Soap Nuts for Eczema: A Great Natural Soap & Laundry Alternative

I met today’s guest blogger online a few years ago when I was just starting the blog. I was reaching out to online support groups and found Heidi at her eczema FB support page and immediately loved her natural approach. We’d been using soap nuts for eczema as a laundry alternative for a while at that point, so when I saw she loved them as I did, we started chattering away about them. Eventually I asked her if she’d honor us with a story about why she started using soap nuts and she went a few steps further – including tips, facts, and even a recipe for making soap nut liquid!

Again, a big thanks to Heidi for her post!

I want to share with you how great Soap Nuts have been for our son Jayden’s Eczema/Dermographism-Urticaria !!!  We’ve had extreme trouble with our son’s eczema since he was only three months old and he’s now almost four years old.  He seemed to react/flare up with most eczema creams/treatments, upon first application, prescribed or recommended by our GP/Dermatologist for moisturizing his skin and bathing.

I suspected he may have had a sensitivity to something in the creams and I tried to narrow things down, but as you know, it can be very difficult. But I strongly suspected paraffin. It seemed like months of seeing his skin weeping, peeling, scabbing over and getting infected, going back to the GP week after week to be given yet another cream to try and then the whole process started all over again! He was in so much distress and suffered countless sleepless nights with the itching, etc.

I found a solution: Soap Nuts!

I searched the internet for something 100% pure, no parabens, no SLS  etc  and I came across organic virgin coconut oil and soap nuts.  I began to use the coconut oil for moisturizing his skin and the soap nuts for our laundry and baths.  Around the same time, I also started up an Eczema Facebook Group  as I was new to eczema and I felt like talking/sharing information/experiences with others in the same situation would be really helpful. It’s been lovely ever since. The change in skin care was wondrous and the online support is great!!  I’ve met such great people online, other parents experiencing the same who have been of great support. Eventually, we discovered our son (through an allergy skin patch test) does actually have a sensitivity to all forms of paraffin as I suspected.

For the past three years I have been using soap nuts for my son’s bathing, shampooing and laundry. They have been great for his skin and I can’t imagine our life without them!!!!

Information about Soap Nuts

Soap nuts are a dried fruit/husk (not actually a nut!!!) from the soap berry tree.  The soap nuts release saponin (soap) when they come into contact with water.

Soap nuts are:

  • 100% natural and biodegradable
  • Paraben and SLS free
  • Perfume free
  • Hypoallergenic
  • Naturally anti-fungal & anti-microbial
  • Good for people with allergies and skin conditions like eczema and psoriasis.
  • A good value as they can be reused multiple times and last ages!!
  • Great for multiple uses:  soap, shampoo, laundry, jewelry cleaner, fruit & veggie cleaner, pet shampoo, repellant for head lice, etc.

Tips for buying soap nuts:

  • Make sure the inner seed/pit is removed (deseeded) or you will pay more as soap nuts are charged by weight.
  • Nuts should be a nice caramel color and not very dark or black in color.
  • New, unused nuts should also feel dry and not sticky to the touch.

Using soap nuts for doing your laundry:

  • You can use your ready-made soap nut liquid (see below) and pour directly into washing machine,
  • OR place approx six whole soap nut shells into a small cloth wash bag (usually provided by soap nut retailer). Make sure the bag is tied up securely, I double knot.
  • For washes of 30C (86F) or colder, place the bag of Soap Nuts in a little hot water for a few minutes then add the liquid and bag to your wash.  This helps to release the saponins.
  • Optional:  Essential Oils. I use essential oils of lavender as its good for the skin. Add a few drops onto the wash bag and toss it into the washing machine.
  • After the laundry is done, dry your cloth wash bag and soap nuts and re-use.
  • Soap Nuts can be re-used approx 4 -6 times depending on what water temperature you use and the size of your wash. The hotter the temperature, the quicker the soap nuts will need to be changed.
  • After the nuts are all used up, toss them into your compost or distribute them around your plants to decompose.

Making Soap Nut Liquid for the Laundry:

  • Pour 6 cups of water into a saucepan.
  • Add 12-15 soap nut halves.
  • Boil these up in the saucepan for approx 20 – 25 minutes.
  • Add 1-2 cups of water to the saucepan after boiling.
  • Let the liquid cool.
  • Cover a colander with a muslin or cheese cloth and place over a bowl.
  • Drain your soap nut liquid through the cloth. You can reuse your boiled soap nuts – either re-boil, blend up or add to soap nut liquid to soak for heavier concentration.)
  • Pour the liquid into glass jars.
  • Optional – add a few drops of tea tree oil for more anti-bacterial power and for an essential oil scent that is beneficial for the skin.
  • Keep in fridge for 7 – 10 days or room temperature if using immediately. Lasts longer in the freezer. (A note from Jennifer: I like to freeze the liquid in ice cube trays. I then take out 1-2 cubes to use per load of laundry. I also add four drops of tea tree oil to each laundry load.)

How to Use Soap Nut Liquid:

  • Pour directly in the bath.
  • Pour into a soap dispenser and use as a liquid hand soap.
  • Whisk it up in a blender or hand mixer to make a foamy body soap and shampoo.
  • Use as a laundry detergent and pour directly into your washer.

I hope this is helpful for anyone having the same problems we had with our son and I hope you enjoy using soap nuts as much as we do!

    I have always wanted to try soap nuts. I think of it every time I do laundry now, with chemical filled liquid detergent. Maybe it’s time I make the switch?

    • Jennifer on September 6, 2013 at 5:32 pm

      Go for it! It’s worth a try 🙂

    Ohh god..horrible to see such infections. It hurts especially when they happens to kids. all we are finding is the detergents with full of chemicals and additions but people prefer them as they give instant results but with lot of side effects. We need to go for natural products and that why i would like to introduce you people our products that are total organic and natural by time2gonatural.

    How much soap nut liquid do you use to bathe him? My 21-month old girl is having a fungal infection and since I already have soap nuts at home, thought of using them to bathe her. Do you dilute or use it straight in the baby tub? I had just poured 1/2 cup into 1/3 water in the baby tub. Natural bubble bath! I hope it clears her fungal soon. Doc had prescribed some potassium permanganate but I’m not sure how to use it since the instructions only state dilute 1 part to 8 parts, twice daily.

    • Jennifer Roberge on October 5, 2015 at 9:41 am

      Hi think what you used will probably be perfect. You can also try adding apple cider vinegar to the bath as well to help with infections.

      • nylcaj on October 5, 2015 at 9:09 pm

        Alright. Thanks for the tip!

  7. Doyd on October 15, 2015 at 2:22 pm

    Hello Heidi, I just wanted to say thank you. I read your article back in July and since then, I’ve been using Soap Nuts for my 2 daughters. Their eczema are now way better than before and I am mentioning you in my blog ( because I really owe it to you and this article. Take care!

  8. Branden Dillon on November 3, 2015 at 10:07 pm

    This article was extremely encouraging. Your son’s story and experience with soap nuts really show that they work and are completely safe. Thanks for posting this!

  9. Mia on November 28, 2015 at 4:00 pm

    Can soap nuts be used to clean dishes? If not, what product would you recommend?

    • Jennifer Roberge on November 30, 2015 at 11:32 am

      Yes! That’s a great way to use them. I’d just create a good concentrated formula and give it a try!

  10. Tina Harshbarger on January 28, 2017 at 8:11 pm

    Thank you, I’m searching for more information, my family has numerous allergies and we try to leave as small of an imprint as possible. I am going to give them a try.

  11. Matt Jones on August 18, 2017 at 4:40 pm

    I hadn’t heard of these. In my allergy free searches I’d settled on mud soap as the best fragrance free alternative – now I’m not sure any more. Must try these out.

  12. Dorian on October 31, 2020 at 6:28 am

    Thank you very much for this very nice post and help.
    I have a couple of questions on how to use the berry soap once made.

    When pouring in the bath, how much do you use and do you just let the kid soak in the water then dry him off or wash him ?

    Second question, once used as a soap, how lo g do you blend it for ?

    Thank you for your help 😉

  13. Jess on January 9, 2021 at 4:30 pm

    My twin sons are 6 months old and their skin is just like little Jaydens. I’ve had 9 different creams prescribed so far and all of them have made it worse. Ordered some soap nuts. Got to be worth a try!
