Non-Toxic Laundry Detergent

Laundry detergents play a surprisingly central role in daily life. No matter where you live or what your routine looks like, you likely rely on detergent to clean your clothing, bedding, towels, and more. Unlike most cleaning supplies, laundry detergents cling to the very fabrics we wear and sleep on, making them a frequent source of chemical exposure inside the home.

Because we use laundry detergents so often, considering their toxicity levels helps you make more informed choices. By choosing safer options, you protect your skin, your health, and the environment. In this post, I’m excited to share a thorough roundup of laundry detergent ingredients to watch out for, as well as my favorite non-toxic detergent.

Over the years, I’ve spent countless hours reading laundry ingredient labels, contacting companies to learn about their sourcing and manufacturing practices, and testing various natural laundry detergent formulas. My goal? To bring you a recommendation that is not only safe but also effective.

Non-Toxic Laundry Detergent

Most laundry detergents promise cleanliness, but not all deliver it safely. In fact, many regular laundry detergents contain ingredients that can irritate sensitive skin, pollute waterways, and persist in the environment. In this post, I’ll explain what makes conventional detergents potentially toxic, which ingredients to avoid, and suggest a natural laundry detergent that works well in high-efficiency machines.

You’ll also discover what to look for if you have sensitive skin and want a detergent that cleans thoroughly without compromising safety or performance. By the end, you’ll feel confident selecting a non-toxic laundry detergent that protects your home, your health, and the planet.

Are Laundry Detergents Toxic?

Yes, most conventional laundry detergents include chemicals that raise valid health and environmental concerns. Manufacturers often prioritize performance and cost over ingredient safety. As a result, detergents may contain residues that irritate sensitive skin, disrupt hormones, or accumulate in waterways, harming aquatic life.

Next, since you regularly wear clothes washed in these detergents, exposure happens day after day. Although regulatory agencies set safety limits, the long-term effects of low-level chemical exposure from laundry detergents remain understudied. Choosing a non-toxic laundry detergent reduces your overall chemical burden and supports healthier living.

Why Is Laundry Detergent Toxic?

To begin, conventional laundry detergents rely on synthetic chemicals to clean, foam, deodorize, and brighten fabrics. Many of these ingredients lack comprehensive safety data or cause environmental harm. They can remain on fabrics even after rinsing, increasing the risk of allergic reactions and skin irritation, especially for those with sensitive skin.

Additionally, several ingredients serve mainly cosmetic roles, like adding artificial fragrance or brightening colors, rather than improving cleaning power. These unnecessary chemicals increase your exposure without offering meaningful benefits. Personally, I’d much rather my clothes smelled fresh because they’re truly clean, not because their odor has been covered up with artificial fragrance.

What Are The Toxic Ingredients In Laundry Detergent?

In this section, I’ve distilled years of research into a clear summary of the most common ingredients I recommend avoiding in laundry detergents. Many of these substances either harm the environment, lack reliable safety data, or, despite their risks, remain legally allowed in formulations.

Optical Brighteners

First, optical brighteners don’t clean clothes. Instead, they adhere to fabric and reflect light to make laundry look brighter and whiter. These fluorescent whitening agents don’t biodegrade and can persist in the environment, posing risks to aquatic life. Furthermore, the EPA Safer Choice program recommends avoiding them or using safer alternatives (source). A truly non-toxic laundry detergent uses no optical brighteners.

Ethoxylated Ingredients

Second, there is the category of ethoxylated ingredients. You can easily identify them by looking for ingredients labeled as “polysorbate” and “PEG” or ending in “-eth”.

More specifically, ethoxylated surfactants are made with ethylene oxide and may contain its residue in the final product. It is worrisome because ethylene oxide is carcinogenic and has developmental and reproductive concerns (source).

Not only that, ethoxylated ingredients can also contain 1,4-dioxane, a human carcinogen that forms as a contaminant during manufacturing. These ingredients help detergents foam and dissolve dirt, but they can also readily penetrate the skin (source). Since labels don’t disclose 1,4-dioxane, it’s best to avoid products with ethoxylated components if you want a safer natural laundry detergent.

Undisclosed Fragrance

Third, many laundry detergent manufacturers add synthetic or “natural” fragrances—a cocktail of undisclosed chemicals that often includes allergens, irritants, and hormone disruptors. You may have already noticed that these undisclosed scents can trigger skin reactions or respiratory issues. Learn more in my post about Natural Fragrance.

Next, some people in the non-toxic community assume that essential oils are always safe. However, even these sources of scent can cause allergic reactions in individuals sensitive to certain naturally occurring compounds. That said, many people tolerate essential oils in laundry detergent just fine—it’s simply something to be aware of.

When in doubt, I recommend choosing a fragrance-free detergent. This offers the safest option, particularly for children and anyone with sensitive skin.

Harsh Preservatives

Fourth, while the presence of preservatives is important in water-based detergents, many preservatives are undesirable. For example, benzisothiazolinone, methylchloroisothiazolinone, methylisothiazolinone, and octylisothiazolinone prevent microbial growth but can irritate skin and cause sensitization. Laundry detergents, especially liquids, frequently contain these chemicals, which potentially aggravate sensitive skin and cause rashes or itching with repeated exposure.

Polyvinyl Alcohol

Fifth, polyvinyl alcohol (PVA) is a water-soluble synthetic polymer commonly found in laundry pods and sheets. While it dissolves in water, it does not always biodegrade in natural environments, contributing to microplastic pollution. Because many “eco-friendly” pods use PVA, it’s essential to watch for it when seeking a truly natural laundry detergent.

Ingredients Lacking Safety Data

Lastly, recognize that many laundry detergent brands include chemicals with little to no safety data. For example, manufacturers use polyoxyalkylene substituted chromophore (blue) to make laundry appear cleaner, even though no safety data supports its use. This unnecessary ingredient adds potential exposure for people with sensitive skin or allergies.

Some brands also rely on vague ingredient lists or proprietary blends, listing broad categories like “surfactants” instead of naming specific ingredients. Often, companies that market themselves as “non-toxic” take this approach, perhaps hoping consumers will interpret a shorter, ambiguous list as a sign of safety. In reality, this lack of transparency makes it harder to evaluate the true safety of the product.

What Is A Non-Toxic Laundry Detergent?

Simply put, a non-toxic laundry detergent cleans effectively without using harmful or poorly studied chemicals. It relies on disclosed surfactants, mineral boosters like sodium carbonate (washing soda), and natural enzymes to help break down stains and dirt. These detergents skip optical brighteners, undisclosed fragrances, harsh preservatives, and ethoxylated ingredients.

Also, good natural laundry detergents perform well in high-efficiency washers, conserving water and energy. Whether fragrance-free or scented with essential oils, these options reduce your chemical exposure while delivering clean, fresh clothes.

What Is The Best Non-Toxic Laundry Detergent?

When selecting the best non-toxic laundry detergent, I focus on safety, transparency, environmental responsibility, and cleaning power. Among many options, one brand stands out as my top recommendation based on years of research and personal use, which I will discuss next.

Pure Haven Laundry Detergent

Without a doubt, my top non-toxic recommendation is Pure Haven Laundry Detergent. I use Pure Haven’s laundry detergent and trust this company completely. Specifically, Pure Haven manufactures their products in the USA facility that they own under some of the strictest safety standards in the industry. They carefully control every step of production to ensure ingredient quality, batch consistency, and full transparency—rare qualities in laundry detergents today.

Pure Haven’s formula excludes optical brighteners, fragrances, and ethoxylated ingredients. Next, it contains no harsh preservatives, such as benzisothiazolinone or methylchloroisothiazolinone.

Furthermore, this detergent uses a variety of natural enzymes to be tough on stains. It also contains sodium carbonate peroxide that helps naturally brighten clothing (goodbye dingy whites)! In my experience, these ingredients have completely satisfied my family’s needs. Whether washing out stains on my son’s clothing or removing sweat and odors from workout clothing, it has proven its effectiveness time and again.

Finally, Pure Haven’s laundry detergent performs well in hard water and is approved for high-efficiency washers.
