Isopropyl Alcohol, commonly referred to as IPA or rubbing alcohol, is a versatile solvent and disinfectant. At a concentration of 99%, it offers near-maximal purity, optimizing its solvent properties and making it a popular choice in diverse applications.

Chemical Characteristics

Isopropyl Alcohol, with the chemical formula C3H8O, is a flammable, colorless liquid with a strong odor. Its high concentration at 99% ensures minimal presence of water, which enhances its solvent efficacy and reduces its potential for microbial growth.

Appearance and Odor

Being a clear, colorless liquid, Isopropyl Alcohol 99% has a pronounced, recognizable odor that can be easily identified during its use.

Evaporation Rate

The 99% concentration of Isopropyl Alcohol ensures a rapid evaporation rate, making it ideal for tasks where quick drying is essential, such as in cleaning electronics or glass surfaces.


Thanks to its impressive purity and solvent capabilities, Isopropyl Alcohol 99% is widely adopted in various industries and applications.

Electronics and Cleaning

Due to its fast-evaporation and lack of water content, it is extensively used in electronics for cleaning and degreasing, ensuring no water residue is left behind.

Pharmaceuticals and Cosmetics

In pharmaceuticals, it acts as a solvent in the production of many drugs. In cosmetics, it’s used in the formulation of various products, including skin cleansers and makeup removers.


While its disinfection capabilities are pronounced, it’s best used in combination with water to enhance its microbicidal activity. Still, its high concentration offers benefits in specific disinfection scenarios.

Handling and Storage

Given the nature of Isopropyl Alcohol, appropriate precautions are paramount during handling and storage.

Safety Measures

Wearing protective equipment, such as gloves and safety goggles, is essential. Due to its flammable nature, it should be kept away from open flames or sparks. Proper ventilation is crucial during use to prevent inhalation and potential respiratory irritations.

Storage Recommendations

Store in a cool, dry place, away from direct sunlight or heat sources. Tightly sealed containers are essential to maintain its purity and to prevent evaporation or contamination.


Isopropyl Alcohol 99%, with its outstanding purity and versatile applications, remains a cornerstone in a myriad of industries. Ensuring proper handling and storage not only extends its shelf life but also guarantees its efficacy in various tasks.
