According to the ingredient table, which family causes the primary reaction type Irritant (ICD)?
Answer
Surfactants/Detergents
The comparison table clearly delineates ingredient families by their primary reaction type. Surfactants and Detergents, which are the active cleaning agents found in dish soap, laundry detergent, and harsh cleansers, are explicitly associated with the Irritant Contact Dermatitis (ICD) reaction type. This aligns with the mechanism of ICD, as these compounds aggressively strip natural skin lipids and disrupt the barrier function through their primary cleaning action. In contrast, the other options listed—metals, fragrances, and topical medications—are categorized primarily as chemical sensitizers leading to Allergic Contact Dermatitis (ACD).
