No ingredients containing phthalates are used in iS Clinical products. However, phthalates are so widely found in the environment that it is impossible to avoid exposure to them. Phthalates are found in so many products of all sorts that we cannot assure the user our products are phthalate-free. Our products, however, would be expected to contain only minute amounts of phthalates. The highest amounts of phthalates are obtained from the foods we eat. Another source for children, is plastic toys which may be chewed on.
