give the chemical of soap?

Chemically, soaps are metallic salts of fatty acids. 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). A number of methods may be employed to make soap, but all are based on the same principle of operation. Fats and oils (often blended) are heated in a large vessel, then enough alkali to react with all the fat is stirred in. Salt is added, and the soap then forms a light curd that floats to the surface. Glycerol, a valuable byproduct, can be distilled from the liquid residue.\n\nTo produce a purer soap, the curds are washed with salt solution, water is later added, and the solution is allowed to settle; the upper of the two layers thus formed is the pure soap, called settled soap. It is thoroughly churned, poured into huge frames, cut with wires, shaped, and stamped. Hard-milled soap is run over chilled rollers and is scraped off as chips which are rolled into ribbons, cut, and shaped. Soap is marketed also as chips, flakes, and beads and in powdered form. Soap powders, as distinguished from powdered soap, contain builders that assist in rough cleaning. Soaps differ according to the lathering properties of the fat or oils and according to the alkali employed. When sodium hydroxide is used as the alkali, hard soaps are formed; potassium hydroxide yields soft soaps.\n\nAluminum, calcium, magnesium, lead, or other metals are used in place of sodium or potassium for soaps used in industry as paint driers, ointments, and lubricating greases and in waterproofing. Fillers are added to many soaps to increase lathering, cleansing, and water-softening properties; the sodium salt of rosin is commonly used in yellow laundry soap to increase lathering. Soap substitutes include saponin-containing plants such as soapwort and shagbark and the modern soapless detergents (usually sulfonated alcohols), which may be used in hard water and even in saltwater without forming curds.

Commercially made bar soaps are formulated to mitigate all of these disadvantages:\n\nA wide variety of emollient materials, such as shea or cocoa butters, are substantive to the skin. \nPoorly finished soaps contain alkali (NaOH) and react mildly basically with skin and fabric; commercial products are finished to neutrality or to a weak acid content to prevent this and be more compatible with the skin's slightly acidic pH. \nCommercial products use chelating molecules (sequestrants), often EDTA derivatives to bind with any free Ca or Mg ions and prevent soap scum. These also help reduce fragrance loss, discolouration and rancidity.

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

Total Fatty Matter\n\nIf the soap base is not refined, white colored soap noodles cannot be manufactured. These will be little off white in color. White soap noodles are preferred because any light colored soap can be made. For toilet soap, generally 78% TFM( total fatty matter) noodles are used. As TFM value decreases, soap quality decreases.

I'm sure you mean, "What is the difference between a detergent and a soap?"\n\nA detergent is a general term that can mean any non-water solvent that one uses to clean. A soap is technically a specific kind of chemical compound that is usually the potassium or sodium salt of a fatty acid (can be an organic derivative, or can be synthesized). \n\nSoaps are kinds of detergents, but not all detergents are soaps.

It depends on the salt. A salt of calcium, magnesium, or iron will form an insoluble compound that will precipitate with a soap molecule that is known as soap scum.\n\nHere is a typical reaction:\nCa2+(aq)  + 2C17H35COO-(aq)  ==> (C17H35COO-)2Ca2+(s)\n\nSodium chloride will not form a precipitate with soap as long as the soap is a carboxylate.\nhttp://dl.clackamas.cc.or.us/ch106-04/structur1.htm

Soap is a surfactant cleaning compound used for personal or minor cleaning. It usually comes in solid moulded form, termed bars. In somewhat recent years, the use of thick liquid soap has become increasingly widespread, especially from dispensers in public washrooms. Soap is used in conjunction with water for washing and cleaning. The wet soap residue and the dirt or soil are rinsed off with clean water afterwards. In the developed world, synthetic detergents have superseded soap as a laundry aid.\n\nMany 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.

To saponify with lye and water produces soap, with the glycerin still in it.\n\nTo saponify with lye water and ethanol produces pure glycerin, water and biodiesel fuel.

Most hand sanitizers use alcohol as a sterilant, so unless there's something in them to make them more alkaline, the pH should be pretty close to neutral -- 7.  That would mean that soaps have the higher pH.

SOAP is a protocol, Simple Object Access Protocol, SOAP uses HTTP as a transport layer, you can use soap with other protocols. Right now, is used to instance web services (an application as a service). The idea with SOAP is to access an object methods remotly. You can download the SOAP specifications in www.w3.org/TR/soap/

Another one for wikipedia.com:\n\n"Many soaps are mixtures of sodium (soda) or potassium (potash) 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.

Sodium Tallowate, a common ingredient in many soaps, is in fact derived from rendered beef fat. Soap can also be made of vegetable oils, such as olive oil. Soap made entirely from such oils, or nearly so, is called castile soap. The use of the word "soap" has become such a household name that even cleaning solutions for the body that don't have soap in the ingredients are referred to as soap."\n\nThere you have it: fats or oils.
