This study was conducted to determine 10 preservatives (benzyl alcohol (BAl), phenoxyethanol (PE), benzoic acid (BA), sorbic acid (SA), methyl paraben (MP), ethyl paraben (EP), propyl paraben (PP), isopropyl paraben (IPP), butyl paraben (BP), isobutyl paraben (IBP)) levels in 125 cosmetics (n = 125) for children by the simultaneous analysis of HPLC. The detection ranges were as follows; 0.01 ~ 0.91% (n = 35) for PE, 0.01 ~ 0.48% (n = 28) for BA, 0.01 ~ 0.78% (n = 9) for BAl, 0.01 ~ 0.11% (n = 3) for SA, 0.04 ~ 0.21% (n = 8) for MP, 0.02 ~ 0.09% (n = 8) for PP, and 0.04% (n = 1) for EP. The order of detection rates was cleanser (63%) > cream (48%) > sunscreen (46%) > lotion (38%) > oil (13%). At least one of target preservatives was contained in 50% (63/125) of samples and the content of the detected preservatives was within maximum allowed amount established by KFDA. Phenoxyethanol and benzoic acid were used more frequently than paraoxybenzoate esters (parabens) in cosmetics for children and the detected parabens was mainly the mixture of methyl paraben and propyl paraben.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
