Page "Cosmetology" Paragraph 18

Dibutyl phthalate ( DBP ) is a common ingredient found in nail enamels and hardeners.

DBP is a plasticizer that is used because of its flexibility and film forming properties, making it an ideal ingredient in nail polishes.

When a polish is applied, it dries to the nail as some of the other chemicals volatilize.

DBP is a chemical that remains on the nail, making the polish less brittle and apt to crack.

The chemical may not only be absorbed through the nail, but through the skin as well.

When nail-polished hands are washed, small amounts of DBP can leach out of the polish and come into contact with the skin.

The application of nail polish can also provide an opportunity for skin absorption.
