What differences have been observed between the biodegradability of soaps and Syndets?

The principal differences between soaps and detergents are that the hydrophobic, organic (nonpolar) portion of a soap is usually a more simple organic compound than that of a typical detergent; also, the hydrophilic (ionizable) portion of a typical detergent is characteristically the salt of a strong acid (sodium …

What problems have been caused by synthetic detergents?

These optical brighteners possibly cause reproductive and developmental problems. Synthetic ingredients in optical brighteners can cause skin sensitivity and allergic reactions as well.

What is the impact of synthetic detergent on environment pollution?

Broadly, synthetic detergents are known to be corrosive, toxic, slow to biodegrade and contribute to the growing levels of eutrophication in waterbodies. The major debate surrounding detergents is linked to the use of phosphates as builders.

What are the uses of synthetic detergent?

Synthetic detergents are used for a variety of applications, such as: Washing clothes. Fuel additives to prevent fouling. Biological reagents.

Is there such a thing as a soapless detergent?

Soaps have been used for washing for thousandsof years but they always had one disadvantage. Ifused in hard water, i.e. water containing dissolved 2+ 2+minerals such as Ca or Mg , they produced an insoluble scum.Soapless detergents have similar structures to soapsbut are manufactured from aromatic hydrocarbonsobtained from crude oil.

How are biodegradable detergents bad for the environment?

Biodegradable detergents cause problems if they enter our stormwater systems, streams, rivers and ultimately the ocean. No matter which detergent you use, always direct your wastewater to the sewer or use it to irrigate your garden (without allowing any runoff).

How to draw the formula of a soapless detergent?

State the meaning of saponification and explainwhat advantage it has over ordinary hydrolysis os anester.4. Draw the structural formula of a typical soaplessdetergent molecule.5.

Why are soap less detergents good for hard water?

These are derived from fats and oils, petroleum and benzene in solution, these detergents form liquids of varying degrees of alkanet. All soap less detergents have the advantages of not reacting with the water hardness, so they wash equally well in soft and hard water.
