Fluorometric Determination of Formaldehyde in Cosmetic Products
Clifton H. Wilson

Synopsis

To overcome interference by perfume ingredients, a method has been developed for determining FORMALDEHYDE in COSMETICS by forming a FLUORESCENT LUTIDINE DERIVATIVE and measuring the fluorescence on a SPECTROPHOTOFLUOROMETER. Satisfactory recoveries were obtained from samples of shampoos, bath oils, hair cosmetics, lotions, and creams to which formaldehyde had been added. Formaldehyde was also determined in commercial samples of nail hardener, bubble bath, hair rinse, and shampoos. Of seven other aldehydes examined, only an aryl sulfonamide-formaldehyde resin gave a false positive test.
