How to Make Hand Soap With Castile Soap

Learn how to make hand soap with castile soap.  This is an easy recipe for homemade liquid hand soap, and it saves you a lot of money versus buying hand soap from the stores. 

My kids seem to think that we have an endless supply of hand soap.  I mean, I'm glad that they are washing their hands, but they really don't need to use half of a bottle each time.

I have eczema on my hand, so I can only use a few brands of soap.  Hand soap is my biggest trigger, so I have to use an expensive name brand or learn how to make hand soap with castile soap.

So I learned how to make hand soap with castile soap.  This saves me so much money, and I can still customize it how I want with essential oils or natural fragrance oils.

This recipe for homemade liquid hand soap also doubles as a body wash.  You could use it as a shampoo in a pinch, but I don't personally care for a castile soap shampoo.

How to Make Hand Soap With Castile Soap

You will need liquid castile soap to make this easy hand soap recipe.  I realize that this isn't something that everyone has on hand, so my next post will be how to make a hand soap from a bar of soap.

Why not just use a bar of soap? Well, we prefer to use a liquid hand soap.  With 5 people in the house, bar soaps get mushy.  I use a metal soap dish, but the soap never has time to fully dry because we are using it constantly.

Learning how to make hand soap with castile soap stretches the liquid soap.  This recipe cuts the price per ounce in half, so it saves you even more money.

If you don't normally buy liquid castile soap, you might want to start buying it regularly.  It's inexpensive, and you can use it for so many things in your home.

You can use it to make hand soap, body wash, mop the floor with it, and even wash your dishes with it. 

 Here are 15 ways to use liquid castile soap in your home.

Everyone is freaking out right now buying hand sanitizer, but they were a bit slower to buy hand soap.  The stores here are starting to run out of hand soap now, so I'm glad that I learned how to make hand soap with castile soap.

I also make my own hand sanitizer at home easy recipe.

Can You Use Castile Soap as Hand Soap?

Yes, castile soap is great for a hand soap!  It's gentle, so it's good for the whole family.  You will, however, want to dilute it with water before using it as a hand soap.

How Do You Dilute Castile Soap for Hand Soap?

Generally for a hand soap, you want to dilute it about 1:1 or even 1 part soap to 3 parts water.

Is Castile Soap Good for Skin?

Yes, castile soap is good for skin.  It's a simple recipe made with plant oils, and it's good for sensitive skin too.  It's non drying, so it won't dry out your skin.

Is Castile Soap Better Than Regular Soap?

Castile soap is made just like other soaps with fats, water, and lye.  It's eco friendly because it's made with plant oils. 

It's a gentle soap made with olive oil and sometimes with coconut oil.  

Does Castile Soap Kill Bacteria?

Yes and no.  Castile soap is not anti-bacterial in the sense that it kills germs on contact.  However, it is a surfactant.  A surfactant removes dirt and germs so they can be washed away.  

Liquid Castile Soap

Castile soap is available in a liquid or a bar.  I buy both for different reasons.  If you do have a bar of castile soap, here's how to make liquid castile soap from a bar.

Making it from a bar is perfect for cleaning, but I don't care for it as much to use a homemade liquid hand soap or body wash because it separates.

However, if there's no soap available, it will work just fine to kill germs!

I use Crafty Bubbles liquid castile soap.  I really like the liquid castile soap from Mountain Rose Herbs too.

Dr. Bronner's also makes several kinds of liquid castile soap in different scents.  If you pick up with a scent, omit the essential oils.

I picked up some Equate brand soap from Walmart because I couldn't wait for shipping.  It does not mix well with water, so I don't recommend using it.

Castile soap is a very gentle soap.  True castile soap is made only from olive oil, but olive oil soap doesn't lather well.

Liquid castile soap usually has coconut oil added for better lather.  Depending on which kind you buy, you may not get much lather.  That's fine; you don't need lather to get clean.

Distilled Water

I highly recommend using distilled water when you learn how to make hand soap with castile soap.  Tap water can have bacteria and other germs in it.  If you can't get distilled water, then boil tap water and let it cool completely before you use it.

Carrier Oil

This isn't drying, but you might still want to add a carrier oil.  It's optional, but it will help moisturize your skin.

I recommend using sweet almond oil or grape seed oil.  Both are dry oils, so they won't make your hands feel greasy or oily after you use your handmade soap recipe.

I don't recommend using olive oil or a vegetable oil that you'd use for cooking.  They are heavy oils, and they will leave your hands feeling oily.

I would skip using a carrier oil and use more lotion to keep my hands from getting dry.

Essential Oils

You can use your homemade liquid hand soap unscented or add a scent.  You can try one of these fun essential oil blends that smell like candy if you have kids or want a light, fun scent.   Or make a Thieves oil blend for a Thieves soap.

You can also use the Defender blend from Simply Earth or Shield from Mountain Rose Herbs.

Soap Container

I reuse soap containers for my homemade liquid hand soap when I can.  You can reuse them several times after you learn how to make hand soap with castile soap before the pump finally breaks.

You can also get empty soap containers or buy a pump dispenser for a mason jar.
