Identification and estimation of phthalate esters in the commonly used deodorants in UAE by using HPTLC method

ABSTRACT

The study aims to identify and estimate four phthalate esters viz., Dibutyl phthalate [DBP], Diethyl phthalate [DEP], Di [2-ethylhexyl] phthalate [DEHP], Dimehtyl phthalate [DMP] in commonly used deodorants by using High performance Thin Layer Chromatography [HPTLC]. 10 brands of most commonly used deodorants; the volume and frequency of their use were selected based on a questionnaire based survey in UAE. DBP, DEP, DEHP, and DMP were identified in deodorants by comparing the R[f] value with their respective standards by using HPTLC. The estimated phthalate contents were extrapolated to calculate the hazard indices. The results showed that these 4 different phthalates were present in various brands of deodorants. DBP was found to be present in highest concentrations in most of the deodorants. The hazard indices of all four phthalates were found to be less than 1. In our study, the different phthalates [DBP, DEP, DEHP and DMP] contents in 10 brands of commonly used deodorants in UAE were identified and estimated. The Hazard Indices for phthalates estimated [DBP, DEP, DEHP and DMP] in different brands of commonly used deodorants in UAE were found to be below 1 indicates the safety of these products for human use
