Safety Assessment of Tin(IV) Oxide as Used in Cosmetics

The authors noted that the results of this study corroborate the conclusion that tin(IV) oxide fume, and not tin(IV) oxide dust, is more likely to be the cause of stannosis.28 Stannosis is the form of pneumoconiosis (non-fibrotic form) that results from the inhalation of tin in the form of tin(IV) oxide fumes or dust.

Biological interactions in vitro of zinc oxide

Due to their small size, extensive surface area and surface characteristics, nanomaterials possess considerable potential to interact with the biological system when in contact with the body. Such interactions, on one hand may be beneficial if controlled appropriately, but on the other hand, may lead to objectionable side-effects.

Pharmacokinetic and Toxicological Evaluation of a Zinc

Sclerosing agents as zinc gluconate-based chemical sterilants (Infertile) are used for chemical castration. This solution is injected into the animal testis, but there are not enough evidences of its safety profiles for the receivers. The present work aimed to establish the pharmacokinetics and toxicological activity of Infertile, using in vitro and in silico approaches.
