Phthalates (DEHP / DBP / BBP / DEP)
Toxins · Endocrine disruptor
Moderate priority
Bottom line
Read Off Label rates Phthalates (DEHP / DBP / BBP / DEP) a MODERATE avoidance priority (6.2/10) based on moderate-strong evidence of med-high harm magnitude and moderate chronic ubiquitous exposure prevalence.
Ubiquitous in body fluids in NHANES — virtually 100% prevalence.
The intervention here is reducing exposure, not adding a compound.
What this is
Ubiquitous in body fluids in NHANES — virtually 100% prevalence. 'Fragrance' on ingredient lists usually means phthalate carriers. Shanna Swan's 2021 book 'Count Down' popularized male reproductive concerns around phthalates and sperm count decline — some controversy about magnitude but concern is legitimate.
Mechanism
Plasticizers in vinyl (PVC), flexible plastics, personal care products (fragrance, nail polish); anti-androgenic in males; developmental effects; near-universal urinary metabolites
Dose & route
Fragrance-free personal care; avoid vinyl shower curtains/kids' toys; don't microwave plastic; avoid PVC food storage
