Calcium Stearate

1) Scum
2) A white, powdery substance (C36H70CaO4, learned about in GCSE triple chemistry) made by soap (C18H35NaO2) reacting with permanent hard water ions ("Ca2+") to make "lathering" much more difficult. This is not to be confused with scale, which is made by boiling temporary hard water.

1) Politicians? Utter bags of Calcium stearate, they are!
2) In South England, we have mostly hard water. Yes, it lines the bath with calcium stearate sometimes, but the nutrients are great.

Lunch Lady: What would you like to drink with that?

Lunch Lady: What is that?

Eater: Chocolate milk.
