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).

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.

    My liquid laundry soap turned solid. Can I fix it? What did I do wrong?

    Hi, I made this laundry detergent in liquid form and I tried it today using 1/4 of a cup, but it does not foam at all. Is this how it is suppose to be? I’m in doubt that if it doesn’t make foam it won’t wash the clothes well.

    1. Phoria Avatar

      It’s not supposed to foam. Foaming comes from chemicals called surfactants. They don’t make clean–they make suds.

    Hello,
    I’ve just discovered this most amazing website. I can’t wait to try making a ton of things.
    I just have a question. There are so many questions that other readers have, but there is very little in the way of answers, which I would like to see. Am I missing something?
    Thanks very much.

    If I mix a whole box of washing soda (55 oz) and a whole box of borax (76 oz), how many bars of ivory am I supposed to grate? I’m trying to make the powder detergent.

  5. Jamidayle Avatar

    Try adding Citric Acid to your recipe. It whitens, brightens and softens your water. It is amazing!!! It does neutralize the Washing soda, so you have to add enough washing soda to your recipe to work well. The recommended ratio is 4WS:1CA; so, that is 1cup of Washing soda for every 1/4 cup of Citric Acid…it also has a citrus scent.

    *Also…just a note on the Borax for anyone who wants NON-TOXIC….Borax is very toxic if inhaled…this means if you are using in a food processor you have a HIGH chance of inhaling…basically, if you are not using a mask when pour, mixing/ so forth you are taking a HIGH chance of breathing it in…Not to mention…it really doesn’t work unless you are using the liquid version and HOT water. CITRIC ACID can do the job of the borax…but better!!
    *I have also been told that Zote is a good bar of soap to go with if you would like a great scent…and it is a larger bar as well. Hope this helps 🙂

      Hi Jamidayle,
      I came across your post on Citric Acid instead of borax and I love the idea. This is my first time making liquid detergent and I’m thankful I can finally do it. Can the 1c. Washing Soda for every 1/4c. Citric Acid work for the liquid version? For a 5gal. container.; how would I measure the Washing Soda, Citric Acid and a soap bar? I Read that Baking Soda works well too, but I’m not sure on the ratio.
      Thank you,
      Diyanne

      Jamidayle,
      Where can I find Citric Acid? if I use citric acid should I not use Borax? how much water?
      Can you give me your all recipe please

    i have been asked if this is safe for an expectant mother. I think they have borax and boric acid (mild neurotoxin) mixed up…

    We are loving the liquid!! I probably could have halved the recipe since we have an HE washer and only use about a tablespoon every load! At least I know it will last! Gets the clothes clean and has saved me sooo much money! Not to mention my clothes don’t irritate my skin and I won’t have to spend huge amounts of money on “free and clear” detergents when a baby comes along!

    Help! I did the liquid laundry detergent and it looks like a tub of watery fat. What did I do wrong? I can’t even stir it to make it more liquidy.

    Wow, I made the liquid detergent 2 months ago and I LOVE it! I have a nice HE machine and it works perfectly. I made my 2nd batch today because I’m almost out. All my laundry has done fine with this detergent: clothes, towels, blankets, etc. It’s so easy to make and I can’t believe how cheap it is…so much better than paying $18.00 bucks for a jug of Tide! Best of all, no chemicals and no sickening cheap perfume smells. I’ve also been using it in a spray bottle at the kitchen sink to wash dishes. So far so good. Thanks!!!

    Would this stuff (particularly the liquid soap) be safe to use on cloth diapers?

    1. Amanda Avatar

      They don’t recommend using the bar soap recipe on cloth diapers because the soap can coat the diapers making them less absorbent. Also Borax is questionable to use on cloth diapers. I use 1 cup Baby Oxyclean (or the dollar store oxyclean), 1 Cup Baking Soda, and 1 Cup Washing Soda (1 cup of Epsom salts is optional). Then you store that as a powder in a container & use 1 TBSP for the average load of cloth diapers.

    If you’re going to liquefy it, why not start out with liquid Bronners?

    You mention elsewhere on the site that you use soap nuts for laundry. Do you have a preference between this detergent and soap nuts? Have you found one to be more effective and/or cheaper than the other?

    Do you know if this recipe is cloth diaper safe?

    Thinking about making this. I’ve made it before but it was different than yours. After I let it sit overnight. And come time to stir, I filled my gallon jugs half way with warm water than I filled it the rest of the way up with the gel mixture. So it made 10 gallons. Yours it doesn’t say how many gallons and to add water. Please let me know. thank you!

    Hi, I have a quick question. I REALLY want to make this but I don’t have a 5 gallon plastic bucket. All I have is a really big metal pot that would hold about the same amount. Could I leave the liquid soap overnight in this pot instead of the bucket?
    Thanks.

    Hi, thank you for this! I’m going to make the liquid version. I see that you say I can use liquid Dr. Bronners. Do I use the same amount? A bar is 5 oz, does that mean I use 5 oz of liquid?

    Thank you!!

    Mine came out like jello. It won’t come out. Do I just cut the top off of the jug and scoop it out with a spoon to use it?
