Liquid chromatographic separation and fluorometric determination of cis- and trans-isoeugenol in perfumes, colognes, and toilet waters.

A liquid chromatographic (LC)-fluorometric method is described for the determination of cis- and trans-isoeugenol (2-methoxy-4-propenylphenol) in perfumes, colognes, and toilet waters. A test portion of the product is added to diethyl ether, and the isoeugenol isomers are extracted with sodium hydroxide solution. The basic extract is then acidified, and the isoeugenol isomers are extracted with isooctane. Aliquots of the isooctane extract are analyzed by using a silver ion cation exchange LC column interfaced to a spectrophotofluorometer. Each isomer in the product is determined by comparing its fluorescence emission intensity with that of an external standard consisting of a mixture of both isomers in which the relative concentration of each has been determined. Average recoveries from various commercial fragrances fortified with a mixture of cis- and trans-isoeugenol with total isoeugenol content of 0.1, 0.5, and 4.0 mg/mL ranged from 87 to 105% for the trans-isomer (SD = 4.6%) and from 83 to 113% for the cis-isomer (SD = 6.7%). The limit of determination is approximately 0.002 mg/mL.

Determination of cinnamyl anthranilate in perfume, cologne, and toilet water by liquid chromatography with fluorescence detection.

A liquid chromatographic method with fluorescence detection was developed for the determination of cinnamyl anthranilate in perfumes and other fragrance compositions. The method was evaluated by conducting recovery studies of 10 different commercial fragrance compositions to which cinnamyl anthranilate had been added at levels of 0.1, 0.5, and 1.0 mg/mL. Recoveries ranged from 91 to 103% with a mean of 97% and a standard deviation of +/- 3.3%.

[Contact allergy for perfume ingredients in cosmetics and toilet articles].

Fragrance materials are not only present in products primarily used for their scent such as perfume, eau de toilette, deodorant and aftershave, but also in cosmetics, toiletries, household products and industrial materials. Of the general population, approximately one percent are allergic to fragrance materials, men nearly as frequent as women. Of patients consulting the dermatologist because of dermatitis, 6-11% have a positive patch test to the fragrance mix. Allergic contact dermatitis due to fragrances usually consists of erythema and desquamation, often localized in the neck, behind the ears, in the arm-pits or around the eyes. It can worsen pre-existing dermatoses such as hand eczema, atopic dermatitis, perianal dermatitis or vulvar dermatitis. The diagnosis of contact allergy to fragrances is made by epicutaneous tests with the European standard series (including some markers for fragrance sensitivity: the fragrance mix, balsam of Peru and colophony) and the patient's own contact materials. A positive patch test reaction must be followed by evaluation of its relevance. Advice to the patient is directed towards avoidance of fragranced products, if possible, and explanation of how use tests can identify fragranced products which can be used without ill effects.
