Formaldehyde Releasing Preservatives
According to the EPA formaldehyde is a probable carcinogen and can be absorbed through the skin, though the risk of cancer from skin contact is not fully understood. Formaldehyde can also trigger skin reactions in people who are sensitive to the chemical. Contact dermatitis specialists recommend that children avoid exposure to products containing formaldehyde. Formaldehyde contaminates personal care products when common preservatives, such as Quaternium-15 release formaldehyde over time in the container.
NOTE: Shampoo's, Body Washes, Bubble Baths, Lotions, Hair Relaxers, Liquid Hand Soaps and even some Baby Wipes will not state they contain formaldehyde releasing preservatives. Formaldehyde releasing preservative you should look for include: DMDM Hydantoin, Quaternium-15, Diazolidinyl urea, Imidazolidinyl urea, and Sodium hydroxymethylglycinate. Please also note this list does not contain every formaldehyde relesing preservative.
1,4-dioxane
According to a 1998 memorandum from a California State haelth official, 1,4-dioxane is readily absorbed through the lungs, skin and gastrointestinal tract of mammals. The federal Consumer Product Safety Commission reports that "the presence of 1,4-dioxane, even as a trace contaminat, is a cause for concern. However, the FDA has not established or recommended a "safe" level of 1,4-dioxane in cosmetics. The Environmental Protection Agency classifies 1,4 dioxane as a "probable human carcinogen". The U.S. department of health and Human services, National Toxicology Program, lists 1,4 dioxane as "reasonably anticipated to be a human carcinogen." According to the International Agency foor Research on Cancer, an initiative of the World Health Organization, 1,4-dioxane is "possiblycarcinogenic to humans." The State of California's Environmental Protection Agency lists 1,4-dioxane on its publicly mandated annual list of chemicals known to cause cancer or reproductive toxicity. According to the New Jersey Department of Health and Senior Services, 1,4dioxane "should be handled as a carcinogen-with extreme caution."
NOTE: Shampoo's, Body Washes, Bubble Baths, Lotions, Hair Relaxers, Liquid Hand Soaps and even some Baby Wipes will not state they contain 1,4-dioxane. Ingredients in the list of product ingredients likely to be contaminated with 1,4-dioxane can be any of these chemicals: Ceteareth-6, Ceteareth-12, Ceteareth-20, PEG-8, PEG-12, PEG-100 stearate, PEG-150 stearate, Laureth-23, PEG-80 sorbitan laurate, Sodium Laureth Sulfate, PEG-7 esters, Laureth-4, PEG-14M, PEG-3 glyceryl cocoate, PEG-120 methyl glucose dioleate, PEG-45M, PEG-150 distearate, PEG-45 palm kernal glycerides, PEG 150 pentaerythrityl tetresetearate, Sodium laureth-13 carboxylate, PEG-40 glyceryl cocoate, PEG-7 glyceryl cocoate, Disodium PEG-4 cocamido mipa-sulfosuccinate, Potassium laureth phosphate, PEG-50 shea butter, PEG-75 lanolin, BIS-PEG/PPG-16/16 PEG/PPG-16/16 dimethicone, PEG-40 hydrogenated castor oil,Sodium laureth-8 sulfate, Magnesium Laureth-8 sulfate, Sodium oleth sulfate, magnesium oleth sulfate, PEG-75 lanolin, Oleth-20, Dimethicone PEG-7 cocoate, PEG-12 dimthicone, PPG-5-ceteth-10 phosphate, Oleth-3 phosphate, Cetyl PEG/PPG-10/1 dimethicone.
Sodium Lauryl Sulfate (SLS) & Sodium Laureth Sulfate (SLES)
Used as detergents and surfactants, these closely related compounds are found in car wash soaps, garage floor cleaners and engine degreasers. Yet both SLS and SLES are used more widely as one of the major ingredients in cosmetics, toothpaste, hair conditioner and about 90% of all shampoos, body washes, liquid handsoaps, dish detergent, laundry detergent and products that foam.
According to the American College of Toxicology states both SLS and SLES can cause malformation in children's eyes. Other research has indicated SLS may be damaging to the immune system, especially within the skin. Skin layers may separate and inflame due to its protein denaturing properties. It is possibly the most dangerous of all ingredients in personal care products. Research has shown that SLS when combined with other chemicals can be transformed into nitrosamines, a potent class of carcinogens, which causes the body to absorb nitrates at higher levels that eating nitrate-contaminated food." According to the American College of Toxicity report, "SLS stays in the body for up to five days..." Other studies have indicated that SLS easily penetrates through the skin and enters and maintains residual levels in the heart, the liver, the lungs and the brain.
SLS is absorbed into your body from skin applications, from that shower in the morning and those warm comforting relaxing baths in the evening. One of the effects of sodium lauryl sulfate is that it mimic's the activity of the hormone estrogen. This can have many health implications, plus be responsible for a variety of health problems such Menopausal symptoms, PMS, right down to dropping male fertility and increasing female cancers such as breast cancer, where estrogen levels are known to be involved.

Note: The use of sodium laureth sulfate in childrens products is particularily worrying. It is known that, whether it gets in the eyes or not, skin application DOES lead to measurable concentrations in the eyes of children. This is known to affect eye development, & the damaged caused is irreversible. Learn More
Shampoos are among the most frequently reported products to the FDA. Reports include eye irritation, scalp irritation, tangled hair, swelling of the hands, face and arms and split and fuzzy hair. This is highly characteristic of sodium laureth sulfate and almost definitely directly related to its use.
The Environmental Canada Domestic Substance List classifies SLES as a high human health priority. SLES is listed as a possible carcinogen and as expected to be toxic or harmful to humans.
Sodium Dodecylbenzene Sulfonate (sodium dodecylbenzenesulfoante)
The New Jersey Department of Health and Senior Services Hazardous Sunstance Fact Sheet contains the following information: Sodium Dodecylbenzene Sulfoante is a white to light yellow sand-like solid. It is used as a detergent, incleaning products, and in pesticides. Sodium Dodecylbenzene Sulfoante is on the Hazardous Substance List because it is cited by DOT and the EPA. Under the heading Hazard Summary it states: Sodium Dodecylbenzene Sulfoante can effect you when breathed in. Contact can irritate the skin and eyes with possible eye damage. Breathing Sodium Dodecylbenzene Sulfoante can irritate the nose, throat and lungs causing coughing, wheezing and/or shortness of breath. Under the heading Acute Health Effects it states: The following acute (short-term) health effects may occur immediately or shortly after exposure to Sodium Dodecylbenzene Sulfoante. Read the report
Cocoamidylpropylbetaine (Cocoamidylpropyl Betaine)
The American Contact Dermatitis Society named Cocoamidylpropyl Betaine Allergen of the Year in 2004. It is used in surface cleaners, dishwashing detergents, powder and liquid laundry detergents and toilet cleaners. It is known to cause irritation of the skin, eyes and lungs.
Sodium Alkylbenzenesulfonate (sodium alkylbenzene sulfonate)
Alkylbenzene sulfonates are comprised of three active ingredients sodium dodecylbenzene sulfonate, dodecylbenzene sulfonic acid and alkylbenzene sulfonic acid. Alkylbenzene sulfonates are antimicrobial pesticides that are largely used as contact sanitizers in food processing plants.
2,6-Di-t-butyl-p-cresol (BHT) (commonly known as Butylated Hydroxytoluene BHT)
Butylated Hydroxytoluene (BHT) is a synthetic additive that contains toluene. Toluene is a poison. According to the material Safety Data Sheet (MSDS), toluene can cause respiratory problems, dizziness, and in high concentrations-death. Toluene is a skin and lung irritant.
Lauramide DEA and TEA-Cocoyl Glutamate
Amine Family: This chemical family includes Diethanolamine (DEA), triethanolamine (TEA) and monoethanolamine (MEA). Hormone-disrupting chemicals that can form cancer-causing nitrates,
- Restricted in Europe due to carcinogenic effects, yet are still used in the US
- Americans may be exposed 10-20 times per day with shampoos, shaving creams and bubble baths
On the show "CBS This Morning" Dr. Samuel Epstein,Professor of Environmental Health at the University of Illinois said "Repeated skin applications of DEA-based detergents resulted in a major increase in the incidence of two cancers-liver and kidney cancers. John Bailey, head of the cosmetics division of the FDA, says that the new study is especially important since "the risk is significantly increased for children."
Studies also show that DEAs (including cocamide DEA) directly inhibits fetal brain development in laboratory studies by blocking the absorption of choline, a nutrient required for brain development and maintenance
Information from the Cancer Prevention Coalition states:
DEA is diethanolamine, a chemical that is used as a wetting agent in shampoos, lotions, creams and other cosmetics. DEA is used widely because it provides a rich lather in shampoos and keeps a favorable consistency in lotions and creams. DEA by itself is not harmful but while sitting on the stores shelves or in your cabinet at home, DEA can react with other ingredients in the cosmetic formula to form an extremely potent carcinogen called nitrosodiethanolamine (NDEA). NDEA is readily absorbed through the skin and has been linked with stomach, esophagus, liver, and bladder cancers.
According to the International Agency for Research on Cancer (IARC), "There is sufficient evidence of a carcinogenic effect of N-nitrosodiethanolamine -- ." (1) IARC recommends that NDEA should be treated as if it were a carcinogen in humans.
Lauramide DEA is listed as a cosmetic ingredient contaminated with DEA.
Even small amounts of this potent carcinogen can increase the risk of cancer.
Propylene Glycol (Antifreeze)
A cosmetic form of mineral oil found in automatic brake and hydraulic fluid and industrial antifreeze. In the skin and hair, propylene glycol works as a humescent, which causes retention of moisture content of skin or cosmetic products by preventing the escape of moisture or water. The Material Safety Data Sheet warns users to avoid skin contact with propylene glycol as this strong skin irritant can cause liver abnormalities and kidney damage.

Methylparaben
Methylparaben is widely used as a preservative in women's cosmetics, such as skin creams and deodorants. One of the physical dangers associated with methylparaben is its connection with tumors in the breast. A report in the January-February 2004 issue of the Journal of Applied Toxicology states that when several breast tumors were examined by researchers, high levels of methylparaben were found in the tissues.
The October 3, 2006, issue of Toxicology published a study that shows when skin treated with creams that contain methylparaben was exposed to the sun's UVB rays, the skin cells died and there was considerable oxidative stress on the skin's tissue. Oxidative stress, according to the National Institute of Standards and Technology, is responsible for a number of disease processes, including cancer.
Parabens, including methylparaben, have estrogenic affects on the body, which means they can affect the reproductive glands. The January 2009 issue of Reproductive Toxicology reports that there is a probable interaction between parabens and the health and activity of cells in the testes, meaning a possible decrease in sperm production in males.

Polyquaternium-10.tetrasodium EDTA
Followed by any number, film forming impression of softness, they are carcinogenic, mutagenic, toxic and cause adverse reactions. Induced contact dermatitis, causes fatal drug allergy (anaphylactic shock), may cause increased sensitivity to muscle relaxants. They are a formaldehyde releaser, thus a potential carcinogen. It may be contaminated with acrylamide, a central nervous system toxin.
Methylchloroisothiazolinone
In pregnant women prolonged exposure to this ingredient in shampoos may cause abnormal brain development in the fetus. This chemical, also known as MIT, attacks the nervous system, which means that exposure to the chemical, over a period of time may be a factor in developing Alzheimer's disease and other disorders. MIT also contributes to cancer and liver problems. Source: http://www.helium.com/items/823471-how-dangerous-are-the-chemicals-in-your-shampoo
