Alumina, or Allumina, or "aluminum oxide" used in cosmetics is essentially the same as that used in medical devices.
The Food and Drug Administration (FDA) evaluated the safe use of alumina in various medical devices and aluminum hydroxide in over-the-counter drugs, which included a review of data on human and animal safety. The Cosmetic Ingredient Review (CIR) expert group has reviewed FDA assessments as part of the basis for determining the safety of these ingredients as used in cosmetics. The Panel concluded that alumina and aluminum hydroxide are safe in current usage practices with the concentration described in this safety assessment (1).
Alumina is used for the removal of chromium from tannery wastewater (2) and as an absorbent of methylene blue from water (3).
In hip disease THA may be a reliable treatment option in Legg-Calve-Perthes disease (4).
Most enzymes are extremely sensitive to UV light in all its ranges and their activity can irreversibly decay even after a short exposure time. After trapping within the sol-gel of matrices treated with alumina, all the enzymes examined have shown a better UV stabilization (5).
