Does Kutzit Cause Leukemia?

Published on July 29th, 2022 by Andrew Hughes

Individuals who have had long-term exposure to Kutzit may be at an elevated risk for leukemia. Why is that? Because, historically, Kutzit contained high levels of benzene.

What is Kutzit?

Kutzit is a popular paint, varnish, and lacquer stripper that has been around for decades. It is used by painters and other tradesmen as well as household consumers. Kutzit is made up of a mixture of powerful solvents. Like many other popular stripper products, Kutzit uses solvents that are derived from petroleum (i.e. petroleum solvents). Benzene is a petroleum solvent, and for many years it was the primary ingredient in Kutzit.

Eventually, the benzene in Kutzit was replaced with other petroleum solvents. However, due to cost considerations in the distillation process, just about every industrial petroleum solvent is contaminated with some level of benzene. Consequently, even in recent years, Kutzit may have contained dangerous levels of benzene.

What is Benzene?

Benzene is a carcinogenic aromatic hydrocarbon. Benzene is colorless at room temperature, it has a sweet smell, and it is highly flammable. The International Agency for Research on Cancer (IARC) classifies benzene as a group one carcinogen.[1] Examples of other group one carcinogens include asbestos, plutonium, and tobacco.

Which Cancers are Linked to Benzene?

Benzene exposure can lead to numerous diseases including:

How Much Exposure to Benzene is Dangerous?

The only safe level of benzene exposure is zero. This fact was even recognized by the American Petroleum Institute (API) as early as 1948.[2]

How Much Benzene is in Kutzit?

Kutzit was originally formulated to contain more than 50% benzene (AKA “benzol” at the time) and was marketed as “Paint Remover Liquid-Benzol.” Kutzit’s manufacturer claimed to have removed benzene entirely from the product sometime in the early 70s. However, in a study conducted on the product in 1978, gas chromatography analysis revealed that Kutzit was 52% benzene by volume.[3]

Today, pure benzene is no longer used as an active ingredient in Kutzit. Kutzit now relies on other petroleum solvents such as toluene. However, even today, Kutzit still contains benzene.

Toluene is a close relative of benzene. The refining process that yields toluene from petroleum simultaneously produces benzene.[4] Separating the toluene from the benzene entirely is much more costly for the manufacturer. As a result, industrial grade toluene can retain significant amounts of benzene. Purified toluene (what would be used in laboratories) might only contain as little as 0.01% benzene. However, crude toluene might contain as much as 25% benzene.[5-8]

Current regulations require that Kutzit’s manufacturer report how much toluene is used in its product. The most current MSDS for Kutzit available on the manufacturer’s website indicates that Kutzit is 25-30% toluene. However, the manufacturer is not required to report how much benzene is present in the toluene they use. Consequently, there is no way for a normal consumer to know how much benzene is in the product they are using.
