These are BAD, mkay?:

Alcohol Denatured

  • Cancer, Developmental/reproductive toxicity, Organ system toxicity (non-reproductive)
  • Panthenol = Alcohol

Benzyl Alcohol

Linked with neurotoxicity.

Bisphenol A (BPA)

BPA disrupts the hormone system and has been linked to breast cancer. So that’s in:

  • Tinned food and drinks…unless they are marked BPA free.
  • Water from plastic bottles… unless they are marked BPA free.
  • Plastic food /drink containers, especially if they are old. They also contain BPA, unless labelled otherwise.
  • …and NEVER put plastic containers in the microwave – tip your food into microwave-safe ceramic or glass containers.

Butylene glycol

Can cause eye irritation

DEA (diethanolamine) and TEA (triethanolamine)

Ethylacrylate and Methyl methacrylate

Cancer, developmental/reproductive toxicity


Midazolidinyl urea, quaternium-15 and imidazolidinyl urea are otherwise known as Formaldehyde.

Oryza sativa (rice) starch



  • Cosmetics, some drinks and foods like jams, pie fillings, beers and pickles that contain Parabens, which disrupt the hormones because they mimick them.
  • They are listed on cosmetics but not on food products, so buy paraben free cosmetics and try to avoid pre-prepared products.

“Parfum”, PVC, Fragrance…

  • Fragranced products like washing powder, air fresheners or cleaning products have PVC added to make them undrinkable so buy fragrance-free.

PEGs (polyethylene glycol)

  • …and anything with “glycol” or “methyl” in the name of it.
  • PEG-10 Dimethicone and laureth-12: Also known as 1,4-Dioxane: Endocrine disruption, identified as a probable human carcinogen by the U.S. Environmental Protection Agency (EPA)

Phenoxyethanol and Potassium hydroxide

Organ system toxicity (non-reproductive), eye irritation

Phthalates (DEHP, BBP, DBP, DMP, DEP), DMDM Hydantoin


Cancer concerns

Propylene Glycol

The FDA says this is safe for general use but can cause cancer and contains toxins that affect reproduction. Errrr…

Sodium Lauryl/Laureth Sulfate (SLS)

This is a frothing agent – so is found in a LOT of things especially shampoos! Can cause skin and eye damage.

Tocopheryl Acetate

There is strong evidence that it is a human skin toxicant, and in-vitro tests on mammalian cells showed positive mutation results, linking it to cancer.


  • It disrupts hormones and has been linked to breast cancer.
  • Found in Anti-bacterial soaps and hand washes.
  • Toothpaste sometimes contains Triclosan so check carefully
  • Gentle castile soap and water is as effective as antibacterial soaps and does not contain Triclosan
