Hi everyone,

Need to know your recommendations for the best Rehodology modifier to get Gel based like carbomer for Chlorhexidine Digluconate 0.2% and Ethanol 70%.

    For 70% ethanol, only PVP comes to my mind (though my mind isn't working properly, it's been a long day at work).

    Agree with @Bill_Toge, I have used HPMC though and it came out pretty nice. But comparatively still on lower side of viscosity. I tried Methocel 40-202, you can try 40-101 grade which has higher viscous.  But mine was alcohol free with either benzalkonium chloride or CHG.
