Preservatives are needed for most cosmetic formulations that include water. There are some companies that have very stringent manufacturing procedures to ensure the hygiene of the product and the ratio of some of the materials may make the product quite stable against contamination. Shampoos can sometimes do this as they are often very alkaline, However, that alkalinity is not very comfortable on the scalp.
