Σπύρο, εγώ νομίζω ότι mineral oil είναι το παραφινέλαιο.

Ας το αφήσουμε αυτό για το paraffin oil.

In chemistry, paraffin is the common name for the alkane hydrocarbons with the general formula CnH2n+2. Paraffin wax refers to the solids with 20 ≤ n ≤ 40 .

The simplest paraffin molecule is that of methane, CH4, a gas at room temperature. Heavier members of the series, such as that of octane, C8H18, and mineral oil appear as liquids at room temperature. The solid forms of paraffin, called paraffin wax, are from the heaviest molecules from C20H42 to C40H82. Paraffin wax was identified by Carl Reichenbach in 1830.[1]

Paraffin, or paraffin hydrocarbon, is also the technical name for an alkane in general, but in most cases it refers specifically to a linear, or normal alkane — whereas branched, or isoalkanes are also called isoparaffins. It is distinct from the fuel known in Ireland, Britain and South Africa as paraffin oil or just paraffin, which is called kerosene in most of the U.S., Canada, Australia and New Zealand.

The name is derived from the Latin parum (= barely) + affinis with the meaning here of "lacking affinity", or "lacking reactivity".[2] This is because alkanes, being non-polar and lacking in functional groups, are very unreactive.

Mineral oil or liquid petroleum is a by-product in the distillation of petroleum to produce gasoline and other petroleum based products from crude oil. It is a transparent, colorless oil composed mainly of alkanes (typically 15 to 40 carbons) and cyclic paraffins, related to petroleum jelly (also known as "white petrolatum"). It has a density of around 0.8 g/cm3.[1] Mineral oil is a substance of relatively low value, and it is produced in very large quantities. Mineral oil is available in light and heavy grades, and can often be found in drug stores.

In the late 1800s, the term "mineral oil" or "rock oil" was first used to describe the petroleum hydrocarbons and associated products that were produced from wells that tapped underground reservoirs. The term differentiated petroleum hydrocarbons produced from underground sources from other common oil sources at the time, such as palm oil or whale oil. In today's petroleum exploration and production (E&P) business, the phrase "mineral oil" is most often used in legal documents to define and encompass all of the liquid hydrocarbon and gaseous products produced from wells drilled into underground petroleum-bearing reservoirs.

There are three basic classes of refined mineral oils:

    * paraffinic oils, based on n-alkanes
    * naphthenic oils, based on cycloalkanes
    * aromatic oils, based on aromatic hydrocarbons (not to be confused with essential oils)

Βίκυ, νομίζω ότι στην επικεφαλίδα πρέπει να μπει και το παραφινέλαιο, ανεξάρτητα εάν ονομάζεται και paraffin oil.

Και βλέπω και «ορυκτό λάδι / ορυκτέλαιο / πετρελαιοειδές / μεταλλικά έλαια» στο ΙΑΤΕ.
