Summary

This study identified key allergens in artificial nail cosmetics. Two specific acrylic compounds, 2-hydroxyethyl methacrylate and ethyl cyanoacrylate, are crucial for diagnosing nail cosmetic allergies in most patients.

Area of Science:

  • Dermatology
  • Cosmetic Science
  • Allergology

Background:

  • Artificial nail cosmetics frequently contain acrylic compounds.
  • Contact allergy to nail cosmetics affects individuals using artificial nails.
  • Diagnosing specific allergens in a clinical setting can be challenging due to the variety of ingredients.

Purpose of the Study:

  • To identify the most effective allergens for diagnosing contact allergy to acrylic-containing nail cosmetics.
  • To simplify patch testing protocols for dermatologists.
  • To improve the diagnostic accuracy of nail cosmetic allergies in clinical practice.

Main Methods:

  • Patch testing was performed on 27 patients with a history of contact with artificial nails.
  • Patients were tested for common acrylic compounds found in nail cosmetics.

  • Results were analyzed to determine which allergens elicited positive reactions.

    • Main Results:

    • 2-hydroxyethyl methacrylate and ethyl cyanoacrylate were identified as the primary allergens.
    • These two allergens were sufficient for diagnosing contact allergy in the majority of the tested patients.
    • One patient showed a reaction to an unidentifiable component in their nail preparation.

    Conclusions:

    • 2-hydroxyethyl methacrylate and ethyl cyanoacrylate are essential allergens for diagnosing acrylic nail cosmetic allergies.
    • A simplified panel including these two allergens can be valuable in dermatological practices.
    • Further investigation may be needed for cases with unidentified allergens in nail preparations.
