Conclusion
A gas comparison stereopycnometer was used for the determination of the density and relative density of Ethyl Ascorbic acid.
The density of the test item at 20°C was 1.47 g/cm3(1.47E+03 kg/m3).
The relative density was 1.47.
Applicant's summary and conclusion
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.
