Seriously, we all (in the US and world) should have automatically known this.
There needs to be more widespread warnings and education regarding plug-in fragrances and diffusers.
The common person, obviously, doesn't know about the dangers simply because we (as a whole) haven't been properly informed/educated.
EDITED:
The only reason why I know....... is that I feel nauseated and my lungs slightly 'flutter' each time I pass a house that is reeking of that particular chemical that is used in dryer sheets and/or strong detergents.
Then I begin to think of how that precious newborn or child feels, smelling that odor in their bedding, pillow cases, etc.
Another thing that I've often mentioned is the fact that, around here, in my neighborhood we've been noticing that the strongest chemical odors (dryer sheets, detergents) reek out of houses that have newborns and fairly newly born children.
Saying just yesterday..........'OMG, that family just had a new baby, and can you smell that strong odor?'........We were walking across the street, and the odor was very strong.
Again, keep your newborns, children, and pets safe.
It's our responsibility.
