To the Editor.—
There have been no previous reports of allergic contact sensitivity to imidazolidinyl urea (Germall 115), which is a preservative that has found increasing popularity in the cosmetic industry.1 This is the report of a patient who had an acute contact dermatitis following the use of a popular moisturizing lotion containing Germall 115.
Report of a Case.—
A 49-year-old white woman had an acute eczematous dermatitis of the face of one week's duration. Her symptoms began two weeks after the daily use of an allergy-tested moisturizing lotion concentrate. The condition cleared up during a one-week period of therapy with a fluorinated steroid solution applied three times daily and abstinence from all cosmetics. Patch tests one week later to routine allergens, and a cosmetic kit (supplied by Texas Pharmacal Company, San Antonio) were negative except for a 2+ reaction to the offending moisturizer and to a hypoallergenic liquid
