This substance is used in the following products: laboratory chemicals, lubricants and greases and metal working fluids. Please note: Precautionary measures and guidance on safe use concern the use and handling of the specific substance as such, not of the presence of the substance in other articles or mixtures. Normal paraffins (n -paraffins or n -alkanes) … The precautionary measures and guidance on safe use are as submitted to ECHA by registrants under the REACH Regulation. 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. Figure 1.10 shows the statistically possible number of isomers of paraffins that increase exponentially with carbon number, starting with just one isomer for butane, reaching approximately 60,000 for C18 paraffins. PARAFFIN VISCID, EXTRA PURE, DAB, PH. This information has not been reviewed or verified by ECHA, and may change without prior notice. The site editor may also be contacted with questions or comments about this Open Educational Resource. Paraffin wax was identified by Carl Reichenbach in 1830.[1]. When information is available in all sources, the first two are displayed as a priority. The REACH registered substance data and the C&L Inventory portal will be upgraded from the 9th November. If available, additional information on classification and labelling (C&L) is derived from REACH registration dossiers submitted by industry. *Please select more than one item to compare 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. All these atoms are linked to each other via single covalent bonds. Please send comments or suggestions on accessibility to the site editor. Other release to the environment of this substance is likely to occur from: indoor use as processing aid, outdoor use as processing aid, indoor use in close systems with minimal release (e.g. Cycloalkanes (naphthenes) and the effect of cyclic structures on the physical properties of alkanes. This section provides links to the list of precautions (precautionary statements) and to the guidance on safe use, if they have been provided in REACH registration dossiers. 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.

REACH registration dossiers have greater data requirements (such as supporting studies) than do notifications under CLP.

Substances for which classification and labelling data have been notified to ECHA by manufacturers or importers. Paraffin hydrocarbon, also called alkane, any of the saturated hydrocarbons having the general formula C n H 2n+2, C being a carbon atom, H a hydrogen atom, and n an integer. For example, the open formula for n-butane, n-C4, can be shown as CH3-CH2-CH2-CH3, based on the quadrivalency of the carbon atom, and for simplicity, only the carbon-carbon bonds are drawn and most C-H bonds are omitted, as shown in Figure 1.7 and 1.8 on the previous page. The per substance REACH registration status will be made available as soon as possible thereafter. Harmonised classification and labelling is a legally binding classification and labelling for a substance, agreed at European Community level. Furthermore, some substances can be found in an article, but with unlikely exposure (e.g. What part of the liturgical calendar are flowers removed from the sanctuary? Release to the environment of this substance can occur from industrial use: formulation of mixtures, in processing aids at industrial sites, manufacturing of the substance, formulation in materials, in the production of articles, as an intermediate step in further manufacturing of another substance (use of intermediates), as processing aid, for thermoplastic manufacture, as processing aid and of substances in closed systems with minimal release. What is the chemical formula for Paraffin. The Chemical Formula for Paraffin is CnH2n+2. It is possible that a harmonisation is introduced through an amendment to the CLP Regulation. Note in Figure 1.10 that the removal of an H atom from alkanes generates free radicals (reactive species containing unpaired electrons) that are called alkyl species (e.g., methyl formed from methane and ethyl formed from ethane by removing a hydrogen atom) also a radical with an unpaired electron. Paraffins are alkanes, which are saturated hydrocarbons having the chemical formula C n H 2n +2 (where n is a whole number). The ‘Substance identity’ section is calculated from substance identification information from all ECHA databases. This section is based on three sources for information (harmonised classification and labelling (CLH), REACH registrations and CLP notifications). In chemistry, paraffin is the common name for the alkane hydrocarbons with the general formula CnH2n+2. This information is only displayed if the substance is well-defined, its identity is not claimed confidential and there is sufficient information available in ECHA’s databases for ECHA’s algorithms to generate a molecular structure. Who is the longest reigning WWE Champion of all time? The source of the information is mentioned in the introductory sentence of the hazard statements. disinfectants, pest control products), finger paints, perfumes and fragrances, polishes and waxes and cosmetics and personal care products. Figure 1.10. Figure 1.9. These notifications can be provided by manufacturers, importers and downstream users. Information on applicable regulatory frameworks is also automatically generated and may not be complete or up to date. Corrections?

The information is aggregated from the data coming from REACH substance registrations provided by industry. This substance is used in the following products: lubricants and greases and laboratory chemicals. The CLP Regulation makes sure that the hazards presented by chemicals are clearly communicated to workers and consumers in the European Union. In that case, the ATP (Adaptation to Technical Progress) number is displayed. The crystallization/fusion of their molecular chain involves a large amount of latent heat. This substance is used by consumers, by professional workers (widespread uses), in formulation or re-packing, at industrial sites and in manufacturing. cooling liquids in refrigerators, oil-based electric heaters) and outdoor use in close systems with minimal release (e.g. The simplest alkane is methane (CH 4), which is also represented as C 1. Likewise the per substance indication of harmonised C&L, Seveso directive, or notified C&L regulatory context will be made available as soon as possible.
