PFAS in Tampons: What the Research Actually Shows
The evidence on PFAS in tampons is mixed. The cotton core is usually clean; fluorine shows up mostly in applicators and wrappers.
Microplastics in Tea Bags: What the Research Shows
Yes, plastic and silken tea bags shed billions of microplastics in hot water. Paper and loose leaf shed far less.
Microplastics in Bottled Water: How Much, and Should You Worry?
Yes, bottled water contains microplastics and nanoplastics. One liter holds about 240,000 plastic particles.
Is Silicone an Endocrine Disruptor?
Mixed. Solid food-grade silicone is largely inert, but cyclic siloxanes (D4, D5, D6) act as endocrine disruptors.
Is Rosemary Oil an Endocrine Disruptor?
No, rosemary oil is not a proven endocrine disruptor at normal use. The hormone findings come from concentrated extracts in the lab.
Is Phenoxyethanol an Endocrine Disruptor?
No, phenoxyethanol is not a proven endocrine disruptor at the levels used in cosmetics.
Is Lavender an Endocrine Disruptor?
Lavender shows weak hormone activity in lab tests and a few case reports, but population studies disagree.
Is Coconut Oil an Endocrine Disruptor?
No, coconut oil itself is not a proven endocrine disruptor. The hormone worry is really about phthalate contamination in some products.
Does Silicone Have Microplastics?
Mostly no. Silicone resists shedding classic microplastics, but it can release particles under abuse and leach siloxanes when heated hot.
Does Dental Floss Contain PFAS?
Yes, some dental floss contains PFAS. Smooth glide-style floss is the main culprit, while nylon, silk, and wax-coated floss usually are not.
