Detailed Product Description:
A colorless, low odor organic liquid. Soluble in water, methanol and
ether. Also known as mineral spirits or white spirits outside of the United
States, Stoddard solvent is a paraffin-derived clear liquid commonly used
in painting and decorating.
Grade/Purity:
Because of interactions with pigments, artists require a higher grade of
mineral spirits than the typical industrial users, including the complete
absence of residual sulfur. This particular grade is known as Type 3
(for minimum sulfur content), Low Flash Grade (Boiling Point between
130-144ºF) with a minimum purity of 97%.
Background:
In 1924, an Atlanta dry cleaner named W. J. Stoddard worked with
Lloyd E. Jackson of the Mellon Research Institute to develop specifications
for a less volatile dry cleaning solvent as an alternative to more volatile
petroleum solvents. Dry cleaners began using it in 1928 and it was the
predominant dry cleaning solvent in the United States from the late 1920s
until the late 1950s when it was replaced with perchloroethylene.
Uses:
Artists use mineral spirits as an alternative to turpentine, one that is both
less flammable and less toxic. For this purpose, this particular solvent is
further refined to remove sulfur and the more toxic aromatic compounds,
and is recommended for critical applications such as oil painting.
It is commonly used as an extraction solvent, as a cleaning solvent, as a
degreasing solvent and as a solvent in aerosols, paints, wood preservatives,
lacquers, varnishes, and asphalt products. It is the most widely used solvent
in the paint industry.
In industry it is used for cleaning and degreasing machine tools and parts.
It is especially effective in removing oils, greases, carbon, and other materials
from metals. It may also be used in conjunction with cutting oil as a thread
cutting and reaming lubricant.
In screen printing (also referred to as silk-screening), mineral spirits are often
used to clean and unclog screens after printing with oil-based textile and plastisol
inks.
General Application Notes:
Four different types and three different grades of Stoddard Solvent exist.
The type refers to the purification process used. Type 0, is defined as
the distillation fraction with no further treatment to hydrodesulfurization
(removal of sulfur) alone (type 1), solvent extraction (type 2) or hydrogenation
(type 3). Each type comprises three different grades: low flash grade, regular
grade, and high flash grade. The grade is determined by the crude oil used as
the starting material and the conditions of distillation.
Precautions:
Flammable, moderate fire risk. Toxic by ingestion, inhalation
and skin absorption. It is mainly classed as an irritant. It has a fairly
low acute toxicity by inhalation of the vapor, skin contact and ingestion.
However, acute exposure can lead to central nervous system depression
resulting in lack of coordination and slowed reactions. Exposure to very
high concentrations in enclosed spaces can lead to general narcotic effects
(drowsiness, dizziness, nausea etc...) and can eventually lead to unconsciousness.
Prolonged or repeated skin exposure over a long period of time can result
in severe irritant dermatitis, also called contact dermatitis. It is highly
recommended that skin exposure is kept to a minimum by use of gloves
and that hands are washed after coming into contact with it. Occasional
exposure to skin is highly unlikely to cause any problems.
Owing to the volatility and low bioavailability of its constituents, white
spirit, though moderately toxic to aquatic organisms, is unlikely to present
significant hazards to the environment. It should not however, be purposely
poured down the sink or freshwater drain if avoidable. It should be disposed
of correctly wherever possible.
