I adore Castile soap. Truly. I use it everyday of my life in some way, shape or form. We use it in homemade cleaning products and homemade beauty products that we use everyday. My homemade coconut shampoo, homemade shave cream, homemade body wash and more use it. What I really don’t like about it is the cost though. Buying liquid Castile soap can get really expensive, really quickly! Buying it can run you $15 or more for a 32 oz bottle which means that an otherwise budget friendly DIY suddenly becomes not quite so budget friendly. The solution? I make my own homemade liquid Castile soap for right around $5.00 for 96 oz!
It might seem complicated, but making your own homemade Castile soap isn’t hard at all. We use it so much that I generally end up doing one batch every week or so. It’s incredibly easy to make, but it’s also very budget friendly when you compare it to the other stuff. I buy all of my supplies on ePantry where I pick up the bars of Castile soap needed for only $4.69 each. Amazon is also great for finding a deal on the bar version. The only other true cost I have is the water used and the power used. Since it doesn’t take much of either, the cost breaks down to around $5.00 per batch. At 96 ounces, that comes out to just $0.05 per ounce compared to an average of $0.50 per ounce for commercially made Castile soap.
When you make this version, you’ll use it in your products just like you do the store bought stuff. It’s not quite as thick as the other stuff though so just keep that in mind. It shouldn’t affect your recipes at all. I also use it to make my homemade hand soap, my homemade dishwasher detergent, and my homemade floor cleaner. It has so many uses so having the homemade version on hand really makes it worth it for me. I usually make unscented, however, if you’re looking to replicate something like Dr. Bronners Peppermint Castile soap, you can add any essential oils that you would like.
Homemade Liquid Castile Soap
When you first make this recipe, you’ll have to figure out how thick you want your homemade Castile soap to be. When I first started making it, I only used 4 cups of water, but I found that it was too thick for what I needed it for. At 12 cups, it’s watery but works for what I need. As you make it more and more, you’ll find that happy spot where it’s just perfect for you and your family. Most of the time, I use around 8 or 9 cups and it’s just right for making my cleaning products and things like that.
You will need:
If you want to make this easier on your hands, cut your bar of Castile soap in half with a sharp knife. It is easier to manage the bar when it’s smaller so that things turn out the way you want them to.
Grate the entire bar of Castile soap. If you end up with a big-ish chunk of soap left over, like I often do, you can either save it to melt down into a new full sized bar or you can cut it up into much smaller pieces with a very sharp knife. For those that don’t want to spend their time grating the soap, you can cut it up into smaller chunks and tun it through a small food processor. Just be sure that you only use the processor you use for soap making and things since it will likely end up gunky.
Once you’ve got all of the bar soap grated, add it to a mixing bowl, bucket or if you’re heating your water on the stove, your pot.
Stir it well until the soap shreds melt. If you water cools, you may need to re-heat the water. If you’re using essential oils to give your Castile soap scent, wait until it’s almost cool but still able to be stirred. Add a few drops of the oil you’re using and stir again. Alternatively, you can let it cool some, pour into a mason jar, add the oils and lid and shake till your heart’s content!
If after making your homemade liquid castile soap, you find that your soap is too thin, you can thicken it by making a salt water solution. Add .5 oz regular table salt to 1.5oz warm distilled water and stir until it is dissolved. Then, in very small amounts (1 ml or less), add to your soap and stir. Continue adding the salt water solution to your soap until you’ve got the consistency that you want.
Seriously ya’ll. That’s all there is to it!
