Applicant's summary and conclusion
- Conclusions:
- An absolute density of 1.20 g/mL was observed for aryloxyacrylate at room temperature (22-25 °C).
- Executive summary:
A pycnometer method was used for the determination of the absolute density of acryloxyacrylate. The material was melted, repeatedly loaded to a stainless steel pycnometer, and allowed to soldify until the pycnometer was completely filled to obtain absolute density of a solid material. The method performed was comparable to guideline but not GLP compliant; therefore the study is considered reliable with restrictions.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
