Check washing process of washing a check is relatively simple and can be accomplished with basic solvents. The actual solvent is largely irrelevant — more importantly, the polarity of the solvent must match the polarity of the dye in the ink. For example, an ink that is mostly made of a polar dye would require a polar solvent (e.g. acetone or isopropanol). Both nail polish remover (acetone) and rubbing alcohol (isopropanol) are able to pull most common inks away from paper in minutes. Similarly, a non-polar dye would require a non-polar solvent (e.g. toluene or a similar hydrocarbon). Check washing Check washing
Cosmetology products containing chemicals. "Hair dyes represent the largest segment of chemical products in the hair market today. As such, they are the main source of chemical exposure among hairdressers". Toluene is a clear, water insoluble liquid with a distinct and pungent smell, similar to paint thinners. Toluene is found in cosmetic products like nail polish, nail glue, and hair dyes and is widely used as an industrial solvent and is used to make fingernail polishes, lacquers, adhesives, rubber, and paint thinners. It is used in the production of benzene, gasoline, nylon, plastics, and polyurethane. Toluene can be found on cosmetic
