Antiseptic foaming solution
Hello everyone.
I am formulating antiseptic foaming solution that contains hexamidine, chlorhexidine and p-cresol.
The solution is colorless and clear after preparing. However, it turned red and precipitated after after 2 days.Can anyone help me?
I use propylene glycol to dissolve P-cresol and hexamidine.
Is it possible to use ethylene glycol to dissolve hexamidine and -cresol
I use Hydroxy Ethyl Cellulose to increase solution thickness.
I use cetrimide and tween-20 as soap baseI didn’t use anionic surfactant because of antiseptics incompatibility with anionic surfactant.
Any suggestions?
Thank you very much.
