This is a general name for a group of synthetic surfactants. They are slow to biodegrade in the environment and have been implicated in chronic health problems. Researchers detergent manufacturing plant in England have found that in trace amounts they activate estrogen receptors in cells, which in turn alters the activity of certain genes. For example, in experiments they have been found to stimulate the growth of breast cancer cells and feminize male fish. One member of this family of chemicals is used as a common spermicide, indicating the general level of high biological toxicity associated with these compounds.

Artificial fragrances

Artificial fragrances are made from petroleum. Many do not degrade in the environment, and may have toxic effects on both fish and mammals. Additionally, they often can cause allergies and skin or eye irritation.

Diethanolamines (also diethanolamine, triethanolamine and monoethanolamine).

A synthetic family of surfactants, this group of compounds is used to neutralize acids in products to make them non-irritating. Diathanolamines are slow to biodegrade and they react with natural nitrogen oxides and sodium nitrite pollutants in the atmosphere to form nitrosamines, a family of
