Best Non-Toxic Laundry Detergents (What I’d Actually Repurchase)

Your laundry detergent is one of the most important products to get right in a low-toxin home — because it’s something you use every single day.
You can read our full guide to the non-toxic cleaning products we actually use here.
The challenge is finding one that actually works. A clean ingredient list doesn’t mean much if your clothes don’t come out clean.
These are the only detergents I’ve personally used and would actually repurchase — based on real performance in our home.

What Actually Matters in a Non-Toxic Laundry Detergent
There’s a lot of noise in this category. Here’s what I actually pay attention to:
- Fragrance-free vs unscented. These are not the same thing. “Unscented” can mean a masking fragrance was added to cover chemical odors. “Fragrance-free” means no fragrance compounds at all. Always look for fragrance-free.
- Residue on clothes. A good detergent rinses clean. If your clothes feel coated, smell heavily scented after washing, or trigger skin reactions, residue is likely the culprit. This is especially important for bedding and anything worn close to skin.
- Ingredient transparency. Every brand on this list discloses their full ingredient list. If a company won’t tell you what’s in their detergent, that’s enough reason to choose something else.
- Performance. Non-negotiable. A detergent with a clean ingredient list that doesn’t actually clean your clothes isn’t a solution. Everything on this list has passed real-world testing in our home.
- Powder vs liquid. We primarily use powder in our home. Powders tend to have simpler formulas, longer shelf life, and less packaging waste than liquids. That said, both formats can be effective — it comes down to preference and what works in your machine.
The Non-Toxic Laundry Detergents I’d Actually Repurchase
1. 9 Elements Laundry Detergent
Best for: Anyone who wants a clean, reliable detergent available at Target with same-day pickup.
9 Elements is our most convenient option and the one I reach for when we need something quickly. It’s powered by vinegar, has a short and simple ingredient list, and is free of synthetic fragrance, dyes, and phosphates. The formula is straightforward and the brand is transparent about what’s in it.
Performance is consistent across all load types. It handles everyday laundry well without leaving residue or fragrance behind. It’s available at Target — including same-day Drive Up — which makes it genuinely accessible in a way that a lot of natural detergents aren’t.
Any downsides? It’s a liquid, which means more packaging than a powder option. For those trying to reduce plastic, Charlie’s or Truly Free may be a better fit. But for day-to-day convenience, 9 Elements is hard to beat.
Would I repurchase? Yes — it’s a permanent part of our rotation for its convenience alone.
If you want the easiest place to start, this is it.
2. Charlie’s Soap Laundry Powder
Best for: Those who want the simplest possible ingredient list and excellent value over time.
Charlie’s Soap might be the most stripped-down detergent on this list — and that’s exactly why it’s one of my favorites. The formula contains just a handful of ingredients, all of them doing actual cleaning work. No fillers, no fragrance, no unnecessary extras.
Performance is excellent. It cleans thoroughly, rinses completely clean, and doesn’t leave any residue on fabric. Because it’s highly concentrated, a little goes a long way — which makes it one of the most economical options on this list over time.
We get the best price through Azure Standard, but it’s also available on Amazon if you’re not an Azure member. Either way it’s worth keeping stocked.
Any downsides? The powder format requires a small amount of measuring, which is a minor adjustment if you’re used to liquid. It’s also not something you’ll find at a local grocery store, so a little planning ahead is needed.
Would I repurchase? Yes — one of the most reliable detergents we’ve used.
If you prefer powder and want the cleanest, simplest formula, this is the one.

3. Truly Free Laundry Detergent
Best for: Families who want a subscription-based refill system with strong performance and minimal plastic waste.
Truly Free is a brand I trust across multiple cleaning categories in our home, and their laundry detergent is no exception. The formula is plant-based, fragrance-free, and fully transparent — and the performance is genuinely strong across all load types including heavily soiled items.
What makes Truly Free stand out beyond the formula is their refill model. You purchase the container once and refill it going forward, which reduces plastic waste significantly over time and keeps the ongoing cost reasonable.
This is the detergent I reach for when I want confidence that a load is getting genuinely clean. It’s also the brand I recommend most often to people who are just starting to transition away from conventional detergents.
Any downsides? The refill system requires ordering ahead rather than picking something up locally. If you run out unexpectedly, you’ll need a backup — which is why 9 Elements or Charlie’s make good rotation partners.
Would I repurchase? Yes — consistently one of our top performers.
If you want the best overall performance with a low-waste system, this is the one I’d choose.
What I Wouldn’t Repurchase (And Why)
In the interest of honesty — not everything we’ve tried has made the cut.
- Tide and conventional detergents. Skin irritation, persistent synthetic fragrance, and headaches were our experience. The ingredient lists are opaque and the fragrance is designed to linger on fabric — which sounds appealing until you realize what’s creating it.
- Downy and conventional fabric softeners. Fabric softener works by coating your fabric with a layer of chemicals. That coating stays on your clothes and against your skin. We stopped using it and the skin irritation improved noticeably.
- Costco’s dye-free and “natural” options. Convenient and reasonably priced, but the performance wasn’t consistent for us. “Natural” on a label is a marketing term, not a standard — and these didn’t clean the way we needed them to.
What We Personally Use Right Now
We rotate between all three detergents on this list depending on what we have on hand and what we’re ordering at the time.
9 Elements is what we grab when we need something quickly from Target. Charlie’s is our bulk staple — best price through Azure and it lasts a long time. Truly Free is our go-to when we want the strongest performance and are staying on top of refill orders.
All three work. None of them have given us the skin irritation, headaches, or fragrance overload we experienced with conventional detergents. That alone made the switch worth it for us.
We’ve rotated through these over time — not all at once — which gave us a good sense of how each one performs in real life.

Where I’d Recommend Starting
If you’re making the switch for the first time, keep it simple.
Start with 9 Elements if you shop at Target — grab it on your next run and try it for a few weeks. It’s the lowest barrier to entry on this list and the performance is solid.
If you prefer to order online and want something with a longer track record in the natural cleaning space, Charlie’s Soap is the one I’d point you to first. The ingredient list is about as clean as it gets and the value over time is hard to argue with.
Either way — start with one, give it a fair run, and adjust from there. You don’t need to try all three at once.
Final Thoughts
Switching your laundry detergent is one of the most impactful low-toxin swaps you can make — and one of the simplest. The products exist, the performance is there, and the cost is comparable to what you’re probably already spending.
You don’t need to overhaul your entire routine at once. Start with the detergent. Let the rest follow naturally as things run out.
Progress over perfection — always.
