Polyquaternium 10
Polyquaternium 7
Guar hydroxypropyltrimonium chloride -

@Abdullah While the three of them work better at reducing charge density which is more perceivable at static reduction under dry conditions, PQ-10 and Guar HPTC are modified polysaccharides that form a rigid film on hair, while PQ-7 being a copolymer, has more degree of freedom. What I mean is that even though the three are more for dry effect on hair, PQ-7 has a little influence on wet combing as well. Nevertheless, silicones are superior on both wet and dry combing, and can be used alongside (except cationic silicones) or replacing them.

@ketchito and what is a good silicone for this purpose?
I am going to purchase some 5 cst dimethicone for lotion. Is it good in Shampoo too? At what percentage? -
@Abdullah It depends on your formulation. If you have a stabilizer (like some Carbopol), then you can use fluid Dimethicone (I’d go for a 350 or 1000 cst viscosity). But if not, a Dimethiconol emulsion can also perform well (only, the deposit will be less). For instance, DC 1784 or 1785 can be used.

I’ve never been able to demonstrate a difference. It’s one of those things you have to test yourself in your system.
