Di-isodecyl phthalate (DIDP)
Posted June 2017
Why am I being warned about potential exposure to DIDP?
What is DIDP?
- DIDP belongs to a family of chemicals called phthalates, which are added to some plastics to make them flexible.
- DIDP is used in various types of plastic consumer products, including:
- Some polyvinyl chloride (PVC, vinyl) tubing, materials used in automobile interiors, garden hoses, raincoats, binders, storage cases, tile flooring, shower curtains, and bath mats.
- California law prohibits the manufacture, sale, or distribution of toys and child care articles intended for the use of a child under 3 years old, if that product can be placed in the child’s mouth and it contains DIDP at levels greater than 0.1%. US law currently has a similar prohibition.
How does exposure to DIDP occur?
- DIDP can be gradually released from consumer products into indoor environments such as homes and cars. It settles on floors and other surfaces, and can accumulate in dust and air.
- During pregnancy, DIDP can pass from mother to baby.
How can I reduce my exposure to DIDP?
- Avoid plastics known as polyvinyl chloride (PVC) or vinyl (with recycle code 3).
- Minimize exposure to dust, which can contain DIDP:
- Wash your hands and your child’s hands frequently, especially before preparing food and eating.
- Clean floors regularly, using a wet mop if possible, or a vacuum with a high-efficiency particulate air (HEPA) filter.
- Wipe up dust regularly, using a damp cloth.
