Phthalates are a group of chemical compounds commonly used to make plastics more flexible and durable. They are often found in products like vinyl flooring, toys, and personal care items such as lotions and shampoos. Phthalates help improve the performance and longevity of these products. Concerns have been raised about the potential health effects of phthalates, as they can be absorbed by the body and may disrupt hormonal systems. Regulatory agencies, including the U.S. Environmental Protection Agency, have been studying their safety and have implemented restrictions on certain phthalates in children's products and cosmetics.
