After two days, the treated leather was polished with a soft cloth. Hard leathers can be soaked in a solution of one part British Museum leather dressing: three parts Stoddard solvent. [4] British Museum leather dressing darkens leather, but it is a treatment with a good success record. [3] [4]
Stoddard solvent is a specific mixture of hydrocarbons, typically over 65% C 10 or higher hydrocarbons, [4] developed in 1924 by Atlanta dry cleaner W. J. Stoddard and Lloyd E. Jackson of the Mellon Institute of Industrial Research as a less flammable petroleum-based dry cleaning solvent than the petroleum solvents then in use.
Techron consists of five components: [3] [failed verification] Distillates, hydrotreated light at 40-70% weight; Stoddard solvent at 15-40% weight; Solvent naphtha (petroleum), light aromatic at 5-10% weight; 1,2,4-trimethylbenzene at 1-5% weight; Polyetheramine (PEA) , polyether amines at 20-49% weight
In the United Kingdom, the environmental regulator permits only chemical additives which are classed as non hazardous to groundwater for fracturing fluids. [3] [4] [5] Operators are required to disclose the content of hydraulic fracturing fluids to the relevant environment agency [6] while the composition must be disclosed if the regulator demands it.

This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.
The result of this test is a scaleless index, usually referred to as the "Kb value". A higher Kb value means the solvent is more aggressive or active in the ability to dissolve certain materials. Mild solvents have low scores in the tens and twenties; powerful solvents like chlorinated solvents and naphthenic aromatic solvents (i.e. "High Sol ...
Marvel Mystery Oil logo. Marvel Mystery Oil is an automotive product of the American Marvel Oil Company, [1] founded by Burt Pierce in 1923. [2] It is used as a fuel additive and oil additive, purportedly to function as a corrosion inhibitor, penetrating oil, transmission leak stopper and seal relubricator, despite a lack of scientific evidence supporting such claims.
Solvent degreasing is a process used to prepare a part for further operations such as electroplating or painting. Typically it uses petroleum , chlorine , dry ice or alcohol based solvents to dissolve the machining fluids and other contaminants that might be on the part.
