MYTH: Natural preservatives work just as well as traditional or synthetic preservatives.

FACT: “Natural” preservatives such as essential oils (i.e. thyme oil and rosemary) generally require greater amounts than are usually needed for traditional preservatives. These high levels can affect cleaning performance, fragrance and color.  Natural oils may be irritating and may cause allergic reactions in some users.  Other “naturals” such as organic acids may not be compatible with hard surface cleaners and detergents.
