Artificial nails are an essential component of nail cosmetics. The artificial nails are either preformed and glued onto the existing nail plate or they are custom made by applying a polymerizing mixture to the existing nail plate and overlying the template with a paintbrush that is subsequently allowed to harden into an acrylic nail. Artificial nails require regular maintenance. Read More

Phthalates are a large group of chemicals used in many everyday consumer products such as food packaging, household cleaners, cosmetics, fragrances and personal care products (PCPs). A number of diseases such as obesity, hypertension, as well as reproductive system effects and endocrine disorders have been linked to phthalate exposure through the use of PCPs, due to their frequent use and high phthalate content. In this study we review available literature on phthalates and their metabolites in urine and report the various determinants of exposure through the use of PCPs in infants, toddlers, children and adults.
