I would like to formulate a cleansing product similar to Dermalogica's Microfoliant. LOI: Microcrystalline Cellulose, Magnesium Oxide, Sodium Cocoyl Isethionate, Sodium Lauroyl Glutamate, Colloidal Oatmeal, Disodium Lauryl Sulfosuccinate, Oryza Sativa (Rice) Bran, Oryza Sativa (Rice) Starch, Allantoin, Papain, Salicylic Acid, Ginkgo Biloba Leaf Extract, Camellia Sinensis Leaf Extract, Glycyrrhiza Glabra (Licorice) Root Extract, PCA, Hydrolyzed Wheat Protein, Populus Tremuloides Bark Extract, Cyclodextrin, Lauryl Methacrylate/Glycol Dimethacrylate Crosspolymer, Melaleuca Alternifolia (Tea Tree) Leaf Oil, Limonene, Citrus Grandis (Grapefruit) Peel Oil, Citric Acid, Titanium Dioxide (CI 77891) , Hexylene Glycol.
If this product were to be marketed toward individuals with sensitive skin (including thosr with conditions like acne, eczema, rosacea, etc.) is it necessay to use irradiated colloidal oatmeal or is that overkill if the product is anhydrous? In what situations is irradiated colloidal oatmeal used in cosmetics? Or is it solely for pharmaceutical applications?
