Cleansing surfactants

Also appears on labels as: sodium lauryl sulfoacetate, sodium laureth sulfate, sodium coco-sulfate, coco-glucoside, cocamidopropyl betaine, cocamidopropyl hydroxysultaine

Molecules with a water-loving end and an oil-loving end. They lift grease and dirt so it can rinse or wipe away.

Watched ingredients get highlighted on every product panel you open.

Where it comes from: Mostly coconut and palm oil derivatives, chemically modified.
Why it's in the product: The part of a shampoo or a cleaner that actually cleans.
Safety and toxicity: A wide gentleness range. Glucosides and betaines are mild; sulfates clean harder and strip more oil, which matters for a dog with dry or irritated skin. Sodium lauryl sulfate has a reputation as a toxin that is not supported. It is an irritant at concentration, not a poison. Cocamidopropyl betaine is a known contact allergen in a minority of individuals.
Interactions and who should be careful: Human shampoo is the real hazard here, not any of these ingredients. Dog skin has a different pH, and human product used regularly disrupts the barrier.
