Is it removed from hair easily, and does cause build-up problems?
From what I am reading it is not water soluble?

Suzanne, yes, it is not water soluble, so it can create some buildup overtime. But you can easily remove it by using a clarifying shampoo every once in a while.

It is clearly water soluble …. Hense 19% dissolved in water is one form you can buy it and the other is 50% dissolved in alcohol, I formulate hair products for a living and can tell you with a gentle stir this chemical can be added into water with no other emulsifier’s.
