So, we live by this recipe in my house. My husband is OCD about handwashing (anyone else wash their hands 40 times a day? Not me....) and I'm cheap, so the fact that this recipe costs about 90 cents a 1/2 gallon is very appealing to me.
I also love it because it's easier on hands. I find a lot of the commercial liquid soaps to be really drying and they were leaving my husband's hands cracked, bleeding, and ashy. Neither of us have had that issue since I started making our hand soap.
It's also quick. Like, it takes about 5 minutes to prep it. The rest is wait time.
I've played with this recipe a few times and you probably will too because the amount of water you need varies with the bar of soap you choose. This particular recipe has been used very successfully with Dial Gold, and Ivory
To start you need....
A pan that you never intend to cook in again as the soap will never fully come out of it.
Cheese grater
Cutting board or plate
A bar of soap of your choosing
A bottle to put the finished product in
A funnel
A spoon that won't be used for food again
And this cool little guy:
I suppose you can make the soap without it, but it leaves the soap WAY more moisturizing and allows for a friendlier viscosity.
Alright! Are we ready? Let's begin.
Measure eight cups of water into your pot and begin to heat it.
Grate your soap
Kind of looks like cheese, I know. If you chose to use Ivory, it grates as easy as cheese too :) Now, some people prefer a finer grate, but honestly I'm lazy and this one works fine for me. It just takes it a couple of extra minutes to melt...
On to the hard part! Well, not really, it's easy, but there's a word of caution at the end of this. Into your boiling or near boiling water, you are going to dump in 2 Tbsp of glycerin and mix. You don't need to return your water to a boil, just go ahead and add the soap flakes now.
Assuming your stove is on high right now, let me strongly encourage you to TURN IT DOWN! Oh sure, you can leave it on high. It won't hurt the soap. What it will do is cause an unstoppable boiling over that will cake to the inside of your stove and take FOREVER to totally get out of there. I speak from experience here. The goal here is simply to melt the soap flakes. Once they're melted, shut the heat completely off.
Congratulations! Your soap is now complete. You will need to wait until it is cool enough not to melt your container for the next step. Once it is, grab your spoon to give it a final stir first, then grab your funnel and place it in your container, which we're going to assume you've placed in the sink to avoid spills.
Go ahead and cap your bottle. It will be a few hours before you can use your soap since it has to be completely cool in order to thicken.
When it's done, it will act solid in the container. Now, you don't HAVE to do this next part, but it saves a LOT of vein -popping squeezing of the soap into a dispenser later, so save yourself the trouble and just do this. Shake it. A LOT. The more the better. It breaks it up making it pour much easier.
So, there we have it. Enjoy!
