Do you know the ingredients of shampoo

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
