Also known as "mineral spirits," "Stoddard solvent," and "white spirits."
Very close to turpentine and paint thinner, which you can buy at the
hardware store.
NO! Turpentine is VERY different indeed chemically. 'Paint thinner'
these days can be anything from water, through ethylene trichloride and
carbon tetrachloride to 'white spirit' and stuff more like gasoline.

Note the description is almost word-for-word the same as 60950-1!
Suspiciously like it. In fact, the description is internally
inconsistent and not reliable. It says first:
It is a mixture of aliphatic and alicyclic C7 to C12 hydrocarbons with a
maximum content of 25% of C7 to C12 aromatic hydrocarbons.
NOTE THAT: 25%
C7 to C12 means heptane to dodecane, not hexane at all, and the 25%
aromatics makes it a far more aggressive solvent for some materials than
hexane is.
The following text is garbled and repetitive and it's only there that
the 'magic words' hexane, kauri-butanol etc. appear:
A typical composition for mineral spirits is the following: > 65% C10 or
higher hydrocarbons, aliphatic solvent hexane,
and a maximum aromatic hydrocarbon content of 0.1% by volume,
NOTE THAT: 0.1% It lost 24.99% in two lines of text!
a kauri-butanol value of 29, an initial boiling point of 149 °F (65 °C),
a dry point of approximately 156 °F (69 °C), and a specific mass of 0.7
g/cc. Stoddard solvent is a specific mixture of hydrocarbons typically >
65% C10 or higher hydrocarbons.
