Mineral Oil CAS#8042-47-5

Products Description of Mineral oil CAS#8042-47-5Mineral Oil (CAS#8042-47-5) is a highly refined petroleum distillate that is colorless to pale yellow in appearance, with a clear and viscous texture. It is essentially odorless, with a specific gravity ranging from 0.79 to 0.94 at 15.6 °C, and a boiling point that varies widely, typically between 150–894 °C. Mineral oil has a low vapor pressure, which is less than 0.1 kPa at 20 °C, and a flash point of 168.33 °C. It is insoluble in water and has a molecular weight ranging from approximately 28.2 to 843.6 g/mol, with the number of carbon atoms in the compounds present in mineral oil ranging from C9 to C60 .

Mineral oil is not a single substance but a mixture of hydrocarbons isolated from crude petroleum oil. It comprises three main types of compounds: saturated paraffins, napthenes, and aromatics. Saturated paraffins are linear and branched hydrocarbons with single bonds, while napthenes include single bonds and rings, which may also have alkyl groups extending from these structures. Aromatic compounds in mineral oil are cyclic hydrocarbons with carbon-carbon double bonds, but these are limited to the aromatic ring portions of the chemical structure .

Mineral oil is used in a variety of applications due to its inert, non-toxic nature. It is used in the food industry as a release agent, binder, or lubricant, and in medical applications, it is used as a laxative for both humans and animals. In livestock production, it is used to treat colic, constipation, and impactions within the digestive tract. The FDA has designated white mineral oil as a substance that "may be safely used in food" and is permitted for use in various food applications .

Mineral oil is considered non-toxic in the environment, with a short aquatic lifetime of 2–3 days and a longer lifetime in soil where it undergoes slow biodegradation. It is not considered to bioaccumulate and is of low acute toxicity to plants and animals . However, it is important to note that environmental contamination may occur during the extraction and transportation of crude oil, as well as during the refining process if proper handling procedures are not followed .
