Before you wash your hair take a look at the ingredients on the bottle. Although the U.S. Food and Drug Administration requires all manufacturers to list the ingredients on retail products, the label might be difficult to understand because it reads like a vocabulary list from a chemistry book. Many of the ingredients not only help rid the hair of dirt and oils, but they also have harmful side effects.
Diethanolamine(CAS NO.:111-42-2)
Diethanolamine is a chemical that produces the bubbles or lather in shampoo. When inhaled Diethanolamine can irritate the nose and throat, and exposure can irritate skin. Although there is little research regarding the effects of long term exposure to Diethanolamine, in animal studies it has been shown to increase the risk of liver and kidney tumors in mice. In addition, the Cancer Prevention Coalition suggests that Diethanolamine reacts with other chemicals in shampoo to produce a carcinogen called nitrosodiethanolamine, which is linked to stomach, liver, esophageal and bladder cancers.
Formaldehyde and 1,4-Dioxane
A report from the Campaign for Safe Cosmetics reveals that many popular products for babies and children, including shampoo, contain formaldehyde and 1,4-dioxane, both of which are proven to cause cancer in animals. The Environmental Protection Agency lists both of these ingredients as probable cancer-causing agents among humans. Formaldehyde can also cause skin rashes in children.
Preservatives in products gradually release formaldehyde, and 1,4-dioxane results from a processing technique. Because these substances are contaminants, not ingredients, manufacturers are not required to list them on the product labels.
Sodium Lauryl Sulfate
A detergentlike ingredient in shampoos to help remove dirt, sodium lauryl sulfate is not only a skin irritant, but it can damage hair follicles causing thinning or hair loss. SLS is readily absorbed by skin, and in young children it can interfere with eye development. This ingredient is a strong corrosive that also is used in products designed to clean concrete floors and greasy engines.The U.S. Environmental Protective Agency indicates that SLS is used in flea and tick repellent for cats and dogs.
Propylene Glycol
Propylene glycol, an ingredient in industrial antifreeze, may also be an ingredient used in shampoo to prevent it from drying. It has been reported to cause rashes and other skin damage.
Petrolatum
This chemical is known by several other names such as mineral oil jelly, liquid Vaseline and paraffinum. It is one of the main ingredients in baby oil and body lotion. Petrolatum is a chemical that causes photosensitivity. It can cause the extraction of natural oils contained in the skin and bring about chapping and dryness. It is also known to cause premature aging. It is also known to block the removal of harmful chemicals from the skin, thus causing acne and other skin problems

Diethanolamine, often abbreviated as DEA or DEOA, is an organic compound with the formula HN(CH2CH2OH)2. Pure diethanolamine is a white solid at room temperature, but its tendency to absorb water and to supercool mean it is often encountered as a colorless, viscous liquid. It is polyfunctional, being a secondary amine and a diol. Like other organic amines, diethanolamine acts as a weak base. Reflecting the hydrophilic character of the alcohol groups, DEA is soluble in water.
Diethanolamine is a colorless powder or liquid with a slight ammonia-like odor. The odor threshold is 0.27 parts per million (ppm). The chemical formula is C4H11NO2, and the molecular weight is 105.1 g/mol. The vapor pressure is 0.577 mm Hg at 25 degree C, and it has a log octanol/water partition coefficient (log Kow) of -1.46. The CAS NO is 111-42-2.
Diethanolamine is used in cutting oils, soaps, shampoos, cleaners, polishers, cosmetics, and pharmaceuticals. It is also used as an intermediate in the rubber chemicals industry, as a humectant and softening agent, and as an emulsifier and dispersing agent in various agricultural chemicals. Some of the most commonly used diethanolamides include: Cocamide DEA, DEA-Cetyl Phosphate, DEA Oleth-3 Phosphate, Lauramide DEA, Myristamide DEA, Oleamide DEA.
Diethanolamine is used in a number of consumer products, such as shampoos, cosmetics, and pharmaceuticals. Limited information is available on the health effects of this drug. Acute (short-term) inhalation exposure to this drug in humans may result in irritation of the nose and throat, and dermal exposure may irritate the skin.
No information is available on the chronic (long-term), reproductive, developmental, or carcinogenic effects of diethanolamine in humans. Animal studies have reported effects on the liver, kidney, blood, and central nervous system (CNS) from chronic oral exposure to diethanolamine. The National Toxicology Program (NTP) reported an increased incidence of liver and kidney tumors in mice from dermal exposure to this medicine. EPA has not classified diethanolamine for carcinogenicity.
Diethanolamine is a potential skin irritant in workers sensitized by exposure to water-based metalworking fluids. One study showed that DEA inhibits in baby mice the absorption of choline, which is necessary for brain development and maintenance; however, a study in humans determined that dermal treatment for 1 month with a commercially available skin lotion containing DEA resulted in DEA levels that were "far below those concentrations associated with perturbed brain development in the mouse".
In a mouse study of chronic exposure to inhaled Diethanolamine at high concentrations (above 150 mg/m3), it was found to induce body and organ weight changes, clinical and histopathological changes, indicative of mild blood, liver, kidney and testicular systemic toxicity. A 2009 study found that Diethanolamine has potential acute, chronic and subchronic toxicity properties for aquatic species.

Appropriate engineering controls
Handle Diethanolamine in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday.
Personal protective equipment
Eye/face protection
Tightly fitting safety goggles. Faceshield (8-inch minimum). Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).
Skin protection
Handle Diethanolamine(CAS NO.:111-42-2) with gloves. Gloves must be inspected prior to use. Use proper glove removal technique(without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices.Wash and dry hands.
The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.
