HOME & HEALTH UK
Most people assume their laundry detergent is safe—after all, it’s just soap, right?
Unfortunately, many popular brands are packed with hidden chemicals that don’t just wash out.
They can stay on your clothes and get absorbed into your skin.
Some of these chemicals even need ‘legal limits’ due to their toxicity.
In New York, for example, the state recently banned certain detergents containing high levels of 1,4-dioxane, a known carcinogen linked to liver and kidney damage.
Yet, in many places (including the UK), this same chemical is still allowed if it’s within the ‘legal limit’.
What’s Really in Your Detergent?
If you’re using a big-brand detergent, chances are you’re washing your clothes in a chemical cocktail that includes:
🛑 Hormone Disruptors (Phthalates) – Used to make scents last longer, but they’ve been linked to reduced sex drive, fertility issues, and thyroid dysfunction.
🛑 Carcinogens (1,4-Dioxane & DEA) – Classified carcinogens detected in many mainstream detergents.
🛑 Optical Brighteners – These don’t actually clean—they just coat fabrics to make clothes look whiter and have been shown to cause skin irritation.
🛑 Skin Irritants (DEA & Formaldehyde) – These can strip your skin barrier, trigger eczema flare-ups, and lead to chronic skin irritation.
How These Chemicals Impact Your Health
Because laundry detergent lingers on fabric, you’re being exposed to these chemicals 24/7—whether you’re wearing clothes, sleeping on sheets, or drying off with a towel.
Over time, this constant exposure can lead to:
Damaged Skin Barrier – Harsh detergents can strip the skin, making it more prone to irritation, breakouts, and even allowing toxins to enter the body more easily.
Respiratory Issues – Studies suggest breathing in detergent fumes over time can be as bad for your lungs as smoking a pack of cigarettes a day.
Allergies & Sensitivities – Many detergent chemicals act as hidden allergens, leading to itchy skin, rashes, sneezing, and even asthma attacks.
Higher Toxic Burden – Your body is already exposed to toxins from food, air pollution, and personal care products. Detergent chemicals compound this toxic load, making it harder for your body to detox naturally.
Reproductive Issues – Phthalates and benzene-based chemicals have been linked to lower fertility rates in both men and women.
Increased Risk of Certain Cancers – Carcinogens like 1,4-dioxane have been detected in multiple mainstream detergents, despite growing health concerns.
What to Look for in a Truly Non-Toxic Laundry Detergent
With more consumers becoming health-conscious, the market for safer, chemical-free detergents has grown.
But with so many options, how do you know what’s actually safe?
Here are the key things to look for when choosing a truly non-toxic detergent:
✅ Plant-Derived or Low-Impact Ingredients
These ingredients break down naturally, making them safer for both your health and the environment.
✅ Hormone-Friendly Fragrance
Choose ECHA-compliant detergents with no known hormone disruptors, or go fragrance-free for extra caution.
✅ Certifications & Ingredient Transparency
To avoid dodgy claims, look for third-party certifications that verify a detergent’s safety (e.g. dermatologically tested).
But with so many “non-toxic” options on the market, how do you know which ones actually work?

The Top 5 Non-Toxic Detergents That Actually Work

Score: 95/100
After putting 15 non-toxic laundry detergents through rigorous testing, Dip came out on top as the best overall choice.
We tested it against gravy, mud, sweat, and makeup stains, and it consistently delivered the best stain removal of all the detergents we tried.
And let’s not forget about that Fresh Linen scent - divine! Not too overpowering either.
One of the biggest advantages of Dip is how easy it is to use.
Unlike liquid detergents that spill, drip, and require measuring, Dip’s pre-measured sheets eliminate all the mess—you just tear one in half and toss it in.
It’s also the only detergent we tested with an ECHA-compliant fragrance, meaning it’s free from known hormone disruptors.
This is a major win for people who are health-conscious but still want a detergent that smells fresh.
On top of that, Dip is one of the most sustainable choices—it’s plastic-free, biodegradable, and carbon-neutral.
Most “eco-friendly” detergents still come in plastic bottles, but Dip eliminates waste entirely.

Why These Sheets Were Our Favourite
One of the biggest reasons Dip stood out above the rest was the fact that it’s a laundry sheet—something none of the other detergents we tested offered.
Being a sheet-based detergent gave it several unique advantages that made it the most practical, effective, and eco-friendly option on our list.
Firstly, Dip was the only detergent with a true 3-in-1 formula, meaning it works as a detergent, fabric conditioner, and stain remover in one.
None of the other detergents had this feature, which means with Dip, you don’t need to buy multiple products—saving both money and hassle.
Secondly, because these sheets are liquidless, they have a much higher concentration of active cleaning ingredients.
Over 80% of the formula is active ingredients, making them far more potent for stain removal than the liquid detergents we tested.
This made Dip particularly effective for spot cleaning—we found that simply tearing off a small piece, adding water, and scrubbing worked wonders on tough stains like makeup, grease, and mud.
Another huge advantage of being liquid-free is how easy and mess-free the sheets are to use.
With every single liquid detergent we tested, we dealt with spills, over-pouring, or drips down the bottle.
In contrast, Dip’s sheets required zero measuring—all we had to do was tear a sheet in half and drop it in the drum.
This made it by far the most convenient detergent we tested.
From a health and safety standpoint, Dip was also one of the cleanest and most transparent brands we tested.
It was one of the only detergents to be fully compliant with the ECHA hormone disruptor list, meaning its formula contained no known endocrine-disrupting chemicals.
Additionally, Dip was the only brand that provided full transparency on its fragrance ingredients upfront—whereas with other brands, we had to contact customer support just to get a full ingredient breakdown.
Eco-friendliness was another major factor that set Dip apart.
Out of all the detergents we tested, it was the only one to come in both plastic-free AND compostable packaging.
While other brands claimed to be “eco-friendly,” they still used plastic bottles that had to be recycled—which, depending on local facilities, often still end up in landfills.
With Dip, there’s zero plastic waste.
And finally, Dip was also the most flexible option in terms of cost and convenience.
While some non-toxic detergents were significantly more expensive per wash, Dip offers subscription options that not only make it more affordable but also ensure you never run out.
This allowed it to compete on price while still being the best overall choice in terms of cleaning power, health safety, ease of use, and sustainability.
For all these reasons, Dip was our clear #1 pick.

Faith in Nature is a well-known brand in the natural cleaning space, so we had high expectations going into this test.
Right away, we loved the fresh, herbal scent of aloe vera and rosemary—it was one of the best-smelling detergents we tested, offering a natural fragrance without being overwhelming.
In terms of cleaning power, it handled most stains well—it had no trouble lifting baby food, tomato puree, coffee, and even red wine from cotton fabrics.
However, we found that mud and grass stains were a challenge, often requiring an extra pre-treatment step to fully remove them.
One of the biggest selling points of Faith in Nature is its bulk refill system, which is both cost-effective and eco-friendly.
However, the 20L bottle is quite large and heavy, making it a bit tricky to handle.
Pouring directly into the washing machine drawer was messy, and even refilling a smaller bottle wasn’t the easiest task.
While it does reduce plastic waste in the long run, the container itself is still made of plastic, meaning it’s not completely plastic-free like some of the other options we tested.

Ecover has been a trusted name in eco-friendly cleaning for years, so we were excited to put their Bio Laundry Liquid to the test.
It delivered strong overall cleaning power, removing almost 90% of stains, and did an exceptional job on baby food and sebum (the body oil that contributes to acne and greasy stains).
One of Ecover’s standout qualities was its ability to retain colour vibrancy.
After multiple washes, fabrics showed minimal fading, and white clothes came out looking bright and fresh.
For those who want a detergent that keeps clothes looking newer for longer, Ecover performed well in this area.
However, it wasn’t perfect—tea stains were a challenge, requiring extra effort or a pre-treatment step.
Another drawback was the plastic packaging—unlike some of the other detergents on our list, Ecover still relies on plastic bottles, which can end up in landfill even when recycled.
The lack of a handle also made it a bit difficult to pour, especially when full.

Smol is a popular choice for those looking for a more sustainable, plastic-free laundry detergent, and we were keen to see how it performed.
Performance-wise, Smol handled everyday stains well, with over 80% of stains lifting from our test fabrics. It did a great job on coffee, foundation, and baby food, and testers noted that whites stayed bright even after multiple washes.
However, it struggled a bit with tea stains—one of the biggest problem areas for multiple detergents we tested.
There was also some noticeable fading in colored fabrics over time, which was a downside.
One thing we liked was Smol’s stain gel, which performed well on common food and drink stains like baby food, sauces, and blood.
The subscription model is a double-edged sword—while it’s incredibly convenient for those who like automatic deliveries, some people might prefer to purchase detergent on their own schedule.
If you’re someone who prefers to buy in bulk or grab a detergent when you need it, Smol’s system may feel restrictive.

Method is a well-known eco-friendly cleaning brand, so we were curious to see how their Concentrated Bio Laundry Liquid performed.
Right off the bat, we liked the range of fragrance options—we tested the Peony Blush scent, which was pleasant and fresh without being overpowering.
However, we did note that Method’s fragrances contain synthetic perfumes, making it not entirely plant-based like some of the other detergents we tested.
When it came to cleaning power, Method delivered solid results, removing 90% of stains from our test fabrics.
It handled most everyday stains well, though it struggled with tea and foundation residue—two of the most stubborn stains across our testing.
One area where Method really impressed us was color retention.
Many bio detergents can be harsh on colors, but we saw minimal fading, even after multiple washes.
It also performed well on nylon whites, though we did notice some slight greying on white cotton and polycotton fabrics over time.
The biggest downside was the packaging design.
While the bottle looks sleek, it’s bulky and lacks a handle, making it harder to pour accurately—especially for those who prefer precise measuring without spills.
