Who responsible to washing out of the dirty clothes?

Clean clothes hanging outside the garden in the morning everyday~

Whose resposible for these actually?

Peaple oftenly called it as luandry detergents, and what is the actual name of it in the sense of chemistry? Dirty cloths, they need soaking in a solution containing alkylbenzene sulfonate, phosphates silicates, perborates, etc...*blablabla...*

Wow~ what a long chain of chemicals name?? These chemicals that have taken the hard work out of washing once a household chore that was tackled everyday.

*taadaa~~~dirty cloths?? FAB helps it~(LOL)

To understand what is needed to achieve effective cleaning, it is helpful to have a basic knowledge of detergent in chemistry.

Synthetic detergents function in the same way as soaps. They have a long non-polar hydrocarbon chain and a polar group at the end. The polar groups of most synthetic detergents are sodium sulfates or sodium sulfonates. They have an advantage over soaps in cleaning process which are active in hard water. Yet, they are not equal of soap in cleaning power and they must be combined with additives.

They have an advantage over soaps in that they are not precipitated by some metal ions which are present in hard water. the negatively changed soap micelles are neutralized by these ions to form a scum. For example of scum are (RCOO-)2Ca2+ and (RCOO-)2Mg2+ . Laundry detergents clean clothes by capturing hydrophobic dirt inside micelles. Dirt is thus solubilised and then removed from the clothes by water.

Laundry detergents is a surfactant which can make up 10-20%. A surfactant is a substance that can greatly reduce the surface tension of water when used in low concentrations. It can be classified by the presence of formally charged groups in its head. A nonionic surfactant has no charge groups in its head. The head of an ionic surfactant carries a net charge. If the charge is negative, the surfactant is more specifically called anionic; if the charge is positive, it is called cationic. Detergents are built around "surface active" reagents or "surfactants" for short.

Consequencely, some of them are not biodegradable that largely impact on environment. As reseach shown, The carbon dioxide emission from a liquid laundry detergent used to wash an average load of laundry is about 0.7 kilograms (1.5 pounds). The loss of natural habitat potential from a liquid laundry detergent used to wash an average load of laundry is about 0.5 square metres (5.8 square feet) based on primary production correlations.
