Hi, I need some help on a hand soap formulation. I don't have a formula yet, I need some advice in the choice of the raw materials.
- what is the percentage of surfactants recommended in a foaming hand soap? I was thinking to use cocoamidopropyl betaine and coco glucoside. I have tried some starting formulations. They advice a large amount of surfactant that I think made the formula difficult to rinse and to aggressive to skin.
- what is a good moisturiser? the hand soap will contain benzalkonium chloride and then I need something compatible with it.
- what I can use to have a creamy foam for the same product?
thank you in advance
