Glyceryl p-aminobenzoate patch testing in benzocaine-sensitive subjects.
Benzocaine-reactive patients were patch tested to two commercial sources of glyceryl p-aminobenzoate containing varying concentrations of benzocaine as a contaminant. Eleven of 20 reacted to the source with approximately 0.3% benzocaine; none reacted to the source with approximately 0.001% benzocaine.
