Table 3. Median [Range] of Concentrations (μg/g) of Phthalate and Organophosphate (OP) Plasticizers Detected above 100 μg/g in at Least One Sample for 40 Nail Polish Samples by Generation of Label and Detection of TPHP^a.

		median [range]
plasticizer	type	old generation label (n = 12)	new generation label (n = 28)	detected TPHP (n = 24)	no detected TPHP (n = 16)
DEHP	phthalate	1.61 [0.703, 2.23]	1.67 [<0.001, 331]	1.51 [<0.001, 2.50]	68.5 [0.684, 331]b
PBDPP	OP	0.287 [<0.005, 0.62]	0.522 [<0.005, 115]	0.531 [<0.005, 2.27]	0.151 [<0.005, 115]
TPHP	OP	3730 [<0.002, 7940]	<0.002 [<0.002, 5330]c

^aNote: Old generation, unlabeled or 3-Free; New generation, 5- to 13-Free; < , calculated value fell below the limit of detection.

^bSamples with detected TPHP significantly different from samples without detected TPHP at p < 0.05 (Wilcoxon rank sum test).

^cNew generation samples significantly different from old generation samples at p < 0.001 (Wilcoxon rank sum test).
