Ingredients with an actual dermatological job: allantoin soothes, salicylic acid (a beta hydroxy acid) lifts scale, lanolin conditions, sulfur is antimicrobial and antiparasitic.

Watched ingredients get highlighted on every product panel you open.

Where it comes from
Synthesis, or wool grease in the case of lanolin.
Why it's in the product
Medicated shampoos for seborrhea, dandruff, and flaky skin.
Safety and toxicity
Effective and generally well tolerated at shampoo concentrations. Salicylates are the caution for cats specifically: cats metabolize salicylates poorly, and while a rinsed-off shampoo is a very different exposure from an oral dose, it is a reason to use a cat-labeled product on a cat.
Interactions and who should be careful
Never use a dog shampoo containing salicylic acid or permethrin on a cat without checking. Permethrin in particular is a common and serious cat poisoning.
