Our suppliers use elemental chlorine-free processes that do not result in the formation of dioxin. The methods we use to analyze for dioxin are the most advanced government-approved testing methods available and can detect even minute amounts of dioxin, if present. Purification of the pulp fibers used to make Pampers and Luvs is done to eliminate the impurities which would inhibit our ability to make clean absorbent fibers. By cleaning the fibers in this manner, we can make a better performing product with fewer raw materials, which has clear benefits for the environment. Whitening the fibers is a result of this process, but is not its goal.
