Abstract

Phthalates, endocrine disrupting chemicals, are similar in structure to sex hormones and mainly show reproductive toxicity and developmental toxicity. In this study, we analyzed 11 phthalates, including 3 kinds of phthalates prohibited in cosmetic use and 8 kinds of phthalates regulated in ¡®Common standards for children¡¯s products safety¡¯ and EU cosmetic regulation (EC No. 1223/2009). The phthalate analysis was optimized using GC-MS/MS. In analytical method validation, this method was satisfied in specificity, linearity, recovery rate, accuracy and MQL. Therefore, we used this method to analyze 82 products of Nail cosmetics & polish. Although six phthalates such as DBP, BBP, DEHP, DPP, DIBP and DIDP were detected at concentrations of 1.0 ¡ 59.8 §¶/g, they were suitable to Korean cosmetic standards. DIBP and DBP were detected at concentration of 1.1 ¡ 2.6 §¶/g in artificial nail, DBP and DEHP were 1.4 ¡ 2.5 §¶/g in glue for nails, and DIBP, DBP, and DEHP were 2.5 ¡ 33.3 §¶/g in nail stickers. Although substances such as DBP and DEHP in artificial nail, Glue for nails, and nail stickers were detected, they were suitable to ¡®Common safety standards for children¡¯s products. DIBP is not a regulated substance in Korea but showed the third highest detection rate following DBP (84.6%) and DEHP (63.4%). The concentration of phthalates detected in nail products is considered to be safe in current standards but continuous monitoring and research about non-regulated substances are also needed to be considered.
