from a vintage mason jar and zinc cap, the kind that had a hole in it (I think it was used with glass lids?): I used metal snips to cut the hole bigger and hot-glued a recycled foaming soap dispenser to the top.
• You can do the same thing with reproduction zinc lids, since they don’t have the white caps inside them like most vintage zinc lids do (you’ll just need to actually cut a hole in the top)
• OR you can spend a few dollars more and buy zinc lids with the holes already cut!

It’s really economical, too – the 32-oz bottle lasts a long time when you only use 1/4 c. to 1/2 c. at a time. Our soap lives in our kitchen and last for 2-3 weeks, depending on how many people are using it. You only use a few drops of essential oils, too, making this well under $1 for 1 cup of liquid soap.
