Uses

BBP is used as a plasticizer to make plastics more flexible and harder to break. It is often used in polyvinyl chloride (PVC) products, such as vinyl flooring, artificial leather, and some types of wallpaper. BBP is also used in the manufacture of food packaging, medical devices, and cosmetics.

Health Effects

Exposure to BBP can have several adverse health effects. It has been shown to disrupt the body's endocrine system, leading to hormonal imbalances.
