Isopropyl alcohol (IPA), also known as 2-propanol, is a versatile and effective cleaning agent that can be used for a variety of purposes. It is the active ingredient in many household cleaners and sanitizers, and it can also be used for personal hygiene, electronics, metal, plastic, glass and more. But what makes 2-propanol(cas67-63-0) 99% the ultimate solution for cleaning and disinfection? In this article, we will explore the benefits, uses and safety precautions of 2-propanol 99%, and how it compares to other concentrations of IPA.
Benefits of Isopropyl Alcohol 99%
Isopropyl alcohol 99% has several advantages over lower concentrations of IPA, such as 70% or 91%. Here are some of them:
- It is longer lasting. Isopropyl alcohol 99% does not contain water, which means it does not evaporate as quickly as lower concentrations. This makes it more economical and efficient, as you can use less product for the same results.
- It is more effective as a disinfectant. Isopropyl alcohol 99% is capable of killing 99.99% of germs, including bacteria, fungi and viruses. It can inactivate microbes by denaturing their proteins and disrupting their cell membranes. It is especially effective against lipophilic viruses, such as herpes, vaccinia and influenza.
- It is safer to use and store. Isopropyl alcohol 99% has a lower flammability risk than lower concentrations, as it requires a higher temperature to ignite. It also has a lower risk of freezing or developing mold or bacteria growth, as it does not contain water.
Uses of Isopropyl Alcohol 99%
Isopropyl alcohol 99% can be used for a wide range of cleaning and disinfection tasks, such as:
- Cleaning electronics. Isopropyl alcohol 99% can safely remove dust, dirt, grease and fingerprints from electrical contacts, audio or video tape heads, optical disc lenses, CPU heatsinks and more. It can also disinfect keyboards, mice, phones and other devices that are frequently touched.
- Cleaning metal, plastic and glass. Isopropyl alcohol 99% can dissolve oils and leave behind a streak-free shine on metal, plastic and glass surfaces. It can also disinfect tools, equipment, eyeglasses, jewelry and more.
- Cleaning personal hygiene items. Isopropyl alcohol 99% can sanitize items that come into contact with your skin or mucous membranes, such as razors, tweezers, scissors, thermometers, earbuds and more.
Safety Precautions of Isopropyl Alcohol 99%
While isopropyl alcohol 99% has many benefits and uses, it also has some drawbacks and risks that need to be considered. Here are some of them:
- It is not suitable for all surfaces. 2-propanol 99% can damage some materials that are sensitive to alcohol, such as rubber, cork, leather, acrylic and some plastics. It can also cause discoloration or fading on some fabrics and paints. Always test a small inconspicuous area before using isopropyl alcohol 99% on any surface.
- It is not suitable for all microbes. 2-propanol 99% is not effective against some hydrophilic viruses, such as hepatitis A and poliovirus. It is also not effective against bacterial spores. For these microbes, other disinfectants may be needed.
- It is not suitable for wounds or skin. 2-propanol 99% can cause skin irritation, dryness and cracking. It can also delay wound healing by destroying healthy tissue. For wounds or skin infections, other antiseptics may be needed.
- It is toxic if ingested or inhaled. Isopropyl alcohol 99% can cause nausea, vomiting, drowsiness, coma and even death if swallowed or breathed in large amounts. It can also cause eye irritation if splashed into the eyes. For these reasons, 2-propanol 99% should be kept out of reach of children and pets, and used in well-ventilated areas.
How to Use Isopropyl Alcohol 99%
To use 2-propanol 99% effectively and safely for cleaning and disinfection purposes, follow these steps:
- Wear gloves and eye protection to avoid skin and eye contact.
- Apply a small amount of isopropyl alcohol 99% to a clean cloth or cotton pad.
- Wipe the surface or item gently and thoroughly, making sure to cover all areas.
- Allow the surface or item to air dry completely before using or storing.
