,The Cosmetic Ingredient Review (CIR) Expert Panel conducted a comprehensive safety evaluation of several phthalates used in cosmetic and personal care products. Phthalates, including dibutyl phthalate (DBP), diethyl phthalate (DEP), and dimethyl phthalate (DMP), function primarily as plasticizers, solvents, and fragrance fixatives in products such as nail polish, hair sprays, and skin-care formulations. The assessment reviewed toxicological data, animal studies, human exposure information, reproductive and developmental toxicity findings, and available epidemiological research. While certain phthalates have demonstrated endocrine or reproductive effects at high doses in laboratory studies, the Panel emphasized that exposure levels from cosmetic use are significantly lower than those associated with adverse outcomes. Dermal absorption rates, frequency of use, and concentration limits were carefully evaluated to determine consumer safety margins. CIR concluded that DBP, DEP, and DMP are safe for use in cosmetics under current conditions of use and concentration. The report also noted regulatory restrictions in some regions and encouraged ongoing monitoring of scientific developments to ensure continued consumer protection. Overall, the findings support that typical cosmetic exposure does not pose significant health risks.
