How do soaps get things clean?

What environmental issues are involved
with detergents containing phosphates?

Is there a difference between
"soap" and "detergent"?
Soap is an excellent cleanser because of its ability to act as an emulsifying agent.

As explained before, soap contains oil, mainly.

These drops of oil are suspended in the water. This is how soap cleans your hands.

Released into the flow of waste water coming from the home, these detergents can have far-reaching environmental impacts:

they can have poisonous effects in all types of aquatic life if they are present in sufficient quantities, and this includes the biodegradable detergents.


soaps are manufactured from natural materials and form scum when use in hard water while detergents are manufactured from synthetic materials and do not form scum in hard water.
