Are Dishwasher Tablets Toxic

Dishwasher tablets are timely and quite handy to use, as it saves your time and effort you just have to put one in the dishwasher and the machine will do the rest.

Most people like to use dishwasher tablets instead of dishwashing liquid and pods because they think that they get dishes cleaner.

But the problem is the chemicals used in dishwasher tablets usually drain from the dishwasher along with the water.

And that ends up in water systems and the environment, so the question that comes to people’s minds is whether or not dishwasher tablets are eco-friendly.

Unfortunately, most dishwasher tablets are not eco-friendly as they contain chemicals that can cause harm to the environment. Some of the chemicals found in them have the potential to harm humans as well.

Let’s discuss dishwasher tablets in more detail with regard to eco-friendliness and decide whether dishwasher tablets are toxic or not.

Dishwasher tablets usually bottle up many chemical ingredients that are created to clean your dishes by breaking down food and grease and adding flare also.

The ingredient combines surfactants, enzymes, and bleaches that work jointly with water to get your dishes clean.

Surfactants are chemicals that are capable of reducing the surface tension of liquids, letting them spread more.

And when it comes to dishwasher tablets, surfactants let the water from the dishwasher as well as other cleaning agents spread more smoothly for a deeper clean.

For breaking down the food and grease they put enzymes which are protein-based chemicals. One particular example of an enzyme found in dishwasher tablets is the protease and amylase enzymes.

So a number of chemicals make up dishwasher tablets and they all work jointly to make the cleaning properties potent. There are some chemicals that are safer for the environment and humans also as compared to others.

Almost all the dishwasher tablets are either separately enveloped in plastic packaging or cloaked in a plastic film that is water-soluble.

The water-soluble film is built from polyvinyl alcohol plastic film. This type of film is prepared to melt in water so that you don’t have to take off the film before putting the tablet in the dishwasher.

Dishwasher tablets are not eco-friendly for a couple of reasons.

Are Dishwasher Tablets Toxic

Chemical Ingredients

The foremost reason is that some of the chemicals bases in them can ruin the environment when they divulge into the water and drain out of the dishwasher. Ingredients like citric acid and glycerin are ones that cause not much harm to the environment.

The Environmental Protection Agency (EPA) also advocates that cleaning products comprising nitrogen and phosphorus can negatively affect water quality.

This is quite crucial considering that the chemicals found in dishwasher tablets finish as water systems. Unnatural fragrances and perfumes used in cleaning products also influence air quality both indoors and outdoors.

The reason for this is they comprise volatile organic compounds, and volatile organic compounds are typically discharged as gases and have low water solubility.

We haven’t mentioned an all-inclusive list of chemicals that are based in dishwasher tablets that adversely affect the environment. But it just gives you an idea of the chemicals base in them that is bad for the environment.

Dishwasher Tablets and Microplastic

Microplastics are petite pieces of plastic or microbeads that are based on most cleaning and cosmetic products, and they may pose a threat to aquatic organisms as they flow through drains and into the ocean.

It’s not unusual for detergents like dishwasher tablets to comprise microplastic, particularly since microplastics are used as a scrubbing agent to help take off dirt and debris from dishes and other surfaces.

So you can say that a lot of dishwasher tablets do carry microplastics, but it differs and it all depends on the brand of tablets so it’s not fair to say that all dishwasher tablets contain microplastics.

Can we support Dishwasher Tablets?

Dishwasher tablets are not a justifiable product as they comprise a lot of synthetic chemicals and are wrapped in plastic. As we have discussed above that the plastic used to wrap dishwasher tablets comes from crude oil, which is a non-renewable resource.

But, it’s not defendable to make synthetic chemicals either, no matter whether chemicals are derived from natural sources. Creating synthetic chemicals is all about using methods that are distinct from what nature uses to make chemicals.

Usually, these ways involve making procedures that can hand out lots of energy being used. The energy used for making procedures typically comes from burning fossil fuels which are also non-renewable.

One more crucial thing to note here is that dishwasher tablets are a single-use product, and while there isn’t a kind of dish cleaning product that you can use regularly,

Dishwasher tablets don’t go as far as products like dishwashing liquid do. For this reason, makers have to produce more dishwasher tablets as people buy them regularly due to going through them more swiftly.

Are Dishwasher Tablets Toxic?

The ingredients based on dishwashing tablets are probably dangerous or toxic to humans. For instance, unnatural fragrances can cause skin and respiratory irritation and defile. But, these ingredients do not always adversely influence humans as long as the tablets are used as planned.

Some of the other ingredients, like enzymes as well as citric acid, sodium silicate, sodium carbonate, and sodium bicarbonate pose not much risk to the health of humans.

There are problems that may occur with your dishwasher because using dishwasher tablets is detergent buildup. This happens with any dish detergent, whether that is pods, tablet powder, or even liquid.

If you use this product in the wrong way or use too much of the product then Detergent buildup can happen. And this leads to chemicals based in the detergents not melting properly and leaving behind residue.

And most of the time that residue can block up the drain and other mechanical elements, causing draining problems in your dishwasher. And because of this, there are chances that your dishes may not be as clean as they should be.

To stop this, it’s always better for you to use the suggested amount of product on the packaging and that you add the product to the right location in the dishwasher so that it gets properly dispensed.

Can dishwasher pods make you sick?

They are made in a way that the surfactants in soap will leave a residue if not completely rinsed away. But they are not harmful and can’t make you sick.

Is dishwashing detergent toxic?

It depends on your usage if you wash your dishes thoroughly with water then it’s safe.  These detergents can cause chemical burns if they fall on your skin, or if they get into your eyes. They’re highly alkaline, so they are capable of dissolving many things, and that includes human tissue.

What is the least toxic dishwasher detergent?

There are many nontoxic dishwasher detergents but to name a few we can say pur home Detergent tablets, ecos. Dishwasher gel and pods and cleancult. Detergent tablets are among the best nontoxic dishwasher detergents.


As the Dishwasher tablets contain various chemicals that can be dangerous for the environment when they melt into the water supply we can say that they are not eco-friendly.

The problem is they are also not ecological or compostable, and most of them enclose microplastics in addition to being covered in a plastic film also.

If you want to clean your dishes in a more eco-friendly manner, then there are many types of dishwasher tablets that are better for the environment. Or, if possible make your own tablets at home or go for eco-friendly dishwashing pods or liquid as well.
