“Closest Acid Yellow 3/D&C Yellow No.10 evidence: purified D&C Yellow No.10 itself did not sensitize guinea pigs, while contaminating quinophthalone was implicated in skin sensitization risk.”
“Closest Acid Yellow 3/D&C Yellow No.10 evidence: modified Draize testing evaluated skin sensitization risk in combination dye systems, supporting use as a colorant rather than an active skin-benefit ingredient.”
“Closest quinoline-yellow cosmetic-dye evidence: in vitro testing raised genotoxicity concerns if absorbed/metabolized through skin, so it does not substantiate skin benefits beyond coloration.”
“Closest synthetic-colorant review evidence: Quinoline Yellow is discussed mainly for toxicological and regulatory safety, not for functional skin benefits.”
