TANTALUM ETHOXIDE/ISOPROPOXIDE.

Avoid / SKIN PROTECTING

Tantalum Ethoxide/Isopropoxide are highly reactive metalorganic compounds that readily hydrolyze upon contact with water or skin moisture, generating tantalum oxide and alcohols. While the resulting tantalum oxide nanoparticles have shown *in vitro* antioxidant activity, there is no direct evidence of this ingredient's cosmetic efficacy on skin, and it is known to cause significant irritation.

Summary

Science

Mechanism of Action

Upon contact with skin moisture or water, Tantalum Ethoxide/Isopropoxide rapidly undergo hydrolysis, transforming into tantalum oxide (Ta2O5) and liberating either ethanol or isopropanol. There is no established direct mechanism by which these compounds, prior to decomposition, provide cosmetic benefits to the skin.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk High

Tantalum Ethoxide/Isopropoxide are classified as hazardous, irritant, and corrosive materials in industrial safety data sheets. They induce skin irritation, potential contact dermatitis, and severe eye irritation, primarily due to their rapid hydrolysis and subsequent release of irritating alcohols like ethanol or isopropanol. The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically evaluated these compounds, highlighting a significant lack of cosmetic safety data for such metal alkoxides.
