The patients sensitised to sunscreen agents who attended our Contact Dermatitis Clinic between February 1985 to March 1987 have been reviewed. 15 (5%) of 280 patients tested with sunscreens had positive reactions; 3 of them were allergic to more than one agent. The most frequent contact allergens were hydroxy methoxy methyl benzophenone (Mexenone) [6], followed by isopropyl dibenzoylmethane (Eusolex 8020/8021) [5], octyl dimethyl para-aminobenzoate (Escalol 507) [2], and one reaction each to butyl methoxy dibenzoylmethane (Parsol 1789), amyl dimethyl para-aminobenzoate (Escalol 506), and ethoxy ethyl-p-methoxy cinnamate (Givtan F). Positive photopatch tests were seen with isopropyl dibenzoylmethane, butyl methoxy dibenzoylmethane, para-aminobenzoate (PABA) and ethoxy ethyl-p-methoxy cinnamate, one reaction each.

Background: Despite the enormous increase in sunscreen use, allergic contact (AC) and photoallergic (PA) reactions to ultraviolet (UV) filters are considered rare.
Objectives: To analyse the data from 2715 patients who underwent photopatch testing at St John's Institute of Dermatology during the period 1983-98.
Methods: A retrospective analysis of all positive photopatch test episodes was undertaken with the results retrieved from the environmental dermatology database and further verified with the original archived patch test documentation for each individual patient.

A method for quantitative determination of eleven sunscreen agents (benzophenone-4,p-amino-benzoic acid, salicylic acid, benzophenone-3,phenyl salicylate, 4-methylbenzylidene camphor, octyl dimethyl p-amino-benzoate, isopropyl dibenzoylmethane, butyl methoxydibenzoylmethane, octyl methoxycinnamate, octyl salicylate) in cosmetic products is described. It was based on a high performance liquid chromatographic separation under the condition of isocratic elution with a mixture solution of methanol-THF-water-70% perchloric acid (200:200:160:0.1) by using a column packed with 10 microns YWG-C15 and UV detection.

The incidence of skin cancer is increasing rapidly and sunscreens have been recommended in order to reduce damage from sunlight. In this investigation we have studied the change in the absorption spectrum of some photoactive organic species in sunscreens after ultraviolet A and ultraviolet B irradiation in a dose normally encountered during a full day in the sun. Samples of a number of photoactive compounds commonly used in sunscreens were irradiated with ultraviolet A and ultraviolet B light.

The purpose of this study was to evaluate the prevalence of sunscreen contact allergy and/or contact photoallergy in 370 patients with suspected photodermatitis. Patch and photopatch tests were performed using the French Society of Photodermatology (SFPD) standard series. A total of 57 cases of contact allergy and/or photocontact allergy to sunscreens were diagnosed (15.

Since 1990 7 sunscreen allergens have been included in the standard photopatch protocol at 2 Swedish dermatology clinics. 355 consecutive patients with suspected photosensitivity were tested, and in 28 of these (7.9%), a total of 42 allergic reactions were found.
