Everyday chemistry, named

Short, calm pages on everyday chemistry. Educational. Not a diagnosis. The full map lives in Endocrine Disruptors.

• What are endocrine disruptors?Hormone messages. A traffic pattern, not one poison and not a cleanse.
• What leaves, and what staysSome clear in days if you stop adding them. Some stay for years. A tea does not sort that.
• Fragrance and phthalatesLeave-on scent is louder than one wash-off. Quiet the next bottle.
• Thermal paper receipts and parking ticketsThe coating can carry BPA or BPS. Decline when you can. Wash before you eat.
• Squishy toys and scented vinylIf it smells like a factory, that is data. Wash new plastic. Kids still get to play.
• Microwave and plasticHeat is the multiplier. Never microwave in plastic. Empty, then heat.
• Hair dye, relaxers, gel nailsFrequency is the lever. Not vanity as a moral failing.
