I am developing Rinse off Hair Conditioner.
I have seen some of the Bench mark formulary & net formulary so I have observed that generally in formulation Stearamidopropyl dimethylamine are there , Lactic acid also are there.
I read the literature of Stearamidopropyl dimethylamine in that they have mentioned that for optimum solublity we have to use Acids like citric acid or lactic acid.
Stearamidopropyl dimethylamine is an effective conditioning agent after being neutralized with an acids like citric acid, Lactic acid or Glutamic acid.
I want to know that any particular reason that people are using only lactic acid ?
