Copper naphthenate sold for pressure treatment of wood is typically supplied as an 8% copper (as metal) concentrate for dilution to 0.5-1.5% copper (as metal) treating solutions. Copper naphthenate sold at retail for consumer use is typically a 1% or 2% copper ready-to-use solution in mineral spirits or other similar solvents.
It has a flash point of more than 60 °C, and works as a forming fluid in metalworking, as a household cleaner, a household polisher, and a liquid vaporizer. As of 2019 it is not available to the general public in its pure form, but may be found in the ingredients lists of some cleaning agents and solvents. [3] By weight, it consists of: [1]
A 2-litre (3.5 imp pt) container of white spirit. White spirit (AU, UK and Ireland) [note 1] or mineral spirits (US, Canada), also known as mineral turpentine (AU/NZ/ZA), turpentine substitute, and petroleum spirits, is a petroleum-derived clear liquid used as a common organic solvent in painting.

According to Paracelsus (1493–1541), the three primes or tria prima – of which material substances are immediately composed – are: [2] Sulfur or soul, the principle of combustibility: 🜍 Mercury or spirit, the principle of fusibility and volatility: ☿ Salt or body, the principle of non-combustibility and non-volatility: 🜔 ()
These solvents are volatile organic compounds (VOCs), with white or mineral spirits having a very low flash point at about 40°C (104°F), the same as some popular brands of charcoal starter. All such solvents with low flash points are hazardous and must be labelled as flammable .
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
The technical definitions vary between countries so the United Nations created the Globally Harmonized System of Classification and Labeling of Chemicals, which defines the flash point temperature of flammable liquids as between 0 and 140 °F (60 °C) and combustible liquids between 140 °F (60 °C) and 200 °F (93 °C).
Mineral Spirits, often referred to as paint thinner, represent a complex petroleum distillate with a flash point range between 104 degrees F (40 degrees C) and 110 degrees F (43 degrees C). With an ignition temperature of 473 degrees F (245 degrees C) and explosive limits of 0.8% at 212 degrees F (100 degrees C), mineral spirits possess a vapor ...
