She was patch tested to our face series, flavours series, bakery series, her own toothpaste, her own nail varnish, her own lip products, and the standard series including fragrance mix II. She had positive reactions to fragrance mix (þ), fragrance mix II (þþ), tosylamide formaldehyde resin (þþ), cinnamaldehyde (þ), oil of lemongrass (2% pet.) (þþ) and her own nail varnish (þþ) and ‘petroleum’ (þ). She subsequently had a positive reaction (þþ) to citral (2% pet.) in the breakdown of fragrance mix II. Although the patient had reported applying ‘petroleum’ (normally yellow soft paraffin) to her lips, when the product was examined it was found to be Vaseline lip balm with aloe vera. Of note, citral is listed as an ingredient on the packaging. Changing to plain Vaseline and avoidance of perfume and nail varnish resulted in symptomatic improvement.
