Can alumina cause aluminum toxicity in humans when used in cosmetics?

Alumina is aluminium oxide with chemical formula Al2O3. When it is applied on skin as cosmetics, Aluminium from it will get absorbed in to the blood. However, amount absorbed will be less (< 1%), but small amount of aluminium in blood can have significant toxic effects. 0.1 mg/kg/d is tolerable daily intake (TDI) for aluminium given by Europen Food Safety Authority (EFSA). Conclusively, Alumina can cause aluminium toxicity when used above particular limit (Roughly saying, >10% in your body lotion or body powder product. Limit will be even less for baby products)
