Blueland tablets are formulated without several common harsh chemicals, but "non-toxic" is not how the company describes them

Blueland dishwasher tablets do not contain phosphates, chlorine, or dyes. The company lists the active ingredients as enzymes (protease, amylase, lipase), surfactants, and water softeners. These are standard cleaning agents found in most dishwasher detergents, not poisons—but standard does not mean non-toxic in the strict sense.

The term "non-toxic" has no legal definition for cleaning products. The U.S. Environmental Protection Agency does not certify dishwasher tablets as toxic or non-toxic. Blueland markets their tablets as "plant-derived" and "hypoallergenic," which describes the source of some ingredients and the absence of common irritants, but those claims are different from a toxicity statement. If you are looking at the tablet itself, the main safety concern is the same as with any dishwasher tablet: swallowing it can cause harm, especially in children.

Key Takeaways

  • Blueland tablets do not contain phosphates, chlorine, or synthetic dyes, which are ingredients some people prefer to avoid.
  • The active cleaning agents in Blueland tablets are enzymes and surfactants, which are common in most modern dishwasher detergents.
  • Blueland does not label their tablets as "non-toxic"—they use terms like "plant-derived" and "hypoallergenic" instead.
  • The main safety risk with any dishwasher tablet is accidental ingestion, which can cause mouth and throat irritation or more serious harm in young children.
  • If you have concerns about specific ingredients due to allergies or sensitivities, the product label and Blueland's website list all active components.

What chemicals Blueland tablets do and do not contain

Blueland tablets are formulated without phosphates, which were once standard in dishwasher detergents but are now restricted or banned in many U.S. states because they can contribute to water pollution. The tablets also do not contain chlorine bleach, optical brighteners, or synthetic dyes. These omissions are the main reason the company emphasizes a "cleaner" formula.

What the tablets do contain are enzymes—protease breaks down protein-based food residue, amylase breaks down starches, and lipase breaks down fats. These enzymes are derived from naturally occurring microorganisms and are used in nearly all modern dishwasher detergents, including major brands. Blueland also includes surfactants, which are molecules that help water penetrate and lift away grease and food particles. The water-softening agents prevent mineral buildup on dishes and inside the machine.

None of these ingredients are inherently dangerous at the concentrations used in a dishwasher tablet. The risk comes from concentration and route of exposure—a tablet in your mouth is very different from a tablet dissolved in a full dishwasher of water.

How Blueland tablets compare to standard dishwasher detergents

Most major dishwasher detergent brands—Cascade, Finish, Electrasol—use the same enzyme-based cleaning system as Blueland. The main differences are in what is left out. Blueland omits phosphates and chlorine, while some other brands include them. Blueland also does not use synthetic fragrances or dyes, whereas many conventional tablets do.

If you are sensitive to dyes or fragrances, Blueland tablets may cause fewer problems than a heavily scented or colored alternative. If you are concerned about phosphate runoff in waterways, Blueland avoids that ingredient. But if your concern is whether the tablet itself is poisonous or will harm you through normal use, the answer is the same across brands: the cleaning agents are safe when used as directed, and dangerous if swallowed.

What happens if someone swallows a Blueland tablet

Swallowing a dishwasher tablet—Blueland or any other brand—can cause mouth and throat irritation, nausea, vomiting, and abdominal pain. In young children, a single tablet can cause more severe symptoms. The concentrated enzymes and surfactants can irritate mucous membranes, and the tablet itself may cause choking or blockage if not fully dissolved.

If a child or adult swallows a Blueland tablet, call Poison Control at 1-800-222-1222 (in the U.S.) or your local emergency number. Do not induce vomiting. The Poison Control center will advise you based on the person's age, weight, and symptoms. Keep the tablet packaging or the ingredient list available when you call.

The best prevention is storage: keep tablets in their original container, out of reach of children and pets, in a cabinet or high shelf. Do not transfer them to food containers or leave them loose on the counter.

Reading the ingredient label and safety data

Blueland publishes a full ingredient list on their website and on the product packaging. The list includes the enzymes, surfactants, and water-softening compounds by name. If you have a known allergy or sensitivity to any of these—for example, some people react to certain enzyme types—you can check the label before purchase.

Blueland also provides a Safety Data Sheet (SDS), which is a technical document that lists hazards, first-aid measures, and storage requirements. You can request this from the company or sometimes find it on their website. The SDS will tell you the specific health hazards associated with the product and what to do in case of exposure.

If you are pregnant, nursing, or managing a health condition that makes you cautious about household chemicals, reading the SDS and discussing it with your doctor is a reasonable step. The SDS is not marketing material—it is a factual safety document required by law.

Safer handling and storage practices

Store Blueland tablets in a cool, dry place away from moisture. Humidity can cause the tablet to break down or stick together. Keep them in the original packaging, which is designed to protect the tablet and clearly label the contents. Do not store them in a bathroom cabinet where steam from the shower can reach them, and do not keep them under the sink where they might be near cleaning supplies or food.

When loading the dishwasher, place the tablet in the detergent dispenser—do not drop it loose into the machine. This ensures the tablet dissolves at the right time in the wash cycle and reduces the chance of residue on dishes. Wash your hands after handling the tablet, especially before eating or touching your face.

If you have young children or pets in the home, consider a locking cabinet or a high shelf that is genuinely out of reach. Tablets are attractive to children because they look like candy, so visibility and accessibility matter more than the specific brand.

Why "plant-derived" and "non-toxic" are not the same thing

Blueland uses the phrase "plant-derived" to describe some of their ingredients, particularly the enzymes. This means the enzymes come from plants or plant-associated microorganisms rather than being synthesized in a lab. However, a substance being plant-derived does not make it non-toxic. Many plants contain compounds that are harmful in concentrated form—ricin from castor beans, cyanide from apple seeds, and oxalates from spinach are all plant-derived and can cause harm at certain doses.

The enzymes in Blueland tablets are safe because they are used at appropriate concentrations and are designed to break down in water. The same enzyme that is safe in a dishwasher tablet could theoretically cause irritation if you rubbed a concentrated form directly on your skin. Context and concentration matter more than origin.

When a company says a product is "plant-based" or "plant-derived," they are describing the source of the ingredient, not its safety profile. It is a marketing distinction, not a safety certification. If safety is your primary concern, focus on what the product does not contain (phosphates, chlorine) and what the SDS says about hazards, rather than on the origin of the ingredients.

Frequently Asked Questions

Are Blueland tablets safe to use around children and pets?

Blueland tablets are safe to use in a running dishwasher around children and pets, just as any dishwasher tablet is. The risk is accidental ingestion of the tablet itself, not exposure to the dissolved detergent in the wash water. Store the tablets out of reach, and the risk is minimal. If a child or pet swallows a tablet, contact Poison Control or your veterinarian when ready.

Do Blueland tablets leave residue on dishes?

Blueland tablets should dissolve completely in a normal dishwasher cycle and leave no residue on clean dishes. If you notice white or cloudy residue, it is usually mineral buildup from hard water, not the tablet itself. Running a rinse aid or using a water softening additive can help. If residue appears only with Blueland tablets and not with other brands, contact the company for troubleshooting.

Can I use Blueland tablets if I have sensitive skin?

Blueland tablets do not contain synthetic dyes or fragrances, which are common irritants. If you have sensitive skin, the main exposure risk is handling the tablet itself—wash your hands after loading the dishwasher. The dissolved detergent in the wash water should not contact your skin during normal use. If you have a known allergy to enzymes or surfactants, check the ingredient list or SDS before use.

What makes Blueland tablets different from phosphate-free tablets from other brands?

Many dishwasher tablets sold in the U.S. are now phosphate-free because of state regulations. Blueland's main distinction is the absence of chlorine, synthetic dyes, and fragrances. The core cleaning agents—enzymes and surfactants—are similar across brands. The difference is in what is omitted, not in a fundamentally different cleaning technology.

Is it safe to touch a Blueland tablet with bare hands?

Brief contact with a tablet is safe. Wash your hands afterward, especially before eating or touching your face. Do not hold a tablet in your mouth or chew it. If you have very sensitive skin or dermatitis, you might prefer to use the dispenser rather than handling the tablet directly, but occasional contact is not harmful.
