IPA 99% Compared To IPA 70%


The Differences Between IPA 99% and IPA 70%

IPA 99% or Isopropyl alcohol 99% is used in many applications as a powerful cleaning agent and method of preservation.

IPA 70% is not the same as IPA 99%. IPA 70% is found in common household products such as rubbing alcohol.

IPA General Information

  • Rubbing alcohol is a mixture of compounds, while isopropyl alcohol 99% is pure alcohol.
  • IPA 99% is more closely related to propanol, while rubbing alcohol derives from ethyl alcohol.
  • IPA 99% is not safe to ingest in any form and less common for consumer use, while IPA 70% as a product of ethyl alcohol can be found in common alcoholic beverages such as beer, wine, brandy, and whiskey.
  • Rubbing alcohol is a variant of denatured alcohol.
  • Rubbing alcohol has 70-95% ethanol, and can also be found as Isopropyl Rubbing Alcohol which contains around 95% ethanol.
  • IPA 70% is also less toxic and flammable than IPA 99% and evaporates more slowly.


IPA 70% can be more versatile than IPA 99%, because IPA 70% can be safely used for both industrial and household applications.

Both IPA 70% and IPA 99% are useful antiseptics and play an important role in at home and professional medical care.

This is one of the many reasons that while IPA 70% may be cheaper and more versatile than IPA 99% in some circumstances.

Why Choose IPA 99%?

Sensitive electronic devices, such as computer chips, and circuit boards, are best manufactured with IPA 99% because of its fast drying and low water content qualities.

IPA 99% is also a much more effective cleaning agent than IPA 70%, because of its extremely fast evaporation and the fact that it is pure, completely non denatured alcohol.

Though IPA 99% is flammable, it is the strongest alcohol cleaning agent available to ensure optimal medical and industrial cleaning.

IPA 99% can also utilized to remove most inks, pastes, oils, and other contaminants associated with machinery and printing.

High purity alcohol is much better for cleaning electronics, because that is what is used in the manufacturing of the product.

The important difference between IPA 70% and IPA 99% to remember is that the additional 30% of substance that comprises IPA 70 is not always water, there may be additives included that would not be safe for all cleaning applications.

This uncertainty is where the purity of IPA 99 truly comes in handy.

IPA 99’s extremely fast evaporation leaves no residue behind after any sort of application.

This is one of the many reasons why IPA 99 is a better cleaning agent than IPA 70.

Simply put, Isopropyl Alcohol 99% is a safe, pure, strong, and effective solvent and cleaning agent that is useful in the medical, household, laboratory, and manufacturing industries.

Isopropyl Alcohol: What is An IPA Cleaner?

Isopropyl alcohol (IPA) is a compound with the chemical formula C3H8O or C3H7OH or CH3CHOHCH3. Chemical elements that form the compound make it colorless — a desirable quality for cleaning minutely porous materials that could absorb color from cleaners — and highly evaporable, which makes it an optimal solution for cleaning soils from electronics.

Consequently, care must taken when using an IPA in an environment that has ignition sources. Fire hazard must also be considered when storing the popular cleaner. And workers who use IPA regularly can benefit from wearing respirators — and potentially other protective gear, depending on whether IPA is combined with other elements to create an IPA cleaner.

Classes of IPA

There are several classes of IPA based on intended use: industrial, cosmetic, pharmaceutical (USP), reagent, and electronic. At Ecolink, we specialize in IPA for general industrial use and cleaning electronics. Industrial grade IPA is primarily used as a solvent and cleaner. Electronic IPA is used in the same capacity, cleaning printed circuit boards (PCB) and flat panel displays (FPD), along with a many other electrical parts and apparatuses.

IPA Vs. IPA Cleaner

IPA from IPA cleaner is splitting hairs. IPA itself is a formidable cleaner; albeit, one with various purity levels that impact how and where it is used. The term ”IPA cleaner” commonly refers to cleaners containing the compound along with other active ingredients.

An IPA cleaner — as distinguished from pure IPA — commonly refers to cleaners using IPA to create industrial cleaner, such as IPA-based acetone, 2-bromopropane, and propene. However, because IPA with high a purity level is an excellent cleaner, organizations often use IPA alone, both as a general cleaner and a solvent for cleaning electronic components.

IPA Purity Levels

The efficacy and range of application for IPA depends on its purity. For example, pharmacy-grade rubbing alcohol, hand sanitizers, and disinfecting wipes commonly use a 60%–70% IPA solution in water. But industrial grade IPA frequently contains over 99% pure IPA.

The high purity enhances the compound’s natural qualities. Beneficial for cleaning electronics, evaporation rate increases. Another benefit is that high-purity IPA cleaner is affordable and more efficacious compared to other solutions (e.g., ethanol, n-butanol, and methanol). for some of the same applications.

IPA’s primary downsides are high flammability and high evaporation rate. As mentioned previously, the high evaporation is excellent for cleaning electronics; however, depending on the amount used, a special air filtration system and personal protective equipment (PPE) may be needed in the application environment.

IPA Solvent Uses: 4 Examples of Industrial Use

Isopropyl alcohol (IPA) has a wide variety of uses, from serving as a disinfectant for minor wounds to cleaning a variety of objects and surfaces in industrial settings. In this entry, we focus on the latter area of use, providing three examples of IPA solvent uses in industrial settings. The class of IPA we’re discussing is industrial grade IPA, whose purity exceeds 99%. This level of IPA density is generally unnecessary for commercial and residential IPA applications.

  1. Cleaning General Surfaces

IPA solvent uses include cleaning general surfaces. Types of metal and coated surfaces routinely found in industrial settings are generally unreactive to IPA. However, the cleaner is known to tarnish varnishes and ruin the erasability of dry erase boards.

Varnish and material coating dry erase boards aren’t common in industrial work areas, but IPA’s deleterious effect on these surfaces — an effect that depends partly on the purity of IPA — serve as notice that the compatibility of a material with IPA should be check before the cleaning operation commences.

  1. Cleaning Electronic Components

IPA solvent uses also involve cleaning electronic parts. The list is long, with some of the more popular IPA-cleaned electronic parts and apparatuses being contact pins in ROM cartridges,

magnetic tape, disk heads for legacy floppy disk drives, computer screens, optical disc drive lasers for CDs and DVDs, and IC packages.

What method of IPA deployment should be used to clean these and other components? The answer largely depends on the geometry of a component and where it’s situated in proximity to surrounding components. Due to aerosol particles’ ability to distribute evenly across intricate spatial configurations, IPA in aerosol form is optimal for parts that have complex geometries or are surrounded by parts that make them difficult to access.

  1. Minimizing Solvent Waste

From an industrial user’s standpoint, a potential drawback of IPA solvent uses is the fire hazard they entail. High-purity IPA has an an open cup flashpoint of 11.7°C (53.1°F; 284.8 K) and a closed cup flashpoint of 13°C (55°F).

IPA solutions can be diluted with water and made less flammable. But when it comes to solvent disposal, this isn’t quite the point. Rather, the high evaporation rate of IPA helps it evaporate before it enters the waste trap, especially when high-purity IPA is deployed as aerosol, or in the form of wipes. A potential benefit of IPA solvent use is reduced chemical waste disposal cost.

IPA Cleaning Liquid Vs. Other Alcohol Cleaners

For industrial cleaning, isopropyl alcohol (IPA) is prefered over other types of alcohol for several reasons. In addition to IPA cleaning liquid, cleaning liquids containing methyl alcohol, ethyl alcohol, and butyl alcohol are commonly used for various cleaning operations, from removing grime from work surfaces to cleaning away dirt from electronic components.

So, exactly why should you choose an IPA cleaning liquid over a cleaning liquid that contains a different type of alcohol? Once you see the drawbacks to using methyl, ethyl, and butyl alcohols, the answer is clear. You’ll want to use an IPA-based cleaner instead of cleaner that uses a different alcohol base.

Methyl Alcohol

IPA has a high vapor density that produces a high evaporation rate, but the vapor density of methyl alcohol is three times higher than IPA’s. In addition to profusely filling the work environment with head spinning alcohol fumes, the high evaporation rate of methyl alcohol makes it difficult to use efficiently, especially in the form of saturated wipes. Methyl alcohol wipes dry quickly, making them best for cleaning soils from a small surface area.

Ethyl Alcohol

Ethyl alcohol (a.k.a. ethanol) is found in most alcoholic beverages. For example, a beer that has 7.5% alcohol contains 7.5% ethyl alcohol per volume. Pure ethyl alcohol used for cleaning would taste wretched to drink, as it’s nearly 100% pure. But people have been known to consume it. This is why the U.S. Government regulates the substance, regardless of intended use.

According to an article from Berkshire, “In order to use pure ethyl alcohol (un-denatured) for wiping purposes would require applying for government permits and complying with usage tracking procedures — more trouble than it’s worth.”

Butyl Alcohol

Butyl alcohol has a lower vapor density than isopropyl, methyl, or ethyl alcohol, having about ? of the vapor pressure of IPA. On the downside, in addition to having an exceptionally pungent smell, butyl alcohol has a high hydrocarbon content that limits its solubility. A mixture of 90% water and 10% butyl is about the best you can do. In comparison, IPA cleaning liquid can contain any alcohol to water ratio.

As Berkshire notes, “The banana-like odor of butyl alcohol would render it objectionable to most cleanroom operators for long-term use. More importantly, the higher hydrocarbon content of butyl alcohol limits its solubility in water to about a 10 percent solution. By comparison, IPA is miscible in water at all concentrations.”
