In the United States, the Occupational Safety and Health Administration has set the legal limit for mineral oil mist exposure in the workplace as 5 mg/m 3 (0.0022 gr/cu ft) over an 8-hour workday, the National Institute for Occupational Safety and Health has set a recommended exposure limit of 5 mg/m 3 (0.0022 gr/cu ft) over an 8-hour workday, with a previous limit of 10 mg/m 3 (0.0044 gr/cu ft) for short-term exposure rescinded according to the 2019 Guide to Occupational Exposure Values compiled by the ACGIH. People can be exposed to mineral oil mist in the workplace through inhalation, skin contact, or eye contact. The FSA did not identify any specific food safety concerns due to inks. The UK Food Standards Agency (FSA) carried out a risk assessment on the migration of components from printing inks used on carton-board packaging-including mineral oils-into food in 2011, based on the findings of a survey conducted in the same year. The World Health Organization classifies minimally treated mineral oils as carcinogens group 1 known to be carcinogenic to humans Highly refined oils are classified group 3 as not suspected to be carcinogenic, from known available information sufficient to classify them as harmless. In lubrication, mineral oils make up Group I, II, and III base oils that are refined from petroleum. British aromatherapists commonly use the term "white mineral oil". The term "paraffinum liquidum" is often seen on the ingredient lists of baby oil and cosmetics. Instead, British pharmacologists use the terms "paraffinum perliquidum" for light mineral oil and "paraffinum liquidum" or "paraffinum subliquidum" for somewhat more viscous varieties. "Mineral oil", sold widely and cheaply in the United States, is not sold as such in the United Kingdom. A similar lexical situation occurred with the term " white metal". Prior to the late 19th century, the chemical science to determine the makeup of an oil was unavailable in any case. Merriam-Webster states the first use of the term "mineral oil" as being 1771. Some of the imprecision in the definition of the names used for mineral oil (such as 'white oil') reflects usage by consumers and merchants who did not know, and usually had no need of knowing, the oil's precise chemical makeup. More generally, mineral oil is a transparent, colorless oil, composed mainly of alkanes and cycloalkanes, related to petroleum jelly. Mineral oils used for lubrication are known specifically as base oils. Most often, mineral oil is a liquid obtained from refining crude oil to make gasoline and other petroleum products. Other names, similarly imprecise, include 'white oil', 'paraffin oil', ' liquid paraffin' (a highly refined medical grade), paraffinum liquidum ( Latin), and 'liquid petroleum'. The name 'mineral oil' by itself is imprecise, having been used for many specific oils over the past few centuries. Mineral oil is any of various colorless, odorless, light mixtures of higher alkanes from a mineral source, particularly a distillate of petroleum, as distinct from usually edible vegetable oils.
