I am experimenting with sepimax zen. By the end of preparation if I am not ok with consistency I add more of gelling agent. But this makes the formula more than 100%. So can I leave some room for water and can that be added after I finalize the amount of gelling agent?
For instance The final make up volume with water was 80%.I used 79% of water and as per my formula 0.5% of zen and later added 0.2% more. Left it overnight to hydrate and when stirred I was fine with consistency. Then I added the balance 0.8% water. Am I doing right? Is this the way to do?
Similarly even for pH adjustment how can it be done after getting the end product. Should I first adjust pH of water phase and then go for emulsification? If at the end pH of cream alters how do I adjust without not exceeding 100%. And also will the added adjuster go into the cream without seperating?
