I'm trying to make an oil cleanser and so far I've just mixed oils like grapeseed, sunflower and a couple more. However, when I look at formulations of other cleansing oils, I see that Caprylic/Capric Triglyceride, pentylene glycol, stearyl glycyrrhetinate etc are included as well. Do I require all these? Do I require a preservative like phenoxyethanol or cleansing agent like sorbeth-230 tetraoleate? Capric Triglyceride is used to replenish skin but I don't see why skin replenishment is required while cleansing with an oil cleanser (no moisture loss happens)? I'm sorry if this is dumb, I'm just super confused cuz I know some of these ingredients are for thickening purposes but I don't really want to thicken the oil as its supposed to effortlessly slide onto the skin while removing makeup! Send help!
