Making your own natural, homemade laundry detergent is one of the easiest parts of a transition to natural living. This natural laundry soap recipe a great way to save money on laundry detergent and is incredibly easy to make. This homemade laundry detergent post is an updated version of this recipe that addresses high efficiency washers and borax safety.

Why Switch to Natural Laundry Soap?

Conventional laundry detergent is loaded with chemicals like sulfates, fragrances, phenols and more. Many brands contain things like petroleum distillates, which are linked to cancer and lung disease. Fragrances in these detergents are made of a mix of harmful chemicals. (This is also why I make my own linen spray.)

Luckily, making your own laundry soap is an easy and fast process! You only need three basic ingredients to make either a powdered or liquid laundry soap:

DIY Laundry Soap Ingredients

  • Washing Soda (Arm and Hammer Brand available at most stores)Borax Powder
  • Borax (20 Mule Team Borax available at most grocery stores)
  • Bar Soap (Dr. Bronner’s,  Ivory, or other natural, unscented bar soap)

Washing Soda and Borax should be available at your local grocery store on the laundry aisle. Natural bar soaps are in the health, beauty, or organic sections of the store, or online. You can also add a couple tablespoons of baking soda to help freshen clothes.

Wonder What’s in These Ingredients?

Borax is a naturally occurring mineral made up of sodium, boron, oxygen, and water. It is an ingredient in most of the natural soaps available now (Seventh Generation, etc.) but it is much more inexpensive to make yourself. There are some concerns about the safety of Borax, but here’s why I feel comfortable using it, especially for laundry.

Washing Soda

Washing Soda, sometimes called sodium carbonate or soda ash, is made from common salt and limestone or found as natural deposits. If you can’t find this locally, you can make your own from plain baking soda with this tutorial. Here are some other great household uses for washing soda.

Dr. Bronner’s soaps are fair trade and made with vegetable castile soap and pure organic oils.

A Note About Soap vs. Detergent

All Natural Laundry Soap Recipes - two ways

As mentioned above, there is chemically a difference between soap and detergent. The advantage of conventional laundry detergents is that they are formulated to work specifically in washing machine environments. Many soaps are designed for skin and are not as strong. Some sources suggest that over time, natural soaps can leave buildup in washers.

I’ve found that while this recipe works well for me, it isn’t suitable for all water types and washer types. If you’ve used natural laundry soap and experienced clothes getting dingy, this may be the reason.

I’ve found one natural detergent that works brilliantly and can be used alone or in combination with homemade laundry soaps like this one. I often add 2-3 Tablespoons of Dr. Bronners Sal Suds per load as a natural detergent. Sal Suds gets out tough stains and odors and is still a natural product (though technically a detergent/surfactant and not a soap).

Don’t Want to Make it?

Homemade Natural Effective Laundry Soap Recipe

We usually make our own detergent, but for times when we are traveling or I haven’t had time to make it, I’ve found a few good brands of eco friendly laundry detergent that actually work (all received an “A” by the Environmental Working Group):

  • My Green Fills Laundry Detergent – Just a warning… after you try this laundry soap, you may be ruined for DIY forever. This is the best smelling non-toxic laundry detergent I’ve tried and it works well on tough stains and dirt. Similar to my favorite all-purpose cleaner, a huge bonus is their eco-friendly approach. The detergent comes concentrated in a small refill packet (hence the name) which you add to warm water in the provided bottle. Super smart!
  • 2 tablespoons Sal Suds + 1/4 cup Baking Soda or Washing Soda (highly effective and super simple!)
  • Ecover Zero Laundry Detergent– Works well, relatively cost effective and low/no risk of developmental or reproductive toxicity and cancer according to the EWG.
  • Emma Eco Me Detergent – Also rated well by the EWG and cleans up to 64  loads for $12. Good scents.
  • Planet Natural Detergent –  Relatively eco-friendly and cost effective at $9 for 32 loads.

Obviously, the most frugal option is to make your own, but these natural alternatives are a good choice if you aren’t able to make your own or don’t want to.

    I made the liquid kind and dissolved it well and left it overnight, covered. Today I am mixing it but it’s got a gel like texture going on and isn’t mixing very well. Is this normal? And do you have any tips on how to get it smooth? Thanks!

    You can also use this recipe for heavy-duty cleaning jobs. Both the washing soda and the Borax have instructions for using as household cleaners on the box, and with the addition of the soap, you get an even bigger boost. And they work really well, and the house smells good and fresh, not chemical-laden, when you’re done.

    I have made this recipe for over a year now using the Fels-naphta soap and just made it last night using one bar of the Castile soap and it is like water this morning??? The Fels used to gel nicely. Any thoughts??

    I am on my second batch of this recipe (the first I made months ago and we have a family of 7 so it lasts a loooooong time) we live rurally and have hard water – I also have an HE machine. my clothes are cleaner and much softer. and they smell so nice – clean actually without that strong perfume smell. I should note that one of my children is an almost 16 year old – track running boy – he stinks! and it even gets that smell out!

    Is this gentle enough for infants and toddlers? I currently have to use Dreft because everything else irritates their skin but its really expensive.

    I am wanting to try this, but am also starting cloth diapers. Will this recipe work effectively for cloth diapers?

    So I made the liquid five gallon bucket, but it didn’t seem to get my clothes very clean at all. I followed the directions precisely. Any advice?

    I have been making my own laundry soap for over a year now, same ingredients as yours minus the soap. I am currently using 2 bars of sunlight soap and I would like to switch over to the Castille soap but don’t want to change my recipe worrying it might not wash as well?? And also wondering if the Castille laundry soap will leave oil like stains on my clothes because it is made of oils? Hope you can help thanks.

    Can I use the lavender or other scented Dr. Bronners bar soap instead of unscented ?

    1. Yaya Avatar

    Katie, your powdered laundry detergent recipe calls for 1 box each of borax and washing soda to 1 bar of soap. I’ve noticed many other recipes call for 1 CUP each of borax and washing soda to 1 bar of soap. Do you mind sharing how you decided on your lower soap content recipe? Thanks!

      If you look again you’ll see farther down where she states to use 2 parts borax and 2 parts washing soda to 1 part bar soap. I end up with 1 cup when soap is grated and therefore use 2 cups each of the borax and washing soda. Hope that helps!
