Ingredient Compatibility in a Formula
I am a recent chemistry graduate working on a moisturizing cream and balm/salve duo, filled with actives and other effective ingredients. What factors do I need to look at to ensure compatibility of actives in the formula, e.g. making sure that the presence of one raw material/active doesn't interfere with the function of others.
Actives we are considering in the cream: Colloidal oatmeal, panthenol, Urea, Glycolic acid, neem, burdock, vitamin A, and vitamin E, Allantoin, Chamomile, Squalene, exfoliating papaya enzymes
Actives we are considering in the balm/salve: Lipids/ceramides, Rosehip, panthenol, Marshmallow root extract, calendula, niacinamide
