Rosin allergens were found in all analyzed disposable diapers, with higher concentrations in top layers. This poses a risk of dermatitis for sensitive individuals using diapers, incontinence, or hygiene products.

Area of Science:

  • Allergy and Immunology
  • Environmental Health
  • Analytical Chemistry

Background:

  • Rosin, a natural resin, is a known source of allergens.
  • Exposure to rosin allergens can occur through various consumer products.
  • Disposable diapers are widely used by infants and adults.

Purpose of the Study:

  • To investigate disposable diapers as a potential source of rosin allergen exposure.
  • To quantify rosin components in common diaper products.
  • To assess the risk of allergic contact dermatitis from diaper use.

Main Methods:

  • Gas chromatography was employed to detect and quantify rosin compounds.
  • Disposable diapers available on the Swedish market were analyzed.
  • Rosin content was compared between different diaper layers and brands.

Main Results:

  • Rosin components were detected in all tested disposable diapers.
  • The highest concentrations of rosin were found in products from the two major manufacturers.
  • Greater amounts of rosin were present in the diaper's top layer, in direct skin contact.

Conclusions:

  • Disposable diapers contain rosin allergens, posing a risk for elicitation of dermatitis in sensitized individuals.
  • Skin contact, occlusion, and irritation can enhance allergen penetration.
  • The findings extend to adult incontinence and feminine hygiene products containing similar materials.
