Question: What type of mixture is Vaseline?

full_context: Document 1: Pennsylvania Grade Crude Oil: Pennsylvania Grade Crude Oil is a type of sweet crude oil (sweet crude oil), found primarily in the Appalachian basin in the Marcellus Formation in the states of New York, Pennsylvania, Ohio, and West Virginia, and takes its name for the state of Pennsylvania, where it was first extracted in 1859 from the Drake Well. The area's Pennsylvania Grade Crude Oil has superior qualities and is free of asphaltic constituents, contains only trace amounts of sulfur and nitrogen, and has excellent characteristics for refining into lubricants. The success of drilling for oil at this well led to "an international search for petroleum, and in many ways eventually changed the way we live." There is archaeological evidence that Native Americans harvested "the oil for medicinal purposes by digging small pits around active seeps and lining them with wood" at least as far back as 1410 AD. European settlers skimmed the "oil from the seeps and using the petroleum as a source of lamp fuel and machinery lubrication."
Document 2: Pitch drop experiment: The pitch drop experiment is a long-term experiment that measures the flow of a piece of pitch over many years. Pitch is the name for any of a number of highly viscous liquids that appear solid, most commonly bitumen. At room temperature, tar pitch flows at a very low rate, taking several years to form a single drop.
Document 3: Cyclopentane: Cyclopentane is a highly flammable alicyclic hydrocarbon with chemical formula CH and CAS number 287-92-3, consisting of a ring of five carbon atoms each bonded with two hydrogen atoms above and below the plane. It occurs as a colorless liquid with a petrol-like odor. Its melting point is −94 °C and its boiling point is 49 °C. Cyclopentane is in the class of cycloalkanes, being alkanes that have one or more rings of carbon atoms.
Document 4: Hair wax: Hair wax is a thick hairstyling product containing wax, used to assist with holding the hair. In contrast with hair gel, most of which contain alcohol, hair wax remains appliable and has less chance of drying out. Consequently, hair wax is currently experiencing an increase in popularity, often under names such as pomade, putty, glue, whip, molding gum, or styling paste. The texture, consistency, and purpose of these products varies widely and each has a different purported purpose depending on the manufacturer. Traditionally, pomade is a type of hair wax that also adds shine to one's hair.
Document 5: Pomade: Pomade ( ; French "pommade") is a greasy, waxy, or a water-based substance that is used to style hair. Pomade gives the user's hair a shiny, slick appearance, and does not dry it out. It lasts longer than most hair care products, often requiring multiple washes to completely remove. The original pomade of the eighteenth and nineteenth centuries consisted mainly of bear fat or lard. Lanolin, beeswax, and petroleum jelly have been used extensively in the manufacture of modern pomades. Stiffening properties of pomades make sculptured hairstyles such as the pompadour or quiff possible; while long lasting moisturizing properties make it popular with individuals with Afro-textured hair.
Document 6: Sweet crude oil: Sweet crude oil is a type of petroleum. The New York Mercantile Exchange designates petroleum with less than 0.42% sulfur as "sweet". Petroleum containing higher levels of sulfur is called sour crude oil.
Document 7: Hexadecane: Hexadecane (also called cetane) is an alkane hydrocarbon with the chemical formula CH. Hexadecane consists of a chain of 16 carbon atoms, with three hydrogen atoms bonded to the two end carbon atoms, and two hydrogens bonded to each of the 14 other carbon atoms.
Document 8: Light crude oil: Light crude oil is liquid petroleum that has a low density and flows freely at room temperature. It has a low viscosity, low specific gravity and high API gravity due to the presence of a high proportion of light hydrocarbon fractions. It generally has a low wax content. Light crude oil receives a higher price than heavy crude oil on commodity markets because it produces a higher percentage of gasoline and diesel fuel when converted into products by an oil refinery.
Document 9: Petroleum benzine: Petroleum benzine is a hydrocarbon based solvent mixture that is classified by its physical properties (e.g. boiling point, vapor pressure) rather than a specific chemical composition, often obfuscating distinction within the long list of petroleum distillate solvent mixtures: mineral spirits, naphtha, white spirits, petroleum spirits, turps substitute, mineral turpentine, petroleum benzine, petroleum ether, ligroin, and Stoddard Solvent. The chemical composition of a petroleum distillate can also be modified to afford a solvent with reduced concentration of unsaturated hydrocarbons, "i.e." alkenes, by hydrotreating and/or reduced aromatics, "e.g." benzene, toluene xylene, by several dearomatization methods. In a document that attempts to draw more concise distinctions between hydrocarbon solvents, conservator Alan Phenix explains that the most important distinction amongst the various hydrocarbon solvents are their boiling/distillation ranges (and, by association, volatility, flash point etc.) and aromatic content. Given the toxicity/carcinogenicity of some aromatic hydrocarbons, most notably benzene, the aromatic content of petroleum distillate solvents, which would normally be in the 10-25% (w/w) range for most petroleum fractions, can be advantageously reduced when their special solvation properties are not required and a less odorous, lower toxicity solvent is desired, especially when present in consumer products. Phenix further points out that "To all intents and purposes petroleum benzine appears synonymous with petroleum spirit." Petroleum spirit is generally considered to be the fractions between the very lightest hydrocarbons, petroleum ether, and the heavier distillates, mineral spirits. For example, petroleum benzine with a boiling range of 36 - 83 °C sold by EMD Millipore under CAS-No. 64742-49-0 is identified in the product MSDS as hydrotreated light petroleum distillates comprising ≥ 90% C5-C7 hydrocarbons, n-alkanes, isoalkanes, and < 5% n-hexane, while Santa Cruz Biotechnology sells a petroleum ether product under the same CAS-No. Fisher Scientific offers a product ‘Benzine (Petroleum Naphtha)' that retails for a high price that would suggest it is a speciality product but in fact conforms to Marathon Petroleum's 'VM&P Naphtha' (Varnish Makers & Painters’ Naphtha) found widely distributed in many hardware stores in North America.
Document 10: Petroleum jelly: Petroleum jelly, petrolatum, white petrolatum, soft paraffin/paraffin wax or multi-hydrocarbon, CAS number 8009-03-8, is a semi-solid mixture of hydrocarbons (with carbon numbers mainly higher than 25), originally promoted as a topical ointment for its healing properties.
Document 11: Grease (lubricant): Grease is a semisolid lubricant. Grease generally consists of a soap emulsified with mineral or vegetable oil. The characteristic feature of greases is that they possess a high initial viscosity, which upon the application of shear, drops to give the effect of an oil-lubricated bearing of approximately the same viscosity as the base oil used in the grease. This change in viscosity is called shear thinning. Grease is sometimes used to describe lubricating materials that are simply soft solids or high viscosity liquids, but these materials do not exhibit the shear-thinning properties characteristic of the classical grease. For example, petroleum jellies such as Vaseline are not generally classified as greases.

Document 13: Kelvin–Voigt material: A Kelvin–Voigt material, also called a Voigt material, is a viscoelastic material having the properties both of elasticity and viscosity. It is named after the British physicist and engineer Lord Kelvin and after German physicist Woldemar Voigt.
Document 14: Shea butter: Shea butter ( , , or ) is a fat extracted from the nut of the African shea tree ("Vitellaria paradoxa"). It is usually yellow in color when raw, with Unrefined, refined, and Ultra-Refined Shea butter being ivory or white in color. Shea butter is a triglyceride (fat) derived mainly from stearic acid and oleic acid. It is widely used in cosmetics as a moisturizer, salve or lotion. Shea butter is edible and is used in food preparation in Africa. Occasionally, the chocolate industry uses shea butter mixed with other oils as a substitute for cocoa butter, although the taste is noticeably different.
Document 15: Murray's Pomade: Murray's Pomade, or Murray's Superior Pomade, or just Murray's, is a hair pomade developed in 1925. Since then, Murray's remains a popular pomade in drug stores and grocery stores. Murray's is an oil based pomade, with ingredients petroleum, mineral oil and fragrance. Original Murrays has a very thick and waxy consistency.
