Di-n-butyl Phthalate (DBP)

Why am I being warned about potential exposure to DBP?
  • DBP is on the Proposition 65 list because it can cause birth defects or other reproductive harm. 
  • Exposure to DBP during pregnancy may affect development of the child, and may also harm the male and female reproductive systems. 
  • Proposition 65 requires businesses to determine if they must provide a warning about exposure to listed chemicals.
What is DBP?
  • DBP is an oily liquid that belongs to a family of chemicals called phthalates, which are added to some plastics to make them flexible. 
  • DBP is used in various consumer products, including:
    • Some wire and cable insulation, gloves, tubing, garden hoses, shoes, and personal care products, including some perfumes and other products containing fragrances, and nail polishes.
  • California law prohibits the manufacture, sale, or distribution of children’s toys and child care articles containing DBP at levels greater than 0.1%.  Federal law has a similar prohibition.
How does exposure to DBP occur?
  • DBP can be absorbed into the body through contact with DBP-containing cosmetics household products and other products.
  • DBP can be gradually released from consumer products into indoor environments such as homes, schools, daycare centers, and offices.
  • During pregnancy, DBP can pass from mother to baby.
1. Breathing in DBP present in air and dust 2. Transferring DBP from hands to the mouth and swallowing 3. Absorbing through skin from DBP-containing products
How can I reduce my exposure to DBP?
  • Avoid plastics known as polyvinyl chloride (PVC) or vinyl (with recycle code 3).
  • Choose personal care products that are identified as “phthalate-free” or “fragrance-free”.
  • Minimize exposure to dust, which can contain DBP:
    • Wash your hands and your child’s hands frequently, especially before preparing food, and before eating.
    • Clean floors regularly, using a wet mop or a vacuum cleaner with a high-efficiency particulate air (HEPA) filter, if possible.
    • Wipe up dust regularly, using a damp cloth.
