My child swallowed dishwashing detergent

What is an automatic dishwasher detergent?

Automatic dishwashing detergents (ADDs) are available in many forms: powder or granules, liquid or gel, tablets (such as powder blocks), and pods. ADDs have specific ingredients that differentiate them from hand dishwashing detergents. These include strong alkalis, corrosion inhibitors that protect the metallic parts of the dishwasher, and enzymes that break down food. They also contain perfumes that help mask food odors and foam suppressors so that excess foam does not interfere with the cleaning action.

How do automatic dishwasher detergents differ from hand dishwashing detergents?

ADDs and hand dishwashing detergents accomplish the same job but in different environments. ADDs are made to work inside a machine. They rely on the force of sprayed water to scrub dishes. Hand dishwashing detergents are made knowing there will be substantial skin contact as hands do the scrubbing. As a result, hand dishwashing detergents are milder. Using an ADD for hand dishwashing is an invitation to damage skin, while using a hand dishwashing detergent in an automatic dishwasher is an invitation to a foamy mess.

Is automatic dishwasher detergent toxic?

The amount of dishwasher detergent ingested is important in determining whether a person who is exposed to an ADD will have no symptoms, mild symptoms, or severe effects. The majority of exposures are unintentional and by children 5 years of age or younger. It is common for kids to get hold of an ADD from the dishwasher itself. An open dishwasher door, where the dispenser usually sits, is at a child’s eye level. Fortunately, most unintentional ingestions tend to be very small, probably because ADDs have strong, unpleasant tastes. A lick or taste is unlikely to cause anything beyond an icky taste in the mouth. Nausea and vomiting are very common after a sip or a swallow or two.

ADDs are alkaline and have a pH of at least 10. For perspective, a neutral pH—or the pH of water—is around 7. ADDs’ alkalinity gives them a corrosive action against food grime, but also makes them capable of causing tissue injury and burns. Liquid ADDs tend to cause more injury than powders and tablets. This is because their pH tends to be higher—sometimes as high as 13.

What happens if you swallow automatic dishwasher detergent? Is it harmful to your skin or eyes? 

ADDs can irritate the mouth, throat, and stomach, resulting in a bad taste, burning throat, nausea, or vomiting. Swallowing an ADD can also result in extreme outcomes, such as severe burns and swelling of the throat, esophagus (food pipe), and stomach. Someone might also choke when swallowing an ADD, causing some to slip into the airway, resulting in coughing, chest pain, wheezing, and shortness of breath.

If an ADD comes into contact with the eye, it can cause discomfort and pain, redness, tearing, and sometimes a scratch or burn on the surface of the eye. If left on the skin for a prolonged time, ADDs can cause skin burns of varying degrees, resulting in redness and pain, peeling, and blistering.

The duration of exposure contributes to the outcome. Don't let an ADD sit on your skin or in your eye. Time allows the product to penetrate the tissue and eat away at it. The longer the exposure, the more severe the injury.

My child swallowed dishwasher detergent. What should I do?

If someone has swallowed an ADD, do not make them vomit. Have them rinse their mouth with water by swishing and spitting a few times. If it just happened, offer sips of water to drink. This will help dilute the product in the stomach, making it less irritating. If an ADD product gets in the eye or on the skin, immediately rinse gently with cool or comfortable-temperature water.
