At a Glance

Isopropyl alcohol and rubbing alcohol are quite similar but they are not the same. In this blog, we’ll delve into the key differences.

Is isopropyl alcohol the same as rubbing alcohol?

Isopropyl alcohol is an unadulterated compound and rubbing alcohol is a mishmash that generally has isopropyl alcohol with other ingredients. Household disinfectants, cleaning agents, and first aid solutions are the substances that include isopropyl and rubbing alcohol. It is common for a lot of people to ask, “Is isopropyl alcohol the same as rubbing alcohol?” Well, to answer the question, they are of the same type, but they are not the same thing. Applications and user instructions for usage are different, as their composition is not the same. 

In the following article, we will look at the dissimilarities, the uses, and the safety instructions of isopropyl alcohol and rubbing alcohol. Moreover, we will help you to locate where to buy isopropyl alcohol and rubbing alcohol.

What is Isopropyl Alcohol?

Isopropyl alcohol, often referred to as 2-propanol or IPA, is an adaptable and frequently used chemical substance that is clear and colorless, highly flammable, and has a strong and distinctive smell. In its chemical structure, as a secondary alcohol unit, it has a chemical formula C₃H₈O and it is noted for its efficacy in different tasks because of the strong solvent ability it possesses.

Properties of Isopropyl Alcohol

• • Chemical Formula: 

Isopropyl alcohol is one of the substances described by a chemical formula, e.g., C₃H₈O. It consists of three carbon (C) atoms, eight hydrogen (H) atoms, and one oxygen (O) atom. As a secondary alcohol, it is a chemical compound that is connected to the first carbon atom through the help of hydroxyl (OH) group. These significantly contribute to its high solvent properties by breaking down oils, grease, and other nonpolar substances very well. 

• • Rate of evaporation and Residue-Free Drying: 

Isopropyl alcohol’s quick evaporation rate is the primary feature that gives it the advantage over other solvents. Isopropyl alcohol, because of its low boiling point (82.6°C or 180.7°F), will evaporate within seconds after applying it to any surface such as electronic equipment, glass, or an optical instrument. It should be emphasized that this cleaner does not leave any residues like those of water-based cleaners, thus making sure that the surface will be clean and with no dirt. 

This is further of much convenience when it comes to the cleaning of circuit boards, optical lenses, and delicate mechanical system

• • Purity and Concentrations: 

Isopropyl alcohol is the one that comes in different purity levels. Such purity levels are commonly known as 70%, 91%, and 99%. The best concentration can be different, but it is typically in relation to the purpose. 

• • 70% Isopropyl Alcohol: Mostly, people take it in the form of spraying or rubbing to the skin to kill microorganisms. Besides, the presence of water within makes the drug work by drying off and then the bacteria and virus are gone, thus sanitizing the household and medical institutions. 

• • 91% Isopropyl Alcohol: This version of the drug is more concentrated and dries up faster; the part that evaporates quickly makes it a fit for electronics cleaning, removing sticky residues, and industrial tasks. At the same time, it is helpful for dissolving non-polar materials. 

• • 99% Isopropyl Alcohol: This one is the ultrapure form that is made by many companies and is used almost exclusively in their laboratories, industries, and computers. Even though it is very effective in disinfecting, it will not work as an antiseptic as it evaporates in an instant and it might cause skin irritation due to its harshness. Moreover, it could bring about excessive dryness.
    
    

• • Flammability and Storage Precautions: 

Isopropyl alcohol is extremely flammable, and its flash point is in the range of 52-55°F (11-13°C). The vapors can easily catch fire, so it is highly important to handle and store isopropyl alcohol with caution. The safety is to be guaranteed to: 

• • Keep it away from open flames, sparks, and sources of heat. Isopropyl alcohol is always to be stored in cool, well-ventilated places and if it is possible in containers that have lids to avoid their evaporation and the buildup of vapors. 

• • The standard precautions of proper labeling and handling should be maintained, especially in the industrial and laboratory environments to avoid fire hazards.
    
    

When users are knowledgeable about these features, they can responsibly and efficiently employ isopropyl alcohol for a wide variety of applications starting with its use as a disinfectant to the most demanding work such as industrial cleaning.

Common Uses of Isopropyl Alcohol

• • Cleaning Electronics 

One of the prevalent uses of isopropyl alcohol is for cleaning circuit boards, screens, keyboards, connectors, and other delicate electronic components. Isopropyl alcohol is a popular choice for the cleaning of sensitive equipment because of its rapid evaporation and its ability to dry residue-free. It is very safe to operate with, since it does not result in any short-circuiting or damage to the moisture left behind by equipment. 

Technicians frequently apply 99% isopropyl alcohol to clean PCBs (printed circuit boards), get thermal paste off of CPUs, and degrease sensitive parts in electronic devices. It is likewise efficient in the case of cleaning smartphone screens, camera lenses, and optical sensors without leaving streaks or damage. 

• • Disinfecting Surfaces 

As a strong antiseptic, isopropyl alcohol is usually used for disinfecting countertops, doorknobs, medical instruments, and other high contact surfaces. It is specifically very effective against a range of bacteria, viruses, and fungi; therefore, it becomes an indispensable disinfectant in hospitals, clinics, laboratories, and households. 

Medical technical staff often use 70% isopropyl alcohol because of its perfect balance of water content allowing it to better penetrate the microbial cell wall than higher concentrations. It is also used in hand sanitizers and antiseptic wipes.

• • First Aid Antiseptic 

Isopropyl alcohol is a very common method when it comes to little cuts, scrapes, and burns as an antiseptic to keep the infection away. The main principle is to make them die by killing bacteria off the surface while also keeping the possibility that the skin will get further infected by lowering. In point of fact, if the application is done directly to the wounds, the areas may have irritation or a burning sensation, on the other hand, long-term use may produce skin dryness. 

As for medical facilities, swabs made of alcohol that hold isopropyl alcohol are utilized to decontaminate the skin before at the time of injecting or taking blood samples to make sure that all the hazards are driven away.

• • General Cleaning 

Due to its solvent properties, isopropyl alcohol is an excellent degreaser and stain remover. It’s commonly used for the following purposes: 

• • To remove gluey leftovers from stickers, tapes, and adhesives. 

• • To clean glass to a point where they look like they were never there, and to leave a flawless surface of mirrors and windows. 

• • The removal of ink stains and permanent marker marks from surfaces. 

• • Sanitization of personal accessories such as razors, combs, brushes, and jewelry. 

• • Deodorizing and disinfecting gym equipment and yoga mats by means of the breakdown of sweat and bacteria.

What is Rubbing Alcohol?

Rubbing alcohol is a term for solutions that have for their basis or mixed with water and additives either isopropyl alcohol or ethanol. This liquid has a wide range of applications in the household thanks to its antiseptic and cleaning properties. Alcohol for rubbing may contain different ingredients as compared to pure isopropyl in order to make it usable or safe.

Properties of Rubbing Alcohol

• • Main Ingredient 

The general concept of alcohol-based antiseptic solution is the term rubbing alcohol and it can be either isopropanol or ethanol as an active ingredient. The brand and the intended use are the variables that must be taken into account in the formulation procedure. However, the main common active agents in this kind of product are isopropyl alcohol and ethanol. 

• • Isopropyl Alcohol-Based Rubbing Alcohol: It is the most popular in the United States which can be found at concentrations of 50-70%. As one of its main properties, after applying it, it leaves a clean and bright surface, and is widely recognized as the energy-efficient material. It is usually found used as a solvent, but it is also used in the manufacturing of paints.
    
    

• • Alcohol Concentration 

Different concentrations of rubbing alcohol are available, which are typically 50% to 70% of alcohol content. The content of alcohol is the determining factor of it’s efficiency and the specific usage: 

• • 50-60% Alcohol: Use for skin antiseptics and personal care products is very common, as the lower concentration helps avoid skin irritation. 

• • 70% Alcohol: Incidentally, the most successful concentration of killing bacteria and viruses is 70% alcohol. The remaining water as an impediment accelerates the evaporation process of the alcohol carried out, thus not achieving the microbe target. It’s the best concentration for medical houseplants, hospital use, and household disinfection.
    
    

• • Additives in Rubbing Alcohol 

Grades of rubbing alcohol are not as pure as those of isopropyl or ethanol; they usually contain other substances that can give them specific properties or that can discourage their misuse. Among the most used additives are: 

• • Fragrances: Some of the compositions contain aroma substances such as menthol, wintergreen or lavender which give a more pleasant experience to the user. 

• • Denaturants: These substances are added to ethanol-based rubbing alcohol to make the alcohol unsuitable for drinking thereby reducing the chances of accidental consumption. 

• • Emollients: Dryness is fought off with the help of alcohol, which is done by the moisturizers like glycerin or aloe vera that are included in some rubbing alcohols to make them gentler to the skin.
