If we use Amodimethicone in shampoo without cationic polymers, does pH of shampoo effect how much Amodimethicone deposit on hair?
I mean difference between pH 5 and pH 4.
Recently i made two sample of shampoo with 0.3% Amodimethicone conditioner without cationic polymers. One at pH 4 and another at pH 5. The combing and hair feel after the shampoo at pH 4 is better compared to the one at pH 5.
Shampoo is SLES/SLS/CAPB/APG with Amodimethicone emulsion (0.3% silicone)
Comments
This moety wil protonated depend on pH , more acidic , more protonated cationic side, and will higher deposition on anionic site on keratin/cuticle
