Effect of HPMC on deposition of conditioning ingredients on hair from conditione
a conditioner has only 0.2% cationic guar and 1% solid amodimethicone (in emulsion form) in water at ph 4.5. it is almost water thin.
If i increase viscosity with 1% guar gum or HPMC, will it reduce the deposition of cationic guar or amodimethicone in hair?
Product is applied to hair after shampooing and then rinced

Since HPMC is non ionic, in a conditioner, I don’t think it would impair or increase those cationics deposition. Now, Cationic guar could compete with your cationic surfactant (which hair conditioners usually have).

This conditioner doesn’t have cationic surfactant.
It only has silicone. And i add this cationic guar to help with wet combing.
It is much easier to make than an emulsion conditioner with cationic surfactant.

Yes, but at the interphase of the emulsion, cationic surfactants are more active, both to deposit and to help other stuff deposit. That’s why they are they so widely used in conditioners, not to mention the lamellar gel benefits when deposited on the surface along with fatty alcohols, and the unpleasant overconditioning (buildup) cationic polymers bring over time.

Thanks
I will keep them in mind.
