What You'll Learn

Mineral spirits are distilled from petroleum oils, unlike turpentine
Mineral spirits, also known as white spirits, are distilled from petroleum oils and are used as paint thinners and mild solvents. They are heavily refined during production to reduce toxic volatile organic compounds (VOCs) and sulfur. Mineral spirits are also used to thin oil-based paints and to clean brushes and rollers. They are less toxic than other paint thinners and have a smoother finish.
Turpentine, on the other hand, is distilled from the resin of trees, mainly pine. It is a natural product derived from the distilled resinous sap found in pine trees. Turpentine has been traditionally used as a paint thinner and solvent, but it has a strong odour and is more expensive than mineral spirits.
The key difference between mineral spirits and turpentine lies in their distillation processes and sources. Mineral spirits are distilled from petroleum, while turpentine is derived from natural sources such as pine trees. The distillation process for mineral spirits aims to reduce toxic compounds and odour, resulting in a product that is less toxic and less irritating than turpentine.
Mineral spirits are also preferred for indoor work due to their lower odour and less concentrated fumes. They are widely used in the paint industry and are known for their ability to thin oil-based paints effectively. Additionally, mineral spirits are less expensive than turpentine, making them a cost-effective choice for painters and DIY enthusiasts.
While mineral spirits offer advantages over turpentine, it is important to note that both are solvents and should be handled with care. Adequate ventilation, limited exposure, and following manufacturer recommendations are crucial when working with these products.

Mineral spirits are less toxic than turpentine
Mineral spirits and turpentine are both solvents and are used to thin oil-based paints. However, mineral spirits are less toxic than turpentine. Mineral spirits are heavily refined during production to reduce toxic volatile organic compounds (VOCs) and sulfur. Odorless mineral spirits are also available, in which these toxic compounds have been completely eliminated. Mineral spirits are therefore preferred for indoor work, where solvent fumes and odours are concentrated.
Turpentine, on the other hand, is distilled from the resin of pine trees and has a foul odour and caustic nature. It is also more expensive than mineral spirits. Due to these factors, mineral spirits were developed as a safer, gentler solvent.
In terms of functionality, mineral spirits are only capable of removing wet paint, whereas turpentine can remove dried paint. Paint thinned with mineral spirits also dries to a smoother, more even finish.
It is important to be careful with any solvent, regardless of safety. Adequate ventilation, avoidance of excessive skin contact, and use of any recommended respirators are always advised.

Mineral spirits are more expensive than turpentine
Turpentine, on the other hand, is distilled from the resin of trees, mainly pine. It has a strong odour and is more caustic than mineral spirits. It also has stronger solvency than mineral spirits, meaning it can remove dried paint. Despite these differences, both mineral spirits and turpentine are solvents used to thin oil-based paints and clean brushes and rollers.
The cost of mineral spirits can vary depending on the retailer and the specific product, but on average, they are more expensive than turpentine. For example, a gallon of mineral spirits can range from $10 to $15, while a gallon of turpentine may cost around $8. The higher cost of mineral spirits is due to the additional refining process required to reduce toxic volatile organic compounds (VOCs) and sulfur. This results in a less toxic and less odorous product, making it preferable for indoor work where fumes can be concentrated.
While mineral spirits are more expensive, they offer advantages that may justify the higher cost for certain applications. Their slower evaporation rate and less toxic nature make them a popular choice for those concerned about introducing harmful pollutants into their homes. Additionally, their mild odour and non-sticky residue contribute to their popularity.
In summary, mineral spirits are more expensive than turpentine due to the additional refining process they undergo. This process reduces toxic compounds, improves handling, and results in a less odorous product. While turpentine may be more cost-effective, mineral spirits offer advantages in terms of toxicity, ease of use, and finish quality that make them a preferred choice in certain situations.

Turpentine is distilled from the resin of pine trees
Mineral spirits, paint thinner, and turpentine are solvents used for thinning oil-based paint, stains, and varnishes, as well as for cleaning paint equipment and oily materials. While mineral spirits and paint thinner are often used interchangeably, turpentine is a product derived from living pine trees or citrus rinds.
Turpentine production may involve the use of specific pine species, such as longleaf pine, slash pine, maritime pine, Aleppo pine, Masson's pine, Sumatran pine, loblolly pine, ponderosa pine, and Scotch pine. The choice of pine species depends on the region and availability. In addition to distillation from pine resin, turpentine can also be extracted through the destructive distillation of pine wood, such as shredded pine stumps, roots, and slash. This process utilizes the light end of the heavy naphtha fraction, which boils between 90-115°C (195-240°F).
Turpentine has been used historically for various purposes, including as a solvent, paint thinner, furniture wax (when mixed with beeswax), lubricant, disinfectant, and fuel for lamps. It is also added to cleaning and sanitary products due to its antiseptic properties and pleasant scent.

Turpentine has a strong odour and is caustic
Turpentine is derived from the resinous sap of pine trees, specifically the distillation of resin harvested from living trees, mainly pines. The word turpentine is derived from the Greek word "τερεβινθίνη", which means resin. The average yield of crude sulfate turpentine is 5-10 kg/t pulp. It is used as a solvent for thinning oil-based paints and varnishes, and as a raw material for the chemical industry.
Turpentine has a strong odour, which has been described as "foul" and "like death". This is due to the distillation process, which involves boiling pine wood, stumps, roots, and slash at extremely high temperatures. The high temperatures can cause the organic compounds in the pine to break down and release volatile compounds, which can have a strong odour.
Turpentine is also caustic, which means it can be corrosive and damaging to the skin, eyes, and other tissues. It can cause skin and lung irritation, nervous system damage, and even kidney disease. It is important to take safety precautions when using turpentine, such as wearing protective clothing, gloves, and eye protection, and ensuring adequate ventilation.
Due to its caustic nature and strong odour, turpentine has been largely replaced by turpentine substitutes obtained from petroleum, such as mineral spirits (also called white spirits), which are safer and gentler solvents. Mineral spirits are derived from petroleum oils and have several advantages over turpentine, including a lower price, no sticky residue, and less likelihood of affecting those with allergies.
