Formulating a Foaming Vehicle for a Topical Leave On?
Hi there, I’m new to cosmetic chemistry and chemistry in general (in University but hoping to go to cosmetic chemistry one day), however I’m interested in trying my hand at formulating a serum/leave on product in a foaming vehicle rather than a spray or serum texture. I was wondering what surfactants or other ingredients would be gentle for skin with eczema and psoriasis to help achieve this effect? I was planning to use foaming pumps rather than any sort of pressurized container, as it’s for my own personal usage. I wasn’t sure if solvents/humectants like butylene glycol or propenadiol would be enough to create a light foam. I’m trying to make it lightly foam specifically to make it more spreadable over a large surface area.
