A hydrocortisone preparation containing methylparaben and propylparaben provoked bronchospasm and pruritus when given intravenously to an asthmatic patient, whereas another hydrocortisone preparation without paraben preservative did not. Direct and passive transfer (Prausnitz-Küstner) skin tests for immediate hypersensitivity to parabens were positive.

Abstract Background. To test the reliability and reproducibility of the patch test with a paraben mix, we added a second paraben mix allergen to our standard tray and compared the results achieved with these two allergens. Methods. Two hundred and fifteen consecutive patients, undergoing patch testing with a standard series, were simultaneously tested ...

A high performance liquid chromatographic technique has been used to determine phenoxetol, methyl paraben, ethyl paraben, n-propyl paraben, iso-butyl paraben, n-butyl paraben and croconazole.HCl. The method developed involves isocratic, reversed phase chromatography. The range of quantitation was found to be 90-135.0 micrograms ml-1 for phenoxetol, 2.0-

Four cases of allergic contact sensitivity to alkyl esters ofp-hydroxybenzoic acid (parabens) were detected during routine closed patch tests on 91 patients with contact dermatitis. All four patients had refractory dermatitis of unknown cause and all were using topical medications containing parabens as preservative.

Topical Parabens: Benefits and Risks
Dermatology, 1977Parabens are the most frequently used preservative in dermatological medications. Some allergies have been reported to parabens, but these risks must be considered with respect to the benefits of parabens in concentrations used as preservatives in dermatological formulations.

Paraben esters are incorporated in most dermatologic and cosmetic creams and lotions as preservatives. A two-year clinical study on the allergenic potential of these bacteriostatic and fungistatic chemicals showed that of 273 consecutive patients with chronic dermatitis who were routinely patch tested to 5% paraben in petrolatum had paraben allergy, an

Parabens (p-hydroxybenzoate esters) are a group of widely used preservatives in topically applied cosmetic and pharmaceutical products. Parabens display weak associations with the estrogen receptors in vitro or in cell based models, but do exhibit estrogenic effects in animal models. It is our hypothesis that parabens exert their estrogenic effects, in

Parabene und Verbraucherschutz
Nachrichten aus der ChemieAbstract In den 2000er Jahren tauchte auf vielen Körperpflegeprodukten das Etikett „parabenfrei“ auf. Die Kosmetikindustrie reagierte damit auf Befürchtungen der Medien und Verbraucher, Parabene könnten krank machen. Welche toxikologischen Daten gibt es, und wie bewerten Studien und Fachgremien das Gesundheitsrisiko?

To the Editor.— In their Letter to the Editor concerning systemic eczematous "contact-type" dermatitis medicamentosa caused by parabens, Aeling and Nuss 1 report a paraben-sensitive individual whose dermatitis apparently was exacerbated following the injection of lidocaine (Xylocaine), which contains a paraben as a preservative.
