EC number: 273-271-8 | CAS number: 68955-35-1 A complex combination of hydrocarbons produced by the distillation of products from a catalytic reforming process. It consists of hydrocarbons having carbon numbers predominantly in the range of C4 through C12 and boiling in the range of approximately 30°C to 220°C (90°F to 430°F). It contains a relatively large proportion of aromatic and branched chain hydrocarbons. This stream may contain 10 vol. % or more benzene.

Description of key information
Single values for the category or individual UVCB members are not applicable The auto flammability range for substances included in this category is 280 to 470°C.
Key value for chemical safety assessment
Additional information
The auto flammability range for substances that comprise the Low Boiling Point Naphthas (Gasolines) category is 280 to 470°C (Eaton 1990).The CONCAWE (2010) “Compilation of selected physico-chemical properties of petroleum substances” report also reports auto flammability for the gasoline naphtha category to be >200°C. Additionally, TOTAL (1979) reported self-ignition temperature of commercial gasoline to be 495°C (Commercial gasoline 100LL); 445°C (Commercial gasoline; low NOM); and 435°C (commercial gasoline; high NOM). Due to the highly flammable nature of gasoline naphthas, this measurement if considered irrelevant. It is also not possible to define a single self-ignition temperature for a UVCB substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
