Aluminium in deodorant: the breast cancer headline has weakened in 2017–2024 evidence. Here's what the science says now and the honest case for switching.
Fragrance in products is one word that legally hides up to 3,691 chemicals. The EU now requires 80 of them disclosed. The US still requires zero.
Oxybenzone sunscreen exceeded the FDA's own safety-testing threshold within two hours of a single application — and stayed above it three weeks later.
Flame retardants migrate from foam furniture into dust into people. Cats in the same homes carry 20-100x more than humans. Here's what the evidence says.
Chlorine in tap water saves lives by killing pathogens. The byproducts it leaves behind are a different question. Here's what the evidence says — and what to do.
Atrazine in tap water peaks 3-7× the EPA limit during runoff season — and the limit is an annual average. Here's what the evidence says.
VOCs in home air run 2-5x higher than outdoor air, and 1,000x higher during paint stripping. Where they come from, what the evidence says, and what to do.
Toluene is the solvent in nail polish, paint thinner and petrol vapour. It isn't a carcinogen — its harm is to nerves and to the developing fetus.
DMDM hydantoin is a cosmetic preservative that slowly releases formaldehyde inside the bottle. Here's what it is, where it lives, and which regulators have moved.
Chemical combination effects: the gap regulatory testing misses. Eight weak chemicals, each below its no-effect dose, still combine into a substantial response.
Why 'safe dose' chemicals aren't always safe: the regulatory dose-response model uses three data points to draw a curve hormones don't follow.
What's actually in chemical sunscreen — and what the FDA's own trial found when six of those chemicals were tested for absorption, persistence, and safety.
Deodorant stacks six EDC families on one patch of skin and you apply it 18,000 times. Here's what the evidence says — chemical by chemical.
Non-stick cookware is a PTFE coating over aluminium. Intact + low-medium heat = mostly inert. Scratched + empty + preheated = a different conversation.
Castor oil toothbrush bristles are nylon. The UK ASA ruled the marketing misleading. The brand that got caught dissolved. The websites kept selling.
Around brackets, bristle engineering — diameter, end-rounding, head profile — matters more than bristle origin. Here is what the evidence shows.
What's in toothpaste? Eight ingredients worth knowing — SLS, triclosan, fluoride, titanium dioxide and more. The evidence is uneven, and so is the regulation.
A pea-sized smear holds 0.25 mg of fluoride. The probably-toxic dose for a 15 kg toddler is 75 mg — about 300 peas. What the evidence actually says.
GenX replaced PFOA in 2015 and clears 380× faster — but matched-design studies show parallel placental effects, and the EPA's limit is contested.
GenX is a Chemours trade name. The chemical is HFPO-DA — the short-chain PFAS that replaced PFOA in non-stick coating production in 2009. Plain-English explainer.
GenX clears your blood in 81 hours and persists in groundwater indefinitely. Why one short half-life got sold as evidence for two very long ones.
GenX endocrine disruption isn't via classical hormone receptors — it's PPARα-mediated metabolism plus thyroid axis effects. Here's what the rodent evidence shows.
GenX was in Wilmington's tap water at 631 ng/L for at least eight years before residents found out. The Cape Fear timeline is what 'compliance' looked like.
Electric toothbrush heads are too small and too mixed to go in kerbside recycling. Some brands take them back — but recyclable isn't plastic-free.
