The Top 5 Toxic Ingredients to Avoid in Soap

The Top 5 Toxic Ingredients to Avoid in Soap

Like brushing your teeth and washing your hair, bathing has become such a routine part of our lives that we don’t often pay attention to what’s actually in the soaps and body wash products that we use. But we should.

Traditional soaps are often full of toxic, dangerous chemicals that penetrate the skin and cause serious health conditions, even as they wash away dirt. But with so many options out there, how can you choose the best soap for you and your family?

Knowing what ingredients to avoid is the first step in choosing the right soap, and we’re here to help with that. Take a look at the five most harmful ingredients in traditional soap, plus our pick for soaps to help you get clean with clean ingredients.


Parabens are chemicals that are used to preserve cosmetics and personal care products, the same way chemical preservatives are used to keep foods from spoiling while they sit on store shelves. Because widespread paraben use is still a relatively modern occurrence, we don’t have definitive scientific research on how it impacts the body. There is, however, a 2004 study that found traces of intact parabens in the breast tissue of women. 

While the study didn’t link the existence of the parabens to an increased incidence of breast cancer, it does reveal the chemicals’ ability to penetrate the skin and remain in the body unaltered by metabolism. Additionally, according to the Environmental Working Group, parabens can “act like the hormone estrogen in the body and disrupt the normal function of hormone systems.”


One of the best ways to avoid products with unsafe ingredients is to check ingredient labels for known toxins. Sometimes, however, that approach doesn’t work. Because the FDA doesn’t require cosmetic manufacturers to list the specific ingredients that are used to create their product’s scent, the word “fragrance” is often a convenient hiding place for some pretty toxic chemicals. 

Researchers found that the fragrances of up to 100% of cosmetic products contained known allergens. Phthalates are a group of chemicals that are used as a solvent and fixative in fragrances, and they have been shown to cause damage to the liver, kidneys, lungs, and reproductive system, including the still-developing testes of male babies in utero.

1, 4-Dioxane

Like the compounds that make up your favorite soap’s scent, you probably also won’t find 1, 4-Dioxane on any ingredient labels. 1, 4-Dioxane is found in soaps and other sudsy products, and it is created when common ingredients are mixed together. 1, 4-Dioxane is a byproduct of this process — not a standalone ingredient — which explains why the FDA doesn’t require that it be listed on labels.

The Environmental Working Group (EWG) notes that while 1, 4-Dioxane can easily be removed from products prior to packaging, it remains in up to 46% of personal care products on the market. This is a critical issue, as the EWG considers 1, 4-Dioxane highly hazardous. Even short term exposure to the chemical can cause irritation of the eyes, nose, and throat, as well as kidney and liver disease. Long term exposure can cause cancer, and 1, 4-Dioxane is also known to pass through a mother’s breast milk.

Sodium Lauryl Sulfate (SLS)

Whether they’re washing their hands or their body, many people equate the efficacy of soap to the amount of lather it generates. Unfortunately, all of those suds come at a cost. Sodium Lauryl Sulfate, also known as SLS, is the ingredient added to soap to make it lather, and according to the EWG’s Cosmetics Database, it’s highly toxic. SLS carries a high concern for irritation of the skin, eyes, and lungs, as well as moderate concern for organ system toxicity.


In September 2016, the FDA banned triclosan, an antibacterial and antifungal ingredient used as a preservative in personal care products. The chemical has been found to negatively impact the immune system and cardiovascular function, while also potentially triggering an increase in allergy and asthma symptoms, antibiotic and antimicrobial resistance, and lower testosterone levels (to only name a few side effects).

Unfortunately, the FDA ban didn’t eliminate these risks. The ingredients found in antibacterial soaps place the products in the same category as over-the-counter drugs, so antibacterial soaps are regulated by the FDA. Traditional soaps, however, are not.

Even after the antibacterial soap ban on triclosan, it is still found in 2,000 or more products. And because of its frequent use in personal care products, research estimates that up to 75% of Americans are currently exposed to this dangerous chemical

The Best Safe, All-Natural Soap

At Bend Soap Company, we craft all-natural, hypoallergenic soaps that are free of toxic ingredients but also completely effective in delivering a deep, moisturizing clean.

Our original Unscented Goat Milk Soap is made with just four ingredients: fresh goat milk, coconut oil, olive oil, and sustainably sourced red palm oil. These ingredients nourish the skin with vitamins and minerals leaving it soft and supple with no danger of irritation or worse. It’s even safe for newborns!

We also have more than a dozen scented varieties that are free of dangerous, mysterious “fragrances.” Instead, they’re made with high-quality essential oils like geranium rose, tea tree, and lavender.

Back to You

Lathering up in the bath or shower shouldn’t put you at risk for harmful health conditions like skin rashes or eye irritation. Ditch the traditional soaps that are filled with “dirty” ingredients like parabens, SLS, and triclosan, and opt, instead, for a more natural option. Goat milk soap provides a deep clean that will also leave your skin soft, supple, and nourished.

In addition to the ingredients listed, coconut oil is especially comedogenic (pore clogging) for sensitive and acne-probe skin and can actually worsen acne in certain individuals. Just a tip from experience.


This is very informative, and also anxiety provoking. If an ingredient is a by-product if mixing other ingredients, we can’t know if it’s in there or not. Also, while I can control what I use at home, there is still a need to wash our hands in public places where we can’t control what type of soap is available, and it’s not practical to carry around our own soap. It’s frustrating that chemicals banned in other countries (supposedly) are still widely used in the US, despite having government agencies that are supposed to be in the business of protecting us. I’m sure it’s all in the name of making more money.


Great information!
