Irritant contact dermatitis occurs more often than allergic contact dermatitis. You develop a rash when a chemical substance irritates the skin’s outer layers. The rash is more painful than itchy.

Common causes of irritant contact dermatitis include:

• Acids.
• Alkalis like drain cleaners.
• Body fluids, including urine and saliva.
• Certain plants, such as poinsettias and peppers.
• Hair dyes.
• Nail polish remover or other solvents.
• Paints and varnishes.
• Harsh soaps or detergents.
• Resins, plastics and epoxies.
