Craft Your Own Foaming Hand Soap DIY

Washing one’s hands with foaming soap is a much more pleasant experience than regular bar or liquid soap. Not only does a foaming soap lather up really well to help cleanse, but it is easy to rinse off, thus making the process of washing your hands much quicker.

Beyond this, it is estimated that foaming soap for hand washing uses up to 10 percent less water than a liquid soap. Even if you were to simply dilute your current liquid hand wash, and place it in a foaming soap dispenser, you could cut down on your water consumption by a noticeable margin which, in turn, saves you money on your water bills.

While purchasing a foaming hand soap, or diluting your current liquid soap is a valid option, there’s an even more sustainable way to replace your hand wash, and that is by learning how to make foaming hand soap at home!

It’s very simple to make with natural ingredients, and is even more pocket friendly than buying store-bought foaming soap.

But before we dive into the secret recipe for the best homemade foaming hand soap, let’s look at the ingredients and other items required to make it.

What You’ll Need:

  • Water
  • Liquid Castile Soap
  • Essential Oils (for fragrance)
  • Carrier Oils (Jojoba, Coconut, Almond)
  • Foaming Soap Dispenser

NOTE: Be sure to get your hands on a foaming soap dispenser if you don’t already have one. Unlike liquid dispensers, these are designed specifically for this type of soap where air is pushed into the soap as it is released. The air comes from a chamber inside the dispenser and is part of the reason we get that smooth foam for our wash.

How to Make Homemade Foaming Hand Soap

Now, you could just dilute a liquid hand wash with a ratio of four parts water and one part soap to achieve the foam in a dispenser like that, but we’re here to make our own, chemical-free foaming hand soap. So, let’s dive into how to do just that. 

We advise using a dispenser with a volume of approximately 12 ounces or 360ml capacity. The process below works well for the aforementioned amount, getting you plenty of washes from a single batch.

Step One: Wash and Rinse the Dispenser

Before mixing the soap itself, making sure the dispenser has been thoroughly cleaned is paramount. Putting soap into a contaminated bottle defeats the purpose of cleaning your hands; therefore, it should be opened, washed, and rinsed properly. Do this with regular dish detergent for the entire bottle, inside and out, and give the pump the same treatment as well.

Step Two: Add Water to the Dispenser

Pour clean water into the dispenser, filling the bottle up to 70-75% of its capacity. This leaves space for the rest of the ingredients that will top up the dispenser for a full bottle of foaming hand wash.

Step Three: Add Liquid Castile Soap

Now for the key ingredient. Add 2 tablespoons of liquid castile soap to the water; this should be enough for the solution to get a good lather out of each wash. Made from plant-based oils, and nothing synthetic, castile soap is non-toxic, and naturally biodegradable. Having no animal fat content, it is usually made from olive oil, but can also be created from almond or coconut oil.

Step Four: Add Essential Oil

10 drops of an essential oil is what will do the trick for the amount we’re working with. You could use a single oil, or mix and match to make your own combination of fragrances, however, it’s best to add a total of 10 drops only (regardless of how many different oils you would like to use). 

Besides the common scents like lemon, orange, and lavender, there are other essential oils like tea-tree, eucalyptus, and lemongrass that are worth considering. Along with their pleasant, nature-based aroma, these particular oils possess antimicrobial properties, making them a preferred choice for homemade foaming hand soap. 

NOTE: If you have any sensitivity or allergies towards fragrances, it’s recommended to skip adding essential oils, and leave the soap fragrance-free instead. 

Step Five: Add Carrier Oil

A carrier oil is added to the solution to ensure that the soap moisturises your skin as opposed to drying it out. This is especially important during colder and drier seasons to prevent excessively dry hands. 

Oils like jojoba, almond, and coconut are recommended to be added for this purpose. For the batch we are working on, you will only need up to 1 teaspoon full of your chosen carrier oil.

Step Six: Shake Well Before Use

Finally, with the soap solution and essential oils added together, it’s time to mix it all up!


Simply close the lid, and shake the bottle for a good 30 seconds while giving it a few turns to make sure all the ingredients in the solution are combined well. This should be enough, however, if you notice the oils have separated from the water at any given time, simply shake the dispenser to mix it again, and continue using your foaming hand soap as usual.

It is incredibly simple to make your own foam hand wash at home using a few readily available products. The process is quick and economical, making the switch from liquid or bar soap to foaming hand soap well worth it! It also helps you cut down on your water expenditure as foaming soap washes off more easily. Beyond that, the fact that it is natural, far more sustainable, and you have control over the fragrances, makes it both rewarding and fun to create your own foaming hand soap!
