Where does detergent come from?
A very common misconception regarding laundry detergents is that they are soaps. Modern detergents have no soap content at all. They are mostly petrochemicals derived from cru…de oil. Once used in the washing machine, these petrochemicals are flushed into the fresh water supply, and eventually treated at a water treatment plant. Not all of the chemicals are able to be removed from treatment, so some remain in the water supply. Detergents also contain "optical brighteners" which remain imbued in the clothing. These chemicals act as "chemical mirrors" and are meant to reflect more light to make the garment appear cleaner. There is an ongoing debate between petrochemical companies/detergent marketers and environmentalists as to exactly how toxic detergents are to human health and the environment. Not all of the chemicals used in modern detergents are known, as detergent companies are not required by law to list a detail of ingredients. It is difficult for outside parties to ascertain toxicity or lack therof. ( Full Answer )
