Hidden Chemicals: DEA

Soap Suds May Not Be As Clean As They Seem

DEA (diethanolamine) and DEA compounds are used to give cosmetics a creamy or sudsy texture. DEA is also used as an emulsifier in shampoos, cleaners and detergents.

FOUND IN:

  • moisturizer
  • sunscreen
  • soap
  • shampoo
  • hair conditioner
  • shaving cream
  • mascara
  • eyeliner
  • eyeshadow
  • blush
  • make-up foundation

WHAT TO LOOK FOR:

Triethanolamine, diethanolamine, DEA, TEA, cocaminde DEA, cocamide MEA, linoleamide MEA, myristaminde DEA, oleamide DEA, stearamide DEA, Tea-lauryl sulfate

RISKS

Skin Irritation: DEA and its compounds have been found to cause mild skin and eye irritation (1).

Cancer: exposure to high doses of DEA and its compounds have been shown to cause liver cancer (2)(3)(4).

Organ System Toxicity: Studies have found that DEO affects human male reproductive health by altering sperm structure, and causing abnormalities that affect the sperms ability to swim and complete fertilization (5).
