Mineral spirits and terpene-based substitutes like Turpenoid are both solvents used to thin oil-based paints and clean brushes. Mineral spirits are derived from petroleum distillates and are heavily refined to reduce toxic volatile compounds and sulfur, resulting in a milder odour and lower toxicity compared to paint thinners like turpentine. While mineral spirits are generally considered safer and more user-friendly, some individuals may develop sensitivities or allergies to them, manifesting as skin rashes or respiratory issues. In such cases, terpene-based alternatives with lower toxicity, such as Turpenoid, can be preferable. However, it's important to note that these alternatives may not work as effectively with certain paints, as evidenced by the experience of a user who tried using a generic low-odour mineral spirit with Pebeo Fantasy Paints, resulting in a thick, unusable paint consistency. Thus, when considering substitutes for mineral spirits, it is essential to carefully evaluate their compatibility with specific paints and always take the necessary precautions, such as wearing protective gear and ensuring adequate ventilation.

What You'll Learn
Turpentine is more toxic than mineral spirits
Mineral spirits, also known as mineral turpentine, are commonly used as a substitute for turpentine. They are less flammable and less toxic than turpentine, making them a safer option for artists and painters. The process of refining mineral spirits removes the more toxic aromatic compounds, resulting in a less toxic product. This makes mineral spirits ideal for applications such as oil painting, where close contact with the solvent is necessary.
Turpentine, despite being more toxic, has its own advantages. It has been used for centuries with natural varnish resin, oil pigments, and raw linseed oil. In antique restoration and museum conservation, pure gum turpentine is highly valued for its ability to dissolve wax finishes, varnishes, and Danish oil finishes. It also serves as an excellent solvent for emulsified bee's wax and raw linseed oil finishes.
However, due to its toxicity, turpentine should be avoided unless specifically required, such as when dissolving a varnish resin or using a medium that contains a resin dissolved in gum turpentine. Mineral spirits, on the other hand, can be used effectively as a thinner for oil paints in the early stages of painting. While mineral spirits are generally safer, it is important to avoid overusing them as a thinner to prevent the paint from becoming underbound and unable to adhere properly.
In summary, when considering the toxicity of turpentine and mineral spirits, mineral spirits emerge as a safer and more refined option for artists and painters. Turpentine, while offering certain advantages in specific scenarios, is more toxic and should be used with caution, especially when alternative options like mineral spirits are available.

Paint thinner is a type of mineral spirit
Paint thinner and mineral spirits are indispensable solvents for thinning oil-based paint, stains, and varnishes, as well as for cleaning paint equipment and oily materials. Paint thinner is a more generic term that defines the purpose of the product. Paint thinner is a common phrase for solvents used when thinning paint. Examples of paint thinners include acetone, turpentine, toluene, and mineral spirits. The word "paint thinner" describes the solvents used to thin paint, not necessarily the makeup of the product.
Mineral spirits, on the other hand, is a term that specifies the product's composition. Mineral spirits are derived from minerals, specifically 100% petroleum distillates, and have no additives. They are heavily refined to remove toxic compounds such as VOCs and sulfur, resulting in a less toxic product that is easier to work with. Mineral spirits are also more expensive than paint thinners, with a gallon of mineral spirits costing around $10 and odor-free mineral spirits costing $15, compared to $8 per gallon for paint thinners.
Both paint thinner and mineral spirits can be used interchangeably for thinning paint and as paint removers. However, mineral spirits are preferred by many professional painters and artists due to their lower toxicity, slower evaporation rate, and smoother finish. The slower evaporation rate of mineral spirits also makes them suitable for cleaning surfaces.
In summary, paint thinner is a type of mineral spirit in its simplest form without any additives. While they have similar compositions and functions, mineral spirits are generally preferred due to their lower toxicity, slower evaporation rate, and smoother finish when thinning paint.

Mineral spirits are more expensive than paint thinner
Mineral spirits and paint thinners are often confused with each other. They are both derived from minerals and are interchangeable in many aspects. They are used to thin paint and work as paint removers. However, they have different chemical compositions and are two different products.
Mineral spirits are heavily refined to remove toxic compounds such as benzene and toluene, as well as sulfur. This makes it less toxic and easier to deal with than paint thinner. It also has a very low odor compared to paint thinner. Due to its refinement process, mineral spirits are more expensive than paint thinner. For example, a gallon of mineral spirits costs $10 on average, while odor-free mineral spirits cost around $15 per gallon. In comparison, paint thinners cost only $8 per gallon. The extra energy required to purify and refine mineral spirits accounts for its higher average cost.
The lower toxicity and odor of mineral spirits make it preferable for indoor use and for those who are sensitive to fumes. It is also better for thinning oil-based paints due to its slow evaporator factor, resulting in a smoother finish. Several professional painters and artists also prefer mineral spirits for cleaning their painting utensils.
While mineral spirits are more expensive than paint thinners, the cost difference is relatively minimal, and the higher cost may be worth it for the benefits of lower toxicity and odor.

Mineral spirits are better for thinning paint
Mineral spirits and paint thinners are the principal solvents used to thin oil paint. Although both are made of petroleum goods, they have different chemical compositions. Mineral spirits are a heavily refined distillation of petroleum, which reduces toxic volatile organic compounds (VOCs) and sulfur. This makes mineral spirits less toxic and easier to handle than paint thinners. Paint thinners contain toxic compounds such as benzene and toluene, which make them unsafe around children and pets.
Mineral spirits are also less smelly than paint thinners, and an odourless version is available. Paint thinners, on the other hand, have strong fumes and should be used in well-ventilated areas. Paints thinned with mineral spirits also dry to a smoother, more even finish than those thinned with paint thinners. This is because paint thinners evaporate faster.
The combination of stand oil and mineral spirits is one of the best mediums to use with oil paints. Mineral spirits can also be used by themselves to thin oil paint in the early stages of painting. However, it is important not to overuse mineral spirits as a thinner, as this can result in underbound paint that won't stick to the ground.
Although mineral spirits are more costly than most types of paint thinner, they are more versatile and less toxic. If you have allergies or respiratory issues, mineral spirits are a safer option than paint thinners.

Turpentine is better for dissolving varnish
Turpentine is a natural resin extracted from trees, specifically the sap of pine trees. It is a traditional solvent that has been used for millennia, especially with natural varnish resin, oil pigments, and raw linseed oil. Linseed oil varnish is highly soluble in turpentine at room temperature, and the two substances cannot be separated by distillation once combined. Turpentine also acts as a drier in linseed oil varnish, absorbing oxygen from the air faster and more efficiently than linseed oil.
Mineral spirits, on the other hand, are made from petroleum distillates. They are heavily refined to remove toxic compounds, which makes them less toxic than turpentine. They are also slower to evaporate, which makes them more effective at thinning oil-based paints. However, overuse of mineral spirits can result in underbound paint that won't stick to surfaces.
While mineral spirits are a good solvent for thinning oil paints, especially in the early stages of painting, turpentine is superior when it comes to dissolving varnish. This is because turpentine has a long history of use with natural varnish resin and is uniquely suited as a solvent for linseed oil varnish.
In addition, turpentine is a versatile product with a wide range of applications. It is an essential component in the making of varnish, and it is also used in medicine and as a conservator for fine art and antiquities. The pure gum spirits variety of turpentine is particularly effective as a solvent for wax finishes, varnishes, and Danish oil finishes.
In conclusion, while mineral spirits have their advantages in terms of lower toxicity and slower evaporation, turpentine is the better choice for dissolving varnish due to its unique solubility with linseed oil and its long history of effective use in this application.
