Making the Soap
To make homemade foaming hand soap, you'll need a mixture of liquid castile soap and distilled water.
The ratio of castile soap to water is crucial, as it will determine the consistency and lather of your soap.
A general rule of thumb is to use 1 part castile soap to 3 parts water, but you can adjust this ratio to suit your preferences.

What Kind of Water?
Distilled, R.O., or filtered water is best for making a clearer solution.
Using tap water can lead to a cloudy solution due to minerals in the water reacting with the Castile Soap, indicating hard water.
This reaction is harmless and can even be used to test if your soap is truly a soap or a detergent.
Detergents don't react with hard water, so if your solution remains clear, it could be a sign that you're using a detergent.
You can also use this method to test if you have hard water or if your water softener is working.

A small squirt of Castile Soap in your tap water will reveal if it's hard water.
Distilled water is a good option, but R.O. water is even better at removing impurities.
If you don't have access to either, filtered water will do in a pinch.
The type of water you use won't affect the cleaning power of your soap, but it will affect the clarity of your solution.

How to Make a Hand
Making the Soap is a fun and easy process, and I'm excited to share it with you. Start by gathering the necessary materials, including a mason jar or foaming pump soap jar.
Castile soap is a key ingredient in making foaming hand soap, so make sure to add it to the jar first. You can use any type of castile soap you like, but make sure it's the right amount for the size of your jar.
Add water to the jar, leaving enough room for the foaming top. Then, attach the foaming top to the jar until it's tight.
Shaking the jar is the final step in making your foaming hand soap. Shake it for 30 seconds or until the ingredients are fully combined, and you're ready to use it!

How to Make
To start making your own foaming hand soap, you'll need a few simple materials.
You'll need a disposable foaming hand soap bottle, which you can choose based on its appearance. I liked the look of the Method one.
Look for a bottle with a nozzle and foaming mechanism that you can remove, as you won't need those for your DIY soap.
Cut a hole in the middle of the snap lid to fit the soap pump into. You can use a hammer and nail to pierce a few holes in the center of the snap lid, and then squeeze metal snips to cut out a hole.
Cut the hole large enough that the thinner bottom part of the pump fits into the hole, but small enough that the top of the pump sits above it.
Insert the pump into the snap lid, top the Mason jar, and twist on the ring to see how it fits.

Instructions and Tips
To make your homemade foaming hand soap, you'll need to start by filling a foaming hand soap container 1/4 of the way with Castile soap.
Add 10-20 drops of lemon essential oil to give your soap a refreshing scent.
Fill the rest of the way with water, and that's it! Your homemade foaming hand soap is now ready to use.
Regular Handwashing
Regular hand soap is usually a gel-type substance that is either clear or creamy.
You can find regular hand soap in most bathrooms, often in a dispenser or pump top that makes it easy to use.
This type of soap is not meant to be diluted with water, so you can use it straight from the dispenser.
Using regular hand soap is a simple process - just pump some into your hand, rub it in, and rinse with water.
Regular hand soap is effective at cleaning your hands, but it's essential to use it correctly to get the best results.
Make sure to wash your hands for at least 20 seconds, especially after using the bathroom or before eating.

To make a foaming hand soap, start by filling a container 1/4 of the way with Castile soap. This is a crucial first step.
Add 10-20 drops of lemon essential oil to give your soap a refreshing scent. You can adjust the number of drops to your liking.
Fill the rest of the way with water, and that's it! You now have a basic foaming hand soap recipe.
If you're new to making foaming soap, it's worth noting that regular hand soap is usually a gel-type substance that's meant to be used as is, without dilution. But foaming soap is designed to be diluted with water.
To dilute your soap, use a ratio of one part soap to three parts water. This will give you a gentle, foaming soap that's perfect for everyday use.
Here's a simple dilution guide to help you get started:
How to Make a Dispenser
You can make a dispenser inexpensively using an attractive mason jar and the pump from a disposable one. This is what the author did and it's a great way to reduce waste.

There are some nice permanent foaming soap dispensers available on Amazon, but you can also make your own. You could just buy one, but making one is a fun DIY project.
You can use a foam soap pump from a disposable bottle, which you can get for free if you have one lying around. Alternatively, you can buy a new one, but it's not necessary.
A mason jar is a great container to use for your dispenser, as it's attractive and can be refilled. You can find mason jars at most craft stores or online.
You could also just refill the disposable foam soap bottle with a recipe, but making a dispenser from scratch is a more sustainable option.
What Type of Pump Dispenser?
Foaming pumps come in a variety of styles, sizes, materials, price points, and colors.
You can choose between glass and plastic foaming pumps, with glass being a good option for those who prefer the weight and stability it provides.
A major drawback of plastic foaming pumps is that the pump itself can make the bottle top-heavy and prone to falling over when it's near empty.
However, plastic foaming pumps are a good choice for safety in the shower, where it's wet and slippery.
Glass foaming pumps, on the other hand, are less likely to fall over due to their weight and stability.
Some foaming pumps are designed to fit on standard Mason jars, making them a cute and functional option.
You can also find touchless, motion-sensor foaming dispensers that are pretty nifty.
Frequently Asked Questions
Is foaming hand soap just watered down soap?
Yes, foaming hand soap is essentially a diluted version of regular hand soap, with added air to create a rich lather. This means it's often less effective at cleaning hands than its non-foaming counterpart.
Can you turn regular liquid hand soap into foaming soap?

What ingredient makes hand soap foam?
Hand soap foam is typically created by the presence of surfactants like ammonium lauryl sulfate and sodium dodecyl sulfate, which help reduce surface tension and produce a rich lather. These common foaming agents are often used in consumer products to create a luxurious and cleansing experience.
What can I add to liquid soap to make it foam?
To create a rich lather in liquid soap, consider adding coconut oil and castor oil, which produce a lot of bubbles and creamy foam respectively. Combining these oils can create a truly impressive soap experience.
