Supplies / Ingredients

Castile Soap
Dr. Bronners makes a liquid Castile soap that is unscented and great for a gentle foaming hand soap. They also have an assortment of scented Castile soap that can be used as well, depending on your preference. The benefit of purchasing unscented is that you can leave it as is, for those that are sensitive to scents, or you can change up the scent of your soap whenever you want by adding in your own essential oils.

Water
When making your own hand soap it is recommended to use distilled water. I personally just use our filtered reverse osmosis water.

Dispenser
There are a variety of dispensers that you can use, but make sure you have a foaming dispenser! Check out below for my recommendations.

Essential Oils (optional)
If you like scent you can add anything you’d like to make it your own.

FAQ

What type of dispenser do I need?
When making foaming hand soap you need to make sure you have the correct soap dispenser. When picking out a soap dispenser you need to make sure you have one that is specifically for foaming hand soap as it will mix air into the soap mixture to create the foaming soap.

To save money, if you have purchased foaming soap from the store you can simply reuse that bottle when making your own. Or if you are looking to stay away from the plastic containers, this is a great glass option.

We have younger kids and I noticed it was harder for my youngest to fully press down the pump to get the soap out so I purchased this automatic foaming dispenser and it is amazing! I know they are always getting the right amount of soap.

Can I use tap water?
Most places will say it’s best to use distilled water when possible, but we just use our reverse osmosis filtered water. You can use tap water as well but depending on your water source it could make your foaming hand soap go cloudy in the container due to the minerals in the water.

Can I make scented soap?
Yes! One of the benefits to making your own soap is that you can choose whichever scent you would like by just adding a few drops of your favorite essential oils when making your soap.
