This study aimed to determine lead and cadmium concentration in commercial cosmetic soaps from Ciamis. Sample preparation was carried out with the wet destruction using HN03 : 1-1202 (3: l). Lead and cadmium were analyzed using Atomic Absorption Spectrophotometer (AAS) at the specific wavelength respectively 283,3 nm and 228.8 nm. The results showed, just one sample that contain exceed lev Is of lead and cadmium, and 9 samples are meet the requirements.
