Potential Allergens in Wound Care Products.

Area of Science:

• Dermatology
• Wound Care
• Allergology

Background:

• Patients with chronic wounds are at higher risk for allergic contact dermatitis (ACD).
• ACD from wound care products is frequently reported.
• Minimizing allergen exposure is crucial for patients with chronic wounds.

Purpose of the Study:

• To identify common allergens in wound care products.
• To guide clinicians in selecting products that minimize allergen exposure for patients with chronic wounds.

Main Methods:

• Cross-referencing ingredients of 267 wound care products from 5 clinics with the American Contact Dermatitis Society core allergen series 2020.
• Categorizing products by type (dressings, medications, tapes, etc.) and identifying the presence of allergens.

Main Results:

• 36.3% of analyzed wound care products contained at least one allergen.
• Tapes/glues (80%) and odor-eliminating products (66.7%) had the highest prevalence of allergens.
• Acrylates and propylene glycol were the most common allergens, followed by parabens, cetyl stearyl alcohol, tocopherol, fragrance, and phenoxyethanol.

Conclusions:

• A significant number of wound care products contain contact allergens.
• Educating clinicians on ACD and wound care product selection is essential to minimize patient sensitization.
