Polyquat-7 vs silicone in leave-on conditioner
Is is true that silicones can do everything poly7 can do? Are there any benefits polyquat could add?

@DaveStone PQ-7 is very useful in rinse off products, mostly cleansers from which PQ-7 can deposit on hair/skin and help other ingredients deposit (like some silicones). In a leave-on, since the product won’t be rinsed, you don’t need somethong as specific as a cationic polymer, and you can use silicones, esters and other type of emollients and cationic surfactants right away.

Agreed, for leave-on silicones are superior to polyquaternium 7
