Parabens are compounds often added to cosmetics and pharmaceutics as preservatives for fungi and bacterial growth, but, recent studies have linked these compounds to several adverse side-effects such as cancer, miscarriage and infertility. The extraction of methyl paraben from (hand cream, body lotion, blusher, body cream, and bath foam) was studied using liquid-liquid extraction with ethyl acetate as a solvent, and double beam UV-spectrophotometer at wave length 282 nm. Calibrations are linear (correlation coefficient r>0.997) and the limit of detection was 2.358 μg/mL The concentrations of methyl paraben for the selected cosmetic samples were ranged from 0.077% to 0.451%.
