Figure 4. The concentration-response relationship of 16 PCP chemical ingredients at 12 h (•: 12 h experimental value; -: the fitted CRC; ---: 95%OCI). Data for BET, E4C, ODO, and POE were sourced from our previous study^[27]. PCP: Personal care products; CRC: concentration-response curve; OCI: observed confidence interval; BET: betaine; ODO: 1,2-octanediol; POE: 2-phenoxyethanol.
