A complex combination of hydrocarbons obtained from the fractionation stabilization of straight-run naphtha, distillation tail gas and catalytic reformed naphtha stabilizer tail gas. It consists of hydrocarbons having carbon numbers in the range of C3 through C6, predominantly butane and isobutane.
The ‘Substance identity’ section is calculated from substance identification information from all ECHA databases. The substance identifiers displayed in the InfoCard are the best available substance name, EC number, CAS number and/or the molecular and structural formulas.
Some substance identifiers may have been claimed confidential, or may not have been provided, and therefore not be displayed.
The EC Number is the numerical identifier for substances in the EC Inventory. The EC Inventory is a combination of three independent European lists of substances from the previous EU chemicals regulatory frameworks (EINECS, ELINCS and the NLP-list). More information about the EC Inventory can be found here.
If the substance was not covered by the EC Inventory, ECHA attributes a list number in the same format, starting with the numbers 6, 7, 8 or 9.
The EC or list number is the primary substance identifier used by ECHA.
The CAS number is the substance numerical identifier assigned by the Chemical Abstracts Service, a division of the American Chemical Society, to substances registered in the CAS registry database. A substance identified primarily by an EC or list number may be linked with more than one CAS number, or with CAS numbers that have been deleted. More information about CAS and the CAS registry can be found here.
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. 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.
The molecular structure is based on structures generated from information available in ECHA’s databases. If generated, an InChI string will also be generated and made available for searching. 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.

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. The CLP Regulation makes sure that the hazards presented by chemicals are clearly communicated to workers and consumers in the European Union. The CLP Regulation uses the UN Global Harmonised System (GHS) and European Union Specific Hazard Statements (EUH).
This section is based on three sources for information (harmonised classification and labelling (CLH), REACH registrations and CLP notifications). The source of the information is mentioned in the introductory sentence of the hazard statements. When information is available in all sources, the first two are displayed as a priority.
The purpose of the information provided under this section is to highlight the substance hazardousness in a readable format. 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. in case of consumer and professional uses). Other relevant information includes the following:
To see the full list of notified classifications and to get more information on impurities and additives relevant to classification please consult the C&L Inventory.
More information about Classification and Labelling is available in the Regulations section of ECHA website.
Harmonised classification and labelling is a legally binding classification and labelling for a substance, agreed at European Community level. Harmonisation is based on the substance’s physical, toxicological and eco-toxicological hazard assessment.
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.
If the substance is covered by more than one CLH entry (e.g. disodium tetraborate EC no. 215–540–4, is covered by three harmonisations: 005–011–00–4; 005–011–01–1 and 005–011–02–9), CLH information cannot be displayed in the InfoCard as the difference between the CLH classifications requires manual interpretation or verification. If a substance is classified under multiple CLH entries, a link to the C&L Inventory is provided to allow users to view CLH information associated with the substance and no text is automatically generated for the InfoCard.
It is possible that a harmonisation is introduced through an amendment to the CLP Regulation. In that case, the ATP (Adaptation to Technical Progress) number is displayed.
More info on CLH can be found here.
If available, additional information on classification and labelling (C&L) is derived from REACH registration dossiers submitted by industry. This information has not been reviewed or verified by ECHA, and may change without prior notice. REACH registration dossiers have greater data requirements (such as supporting studies) than do notifications under CLP.
If no EU harmonised classification and labelling exists and the substance was not registered under REACH, information derived from classification and labelling (C&L) notifications to ECHA under CLP Regulation is displayed under this section. These notifications can be provided by manufacturers, importers and downstream users. ECHA maintains the C&L Inventory, but does not review or verify the accuracy of the information.
Note that for readability purposes, only the pictograms, signal words and hazard statements referred in more than 5% of the notifications under CLP are displayed.

The ‘Properties of concern’ section shows ECHA-assigned graphical indicators for certain substance properties that are regarded as being of relevance or importance to human health and/or the environment based on the information provided to the Agency.
Properties of concern are calculated at four "levels" of certainty:
The following properties of concern are calculated:
The substance properties displayed in this section are derived from Harmonised classification and labelling (CLH) data, entries in the Candidate list of substances of very high concern for authorisation, the PBT assessment list, the ED assessment list, REACH registered dossier data and from notifications made under CLP. A prioritisation hierarchy means that data is taken from harmonised C&L data and regulatory lists first, then REACH registrations and finally from CLP notifications. By clicking on the "More details" button you can see the exact origin(s) of each Property of Concern.
Impurities or additives: When a specific critical property is calculated from industry data and where the majority of data submitters have indicated that the property relates to cases containing impurities and/or additives, then the respective critical property icon is modified with an asterisk (*).
The InfoCard summarises the non-confidential data of a substance held in the databases of the European Chemicals Agency (ECHA). InfoCards are generated automatically based on the data available at the time of generation.
The quality and correctness of the information submitted to ECHA remains the responsibility of the data submitter. The type of uses and classifications may vary between different submissions to ECHA and for a full understanding it is recommended to consult the source data. Information on applicable regulatory frameworks is also automatically generated and may not be complete or up to date. It is the responsibility of the substance manufacturers and importers to consult official publications, e.g. the electronic edition of the Official Journal of the European Union.
InfoCards are updated when new information is available. The date of the last update corresponds to the publication date of the InfoCard and not necessarily to the date in which the update occurred in the source data.
Here you can find all of the regulations and regulatory lists in which this substance appears, according to the data available to ECHA. This substance has been found in the following regulatory activities (directly, or inheriting the regulatory context of a parent substance):
