RESORCINOL is LEAST likely to be in a POISON OAK (urushiol-containing) preparation, whose allergen is a catechol used in hyposensitisation products. Resorcinol and its derivatives are found in ACNE peeling preparations and keratolytics, in HAIR DYES, and in fragrances and plant extracts - it cross-reacts with hydroquinone, hexylresorcinol and other phenols, so patch testing and label scrutiny are needed.
