Our daily exposure to chemicals leave us vulnerable to breakdowns of our immune systems. Below is a list from the Green Guide of the “dirty dozen” to avoid. Read your labels carefully:
1. Antibacterials
Triclosan, widely used in soaps, toothpastes and deodorants, has been detected in breast milk, and one recent study found that it interferes with testosterone activity in cells.
2. Coal Tar
Coal tar is a known human carcinogen used as an active ingredient in dandruff shampoos and anti-itch creams. Coal-tar-based dyes such as FD&C Blue 1, used in toothpastes, and FD&C Green 3, used in mouthwash, have been found to be carcinogenic in animal studies when injected under skin.
3. Diethanolamine (DEA)
DEA is a possible hormone disruptor, has shown limited evidence of carcinogenicity and depletes the body of choline needed for fetal brain development. DEA can also show up as a contaminant in products containing related chemicals, such as cocamide DEA.
4. 1,4-Dioxane
1,4-Dioxane is a known animal carcinogen and a possible human carcinogen that can appear as a contaminant in products containing sodium laureth sulfate and ingredients that include the terms “PEG,” “-xynol,” “ceteareth,” “oleth” and most other ethoxylated “eth” ingredients.
5. Formaldehyde
Formaldehyde has a long list of adverse health effects, including immune-system toxicity, respiratory irritation and cancer in humans.
6. Fragrance
The catchall term “fragrance” may mask phthalates, which act as endocrine disruptors and may cause obesity and reproductive and developmental harm. Avoid phthalates by selecting essential-oil fragrances instead.
7. Lead and Mercury
Neurotoxic lead may appear in products as a naturally occurring contaminant of hydrated silica, one of the ingredients in toothpaste, and lead acetate is found in some brands of men’s hair dye. Brain-damaging mercury, found in the preservative thimerosol, is used in some mascaras.
8. Nanoparticles
Tiny nanoparticles, which may penetrate the skin and damage brain cells, are appearing in an increasing number of cosmetics and sunscreens. Most problematic are zinc oxide and titanium dioxide nanoparticles, used in sunscreens to make them transparent.
9. Parabens
(methyl-, ethyl-, propyl-, butyl-, isobutyl-) Parabens, which have weak estrogenic effects, are common preservatives that appear in a wide array of toiletries.
10. Petroleum Distillates
Possible human carcinogens, petroleum distillates are prohibited or restricted for use in cosmetics in the E.U. but are found in several U.S. brands of mascara, foot-odor powder and other products. Look out for the terms “petroleum” or “liquid paraffin.”
11. P-Phenylenediamine
Commonly found in hair dyes, this chemical can damage the nervous system, cause lung irritation and cause severe allergic reactions. It’s also listed as 1,4-Benzenediamine; p-Phenyldiamine and 4-Phenylenediamine.
12. Hydroquinone
Found in skin lighteners and facial moisturizers, hydroquinone is neurotoxic and allergenic, and there’s limited evidence that it may cause cancer in lab animals.
