Is Dishwasher Detergent Residue Safe for Your Family

Dishwasher detergent residue can be a concern for many families, especially those with young children or pets. The residue can be a breeding ground for bacteria and germs.

Research shows that dishwasher detergent residue can contain high levels of sodium lauryl sulfate, a known skin irritant.

In fact, the American Academy of Pediatrics recommends avoiding exposure to sodium lauryl sulfate for children under the age of three.

This is especially concerning when children put their hands in their mouths after touching dishes that have been washed with residue containing detergent.

Commercial dishwashers can be a breeding ground for toxic residue, particularly when it comes to rinse agents containing alcohol ethoxylates. These chemicals can damage the protective layer in the gut and lead to chronic diseases.

In many commercial dishwashers, there's no additional wash cycle to remove the remaining rinse aid, allowing potentially toxic substances to remain on dishes and dry in place. This means that every time you use those dishes, you're exposing yourself to a higher risk of gut damage.

High doses of rinse agents can destroy intestinal epithelial cells, while lower doses increase its permeability, making it easier for toxins to enter the body. This can trigger inflammatory responses and potentially lead to a range of chronic diseases.

Detergent residue on dishes may harm gut health. Research has shown that the residue from commercial dishwashers can contain toxic substances that remain on dishes even after washing and drying.

A study conducted by researchers at the Swiss Institute of Allergy and Asthma Research found that the ingredient alcohol ethoxylate in commercial rinse agents can severely damage the gastrointestinal tract.

In a commercial dishwasher, a round of hot water and detergent circulates for 60 seconds at high pressure, followed by another 60-second washing and drying cycle in which water and a rinse agent are used. This can leave behind potentially toxic substances that dry in place on the dishes.

The researchers found that high doses of rinse agents destroyed the intestinal epithelial cells, while lower doses increased its permeability. They also observed the activation of several genes and cell signaling proteins that could trigger inflammatory responses.

A component of the rinse agent – alcohol ethoxylates – was found to be responsible for this reaction. The effect of alcohol ethoxylates on intestinal cells could plausibly trigger a number of inflammatory diseases in humans.

It's especially alarming that in many appliances, there's no additional wash cycle to remove the remaining rinse aid. This means that potentially toxic substances remain on the dishes, where they then dry in place.

The researchers identified the culprit behind the damage to be alcohol ethoxylates, which are often used in detergents and surface cleaners to help displace debris from household objects. However, prior research has found alcohol ethoxylates to be non-toxic to human cells and no evidence has been found to suggest they are carcinogenic or mutagenic.

The greatest damage on gut cells came from alcohol ethoxylates in rinse aid at dilutions of 1:10,000. Domestic dishwashers tend to use a little more water and longer washing cycles with dilution factors calculated at 1:80,000, but the researchers are more concerned with short-cycle commercial dishwashers that have dilution factors as small as 1:2,000.

Videos about dishwasher detergent safety often sensationalize the issue, but it's essential to look beyond the headlines.

The creators of these videos typically have an objective, whether it's to sell a product, course, or lifestyle, which can influence the information presented.

The source material, including academic papers, may have sensational headlines to catch attention, but it's crucial to examine the content to understand the actual risk.

Videos often feature out-of-context charts and quotations that don't represent human exposure when used as directed.

The paper in question explores specific dilution ratios, which are significantly higher than concentrations we'd be exposed to in a typical home setting.

For example, one experiment had a dilution ratio over 300 times more concentrated than a typical use setting.

Even the highest dilution factor explored in the study was 2 times more concentrated than a typical use case.

To put this into perspective, here are some key dilution ratios from the study:

Residue from dishwashers can seriously damage the protective layer in the gut and lead to chronic diseases.

Alcohol ethoxylate, an ingredient in commercial rinse agents, can severely damage the gastrointestinal tract.

Commercial dishwashers can leave behind residue from rinse agents, which can dry on dishes and potentially enter the gut when used again.

This residue can trigger inflammatory responses and even destroy the intestinal epithelial cells.

High doses of rinse agents can destroy intestinal epithelial cells, while lower doses increase its permeability.

The researchers focused on the epithelial layer of cells in the gut, which lines the intestinal tract and controls the movement of elements that can enter the body.

A breach in this barrier is associated with a myriad of health conditions such as food allergies, gastritis, diabetes, obesity, cirrhosis of the liver, rheumatoid arthritis, multiple sclerosis, autism spectrum disorders, chronic depression, and Alzheimer's disease.

The study analyzed the effect of different ratios of rinsing agents on human intestinal organoids and intestinal cells on microchips.

The substances were diluted in a ratio that mimicked the quantity that would be present on dry dishes (1:10,000 to 1:40,000).

The researchers used a newly developed technology for their study—human intestinal organoids and intestinal cells on microchips.

The tissue forms a three-dimensional clump of cells that is very similar to the intestinal epithelium in humans.

One component of the rinse agent—alcohol ethoxylates—was found to be responsible for the reaction.

According to the researchers, the effect that they found could mark the beginning of the destruction of the gut's epithelial layer and trigger the onset of many chronic diseases.

It is essential to inform the public about this risk since alcohol ethoxylates seem to be commonly used in commercial dishwashers.

The videos making sensational claims about dishwasher detergent residue often use out-of-context charts and quotations that are accurate but not representative of human exposure when used as directed.

These videos intentionally invoke fear, suggesting that everyday products like dishwasher detergent are causing sickness, and that natural products or more time-intensive actions are the only way to remain safe and healthy.

The paper that these videos are referencing actually looks at specific dilution ratios that are significantly higher than any concentration we'd be exposed to when using products as designed and directed in a home setting.

In fact, the dilution ratios presented in the paper are often more than 300 times more concentrated than what we'd be exposed to in a typical use setting.

Even the highest dilution factor explored in the paper was 2 times more concentrated than a typical use case, which raises important questions about the validity of the claims being made.
