Benzyl butyl phthalate

Benzyl butyl phthalate (BBP) is a phthalate, an ester of phthalic acid, benzyl alcohol, and n-butanol. BBP is a clear liquid with the chemical formula C19H20O4. It is used in a variety of products, including vinyl flooring, adhesives, automotive trim, and plastic clothes.

Chemical Structure and Properties

BBP has a molecular weight of 312.36 g/mol. It is a colorless oily liquid that has a slight, sweet smell. It is not very volatile, does not burn easily, and can dissolve in water.

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. BBP can also affect the reproductive system, causing fertility problems in both men and women. Long-term exposure to BBP can lead to liver and kidney damage.

Regulation

Due to its potential health effects, the use of BBP is regulated in many countries. In the European Union, BBP has been banned in all toys and childcare articles since 1999. In the United States, the Consumer Product Safety Commission (CPSC) has banned the use of BBP in children's toys and childcare articles since 2009.
