What is bar soap made out of?
98561
The manufacture of soap is based on a chemical reaction (saponification) in which an alkali acts upon a fat to form a metal salt (soap) and an alcohol (glycerol).\n\nYou can get more information in the link below.

soap (long alkyl chains with carboxylate salts at the end)\n\nwater\n\nIf the sink has any rubber components, rubber is a polymer of carbon-carbon (as well as other) bonds.

its a wax:\nWaxes have a fatty acid bonded to a longchain alcohol by the oxygen and is a two part chain with a double bonded o to the fatty acid\n\nFats have a glycerol backbone with three fatty acid chains attached which is clearly not this one\n\nOils are same as fats in that they have glycerol backbone and serves like fat in the sense that fat:animals::oil:plants\n\nSoap... idk whats up with that answer but i know that old time soap was made from some sort of fat and now they are process differently with different material. no matter what, it does not have the right chemical make up

I'm quite sure that it does since bar soap has touched your body. It also probably collects bacteria from the air. Actually, pretty much everything has bacteria on it.

its just liquid soap that is scented

A soap is a surface active agent, which  means it attaches to the surface of a substance or slightly alters the surface energy of the substance.  When two materials are brought into contact suchs as two liquids or a solid and a liquid, or two solids, the differences in the surface energies will determine whether the are immiscible or , in the case of solids, one wets the surface of another or simply beads up on it.  \n\nThe best "soap" needs to be chosen based on what the liquid chemistry is.  For example, if you want to mix a material in water or alcohol or oil.  Each could require a different "soap" to be used.

i'm guessing, its dried soap.. or your skin is really dry..

Look   lather  up  soap  thats good  too. BESIDES  some of the soaps  out  there on the market  smell  sooooooo  good. Makes me want to  kiss  a man.

None.....soap scum is a chemical reaction.\n\nMold is the most common thing you find in the shower.\n\nBleach will destroy both of these.

The ethanol or alcohol is less polar that water and the fat that is being hydolyzed from its parent triglycerides is not soluble in water to any great degree. This is true if you are discussing the determination of free fatty acids in a fat or an oil. If you simply wish to make soap from fat, the base, water and fat will do a nice job of it but it will require additional sodium ion, usually in the form of salt to curdle the soap base.\n\nI learned to make soap for washing purposes with a recipe that started with: "First one must select a nice fat pig to kill...."

Soap is the sodium - Na - salt of a fatty acid, that is a salt obtained when a high carboxylic acid like palmitic acid etc. reacts with NaOH(caustic soda)&#92; or sodium hydroxide)\n\nIts chemical formula in its general form is R-COO-Na\nwhere R is an alkyl group of the form C(n)H(2n+1)-\n\nfor eg.- C(17)-H(33)-COO-Na\n\nwhere the H atom of the acid is replaced by the Na atom in a process called Saponification or salting of soap

i went to a diabetes class a few weeks ago and the wound care specialist that taught our class says the best kind of soaps you can use are the ones like dove and ivory because they have moisterizers in them to keep you skin moisterized and not to use the ones that are deorderant soaps cause they dry ur skin out

Many soaps are mixtures of sodium or potassium salts of fatty acids which can be derived from oils or fats by reacting them with an alkali (such as sodium or potassium hydroxide) at 80°–100 °C in a process known as saponification. The fats are hydrolyzed by the base, yielding glycerol and crude soap. Historically, the alkali used was potash made from the deliberate burning of vegetation such as bracken, or from wood ashes.\n\nSoap is derived from either oils or fats. Sodium Tallowate, a common ingredient in many soaps, is in fact derived from rendered animal fat. Soap that is made of vegetable oils, such as olive oil, are generally termed castile soap.\n\nSO yes, some soap is, some soap isnt

I'll answer the last part of your question first. Soap is made up of polar molecules. That just means that one end of each molecule is different from the other like the poles of a magnet. One end dissolves in grease and fats while the other end dissolves in water. Since most really dirty things are fatty and greasy, this means that one end of each soap molecule sticks to the dirt on your hands while the other end sticks to the water running over them. This washes the dirt away. Why not use plain water? If you don't have soap plain water will help get you clean but because of surface tension water won't stick to grease so you will never get completely clean. Another class of cleaners solves this problem. Detergents reduce the surface tension of water allowing it to clean better. Look at the list of ingredients on your cleanser. If one of them is Sodium Lauryl Sulfate, your cleanser is a detergent. Now for the first part of your question. Long ago people found that you could make a cleaner by heating lard (renderings from animals killed for food) with potash, an alkali produced by burning wood, probably for cooking the aforementioned food. This discovery was probably accidental, the result of being in the right place at the right time. It took place so long ago that the discoverer (or discoverers, it probably happened in several places at different times) is lost in history. BTW. It's no coincidence that many of today's soap producers are owned by or connected to slaughter houses and meat producers. Do some research on Procter and Gamble. Your teacher will be proud of you.

This website has a very nice description of how to make homemade soap\n\nhttp://www.teachsoap.com/soapmakingmethods.html

The first soap was made from animal fat and ashes.  People may have even been aware of this combination before history was recorded, but there is no way of knowing for sure.  This is what I found at the website I've listed in sources:\n\n"It is recorded that the Babylonians were making soap around 2800 B.C. and that it was known to the Phoenicians around 600 B.C. These early references to soap and soap making were for the use of soap in the cleaning of textile fibers such as wool and cotton in preparation for weaving into cloth."

Hi there,\n\nSoap is able to remove oil from our skin because while you've rightly pointed out soap is made from oil, its chemical and molecular structure consists of 2 main parts that are attracted to oily substances (known as the hydrophobic part) and a part that is attracted to water-based or aqueous substances (known as the hydrophilic part). Because of this property, soap can break up the oil on our skin and bind it to the water- Allowing us to remove the oil from our skin.  As an aside, you should know that normally Water and Oil dont mix at all- If you add some some liquid soap to a mixture of water and oil you will notice that the oil and water will mix togther!! This is how the soap works to remove the oil from our skin by allowing the water you apply during a shower to mix and "wash" away the oil+soap mixture from our skin.  I hope that answers your question :-)
