• Beschreibung

  Paraffin wax, also commonly called ‘paraffin’, is a colourless or white, tasteless, odourless, translucent waxy solid. Paraffin wax has a typical melting point between about 46°C and 68°C. Pure paraffin wax is a combustible substance and insoluble in water but soluble in petroleum solvents and stable under normal conditions of use. Paraffin has been identified as an excellent electrical insulator. It is also used in the manufacturing of paraffin papers, candles, food packaging materials, varnishes, floor polishes, to extract perfumes from flowers, in lubricants, and cosmetics. It is also used in water-proofing wood, and cork.

• Chemische Eigenschaften

  Paraffin wax is colorless or white with an odorless mass. It consists of a mixture of solid aliphatic hydrocarbons. Paraffin is used in the manufacture of paraffin papers, candles, food packaging materials, varnishes, floor polishes, to extract perfumes from flowers, in lubricants, and cosmetics. It is also used in waterproofing wood and cork.

• Verwenden

  Paraffin Wax is used to embed tissues to be used in research.

• Verwenden

  Paraffin wax, or hard wax, is a mixture of solid hydrocarbons, mainly alkanes. Paraffinwaxcan beadded to medicinal agents. Petroleumwax and petrolatum are the only hydrocarbons permitted for use in food products. Paraffin wax is used as a household wax and extensively as a coating for food containers and wrappers.

• Verwenden

  Paraffin wax can be used as a phase changing material in a wide range of applications which include solar based water heaters, microcapsules and thermal energy devices (TEDs).

• Definition

  A solid mixture of hydrocarbons, obtained from petroleum.

• Vorbereitung Methode

  Paraffin is manufactured by the distillation of crude petroleum or shale oil, followed by purification by acid treatment and filtration. Paraffins with different properties may be produced by controlling the distillation and subsequent congealing conditions.
  Synthetic paraffin, synthesized from carbon monoxide and hydrogen is also available;

• Allgemeine Beschreibung

  White translucent tasteless odorless solids. Density 0.88- 0.92 g / cm3. Insoluble in water. Melting range 47-65°C. Used in candles, lubricants, crayons, floor polishes, cosmetics, chewing gum.

• Air & Water Reaktionen

  Insoluble in water.

• Reaktivität anzeigen

  Paraffin wax, may be incompatible with strong oxidizing agents. Charring may occur followed by ignition of unreacted portion and other nearby combustibles. In other settings, mostly unreactive. Not affected by aqueous solutions of acids, alkalis, most oxidizing agents, and most reducing agents. When heated sufficiently or when ignited in the presence of air, oxygen or strong oxidizing agents, they burn exothermically.

• Health Hazard

  Exposures to paraffi n for a prolonged period cause several types of skin disorders, The adverse health effects to skin include chronic dermatitis, wax boils, folliculitis, comedones, papules, melanoderma, and hyperkeratoses. Studies of Hendricks et al. indicated the development of carcinoma of the scrotum in workers exposed to crude petroleum wax. Carcinoma of the scrotum in occupational workers began with a normal hyperkeratotic nevus-like lesion, which subsequently resulted in a squamous cell carcinoma.

• Flammability and Explosibility

  Not classified

• Pharmazeutische Anwendungen

  Paraffin is mainly used in topical pharmaceutical formulations as a component of creams and ointments. In ointments, it may be used to increase the melting point of a formulation or to add stiffness. Paraffin is additionally used as a coating agent for capsules and tablets, and is used in some food applications. Paraffin coatings can also be used to affect the release of drug from ion-exchange resin beads.

• Sicherheitsprofil

  A skin and eye irritant. Questionable carcinogen with experimental tumorigenic data by implant route. Many paraffin waxes contain carcinogens. Fumes cause lung damage. See also PARAFFIN HYDROCARBONS.

• Sicherheit(Safety)

  Paraffin is generally regarded as an essentially nontoxic and nonirritant material when used in topical ointments and as a coating agent for tablets and capsules. However, granulomatous reactions (paraffinomas) may occur following injection of paraffin into tissue for cosmetic purposes or to relieve pain. Long-term inhalation of aerosolized paraffin may lead to interstitial pulmonary disease. Ingestion of a substantial amount of white soft paraffin has led to intestinal obstruction in one instance.

• Synthese

  Synthesized by the Fischer–Tropsch process from carbon monoxide and hydrogen, which are catalytically converted to a mixture of paraffin hydrocarbons. The lower molecular weight fractions are removed by distillation and the residue is hydrogenated and further treated by percolation through activated charcoal.

• Lager

  Paraffin is stable, although repeated melting and congealing may alter its physical properties. Paraffin should be stored at a temperature not exceeding 40°C in a well-closed container.

• Filter für giftige stoffe

  The initial threshold screening level (ITSL) for paraffin wax fume is 20 μg/m3 based on an 8 hr.averaging time.

• Regulatory Status

  Accepted in the UK for use in certain food applications. Included in the FDA Inactive Ingredients Database (oral capsules and tablets, topical emulsions, and ointments). Included in nonparenteral medicines licensed in the UK. Included in the Canadian List of Acceptable Non-medicinal Ingredients.
