Similarly, many antitussives (cough suppressants) and sore-throat medications do not need to come into contact with the throat to be effective. However, they are usually supplied in syrup form (even the yucky-tasting ones) because people prefer the physical assurance of the syrup, despite it conferring no medical benefit.
On a similar note, shampooes don’t have to lather at all. In fact, it’s often the unnecessarily harsh ones that lather the most. (Those sneaky shampoo making bastards)
The toothpaste ingredient is called sodium lauryl sulfate, in case you are wondering, or Googling for this comic. Dorothy obviously had well-studied friends in the chem department
It also might be because cats lack the tastebuds to taste sweetness, but who knows if this applies to giant anthropomorphic cats? Someone should publish a study on that..
One more problem with sodium lauryl sulfate (SLS) is that it can cause irritation that may contribute to canker sores. If you frequently get canker sores on your gums and inside your cheeks then try a toothpaste without SLS.

I love this comic because it is willing to talk about things like toothpaste foaming agents.

Wait…is this true? Is the actual cleaning from the brushing, not the foam?

k: They don’t HAVE to, but with shampoo the lathering effect is there to make a small amount go much further.
