An oil is any nonpolar chemical substance that is composed primarily of hydrocarbons and is hydrophobic (does not mix with water) and lipophilic (mixes with other oils). Oils are usually flammable and surface active. Most oils are unsaturated lipids that are liquid at room temperature. The general definition of oil includes classes of chemical ...
Petroleum or crude oil, also referred to as simply oil, is a naturally occurring yellowish-black liquid mixture of mainly hydrocarbons, [1] and is found in geological formations. The name petroleum covers both naturally occurring unprocessed crude oil and petroleum products that consist of refined crude oil. Petroleum is primarily recovered by ...
Synthetic oil is a lubricant consisting of chemical compounds that are artificially modified or synthesised. Synthetic lubricants can be manufactured using chemically modified petroleum components rather than whole crude oil, but can also be synthesized from other raw materials. The base material, however, is still overwhelmingly crude oil that ...
Consists of synthetic oils made of Poly-internal-olefins (PIO). Poly-internal-olefins (PIO) oils are similar to Poly-alpha-olefins , but use different chemicals in the synthesis process to obtain an even higher viscosity index (VI) See also. Mineral oil, a broader term that encompasses many base oils. This term usually refers to the domestic or ...
Mineral oil is a common ingredient in baby lotions, cold creams, ointments, and cosmetics. It is a lightweight inexpensive oil that is odorless and tasteless. It can be used on eyelashes to prevent brittleness and breaking and, in cold cream, is also used to remove creme make-up and temporary tattoos.
The production process of vegetable oil involves the removal of oil from plant components, typically seeds. This can be done via mechanical extraction using an oil mill or chemical extraction using a solvent. The extracted oil can then be purified and, if required, refined or chemically altered. Mechanical extraction
Palm oil is an edible vegetable oil derived from the mesocarp (reddish pulp) of the fruit of oil palms. [1] The oil is used in food manufacturing, in beauty products, and as biofuel. Palm oil accounted for about 36% of global oils produced from oil crops in 2014. [2] Palm oils are easier to stabilize and maintain quality of flavor and ...
U.S. olive oil is a mixture of virgin and refined oils; U.S. refined olive oil is an oil made from refined oils with some restrictions on the processing. These grades are voluntary. Certification is available, for a fee, from the USDA. In 2014, California adopted a set of olive oil standards for olive oil made from California-grown olives.
