please i need some scientefic information about surfactants?

Surfactants are agents such as a detergent or a drug that reduces the surface tension of liquids so that the liquid spreads out, rather than collecting in droplets.\n\nIn physiology,  they are surface-active lipoprotein substances secreted naturally in the lungs, lack of which causes respiratory problems especially in premature babies

I'll go out on a limb and suppose that you need some very simple projects that can demonstrate polymer properties to the layperson.\n\nPhysics:  \n\nIf you take a rubber band, an elastomer, suspend a weight from it, and gently heat the rubber band with something like a hair drier, you can demonstrate that polymer chains prefer to adopt a random coil configuration rather than a straight, linear configuration. (I'll leave out the basic thermodynamic details so you can delve deeper into the subject.)\n\n\nChemistry:\n\nTo demonstrate the differences in size between polymers and small molecules, look up the size of a single water molecule and then get a piece of foam rubber.  The water molecule's size is on the order of Angstroms, while the foam rubber is essentially one gigantic molecule.\n\nIf you have access to sebacoyl chloride and hexamethylene diamine, you can make Nylon-6 by using equal parts of both reactants.  The polymer forms at the interface of the two liquids, and you can use tweezers to pull the polymer out of the reaction vessel.  NOTE:  Proper safety precautions MUST be followed as both chemicals are irritants. \n\nI've left out sources and a lot of other details so you can research the physics/chemistry of the examples given here.

Try searches at the following. You may need to hit the library.   Your answer will probably not be found on the web.\n\nhttp://www.scirus.com/srsapp/\n\nhttp://www.scienceresearch.com/search/

Soaps are water-soluble sodium or potassium salts of fatty acids.Saponification of fats and oils is the most widely used soapmaking process.\nDetergent surfactants are made from a variety of petrochemicals (derived from petroleum) and/or oleochemicals (derived from fats and oils). \n\nCheck these links to find more information On Soaps & detergents to help your chemistry Project.

1.Call Pragmatics,Inc. at 574-295-7908,ask about kit containing 25 different surfactants\n\n2. Do Boolean search on patents using terms surfactant and electrochemistry. Roche has several patents in this area

try this site.  if you ever need to look up other chemicals, etc. search for msds b/c that is where all the info on storage, etc will be.\n\nhttp://www.chem.tamu.edu/class/majors/msdsfiles/msdsleadsulfate.htm

Chemexper.com its super cool , type in the name of the compound and it will give you a ton of info about the thing you are looking at. I order chemicals off of it but it was really useful in researching for my Ochem labs as well.
