  Ingredient Compatibility in a Formula

  Posted by Anonymous on May 13, 2019 at 12:27 pm

  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

  You use four ingredients with exfoliating properties in one product. One of them being retinol which is sensitising alone. Depending on % this product might be rather irritating. Impossible to say without seing the entire formula. If you use these ingredients at 0.01% for claims might be ok.
