Xenoestrogens are chemical compounds that are not naturally found in nature. These foreign chemicals are usually found in polyvinyl chloride (PVC) plastics and organochlorines. Xenoestrogens are found in many plastic food containers, such as yogurt, juice, milk, baby bottle and water container. They are also found in pesticides, detergents, bleached products and makeup. These chemicals are so popular that there are more than 100,000 xenoestrogens in use today.
