Highly refined paraffinic oils

These highly refined paraffinic oils are also used in agriculture sprays, coatings, textile specialties, sports equipment, footwear, dust control, white oil feedstock, paper and pulp process defoamers, insecticide carriers, and caulking and sealant compounds. 

Technical and Food Grade White Oils and Highly Refined Paraffins... 

One of the most important requirements to produce quality methyl ester sulphonate is the use of a high quality methyl ester feedstock. The best of the feedstocks currently used are highly refined palm oil derivatives. These feedstocks have low acid values, a narrow molecular weight distribution, contain little or no paraffinic compounds and have been extensively hydrogenated to reduce their iodine value to a very low value (less than 0.5). The latter is essential because high iodine values indicate the presence of double bonds in the feedstock which will result in dark coloured products upon sulphonation. 

In the latter part of the nineteenth century, workers in the paraffin refining, shale oil, and coal tar industries had high incidences of skin cancer. A possible cause emerged during the period 1915-1918 when Japanese scientists discovered that painting the ears of rabbits and mice with coal tar extracts produced tumors, some of which were malignant (Yamagiwa and Ichikawa, 1918). 

Medicinal oil highly refined, colorless, tasteless, and odorless petroleum oil used as a medicine in the nature of an internal lubricant sometimes called liquid paraffin. 

As with conventional emulsions the nature of the oil can affect the behaviour of the system. For pharmaceutical uses, oils used include the refined hydrocarbon oils such as light liquid paraffin and esters of long-chain fatty acids including vegetable oils, for example, ethyl oleate and isopropyl myristate, olive oil and sesame oil. Frankenfeld et al (SO used mixtures of Solvent 100 Neutral (an isoparaffinic, dewaxed oil of high viscosity) and Norpar 13 (a non-viscous, normal paraffinic solvent) to vary the viscosity of the oil phase in attempts to control the transfer of solutes across the oil membrane. 

Describes the processing methods and the chemistry behind highly refined Food Grade white oils and paraffins... 

Paraffinic oils contain not only high levels of naphthenic rings but also higher levels of alkyl pendant groups, unsaturated hydrocarbon pendant groups, and, most important, fewer naphthenic groups per molecule. Pure paraffins from refined petroleum condense out as wax. 

Unocal Hydrocarbon Sales Mineral Seal oil is a highly refined, hydrotreated paraffinic light oil that is water-white in appearance. Properties include a very low odor, low aromatic content and low pour point. This product meets 21CFR178.3620(c). 

The V.G.C. ranges from about 0.8 for highly paraffinic oils to about 0.95 for highly aromatic. Although originally developed for classifying crude oils, it is also used for refined products. It is an additive property for mixtures but shows no direct or simple relationship to V.I.
