The Difference Between Rubbing Alcohol and Drinking Alcohol: A Comprehensive Guide
Rubbing alcohol and drinking alcohol might seem similar at first glance – both are types of alcohol, after all. However, the differences are crucial, extending beyond just their intended use. Confusing the two can have serious health consequences. This guide will explore the key distinctions between these two types of alcohol.
What are the key differences between rubbing alcohol and drinking alcohol?
The primary difference lies in their chemical composition and intended use. Drinking alcohol, also known as ethanol (ethyl alcohol), is purified for consumption. Rubbing alcohol, on the other hand, is primarily isopropyl alcohol (isopropanol), although some formulations may contain ethanol as a secondary ingredient. This fundamental chemical difference dictates their vastly different properties and applications.
1. Chemical Composition:
-
Drinking Alcohol (Ethanol): This is the type of alcohol found in alcoholic beverages like beer, wine, and spirits. It's produced through the fermentation of grains, fruits, or other organic matter. Ethanol is relatively less toxic when consumed in moderation, although excessive consumption can lead to serious health problems.
-
Rubbing Alcohol (Isopropyl Alcohol): This is a synthetically produced alcohol, significantly more toxic than ethanol. Ingesting even small amounts of isopropyl alcohol can cause severe illness or death. It's used as an antiseptic and disinfectant due to its ability to kill bacteria and viruses.
2. Intended Use:
-
Drinking Alcohol: Consumed as a beverage, although it's crucial to emphasize responsible and moderate consumption due to its potential for addiction and health risks.
-
Rubbing Alcohol: Used topically for cleaning wounds, disinfecting surfaces, and reducing fever (through evaporation). It's never intended for internal consumption.
3. Toxicity:
-
Drinking Alcohol: While relatively less toxic compared to isopropyl alcohol, ethanol is still a toxic substance. Excessive consumption can lead to liver damage, heart disease, and other health issues.
-
Rubbing Alcohol: Extremely toxic when ingested. Even small amounts can cause nausea, vomiting, abdominal pain, central nervous system depression, and potentially death. It can also cause severe skin irritation and burns if applied liberally or left on the skin for extended periods.
4. Appearance and Odor:
While both may appear as clear liquids, their odors are distinct. Rubbing alcohol typically has a stronger, more pungent odor than drinking alcohol. This difference in scent helps distinguish the two.
5. Purity:
Drinking alcohol undergoes a purification process to remove impurities and make it suitable for consumption. Rubbing alcohol, however, is not purified to the same degree and may contain additives to enhance its antiseptic properties or to denature it, making it unfit to drink. These additives often contribute to the characteristic odor.
What happens if you drink rubbing alcohol?
Drinking rubbing alcohol can have extremely serious consequences, ranging from severe illness to death. Isopropyl alcohol is metabolized differently than ethanol, leading to the formation of highly toxic compounds in the body. Symptoms of isopropyl alcohol poisoning can include nausea, vomiting, abdominal pain, headache, dizziness, confusion, and even coma. Immediate medical attention is crucial if someone ingests rubbing alcohol.
Can you use drinking alcohol as a disinfectant?
While drinking alcohol does have some antiseptic properties, it's generally not recommended as a primary disinfectant. Its concentration in alcoholic beverages is typically too low to effectively kill many types of bacteria and viruses. Furthermore, using drinking alcohol for disinfection wastes a resource intended for consumption. Dedicated disinfectants are more effective and safer to use.
In conclusion, the differences between rubbing alcohol and drinking alcohol are significant and crucial for safety. Never confuse these two substances, and always handle rubbing alcohol with care, ensuring it's kept out of reach of children and pets. If you have any questions or concerns about alcohol consumption or the use of rubbing alcohol, consult a healthcare professional or pharmacist.
