Castor oil is a vegetable oil pressed from castor beans, the seeds of the plant Ricinus communis. [1] The seeds are 40 to 60 percent oil. [ 2 ] It is a colourless or pale yellow liquid with a distinct taste and odor.
Top 5 oil-producing countries 1980–2022 World oil production. This is a list of countries by oil production (i.e., petroleum production), as compiled from the U.S. Energy Information Administration database for calendar year 2023, tabulating all countries on a comparable best-estimate basis.
A smaller unit of kilogram of oil equivalent (kgoe or koe) is also sometimes used denoting 1/1000 toe. A related concept is the physical quantity oil-equivalent mass (or mass of oil equivalent ), [ 1 ] [ 2 ] expressed in the ordinary units of mass and its multiples: kilogram (kg), megagram (Mg) or tonne (t), etc.
The medium, base, or vehicle is the mixture to which the dry pigment is added. Different media can increase or decrease the rate at which oil paints dry. Often, because a paint is too opaque, painters will add a medium like linseed oil or alkyd to the paint to make them more transparent and pliable for the purposes of glazing.
An oil drying agent, also known as siccative, is a coordination compound that accelerates the hardening of drying oils, often as they are used in oil-based paints. This so-called "drying" (actually a chemical reaction that produces an organic plastic) occurs through free-radical chemical crosslinking of the oils.
Ricin (/ ˈ r aɪ s ɪ n / RY-sin) is a lectin (a carbohydrate-binding protein) and a highly potent toxin produced in the seeds of the castor oil plant, Ricinus communis.The median lethal dose (LD 50) of ricin for mice is around 22 micrograms per kilogram of body weight via intraperitoneal injection.
Zinc ricinoleate is the zinc salt of ricinoleic acid, a major fatty acid found in castor oil.It is used in many deodorants as an odor-adsorbing agent. The mechanism of this activity is unclear.
Metric regions commonly use the tonne of oil equivalent (toe), or more often million toe (Mtoe). Since this is a measurement of mass, any conversion to barrels of oil equivalent depends on the density of the oil in question, as well as the energy content. Typically 1 tonne of oil has a volume of 1.08 to 1.19 cubic metres (6.8 to 7.5 bbl).
