Thin layer of foam from liquid hand wash
I am a beginning of cosmetic science. I am working on formulating a liquid hand wash. A thin layer of foam arise from the hand wash overnight. May I know how I can avoid the foam from building up?
Here is my formulation.
Hence, what is a good practice to dissolve SLS? I am currently dissolving 25-30% SLS in water under 65C-70C.
