Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
Tin monooxide (SnO) is insoluble in water (< 0.0002 mg/L) at neutral pH. It remains solid up to > 550°C and has a high relative density.
Generally, absorption of tin from the gastrointestinal tract is low in humans and laboratory animals, including rats, mice, rabbits, cats, and dogs. This information has been derived from soluble tin compounds. Tin monoxide is insoluble in water (< 0.2 microgramms/L), but dissolves in acids to form Sn2+ and in base to form stannite ion, Sn(OH)3–.
Therefore, it is not expected to be absorbed after skin contact. Absorption from the gastrointestinal tract is expected to be very low.
Key value for chemical safety assessment
Additional information
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.
