Methylated Spirit vs. Turpentine

What's the Difference?

Methylated spirit and turpentine are both commonly used as solvents in various applications, but they have distinct differences. Methylated spirit, also known as denatured alcohol, is a type of alcohol that has been rendered undrinkable by the addition of toxic substances. It is often used as a cleaning agent or fuel for camping stoves. Turpentine, on the other hand, is a natural resin-based solvent derived from pine trees. It is commonly used in painting and varnishing as well as for cleaning brushes and removing paint. While both substances are effective solvents, turpentine has a stronger odor and can be more irritating to the skin and respiratory system compared to methylated spirit.

Further Detail

Introduction

When it comes to solvents and cleaning agents, methylated spirit and turpentine are two commonly used options. Both substances have their own unique attributes and are used for different purposes. In this article, we will compare the characteristics of methylated spirit and turpentine to help you understand the differences between the two.

Chemical Composition

Methylated spirit, also known as denatured alcohol, is a mixture of ethanol and other chemicals such as methanol or isopropanol. It is commonly used as a solvent, fuel, or cleaning agent. On the other hand, turpentine is a liquid distilled from pine resin. It is composed of various hydrocarbons, primarily pinene. Turpentine is often used as a solvent in painting and varnishing.

Odor

One of the most noticeable differences between methylated spirit and turpentine is their odor. Methylated spirit has a strong, pungent smell that is often described as sharp or medicinal. This odor can be overpowering and unpleasant to some individuals. Turpentine, on the other hand, has a distinct pine scent that is more natural and earthy. Some people find the smell of turpentine to be more tolerable than that of methylated spirit.

Flammability

Both methylated spirit and turpentine are highly flammable substances. Methylated spirit has a flash point of around 11°C, making it extremely volatile and prone to catching fire. Turpentine, on the other hand, has a flash point of around 35°C, which is slightly higher than that of methylated spirit. It is important to handle both substances with caution and keep them away from sources of ignition.

Uses

Methylated spirit is commonly used as a solvent for cleaning surfaces, removing stains, and disinfecting wounds. It is also used as a fuel for camping stoves and alcohol burners. Turpentine, on the other hand, is primarily used in painting and varnishing as a solvent for oil-based paints and finishes. It can also be used as a cleaner for brushes and other painting tools.

Toxicity

Both methylated spirit and turpentine can be toxic if ingested or inhaled in large quantities. Methylated spirit contains denaturants such as methanol, which can be harmful if consumed. Inhaling the fumes of methylated spirit can also cause respiratory irritation. Turpentine, on the other hand, can cause skin irritation and respiratory issues if not used properly. It is important to use both substances in a well-ventilated area and avoid direct contact with the skin.

Cost

In terms of cost, methylated spirit is generally more affordable than turpentine. Methylated spirit is widely available and can be purchased at most hardware stores or pharmacies at a relatively low price. Turpentine, on the other hand, is more expensive due to the extraction process and limited availability. Artists and painters may need to budget for the higher cost of turpentine compared to methylated spirit.

Conclusion

In conclusion, both methylated spirit and turpentine have their own unique attributes and are used for different purposes. Methylated spirit is a versatile solvent and cleaning agent with a strong odor and high flammability. Turpentine, on the other hand, is a natural solvent with a pine scent that is commonly used in painting and varnishing. It is important to consider the specific needs of your project when choosing between methylated spirit and turpentine.
