We are constantly exposed to phthalates in our environment through plastic products such as storage containers, medical devices, packages, fabrics, and toys. Specifically, di-isononyl phthalate is inevitably becoming a part of our lives. Unfortunately, the impact of DiNP on the establishment and maintenance of pregnancy is largely unknown. In a new study, researchers used mice to understand how DiNP affects pregnancy.

Phthalates are commonly used to make products—including artificial leather, footwear, plastic food packaging, and personal care products—more flexible or stable. In particular, di-isononyl phthalate is incorporated in vinyl clothing and construction materials. However, scientists do not completely understand if or how it harms the human body. To do so, researchers looked at the effect of DiNP on the colonic environment in a new study.
