Acute ethanol intoxication after consumption of hairspray

Abstract

A 61-year-old woman with a history of alcohol dependence came to the emergency department with ethanol intoxication. Her serum ethanol concentration was 322 mg/dl. When questioned, she admitted to consuming a 14-oz bottle of hairspray mixed with water because of its denatured alcohol content. The woman had used nonbeverage sources of alcohol on a regular basis for a number of years after learning of the practice from fellow attendees of Alcoholics Anonymous meetings. Her primary reason for this behavior was to hide her continued alcohol abuse from her family. She consumed hairspray that contained 50% denatured alcohol by volume; the amount she ingested was equal to 7 fluid oz of ethanol, the equivalent of 14 1.25-oz shots of 80-proof liquor. Her serum ethanol concentration was consistent with that predicted by pharmacokinetic equations based on the consumption of one bottle of hairspray. The hairspray product contained specially denatured alcohol 40-B, which consists of ethanol and small quantities of t-butyl alcohol and denatonium benzoate. Ethanol is the substance of primary toxicologic concern. Clinicians need to be aware that numerous nonbeverage sources of alcohol exist and should be considered when a patient presents with acute intoxication. The source and its components should be identified as soon as possible in order to assess other potential toxicities.
