"Endocrine disruptor" is a phrase that turns up a lot in headlines, often with more alarm than explanation. This guide sticks to what reputable health bodies actually say: what these chemicals are, where they're found, and the simple, sensible steps they suggest. It's general information, not medical advice. If you have concerns about your health, talk to your GP.

What are endocrine disruptors?

Your endocrine system is the network of glands that make hormones, the chemical messengers that help regulate growth, metabolism, reproduction and more. Endocrine-disrupting chemicals (EDCs) are substances from outside the body that can interfere with that system.

The US National Institute of Environmental Health Sciences (NIEHS) describes three main ways they can act:

  • Mimicking a natural hormone
  • Blocking a hormone from doing its job
  • Interfering with how hormones are made, moved or broken down

The World Health Organization notes that children and developing babies may be more sensitive to some environmental chemicals, which is why much research focuses on pregnancy and early childhood.

Which chemicals are we talking about?

The Endocrine Society and the Endotext medical reference list several well-studied groups:

  • Bisphenols, such as BPA: used in polycarbonate plastics and some can linings.
  • Phthalates: used to make some plastics, like PVC, soft and flexible, and in some fragrances.
  • PFAS: used in some non-stick, stain-resistant and water-repellent products.
  • Legacy flame retardants and industrial chemicals, such as PBDEs and PCBs, found in some older products and materials.
  • Certain pesticides.

Some plant compounds, called phytoestrogens, can also weakly act like oestrogen. They're generally considered a separate category from industrial chemicals.

What does the research say?

The research is active and still evolving. Studies have looked at links between some EDCs and reproductive, metabolic and developmental outcomes, and the peer-reviewed literature on EDCs and reproductive health is growing.

It's also worth knowing the limits. People are exposed to many substances at low levels over long periods, which makes it hard to show that any single chemical causes a particular effect. Many findings are associations rather than proven causes, and scientists are still studying how mixtures of chemicals behave together. Being calm and informed is more useful than being alarmed.

How are they regulated in Australia?

Australia doesn't have one dedicated framework for EDCs. Instead, several regulators cover different types of chemicals:

  • Food Standards Australia New Zealand (FSANZ) covers food and food-contact issues, and has published information on chemicals such as BPA in food.
  • The Australian Industrial Chemicals Introduction Scheme (AICIS) regulates industrial chemicals.
  • The Australian Pesticides and Veterinary Medicines Authority (APVMA) regulates agricultural and veterinary chemicals.

The European Union has gone further in setting formal criteria for identifying endocrine disruptors in some areas of law.

Simple habits health bodies suggest

You can't avoid every chemical, and you don't need to try. These are common-sense habits based on general guidance from bodies such as NIEHS:

  • Be thoughtful with heat and food packaging. Follow the instructions on containers and wraps, and use microwave-safe dishes for reheating.
  • Keep dust down. A damp cloth captures dust rather than spreading it around, and regular vacuuming helps.
  • Wash hands before eating, especially for kids who've been playing on the floor or outside.
  • Read labels on personal-care and cleaning products, and choose ones that fit your household.
  • Wash fruit and veg before eating.
  • Ventilate rooms with new furniture or after cleaning.

If you're pregnant or planning a pregnancy and have specific concerns, your GP or midwife is the best person to ask.

Where ZERO fits in

We're not going to tell you our products protect your hormones. That's not a claim we can or should make. What we can do is be clear about what our products are made of, so you can make your own choices.

  • ZERO Cling Wrap (from $6.99) is made from bioplastic: mainly PLA made from sugarcane, with about 20% PBAT for stretch. It's certified home compostable. Follow the usage guide on the pack. More in cling wrap and BPA.
  • ZERO Resealable Food Storage Bags (from $4.99) are made from PBAT, corn starch and calcium carbonate. They're tested for food contact, freezer-friendly and certified home compostable.
  • ZERO Baby Wipes (from $2.99) are dry wipes made from timber viscose (wood pulp). Nothing added, just water. They're OEKO-TEX® STANDARD 100 Class 1 certified, meaning they've been tested for harmful substances to the strictest class, the one for baby articles. Because they're dry, there are no preservatives or fragrance.
  • ZERO Reusable Cleaning Cloths (from $11.99) are made from timber viscose. They're absorbent and reusable.

FAQ

What is an endocrine disruptor?

A chemical from outside the body that can interfere with the hormone system by mimicking, blocking or disrupting hormones.

Can I avoid endocrine disruptors completely?

No, and health bodies don't suggest trying. Simple everyday habits are a sensible approach.

Does PLA contain BPA?

No. PLA is made from lactic acid, not bisphenol chemistry.

Who regulates these chemicals in Australia?

Several bodies, including FSANZ (food), AICIS (industrial chemicals) and the APVMA (agricultural and veterinary chemicals).
