The short version
After researching the ingredients, certifications, and formulations of the most popular natural laundry detergents, our top pick is Molly’s Suds Original Laundry Powder. It uses a short, plant-based, fragrance-free formula with no synthetic surfactants, dyes, or optical brighteners, which is why it earned our highest Organic Integrity Score of 92 out of 100. For the most transparent multi-use option, Dr. Bronner’s Sal Suds is our pick, and for the most widely available choice, Seventh Generation Free & Clear is easy to find almost anywhere.
A quick note on certification: laundry detergent is not a USDA Organic category, because detergents are not foods or agricultural products. The meaningful signals here are plant-based formulas, third-party marks like EWG Verified, and short, fully disclosed ingredient lists. We say clearly which product carries what. Scores below run from our 92-point top pick to the 72-point value option.
Key benefits of a natural laundry detergent
Detergent residue stays in your clothes, sheets, and towels, so it is in contact with your skin around the clock. Switching to a clean, plant-based detergent gets you a real reduction in that daily exposure. Here is what that gets you.
1. Fewer skin irritants
Fragrance-free, dye-free detergents remove two of the most common triggers for sensitive skin, eczema, and baby skin.
2. No synthetic surfactants or optical brighteners
Plant-based detergents skip petroleum-derived surfactants and optical brighteners, chemicals that coat fabric to look “whiter” but add nothing to actual cleaning.
3. Cleaner for your household and drains
Biodegradable, plant-based formulas are gentler on septic systems and waterways than conventional detergents.
4. Short, readable ingredient lists
The best clean detergents disclose every ingredient, so you know exactly what is touching your skin.
Natural vs conventional detergent: does it matter?
Conventional detergents are built on petroleum-based surfactants with synthetic fragrance, dyes, optical brighteners, and sometimes preservatives, plus trace 1,4-dioxane, a byproduct the EWG flags. A plant-based detergent swaps those for biodegradable plant surfactants and, in the best cases, no fragrance at all.
Because detergent residue never fully leaves your fabric, the difference shows up as daily skin contact. Independent raters like the Environmental Working Group score detergents on exactly these ingredient concerns, and marks like EWG Verified do useful vetting. That is the trade-off our scoring weights: cleaning power balanced against ingredient transparency and skin safety.
How to choose a natural laundry detergent
- Fragrance-free if you can. “Free and clear” or fragrance-free formulas remove the single most common irritant, which matters most for babies, sensitive skin, and eczema.
- Look for third-party marks. EWG Verified and a fully disclosed ingredient list are the strongest signals in a category with no USDA Organic option.
- Plant-based surfactants. Favor plant-derived cleaning agents over petroleum-based ones, and skip optical brighteners and dyes.
- Form factor. Powder, liquid, and concentrate all work; concentrates and powders cut plastic and shipping weight.
- Match your machine and water. Check HE compatibility, and note that some plant powders work best in warm water or with a booster in hard water.
Who this guide is for
The best detergent depends on your priorities. If you want the cleanest, most minimalist formula, our top pick fits. If you want one transparent product for laundry and cleaning, the easiest one to find, a certified pick, or the lowest price, we have a choice for each.

Best overall: Molly’s Suds Original Laundry Powder
| Organic Integrity Score | 92 / 100 |
| Signal | Plant-based, fragrance-free, minimalist |
| Form | Concentrated powder |
| Best for | Sensitive skin, babies, and minimalists |
Molly’s Suds is our top pick because it does the most with the least. The original powder uses a short list of plant-based and mineral ingredients, no synthetic fragrance, dyes, optical brighteners, or fillers, and a little goes a long way. That combination of a genuinely clean formula and real cleaning power is exactly what we score highest.
The trade-off is that it is a powder, so it can need warm water or a quick pre-dissolve in very cold or hard water, and the unscented result will not smell “fresh” the way fragranced detergents do. For sensitive skin and babies, that is the point.
What we liked: Short plant-based ingredient list, fragrance- and dye-free, no optical brighteners, concentrated so it lasts, and genuinely gentle on skin.
Keep in mind: As a powder it dissolves best in warm water; in very cold or hard water, pre-dissolve it or add a booster. Unscented means no “fresh” smell.
What buyers say: Parents and eczema-prone users report fewer skin reactions after switching, and many like how far the powder stretches. A few in hard-water areas add a booster.
Best multi-use: Dr. Bronner’s Sal Suds
| Organic Integrity Score | 87 / 100 |
| Signal | Fully disclosed, biodegradable |
| Form | Liquid concentrate |
| Best for | One clean product for laundry and cleaning |
Dr. Bronner’s Sal Suds is our pick if you want one transparent, concentrated cleaner for laundry and the rest of the house. It is a biodegradable plant-based detergent with fir and spruce essential oils rather than synthetic fragrance, and the brand’s ingredient transparency is second to none.
It scores just below our top pick because it does contain natural essential oils (a plus for most people, but not truly fragrance-free) and, as a concentrate, it needs careful dosing. As a versatile clean detergent it is excellent value.
What we liked: Biodegradable, fully disclosed formula, highly concentrated, and genuinely multi-use for laundry and household cleaning.
Keep in mind: It uses natural fir and spruce oils, so it is not fragrance-free, and as a concentrate you need only a small amount, so measure carefully.
What buyers say: Fans love using one bottle for many jobs and how long it lasts. The main learning curve is dosing, since a little goes a long way.
Best certified formula: Attitude
| Organic Integrity Score | 82 / 100 |
| Signal | EWG Verified |
| Form | Liquid or powder |
| Best for | Shoppers who want a third-party seal |
Attitude is our pick if a third-party seal matters most. Many of its laundry products are EWG Verified, meaning they meet the EWG’s strictest ingredient standards, and the formulas are plant- and mineral-based, vegan, and available fragrance-free.
It scores in the middle mainly on availability and price versus the leaders, but on independent verification it is one of the strongest options in this guide.
What we liked: EWG Verified formulas, plant- and mineral-based, vegan, with fragrance-free options and clear ingredient disclosure.
Keep in mind: Confirm the specific product you are buying carries the EWG Verified mark, since not every variant does, and availability varies.
What buyers say: Buyers who prioritize certifications appreciate the EWG mark and the gentle formula. Some find it pricier than mass brands.
Best widely available: Seventh Generation Free & Clear
| Organic Integrity Score | 77 / 100 |
| Signal | EPA Safer Choice, plant-based |
| Form | Liquid or laundry pacs |
| Best for | An easy-to-find cleaner everyday detergent |
Seventh Generation Free & Clear is the easy-to-find pick. It is a plant-based, fragrance- and dye-free detergent carried by most grocery stores and pharmacies, and the Free & Clear line is a longtime favorite for sensitive skin. Many products carry the EPA Safer Choice label.
It scores a little lower than the leaders because the ingredient list is not quite as minimalist and some variants include more additives, but as a mainstream cleaner detergent you can grab anywhere, it is dependable.
What we liked: Plant-based, fragrance- and dye-free, EPA Safer Choice on many products, and available almost everywhere at a fair price.
Keep in mind: The formula is not as minimalist as our top picks; if you want laundry pacs, note that some prefer to avoid the plastic film, so choose the liquid if that matters to you.
What buyers say: A reliable, widely available choice that sensitive-skin users trust. A few wish the ingredient list were even shorter.
Best budget: ECOS
| Organic Integrity Score | 72 / 100 |
| Signal | EPA Safer Choice, plant-based |
| Form | Liquid, large value bottles |
| Best for | Switching the whole household cheaply |
ECOS is the value pick. It is a plant-based, EPA Safer Choice detergent sold in large bottles at a low cost per load, which makes it an easy way to move a whole household off conventional detergent without a price jump. Fragrance-free options are available.
It scores at the value end because the formula is a bit less concentrated and some scented versions are less minimalist, but for an affordable everyday clean detergent it does the job well.
What we liked: Plant-based, EPA Safer Choice, very low cost per load, with fragrance-free options and big value bottles.
Keep in mind: It is less concentrated than our top picks, so you use more per load, and the scented versions are less minimalist, so pick the free-and-clear option for sensitive skin.
What buyers say: The low cost per load and easy availability win people over. Some in hard-water areas add a booster for tougher loads.
How to use a natural detergent well
Clean detergents work best with a few habits. Do not overdose, since more detergent means more residue, not cleaner clothes. In cold or hard water, dissolve powders first or add a mineral booster. For whites, a scoop of oxygen brightener or a splash of vinegar in the rinse replaces optical brighteners. Wash on the coldest setting that gets your load clean to save energy, and clean your machine monthly so residue does not build up.

Frequently asked questions
What is the best natural laundry detergent?
Our overall pick is Molly’s Suds Original Laundry Powder, because it uses a short, plant-based, fragrance-free formula with no dyes or optical brighteners while still cleaning well. For a multi-use option, Dr. Bronner’s Sal Suds is our pick.
Is there a USDA Organic laundry detergent?
No. Laundry detergent is not a USDA Organic category, because detergents are not foods or agricultural products. The meaningful signals are plant-based formulas, third-party marks like EWG Verified and EPA Safer Choice, and short, fully disclosed ingredient lists.
Is natural detergent good for sensitive skin and babies?
Yes. Fragrance-free, dye-free, plant-based detergents remove the most common laundry irritants, which is why they are widely recommended for babies, eczema, and sensitive skin. Choose a “free and clear” or fragrance-free formula.
Do natural detergents clean as well as conventional ones?
For everyday loads, yes. They may need warm water for powders or a booster in hard water, and for heavy stains a pre-treat helps, but the cleaning power of the leading plant-based detergents is comparable.
Are laundry pacs a good option?
They are convenient, but some people prefer to avoid the plastic film and the fixed dose. If you want the cleanest option, a fragrance-free powder or liquid lets you control the amount.
