Tin (II) oxide: Does not have an individual approval but may be used under an appropriate group standard

Though tin metal is very poorly absorbed, tin compounds may be absorbed via oral, inhalation, or dermal routes, with organotin compounds being much more readily absorbed than inorganic tin compounds. Tin may enter the bloodstream and bind to hemoglobin, where it is distributed and accumulates mainly in the kidney, liver, lung, and bone. Tin and its metabolites are excreted mainly in the urine and feces. (L308)

Tin oxides are used in solders, protective coatings, and alloys; [ACGIH] Used as a reducing agent and to make stannous salts; [Merck Index] Used to make gold-tin and copper-tin ruby glass; [INCHEM CICADS]

Tin(II) oxide is used as a precursor in manufacturing of other, typically divalent, tin compounds or salts, and as a reducing agent and in the creation of ruby glass. (L321)
