Formulating Shaving Cream
Hello! I am trying to formulate soap-based shaving cream which I can put in a bottle with a pump. A am using a process, where I first create a liquid soap with KOH, Stearic acid Coconut, and Olive oils, then mix it with some plant extracts gelled with Hydroxyethyl Cellulose, and at the very end, I add more Stearic acid, glycerin, and lots of Myristic acid. At first, I get a very nice creamy soap, shiny and flowing, but in several hours it became a foam, which is not possible to put in a bottle or to store for a long time. Could you help me to understand what is happening? Is it because the saponification process continues to happen (the final pH is 9.5), or this is simply because I put too much air in the cream while stirring it?

PH 9.5 is normal for liquid soap. It appears that adding HEC creates foam, you probably have too much air. Let is rest for a couple of days.
