Molly’s Suds Laundry Detergent Review

Molly's Suds Laundry Detergent Review


The first time I tried Molly’s Suds laundry detergent I knew I would never go back. And here is why.


Overview of Laundry Detergent Market


After I started reading laundry detergent labels (which was three years ago!), I was shocked to learn what laundry detergents are made of! I discovered that most laundry detergents are made of petroleum-based ingredients – even the ones that boast “plant-based,” “biodegradable,” and “natural” claims. By the way, these claims are NOT legally regulated and often loosely used.


One of the problems with petroleum-based ingredients is contamination with 1,4-dioxane, which is a known carcinogen. Also, a lot of laundry detergents have optical brighteners that make fabrics appear brighteners. They coat clothing in the washing machine and can cause skin irritation. Some brighteners do not break down easily and can accumulate in the environment, where they can be toxic to aquatic life and pollute our drinking water.


After extensive research, I found only two laundry detergents that did not have petroleum ingredients, synthetic fragrances, odor-masking agents, optical brighteners and other ingredients I refuse to bring into my home. However, I was not 100% happy because they are liquid.


Molly’s Suds laundry detergent is powdered so there is no big plastic container to throw into the landfill. Yay!!! There is no water in the formulation so you are not paying for transporting water either, contributing to unnecessarily greenhouse gas emissions.


What is Molly’s Suds laundry detergent made of?


There is only good stuff in the detergent. Let’s look together into what it is made of.


Sodium Carbonate (also known as washing soda, soda ash and soda crystals): is rated only 1 out 10 (10 being the most toxic) in the Skin Deep database. It can be derived in a lab with possible added fillers or mined. Molly’s Suds sources its from the Green River Basin in Wyoming.


Sodium Bicarbonate: aka baking soda that we use in food preparations.


Magnesium Sulfate (aka Epsom salt): is an inorganic salt containing magnesium, sulfur and oxygen; is found in sea water and in mineral deposits; is also rated 1 in the Skin Deep.


Unrefined Sea Salt: this is triple filtered in the US, and is food-grade.


Organic Peppermint Oil: organic essential oil that is used in food; the smell is very mild and if you’d like you can this request laundry detergent without it.


So as you can see, Molly’s Suds laundry detergent is as safe as it can be. As picky as I am I can’t find anything to complain about it. With the exception of washing soda and Epsom salt, all the ingredients are food grade. Hide it from children anyway as inhaling or eating this powder is bad for them.


How does Molly’s Suds laundry detergent work?


It works great for me! And I underline for me because if you are used to a laundry detergent with optical brighteners, you might be disappointed. Since I switched from mild petroleum-free laundry detergent, I noticed improvements. The laundry comes out cleaner and brighter.


And it even removes relatively new food stains (1 week old) without soaking or pre-treatment. Here is a before and after picture of my son’s jacket with stains of tangerine juice on it.

And as you can see the stain is 95% gone. Amazing!


Because Molly’s Suds laundry detergent is made of minerals, something tells me that I should not be using it on gentle fabrics such as wool or silk. I might have to continue using Fit Organic detergent for those. I will look into this further.

  1. Thanks for the great article!
    You really teased me. Can you plz just tell us the names of the 2 detergents which you found to be acceptable?
    Some of us care about our health, while not being necessarily so nuts over “environmental” issues.

    Thanks so much!

  2. Thank you Irina.
    I see they’re so expensive. Are the Seventh Generation and Babyganics really that bad in your opinion? Are they at least better than your classic Tide etc?

    Thank you so much!

    1. As a family with single income, I completely understand where you are coming from. On my blog I tend to be more black and white. But when I consult with individuals, I help them make the best decisions for their situation. Yes, Seventh Generation and Babyganics are better than Tide as they do not have optical brighteners, for example. However, they both have petroleum surfactants with possible contamination with carcinogenic 1,4-dioxane and a preservative called methylchloroisothiazolinone, which is a registered pesticide. By the way, if you have Costco membership (or know somebody who does), you should definitely check out your local Costco to see if it carries FIT Organic detergent. It is definitely cheaper there. Let me know if you have other questions. ~Irina

        1. Hi, Nathalie: thank you for asking. To me, it looks like it is as safe as Molly Suds. May I can why you don’t want to go with my recommendation? Is it because you are in Canada? As for efficiency, I can’t say because I have not used Nature Clean but according to the reviews on Amazon here, it looks like it works well. If you are in Canada, could you please let me know if you get redirected to Canadian Amazon when you click on Amazon link here. I am trying to expand my blog to be more helpful for Canadian and UK readers. Thank you. ~Irina

  3. It’s a great find! I shall give it a try! I would also like to mention that for those of us who are really hung up on the idea if getting things cleaner, I could share what I have been doing for years now. This thing can be found at any store that carries laundry products (grocery store, Target, etc.). It’s Borax. It has been used for hundreds of years as a detergent, although it’s not quite a detergent per se (or in that sense as we are accustomed to think of detergents). If I am not mistaken, it’s an organic substance naturally occurring. It has cleaning AND disinfecting properties. It has been used in the forestry as well to naturally get rid of parasites. It has medicinal properties as well. There are some pretty strong followers out there who even take it internally (I haven’t tried that!) to get their bodies rid of heavy metals contamination. As I mentioned, I have been using Borax for years in my laundering. However, I wasnt using it alone , solely as detergent, rather as a addition to my regular detergent.
    Has anyone in this blog tried it? Any comments? Irina, have YOU heard or researched Borax?

    1. Hi Nastia, it is good to hear from you! Unfortunately, studies have shown that it is has endocrine disrupting properties. I recommend being careful with it. This is a good summary on borax. ~Irina

    1. Hi Emilia, I was using ECOS detergent before I found these detergents. I like that ECOS is approved by the Design for the Environment program sponsored by the EPA. So the detergent does not have surfactants that can be potentially contaminated with carcinogenic 1,4-dioxane, which is a big plus. However, unfortunately ECOS detergent contains a chemical called methylchloroisothiazolinone (MCIT), which is toxic to the environment and can cause allergies. For that reason, ECOS did not make my top list. How is ECOS in Whole Foods? Is cheaper than Molly’s Suds? Thanks.

  4. Hi Irina,

    I’m curious to what you think of soap nuts. I’ve used them for awhile now and love them. They work and are environmentally friendly. Any thoughts?

  5. Hi, Irina. Thanks for another great post. I’m getting ready to order laundry detergent so your timing is perfect. Have you tried Grandmas Laundry Soap? The ingredients are: Laundry Lye Soap, Sodium Carbonate (washing soda), Sodium Bicarbonate (baking soda) & Sodium tetraborate decahydrate (borax). What do you think?

  6. Thanks, Irina. I read the info about borax in the link you provided, and I’m one of the ones who thought it was a green cleaner. I recently started using it, but that’s all over now. I’m definitely going to give Molly’s Suds a try. Amazon doesn’t have the unscented version. Would you say the peppermint has a lingering scent?

    1. Judy, I am not a big fan of peppermint smell myself, but after using Molly Suds for about three weeks ( had a post on it) I must say I can’t really smell it at all after the washing cycle is done.
      Irina, thank you for your another informative post! Love your blog!

      1. Sharon, emulsifiers bind water and oils. There is no water because this product is a powder. Some people avoid essential oils; others love them. ~Irina

    1. Yes, you are right, Rochelle! On Amazon it is $13.95 for 70 load bag, and on Thrive it is only $9.95. Thrive offer 25%-50% below retail prices for $59.95 annual membership. And if you are qualified, they even waive the membership fee. Thank you for pointing this out!

  7. Thank you for the informative post. I use Molly’s Suds and I have been happy with it. It is a bit expensive but it lasts a long time. Do you have any thoughts on a brand called Rockin Green? And do you have a stain remover you like to use?

    1. Hi, Stacey! I would love to know more about Rockin Green but they do not list ingredients on their website. Do you have time to ask they for a full list of ingredient of their laundry detergents? ~Irina

  8. Irina, Thank you for all your research. What about Dr. Bronners Sals Suds Biodegradable Cleaner. They claim you can use it for laundry.

    Water, Sodium Lauryl Sulfate, Coco-Betaine, Decyl Glucoside, Abies Siberica (Siberian Fir) Needle Oil, Picea Glauca (Spruce) Leaf Oil, Citric Acid, Sodium Sulfate, Sodium Chloride, Potassium Hydroxide

    1. Hi Ginny: I like Molly’s Suds so much better. Why don’t you try it? What are your concerns about Molly’s Suds? I have not used Dr. Bronner’s cleaner as a detergent. It will probably work because Sodium Lauryl Sulfate is a pretty powerful surfactant, which I avoid in shampoos and other personal care products. I would not recommend it for people with sensitive skin. ~Irina

      1. Thank you Irina, I didn’t even realize that Dr. Bronner’s had Sodium Lauryl Sulfate in it, I’m surprised because I thought all DR. B’s products were healthy and natural. I use Dr. Bronner’s 18-in-1 Pure-Castile Soaps for hand washing. Do you think that is acceptable? I am trying Mollys Suds for laundry and so far I like it. Thanks.

  9. Hi Irina,
    I loved your recommendation for the organic coconut oil bar soap (Soap for Goodness Sake) to do dishes! I tried the Molly’s Suds laundry detergent and was soooo happy with it at first. My clothes look awesome, however, after using for several months, I notice an odor in my front-loading Whirlpool HE washer. I never had this odor before using my old Tide Free & Gentle. I am so careful to dry around the rubber seal of the door, leave it open to dry, etc. but everything I try won’t help with the smell in my washer. Yet, my clothes smell great, no odor. I have the peppermint scented version. Do you experience this odor as well in your washing machine? I just did a load of clothes with a tablespoon of baking soda to experiment (since I don’t want to go back to Tide) and it seems like there is no odor in the machine. Any thoughts? Your help would be greatly appreciated!
    Kind regards,

    1. Hi Andrea: We did not experience any odor. I am not sure what to tell you. But it is good to have your question posted to see if somebody else had similar experience. ~Irina

  10. I have been trying Molly’s Suds lately and I too have had a weird odor coming from my laundry. It smells very bitter. I’m not sure if it’s the detergent or not.

    1. Update: I have been using another detergent lately and I have gotten the same bitter smell, so I’m pretty sure it’s not the Molly’s Suds. I think it’s my washing machine, which I was planning on getting a new one anyway.
      Irina, at the top of this page you used a beautiful picture of a Willow tree, pond and bridge. Can you tell me where you found that graphic? It’s just stunning. Thanks for all you do for us, Ginny

      1. Thank you, Ginny, for letting me know. It is a relief that it is not the product’s fault as I really like this detergent. As for the picture, I am glad you like it. One of my friends abroad, took it. Have a great weekend! ~Irina

  11. Hello! Have you looked into Planet Ultra Powderer Laundry Detergent? I’ve become concerned about the effectiveness of Molly’s Suds as I was told it’s a soap and not a detergent and therefore doesn’t clean porus material appropriately.

    Thank you!

    1. Hi Christen: I am not quite sure what you mean. Molly Suds is not soap. Soap is made by the process of saponification where an alkali is reacted with fat or oil. Soaps are alkaline and detergents are acidic. I agree soaps may not clean clothes especially diapers well especially in hard water. Planet Ultra Powder contains ingredients made with ethylene oxide that I try to avoid if possible. Let me know if this helps. ~Irina

  12. I’m going to try Fit organic detergent for our clothing but I’m concerned about buildup happening on our cotton prefolds. Rather than using the soap nuts what would you recommend for cleaning cotton prefolds diapers? There is a dyi recipe that has the following ingredients:
    Baby oxiclean
    Baking soda
    Soda wash
    Epsom salt
    I’ve read about some dyi laundry soaps not being ph balanced?

    1. Hi, Gemuel: DIY recipes are not easy. There are lots of factors involved: how hard your water is and a type of washing you use. Fit Organic won’t work for cloth diapers. I tried. Molly’s suds have a formulation for cloth diapers. You might want to give it a try. ~Irina

    1. Hi, Christen: Yes, I have. I literally looked into every detergent before I concluded that Molly’s Suds is the best. 🙂 Ecover Zero Powder has ethoxylated ingredients that I am trying to avoid. 🙂 ~Irina

    2. Ok thanks! Sorry, one more product…thoughts on Attitude laundry detergent? How about their Little Ones line? Thank you so much!

  13. Hi Irana, thank you for this article. I am currently switching over to more natural chemical free stuff around the house and was wondering if you have heart of the brand Attitude and what you think of their detergents and other products in general?

    Lots of love,

  14. I recently started using Molly’s Suds and also really like it. I have some items that are 50/50 wool cotton….was wondering if you had looked into using Molly’s Suds for more delicate fabrics yet?

  15. I wash everything with Molly’s Suds: delicates, regular adult and baby clothes, towels and bedsheets, works on everything, just don’t put the wool clothes in your dryer.

  16. Does the Molly’s Suds work well in hard water and an HE washing machine and safe for sensitive baby? Or the Fit Organic you recommended? I have an HE washing machine with water that is on the hard side. After much researching, I found good reviews on Planet, Inc. 2x HE Ultra Laundry Liquid Detergent. It says it has a water softener in it and works well in HE washers.

    It’s ingredients: Water, Laureth-7 (plant-based cleaning agent), Octadecanoic Acid (plant-based cleaning agent), Lauryl Glucoside (plant-based cleaning agent), Sodium Carbonate (mineral alkalinity adjuster), PPG-5-Laureth-5 (plant-based cleaning agent), Sodium Gluconate (plant-based water softener) Does that look good or bad to you?

    Thank YOU!

  17. Oh great, won’t get that! I’m looking into the Mamasuds dishwasher powder and saw they have a laundry detergent. Its ingredients: water, saponified olive oil, sodium carbonate, sodium tetraborate.
    It’s supposed to work good in hard water, have you looked into it and does it look good to you?

  18. Well with the borate free one, do you think it will work with hard water? Because the other one says it’s formulated for hard water, but I guess you’re saying the borate aspect is toxic or not good?

  19. Oh ok great! So I see you recommend the Molly’s Suds laundry powder and the Fit Organic laundry detergent, do you know which one would work better with hard water? I know you really like the Molly’s Suds

  20. Ok awesome!! I’m so grateful I found your blog to help clean out my home! I finally have answers to all my non-toxic researching! Thank you for all of your work! 😂

  21. Hi Irina, I just bought the Molly’s Suds to give it a try. However, with my children having excema I usually try to buy liquid washing detergents (apparently with powder it’s more likely to find residue of the detergent in the clothes hence there is this recommendation to use liquid detergents with eczema). Is there any liquid detergent you would recommend?

    What do you think about Attitude?

    And I usually use Kookaburra for wool clothes. Would you consider it safe?

    1. Hi, Alina: Unfortunately, I am swamped at the moment to be able to give your questions the attention they deserve. Please do not hesitate to hire me for a private consultation. ~Irina

        1. Hi, Kelsey: Norwex detergent ingredients are disclosed so I can’t say much about their safety. If you are a Norwex sales representative, you should encourage them to disclose their ingredients. Thanks. ~Irina

  22. I think (trying to determine if it could be something else, but unlikely) this detergent coats the clothes and creates almost a waterproof barrier. My kitchen towels became nonabsorbent and my jeans’s feel like they have an oil coating on them. I did get the scented one. Could it be the oil in it?? I’d love to solve this puzzle!

    1. Julia and Irina, I have noticed it also! My wash clothes are non-obsorbent! I have been using the Molly’s Suds for couple of years and plan to stick with it. I don’t see the coating effect Julia mentioned on my clothes, but the wash clothes drive me crazy now!

      1. After some more reading I think it’s the HE washer that may be the culprit. This happens mostly with tightly woven cotton – such as kitchen towels, towels, and jeans. They feel grungy. Adding vinegar has not helped! I’m onto trying out another laundry detergent. Maybe the Fit Organics? Ugh!

  23. How odd. I’ve been using it for quite awhile and my towels are great. Maybe the 1/2 cup of vinegar I add to the rinse cycle helps (?)

  24. We have hard water and I know you mentioned you do too. Do you add the vinegar to your wash cycles every time? Or does it work fine without adding the vinegar in hard water? Thank you

  25. Hi Irina, how about Molly’s Sud’s new liquid laundry detergent (Water, Sodium Laurylglucosides Hydroxypropylsulfonate (naturally sourced, plant-based, biodegradable), Potassium Cocoate (pure coconut oil soap), Coco-Glucoside (derived from coconut oil and fruit sugar), Potassium Citrate, Carboxymethyl Cellulose (plant-derived, biodegradable), Xanthan Gum, Sodium Carboxymethyl Inulin (plant-based), Methylglycinediacetic Acid Trisodium Salt (non-EDTA biodegradable chelator)
    and Molly’s suds All-Sport detergent (Purified water, decyl glucoside, vegetable glycerin, plant-based minerals and enzymes, sodium bicarbonate, cocamide MEA, vanilla extract, organic sweet orange essential oil, plant-based alcohol*) for delicates? Do they look good to you?

    1. Hi Monique, I would have to spend more time investigating these two ingredients: Methylglycinediacetic Acid Trisodium Salt and Sodium Carboxymethyl Inulin. ~Irina

  26. Hi Irina,
    I have been using Molly’s Suds powdered detergent per your review and I also saw that they came out with a liquid version. Have you looked into this at all?
    As always thank you,

      1. I’m very excited to try it. Thank you! Having a toddler I struggle with stains. Do you think the Meliora stain stick is better than the Molly’s Suds Oxygen brightener? I must say I LOVE the ingredient list! Thank you so very much!!!!

        1. They are both good but I use them differently. The Meliora stain stick is for treating a stain without washing the whole garment. I use Molly’s Suds to soak and/or add it when doing laundry in a washing machine. Here is a link to Meliora who are interested in trying their products. ~Irina

  27. Hi, I am looking for a new detergent and am interested in Molly Suds. I’m confused as to it not being a soap since one of the ingredients is Potassium Cocoate (pure coconut oil soap) and more confused with their laundry powder that is mineral based. It doesn’t contain any surfactants. Do you know how it cleans clothes then? No matter what I try, my towels keep getting crunchy. I know it’s the water, but I’m trying to find something that will work with it and leave no residue.

  28. Hi, I’m wondering if you’ve tried the liquid version of Molly’s Suds yet. I know it’s come up in earlier conversations. I *think* I’ve narrowed down my choices to either Molly’s Suds-liquid or Ecover liquid. There are so many out there. Thanks for what you do!

    1. Hi, Kristen: I haven’t. Instead, by the time Molly came out with a liquid version, I had found a laundry detergent that I like more. Please read about it here. Let me know what you think. ~Irina

  29. I recently learned about My Green Fills laundry detergent. It is a powder in a reusable container that you add distilled water to, to make the detergent. I wanted to tell you about it in case you wanted to try it and/or provide a review of it. 🙂 thx

    1. Thank you, Fonda. I’ve looked into it before and decided against it. We can talk about it more in the Healthy Consumer Guides membership site more if you’re interested. Thank you! ~Irina
