Question - Liquid laundry detergent “pods” are commonly used household products. What are the typical chemical constituents of these “pods” and what are the mechanisms of toxicity following ingestion of these “pods”?
Answer- The cited article notes “Capsules [pods] typically contain anionic surfactants (20–35%), non-ionic surfactants (10–20%), propylene glycol (8–20%) and ethanol (2–5%) within a water-soluble polyvinyl alcohol membrane.” Regarding the mechanisms of toxicity, these authors note “Non-ionic surfactants are the primary mechanism, though anionic surfactants, ethanol and propylene glycol may also contribute.” (Day R et al.
