The aniline point measure of the ability of the base oil to act as a solvent and is determined from the temperature at which equal volumes of aniline and the base stock are soluble High aniline points (approximately 100°C or greater) imply a paraffinic base stock, while low aniline points (less than 100°C) imply a naphthenic or aromatic stock.
The K factor or characterization factor is defined from Rankine boiling temperature °R=1.8Tb[k] and relative to water density ρ at 60°F: . K(UOP) = / The K factor is a systematic way of classifying a crude oil according to its paraffinic, naphthenic, intermediate or aromatic nature. 12.5 or higher indicate a crude oil of predominantly paraffinic constituents, while 10 or lower indicate a ...
Liquid paraffin, also known as paraffinum liquidum, paraffin oil, liquid paraffin oil or Russian mineral oil, is a very highly refined mineral oil used in cosmetics and medicine. Cosmetic or medicinal liquid paraffin should not be confused with the paraffin (i.e. kerosene ) used as a fuel.
Naphtha (/ ˈ n æ f θ ə /, recorded as less common or nonstandard [1] in all dictionaries: / ˈ n æ p θ ə /) is a flammable liquid hydrocarbon mixture.Generally, it is a fraction of crude oil, but it can also be produced from natural-gas condensates, petroleum distillates, and the fractional distillation of coal tar and peat.
Wound healing. Research has found that oral supplementation of vitamin E (along with vitamin C and zinc) has a positive effect on reduced wound healing time. However, when it comes to topical ...
Petroleum jelly, petrolatum (/ ˌ p ɛ t r ə ˈ l eɪ t ə m /), white petrolatum, soft paraffin, or multi-hydrocarbon, CAS number 8009-03-8, is a semi-solid mixture of hydrocarbons (with carbon numbers mainly higher than 25), [1] originally promoted as a topical ointment for its healing properties. [2] Vaseline has been an American brand of ...
In the event of an injury that damages the skin's protective barrier, the body triggers a response called wound healing. After hemostasis, inflammation white blood cells, including phagocytic macrophages arrive at the injury site. Once the invading microorganisms have been brought under control, the skin proceeds to heal itself.
The most common one is a type of paraffinic crude oil, although there are also naphthenic crude oils that create products with better solubility and very good properties at low temperatures. By using hydrogenation technology, in which sulfur and aromatics are removed using hydrogen under high pressure, extremely pure base oils can be obtained ...
