Deodorant and antiperspirant products are designed for topical use on the skin, not for ingestion. While accidental ingestion, often involving small amounts by children, is a common call to poison control centers, these products contain chemicals that can be irritating or toxic if consumed in larger quantities. The overall severity of the reaction depends heavily on the specific ingredients and the total amount swallowed. Understanding the difference in composition between deodorants and antiperspirants is the first step in assessing the potential hazard, as their components pose distinct risks.
Key Ingredients and Potential Hazard Levels
The potential for harm from ingestion is directly related to the chemicals used in the product’s formulation. Antiperspirants contain aluminum compounds, such as aluminum chlorohydrate or aluminum zirconium, which function by temporarily blocking sweat ducts. While aluminum compounds are generally considered to have a low order of toxicity, they can be highly irritating to the lining of the mouth, throat, and stomach.
Deodorants, which only mask odor, often rely on higher concentrations of alcohol (ethanol) and fragrances. Ethanol in gels or sprays can be a significant concern if large amounts are consumed, potentially leading to central nervous system depression or intoxication. Propylene glycol is another common ingredient, and while it has a low toxicity profile, ingesting excessive amounts can increase the acid level in the body.
Fragrances and essential oils are potent irritants that can cause a burning sensation in the mouth and throat upon contact. The waxy or solid base of stick deodorants is largely non-toxic but can cause diarrhea or intestinal discomfort due to its non-digestible nature. The risk of severe toxicity is generally low for small, accidental ingestions of most solid products, but it increases substantially with the consumption of high-alcohol liquids or sprays.
Recognizing Symptoms of Ingestion
The immediate and most common symptoms following ingestion are typically centered in the gastrointestinal tract due to the irritating nature of the ingredients. An individual may experience a burning sensation or irritation in the mouth and throat right after swallowing. This irritation is frequently followed by nausea, stomach pain, and vomiting as the chemicals reach the stomach lining.
Swallowing the waxy base of a stick product often leads to minor discomfort and can result in loose stools or diarrhea, as the body struggles to process the non-food components. Aspiration is a specific risk, especially with aerosol sprays, where droplets are accidentally inhaled into the lungs. This can trigger coughing, choking, or more serious respiratory symptoms.
More severe effects can occur if a product with a high concentration of ethanol is consumed in a large volume. This can lead to central nervous system effects, including dizziness, drowsiness, confusion, or a state resembling alcohol intoxication. Although rare, any sign of decreased alertness, difficulty breathing, or persistent, severe vomiting suggests a serious reaction and requires immediate attention.
Immediate Response and Medical Guidance
The first step after any ingestion is to remove any remaining product from the mouth and rinse the area thoroughly with water. If the person is conscious and able to swallow, offering a small amount of water or milk can help dilute the product and soothe the irritated lining of the esophagus and stomach. Do not attempt to induce vomiting, as this can cause further irritation to the esophagus or increase the risk of aspiration into the lungs.
The most important action is to contact Poison Control immediately by calling the national hotline at 1-800-222-1222. These specialists are available 24/7 and can provide expert, specific guidance based on the ingredient list, the amount ingested, and the individual’s current symptoms. Be prepared to provide the exact product name, the approximate amount consumed, and the age and weight of the person involved.
Emergency medical care should be sought immediately by calling 911 or your local emergency number if the individual is experiencing severe symptoms. These symptoms include loss of consciousness, severe difficulty breathing, or relentless vomiting.
