Di-n-hexyl Phthalate (DnHP)
Posted September 2017
Why am I being warned about potential exposure to DnHP?
What is DnHP?
- DnHP is an oily liquid that belongs to a family of chemicals called phthalates, which are added to some plastics to make them flexible.
- DnHP may be used in some vinyl products although its use has decreased.
How does exposure to DnHP occur?
- DnHP can be gradually released from consumer products into indoor environments, such as homes and offices. It settles on floors and other surfaces, and can accumulate in dust and air.
- Exposure can result from contact with products containing DnHP.
How can I reduce my exposure to DnHP?
- Avoid plastics known as polyvinyl chloride (PVC) or vinyl (with recycle code 3).
- Minimize exposure to dust, which can contain DnHP:
- Wash your hands and your child’s hands frequently, especially before preparing food and eating.
- Clean floors regularly, using a wet mop, and a vacuum with a high-efficiency particulate air (HEPA) filter, if possible.
- Wipe up dust regularly, using a damp cloth.
