Identifying 5 Potential Health Hazards in Dishwashing Liquid Ingredients

Dishwashing liquid is a common household item that we are all familiar with. However, some manufacturers use unclear sources for dishwashing liquid ingredients to cut costs, which can be harmful to consumer health. Doctor Network will highlight five hazardous chemicals you should avoid when purchasing dishwashing liquid for your home.


How does low-quality dishwashing liquid affect health?

Low-quality dishwashing liquid can impact health in the following ways:

1. Chemical Residue

Low-quality dishwashing liquids often contain high levels of chemical residues such as foaming agents, colorants, and fragrances. Using dishwashing liquid with strong foaming agents or chemicals can cause irritation to the skin and digestive tract.

2. Allergenic Potential

Chemicals in dishwashing liquid can trigger allergic reactions, including itching, swelling, and redness, especially for individuals with sensitive skin or a history of allergies.

3. Toxins

Some dishwashing liquids may contain harmful substances like phosphates, water softeners, or rust inhibitors, contributing to environmental pollution when discharged into drains and water sources. This can impact both human health and natural ecosystems.

4. Digestive System Impact

Excessive use or low-quality dishwashing liquids can lead to digestive issues. Some products may cause discomfort, irritation, or diarrhea if directly in contact with the skin or utensils after washing.

To protect your health, consider using dishwashing liquids that are free from irritating or harmful chemicals. Additionally, always read product labels and follow usage instructions to avoid overuse and direct skin contact.


5 Dishwashing Liquid Ingredients Harmful to Health

1. Triclosan – Antibacterial Agent

Triclosan is a cleaning agent found in dishwashing liquids with antibacterial and antifungal properties. However, excessive use can impact human health, particularly the thyroid and digestive systems. Therefore, use Triclosan in appropriate amounts to ensure its antibacterial effect without harm.

2. Silicate Salt

Silicate is essential in dishwashing liquids for metal surface cleaning. However, individuals with sensitive skin, especially children, may experience irritation upon direct contact, even in low concentrations. Inhaling high concentrations may affect respiratory functions related to bronchi and lungs.

3. Ammonium Sulfate – dishwashing liquid ingredients

Sulfates, commonly found in shampoos, facial cleansers, and dishwashing liquids, help produce high foam and clean oil stains. Ammonium sulfate, similar to sulfuric acid, can irritate sensitive skin. Some manufacturers exceed permissible sulfate levels to enhance foaming and cleaning capabilities, potentially causing peeling, itching, and, more dangerously, accumulating in the body leading to cancer.

4. Sulfuric Acid

Dry, itchy, and cracked hands after dishwashing are common due to the presence of sulfuric acid in dishwashing liquids. While safe at low concentrations, individuals with sensitive skin, skin conditions, or children may experience irritation.

5. Formaldehyde – dishwashing liquid ingredients

According to health organizations, formaldehyde is a toxic chemical used in dishwashing liquid formulations. It poses health risks as the human body cannot eliminate formaldehyde. Despite its high disinfection properties, many dishwashing liquid manufacturers include it. It is also disguised under names like methanol, methyl aldehyde, and ethylene oxide. Formaldehyde is not only an irritant but also associated with a high risk of cancer.


Choosing Safe Dishwashing Liquids for Health

To find dishwashing liquids that are safe for health and the environment, consider products with the following characteristics:

No Harmful Chemicals

Limit the use of products containing harmful dishwashing liquid ingredients listed above. Read product labels carefully to ensure the absence of these components.

Choose Natural or Organic Products

Dishwashing liquids labeled as natural or organic are typically made from environmentally-friendly ingredients that are less likely to cause irritation.

“Green” or “Eco-Friendly” Labels

Look for products labeled as “green” or “eco-friendly” as these products often adhere to environmental and health protection standards.

Not Tested on Animals

If animal rights are a concern, choose products that are not tested on animals. This information is usually indicated on the label.

Specifically Designed for Dishwashers

If using a dishwasher, opt for dishwashing liquids specifically formulated for use in dishwashers, rather than using regular dishwashing liquids. They are designed for effective cleaning in dishwasher environments.

Non-Irritating Products

If you or someone in your family has sensitive skin or a history of allergies, choose products specifically designed to be non-irritating.

Read Reviews and Research

Before purchasing, read consumer reviews and conduct further research on dishwashing liquid ingredients to ensure both effectiveness and safety.
