We often receive questions on preservatives. Different product types, like creams vs. liquids, need different preservatives that work best for a particular formula. The chart below shows where we use and do not use the major classes of preservatives found in most consumer products. All of our preservatives comply with applicable regulations and safe limits wherever they are sold. Please contact us if you need more details on the preservative used in a particular product and we will be glad to assist you.
