It’s helpful of ironic that cleaning products are typically some of the least “clean” items in our homes. Laundry detergents in specific are heinous offenders, according to experts.

They’re often filled with chemicals that aren’t grand for humans or the environment.

So what, exactly, constitutes better-for-you laundry detergents? Here’s the thing: When it comes to cleaning products, finding the safest option isn’t always as simple as just reading labels.

As Well+Good Council member and non-toxic living expert Sophia Gushée points out, brands aren’t required to list every of their ingredients, so it’s hard to know for certain what’s really inside the bottle.

In general, numerous laundry detergents contain certain types of stabilizers, colors,preservatives, surfactants, solvents, and brightening agents linked to negative health effects. (Think respiratory issues, hormone disruption, skin allergies, and even cancer.) Other common laundry detergent ingredients, love phosphates, can create harmful algal blooms that disrupt the ocean ecosystem.

If there’s one thing Gushée always avoids, it’s “fragrance”—a vague, unregulated term that can actually hide numerous diverse chemicals—aromatic and not—under its umbrella.

“Fragrance can contain an unknown number of potentially threatening ingredients, some of which could contribute to cancer, reproductive and developmental toxicity, allergies, and skin irritation,” says Gushée, author of A to Z of D-Toxing: The Ultimate Guide to Reducing Our Toxic Exposures.

If this freaks you out, there are plenty of brands now making fragrance-free suds—or choosing to reveal exactly what’s in their fragrances—which makes that part of the equation, at least, a little easier to navigate. Bonus: They’re also grand laundry detergents for sensitive skin types, which can be especially triggered by scents.

Below are a few clean laundry detergents that score high marks for people and the planet, according to the guidelines established by the Environmental Working Group (EWG)’s Guide to Healthy Cleaning and the Environmental Protection Agency (EPA)’s Safer Choice standards.

They also rate highly for effectiveness, as far as online reviews go. Because let’s be honest, opening the washer to discover not-so-clean clothes is stressful—and stress isn’t exactly excellent for you either.


What helpful of scientific study was this?

This was a non-systematic review article. The authors referenced 44 papers that are relevant to the debate about whether enzymes added to detergent washing powders can cause skin reactions.

Three skin reactions were looked at: skin irritation, such as hand eczema; allergic reactions that could be detected by blood tests or by testing with patches of the product applied to the skin; or urticaria (hives), a more widespread allergic reaction within minutes of contact.

The researchers do not describe how they searched for relevant scientific literature, but collectively they own extensive experience in managing skin conditions. The article describes the historical background of these “biological” detergents which were first created by adding proteolytic (protein digesting) enzymes to synthetic detergents in the second half of the 20th century.

Other enzymes, including amylases (that break below starch) and lipases (that digest fats) own been added more recently.

The authors own described the published studies, the groups of people in whom the experiments were performed and the largely negative findings. Importantly, some of the studies were placebo-controlled and blinded (where the participants were unaware whether they had been exposed to detergents or not) and in some, the biological detergents were compared with ordinary detergents, which can themselves cause irritation.

Some studies were in children and some in adults. Some assessed the dangers of occupational exposure to the enzymes in workers who produced the powders.


What does the NHS Knowledge Service make of this study?

This review article written by experts in the field has described a selected body of research and may well reflect the current state of knowledge in the field.

However, some limitations to this type of publication should be considered:

  1. Non-systematic reviews, those that own not described their searching methods, may fail to detect some publications which could influence the overall conclusion. It is not certain that every studies own shown no effect of these biological powders.
  2. The quality of the individual studies in the article has not been assessed so the reader is unable to judge how dependable the individual study results are.

    The ability of researchers to control for hidden bias from the placebo effect or from the unequal selection of participants who took part in these trials would be particularly relevant for an appraisal.

In general, the message from this paper is likely to reflect the opinion of experts in the area and the authors’ call for practitioners to carefully glance for causes of eczema in order to come to a correct diagnosis, seems love excellent advice.

Where did the tale come from?

Dr David Basketter and colleagues from St Thomas’ Hospital, Nottingham University and St Mary’s Hospital carried out this research.

The funding for this study was not described, though conflicts of interest and the receipt of consultancy fees from Unilever were declared. It was published in the peer-reviewedBritish Journal of Dermatology.


What interpretations did the researchers draw from these results?

The researchers’ view is that healthcare professionals should avoid the “mythology” about enzyme-containing laundry products to explain rashes on adults, children or infants. Rather, they should glance more carefully for the true cause of eczema in order to come to a correct diagnosis.


What were the results of the study?

The main results reported by the researchers are that ”enzymes in laundry detergents are not a cause of skin irritation in practice [or] of skin allergy” and that “from first principles, enzymes may own the potential to cause urticaria, but there is no evidence, both occupationally and in consumers, that this actually occurs in practice”.
