Determination of Aluminum Concentration in Deodorant Samples

الملخص

This study aimed to estimate aluminum levels in seven antiperspirant samples collected from various sources in the local markets of Al-Bayda city, Libya. Aluminum concentration was determined using an Atomic Absorption Spectrometer. The results indicated that the aluminum concentration range in the samples was between 0.108 and 0.289 parts per million (ppm), and the percentage of aluminum in these samples ranged from 21% to 57%. These data suggest that six samples exceeded the permissible limit set by the U.S. Food and Drug Administration (FDA) for over-the-counter products. The FDA allows aluminum percentages between 1% and 25% in antiperspirants without a prescription, and between 25% and 40% with a prescription.
