Allergic contact dermatitis to propyl gallate.

G Bojs1, B Nicklasson, A Svensson

  • 1Department of Dermatology, Central Hospital, Kristianstad, Sweden.

Contact Dermatitis
|November 1, 1987
PubMed
Summary

Propyl gallate, an antioxidant found in moisturizers, triggered allergic contact dermatitis in a patient with prior gallate sensitization from bakery work. This highlights potential cross-reactivity and occupational exposure risks.

Area of Science:

  • Dermatology
  • Allergology
  • Occupational Health

Background:

  • Propyl gallate is a widely used antioxidant in cosmetics and food products.
  • Allergic contact dermatitis (ACD) is a common delayed hypersensitivity reaction.
  • Occupational sensitization to chemicals is a significant concern in various industries.

Observation:

  • A patient previously sensitized to gallates developed ACD after using a moisturizing cream containing propyl gallate.
  • The patient's sensitization history was linked to occupational exposure in a bakery environment.

Findings:

  • Propyl gallate acted as a contact allergen in a sensitized individual.
  • The case suggests potential cross-reactivity among gallates.
  • Occupational exposure in bakeries can lead to sensitization to gallates.

Implications:

  • Cosmetic formulations containing propyl gallate may pose a risk to individuals with pre-existing gallate sensitivity.
  • Awareness of occupational gallate exposure is crucial for preventing sensitization.
  • Further investigation into gallate cross-reactivity is warranted.
