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.
