Does washing or rinsing hair with water alone remove cationic polymer or silicone from hair
If we wash our hair or rinse it with water alone, can it remove cationic polymer like cationic guar, dimethicone, Amodimethicone or glyceryl oleate from hair?
If yes, then ok
If no, then does the amount of rinsing after shampooing effect how much polymer and silicone remain in hair and how much is washed if shampoo has cationic guar and Amodimethicone?If no, then ok
If yes, then why and how? -

Hmm well, I guess it’s likely that you can rinse Cationic Products from your hair with water alone due to the fact that they are in general soluble in water. The amount that gets taken off is not completely as we can see in the different tests that show that cationic polymers in shampoo help with combability. but I would guess the longer you Rinse off the more is taken off.
for Silikons that is different silicons will not be washed off easily with just water, you can try that by putting the silicon on the back of your hand and look how long, it will take until all the silicone is rinsed off. It’s the “big” issue with silicon in hair care Products it can lead to a build-up if used too much.

Thanks
So you mean if a Shampoo has cationic guar and Amodimethicone, rinsing more doesn’t mean less silicone will deposit?

silicon will deposit as far as it is not already solubilized by your surfactant if it deposits it will Stay on the Hair better.
For Cationics the more you rinse the more will be washed off.
That’s at least my understanding of Solubility and Adhesion on the hair.
If someone has a deeper understanding interested to hear it.

I don’t think water would be able to remove cationic polymers (unless you add a lot of salt). Cationic polymers, especially the ones with higher charge density, would prefer to remain bound to hair (unless ionic strenght or pH changes). Also, in shampoos, they deposit as coacervates, which are harder to remove from hair. Even rinsing with surfactants leave some amount of cationic polymers (or coacervates) on hair.
Uncharged silicones (like dimethicones) are of course not possible to be removed by water (they are not soluble in water), but they are easily removed by surfactants. The same would hold for cationic silicones, although they might be a bit harder to remove with surfactants than uncharged ones. Keep in mind that they are still very hydrophobic molecules (unlike water soluble cationic polymers), so detergents would do a good job on removing them.

@ketchito so if a Shampoo has cationic guar+Amodimethicone, rinsing more will not reduce the amount of silicone+polymer deposited in hair. Am i correct?

@Abdullah If it’s just plain water, it shouldn’t.
