Re: Need a new solvent ASAP!
- As a chemist and an employee of the petroleum industry for 30+ years, I can tell you that all of these terms are pretty broad. Their specs will vary somewhat from company to company. Naphtha is generally not close to white gas. One of the important items is the flash point, the temperature at which vapors will ignite if exposed to an ignition source. Mineral spirits generally runs in the 100 F range which means that it is fairly safe in most working environments. It will burn if exposed to a flame because that flame will raise its temperature above the flash point. These products are generally of low volatility which yields another safety factor, and enables them to remain on the surface being cleaned longer than faster solvents. Solvency of ink is, of course, important. Try a little of it and see if it meets your requirements. These solvents will disolve the natural oils from your skin and in some cases may caust dermititis. The severity depends upon each individuals susceptibility, and the degree of exposure. Don't take a bath in it. I've used it many years with no problem.
Now for the waiver: I am not familiar with California regulations, and do not know what they may have forced manufacturers to change in these products. Otherwise, this applies in most of the rest of the world.

There seem to be a number of these off brand "green" solvents slipping past the censors. No ingredients listing, no MSDS supplied. Available in stores and on line. Very strange considering the strict regulations imposed on known manufacturers.
