Castile Soap: the Main Ingredient

To make your own foaming hand soap at home, you will need to get something called Castile Soap. It is becoming more and more popular and for good reason! Castile soap is made from 100% plant-based oils and is synthetic free. It is natural, non-toxic, biodegradable, and is gentler on the skin. It is extremely versatile for cleaning in the home and gentle enough for the body. 

The most common and popular brand is Dr. Bronner’s but other off brands are cheaper and work just as well. We like to buy the unscented and add in essential oils to make our soap smell how we like, but if essential oils aren’t your thing, simply buy some scented Castile soap! The Peppermint and Lavender are our favorites.

Here is What You Will Need

To make your own foaming hand soap, you only really need two main things you may not have at home:

  • a Foaming Hand Soap Pump-make sure it’s a *foaming* pump
  • Castile Soap (scented or unscented)

These are the plastic soap pumps Claudia uses. These are the glass soap pumps Lauren uses. And we both buy Castile Soap in bulk from Amazon.

Get The Right Ratios

Castile Soap is extremely concentrated when you buy it, so no matter what you are doing with it, odds are you will want to mix it with water. The correct ratios for foaming hand soap are  3 parts water to 1 part Castile soap

Mix Up Your Homemade Foaming Hand Soap Mix

In a small bowl or liquid measuring cup, stir the water and Castile soap together. If you are using unscented Castile soap, feel free to add in a few drops of essential oils you’d like. The combination of Lemon + Orange or Grapefruit + Rosemary are our personal favorites. PS Use our code BRASHANDCO10 for 10% any essential oils purchased from here!

It will also work just as well keeping it unscented, but if you don’t want to use oils and are wanting a light scent, you can use scented Castile soap, too.

Shelf Life

Once you’ve made your own foaming hand soap, it technically will last 30 days, but I’ve used it much longer than that. But keep in mind you won’t want to mix up a huge batch. It’s best to make what you need as you need it.

So, that’s it! It’s a super simple way to make your own inexpensive and actually amazing *foaming* hand soap at home. We hope you love it as much as we do!
