Some substance identifiers may have been claimed confidential, or may not have been provided, and therefore not be displayed. The examples provided are generic examples and may not apply to the specific substance you are viewing. The molecular formula identifies each type of element by its chemical symbol and identifies the number of atoms of each element found in one discrete molecule of the substance. The Prior Informed Consent Regulation administers the import and export of certain hazardous chemicals and places obligations on companies who wish to export these chemicals to non-EU countries. A substance may have its use restricted to certain articles or products and therefore not all the examples may apply to the specific substance. Under standard conditions of temperature and pressure (STP), the first four members of the alkane series (methane, ethane, propane, and butane) are in gaseous form, and compounds starting from C5H12 (pentane) to n-heptadecane (C17H36) are liquids (constituting large fractions of hydrocarbons found in liquid fuels (e.g., gasoline, jet fuel, and diesel fuel), whereas n-octadecane (C18H38) or heavier compounds exist in isolation as wax-like solids at STP. The REACH registered substance data and the C&L Inventory portal will be upgraded from the 9th November. The ‘Hazard classification and labelling’ section shows the hazards of a substance based on the standardised system of statements and pictograms established under the CLP (Classification Labelling and Packaging) Regulation. Normal paraffins or normal alkanes are simply written as n-paraffins or n-alkanes, and they are open, straight-chain saturated hydrocarbons. This substance has not been registered under the REACH Regulation, therefore as yet ECHA has not received any data about this substance from registration dossiers. Paraffin hydrocarbon, also called alkane, any of the saturated hydrocarbons having the general formula CnH2n+2, C being a carbon atom, H a hydrogen atom, and n an integer. In that case, the ATP (Adaptation to Technical Progress) number is displayed. cooling liquids in refrigerators, oil-based electric heaters) and outdoor use in close systems with minimal release (e.g. Release to the environment of this substance can occur from industrial use: in processing aids at industrial sites, of substances in closed systems with minimal release, manufacturing of the substance and formulation of mixtures. It is transparent, colorless, nearly odorless, and oily and is composed of saturated hydrocarbons derived from petroleum. The ‘Hazard classification’ and labelling section uses the signal word, pictogram(s) and hazard statements of the substance under the harmonised classification and labelling (CLH) as its primary source of information. ECHA has no public registered data on the routes by which this substance is most likely to be released to the environment. It does not represent a new labelling, classification or hazard statement, neither reflect other factors that affect the susceptibility of the effects described, such as duration of exposure or substance concentration (e.g. Hazard statements were adapted to improve readability and may not correspond textually to the hazard statements codes description in the European Union Specific Hazard Statements (EUH) or the. This substance is used by consumers, by professional workers (widespread uses), in formulation or re-packing, at industrial sites and in manufacturing. Guidance on safe use - recommendations by substance registrant on the proper use of the substance in various situations. Figure 1.9. What are the disadvantages of primary group? Substances indicated, in 2009, as being intended to be registered by at least one company in the EEA. Paraffins are … The described Product category (i.e. inside a watch) or with very low concentrations considered not to pose risks to human health or the environment. Precautionary statements - describe recommended measures to minimise or prevent adverse effects resulting from exposure to a hazardous product or improper storage or handling of a hazardous product. For the benefit of those who do not know, in chemistry, paraffin is the common name for the alkane hydrocarbons with the general formula CnH2n+2. This substance is used in the following products: laboratory chemicals, lubricants and greases and metal working fluids. How do you put grass into a personification? Normal and isoparaffins (as isomers) and the effect of molecular structure on boiling points of paraffins. This information has not been reviewed or verified by ECHA, and may change without prior notice. Paraffins are also called alkanes and have the general formula of CnH2n+2, where n is the number of carbon atoms in a given molecule. Corrections? Information on applicable regulatory frameworks is also automatically generated and may not be complete or up to date.
