I’m using HEC to make this foaming hand soap feel nicer; I wanted a more moisturizing feel without sacrificing foam performance or clarity. I haven’t used HPMC in a formula before, but willing to try if it is more compatible with the system.
The product I’m making is very fragrance driven. After solubilizing with DPG, my fragrance percent comes out to around 1.3% which is still high, but… like I said, fragrance is key to the customer ¯\_(ツ)_/¯
