What is the Difference Between Isopropyl and Rubbing Alcohol?
🆚 Go to Comparative Table 🆚Isopropyl alcohol and rubbing alcohol are not the same, despite having similar properties and uses. The main difference between them lies in their concentration:
- Isopropyl Alcohol: This is pure alcohol with a concentration of 100%. It is colorless, with a sharp odor, and is widely used as a disinfectant in various industries, including hospitals and pharmaceuticals. Isopropyl alcohol is not suitable for home use due to its high concentration.
- Rubbing Alcohol: This is a mixture of isopropyl alcohol and water, containing between 68% and 72% alcohol by volume. The remaining volume consists of water, color additives, oils, and denaturants. Rubbing alcohol may also contain methyl salicylate, which helps relieve aches and pains. It is commonly used as a disinfectant and for other at-home applications.
Both isopropyl and rubbing alcohol are antibacterial and antiseptic, and they share similar properties. However, they are not interchangeable and should not be used in the same ways. For example, undiluted isopropyl alcohol is too hazardous to use as a disinfectant for the skin or home, while rubbing alcohol is specifically formulated for such purposes.
Comparative Table: Isopropyl vs Rubbing Alcohol
The main difference between isopropyl alcohol and rubbing alcohol lies in their composition and concentration. Here is a comparison table highlighting their differences:
Property | Isopropyl Alcohol | Rubbing Alcohol |
---|---|---|
Definition | Isopropyl alcohol is a pure, colorless alcohol with a musty, sharp odor. | Rubbing alcohol is a mixture of isopropyl alcohol and water, sometimes containing additional ingredients. |
Concentration | The concentration of isopropyl alcohol is 100%. | The concentration of rubbing alcohol is less than 100% due to the addition of water. |
Uses | Isopropyl alcohol is commonly used as a solvent, cleaning agent, astringent, and disinfectant. | Rubbing alcohol is mainly used as an antiseptic for external use only. |
Side Effects | Undiluted isopropyl alcohol is too hazardous for home use and can cause irritation when applied to the skin. | Rubbing alcohol, when used as directed, is generally safe for at-home use. |
In summary, while isopropyl alcohol is a pure, undiluted alcohol, rubbing alcohol is a mixture of isopropyl alcohol and water with additional ingredients. Both have antibacterial and antiseptic properties, but they differ in concentration and intended use.
