Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

EC number: 295-459-9 | CAS number: 92045-77-7 A complex combination of hydrocarbons obtained as a semi-solid from dewaxed paraffinic residual oil treated with hydrogen in the presence of a catalyst. It consists predominantly of saturated microcrystalline and liquid hydrocarbons having carbon numbers predominantly greater than C20.

Description of key information
Additional information
Key study data are available for relevant physicochemical endpoints for petrolatum. All substances in the category are semi-solids (CONCAWE, 2009) at ambient temperature (20°C) and pressure (101.3 kPa). There is no guideline method available for this endpoint and data presented are based on visual observation, supported by data on melting point and viscosity. The melting point for chemicals in this category ranges from 36 to 71°C (CONCAWE, 2010a; Warth, 1956; and CONCAWE, 1999a). Boiling points for members of this category are generally ≥300°C (CONCAWE, 2010a; EWF, 1990) and density ranges from 0.77 to 0.96 g/cm3 at 15°C (CONCAWE, 2010a; EWF, 1990).
Flash points for members of this category are generally >160°C (CONCAWE, 2010a; EWF, 1990). The viscosity of substances in this category ranges from 3 to 30 mm2/s at 100°C (CONCAWE, 1999a).
Petrolatums do not meet EU CLP classification criteria (EC No. 1272/2008) for flammability, explosivity,oxidising properties or aspiration hazard.
Based on information available on the properties of the substances that comprise the petrolatum category of chemicals, specific data are not presented for the following endpoints: vapour pressure, partition co-efficient, water solubility, granulometry, surface tension, stability in organic solvents, flammability, auto flammability, explosiveness, and dissociation constant. Appropriate waiving statements are provided to indicate why data for these REACH endpoints are not applicable. The physico-chemical data presented are considered representative for the substances included in the category Petrolatum.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
