Does pH of shampoo effect the deposition of Amodimethicone from Shampoo
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)
