Here is what Deidre Imus says about some of these ingredients in her book, The Essential Green You:
Sodium Lauryl Sulfate- Research suggests, skin irritant, carcinogenic, neurotoxic, developmentally toxic effects. It may also release a carcinogen known as 1,4-dioxane. Found in shampoos, conditioners, bar soaps, body washes, facial cleansers, liquid hand soaps, acne treatments, hair dyes, mascara, shaving products etc....
Fragrance- The FDA lets personal care companies classify their fragrance formulas as "trade secrets". Most fragrances contain highly volatile allergens that are a recognized cause of asthma and skin rashes in children and adults. Many contain dibutyl phthalates which have been identified as potential hormone disruptors in animal studies.
Cocamide DEA- The National Library of Medicine has found moderate evidence that DEA is toxic to the human immune system and irritating to skin, while the EPA classifies it as a "known human respiratory toxicant". Once your skin absorbs it, DEA is also prone to forming compounds called nitrosmaines, which have been shown to cause cancer in lab animals.
