Formulation for clear gel toothpaste.
I am trying to formulate a transparent (maybe translucent) toothpaste. I used Sorbosil TC15 (Hydrated silica) for binder/thickener but percentage up to 8% still dont build desired viscosity. So i tried Carbopol 980 with 0.5%, then i got problem with disperse Carbopol because my formula is too little water (8%), rest of solvent is sorbitol and glycerine (72%).
Can anyone give me some advice for disperse Carbopol? May i disperse Carbopol in ethanol before hydrating? My formula dont have any oil phase for disperse carbopol. And i use Sodium CMC for thicker already.
Thank for your help.
P/s: When change from Sorbosil to Carbopol, i substitute Benzyl alcohol for Sodium Benzoate. Is toothpaste formula okay with benzyl alcohol?
