"Drag" is hard to explain, but I'll try.
Imagine bathing and everything is fine.
You get out to dry off and it's almost like you're sticky.
The towel doesn't glide to dry you -- it sorta "drags and sticks"
When you get dressed, you can still feel the "stick" and the feeling
goes away in an hour or so.
I too suspect castor in the recipe, but I'm also suspecting a castor
and stearic acid combination -- not absolutely sure what causes it.
