What is the scientific  technical difference between a soap, a shampoo, and a detergent?
952403
Detergent is a compound, or a mixture of compounds, intended to assist cleaning. Any thing then that is used for cleaning, can be called detergent. For example, if plain water is used for cleaning, it is a detergent - technically. \n\nHence, soap and shampoo are under the term detergents since they are used for washing and cleaning. Specifically, they both contain surfactants that clean by stripping oil and dirt from our skin, clothing, and/or hair. The difference between the two, however, is that surfactants in shampoo are milder than the one in soap. Soap bonds to oils with such affinity that it removes too much if used on hair. Shampoo uses a different class of surfactants balanced to avoid removing too much oil from the hair.

All soaps and detergents are they way they are because they're amphoteric substances. That means one end of the molecule is a fatty chain that repels water but loves nonpolar chemicals. the other end of the detergent molecule is polar and probably carries a charge. This side likes water.\n\nSo what happens is the fatty chain clings to greasy things and the polar or charged end clings to water. This brings your greasy stains closer to the water in your wash and off of your clothing.

I don't know where you got the idea that soap and shampoo are acidic. That is not true in very many cases. \n\nSoap is made from a saponified fat by reacting a fat with an alkali. When using soap it reacts with dissolved calcium carbonate in water to form a precipitate called soap scum. If you use it in your hair this insoluble deposit will end up on your hair. Soap will also remove more oil from hair than shampoo will, leaving hair dry and brittle. \n\nShampoo is similar, but often has much more gentle properties than soap. It generally contains an anionic surfactant, but commonly in baby shampoos will have an amphoteric surfactant to reduce irritation. The primary difference is that due to a slightly different molecular structure, shampoo is less likely to remove all oil from your hair than soap, and less likely to leave insoluble deposits behind like soap. \n\nVery little soap or shampoo has a pH of 6. Shampoo often has citric acid added to reduce its pH because naturally it is  basic- not acid, as is most soap. To give you some examples of the pH of soap, Zest has a pH of 10, Ivory has a pH of 9.5, and Dove has a pH of 7. (This is one reason I make my own soap.)\n\nBy the way, all those vitamins would do you more good if you ate them. Hair is dead.

Soaps generally are only used to lubricate your hands (or other areas) to allow bacteria to 'slide' off. People think soaps act as an antibacterial but they are wrong. It is simply the lubricating affect of them that makes them useful. This also means that it doesn't matter whether you use hot or cold water either. Bacteria is not killed any better with hot water than it is with cold.

The surface of a strand of hair is covered with overlapping sheets, somewhat like the scales on a fish, or the shingles on a house. This surface is called the cuticle.\n\nAlkaline solutions raise these scales, so they stand up. This makes the hair rougher, makes it look dull, and makes the hair shafts stick together due to the rough texture.\n\nMost shampoos are made slightly acidic, to keep the cuticle smooth and lying flat on the hair shaft. Ingredients like citric acid are added to acidify the shampoo.\n\nAs the shampoo mixes with the water in the shower or bath, or mixes with dirt on the hair, it can become less acidic as the acids mix with alkaline water or dirt. A compound that releases more acidifying ions when the acidity gets low, or absorbs acid when the acidity gets too high, is called a buffer.\n\nA typical buffering agent used in shampoo is sodium citrate. Since the goal is to keep the shampoo slightly acid, the term "pH balanced" is actually a misnomer. We want the balance to be tipped slightly to the acidic side.

Any washing liquid will be a mixture of various substances, usually water-based.\n\nStandard components are detergents - molecules with a polar and an apolar end which can absorb on fatty (lipophile) substances and provide solution in the polar medium with their polar end. Classical soaps are sodium salts of fatty acids.\n\nOther ingredients vary strongly with the purpose of the washing up liquid. Perfumes, enzymes to digest specific types of pollutants, bleaching agents (usually oxydative), emulgators, Calcium-removers (like polyphosphate, zeoliths or chelating agents)...

Altoghether, it doesn't matter. Most shampoo has the same active ingredients with different scents. The exceptions are only with dandruff or prescription shampoo.

A detergent composition containing efficient enduring perfume composition is provided. Specifically, the detergent composition comprises: a perfume composition comprising at least about 70% of enduring perfume ingredients characterized by having boiling points, measured at the normal, standard pressure, of about 250.degree. C. or higher, and an octanol/water partitioning coefficent P of about 1,000 or higher, i.e., having a logP, or calculated logP, of about 3 or higher. The perfume is substantially free of halogenated fragrance materials and nitromusks. The composition also contains from about 0.01% to about 95% of a detergent surfactant system, preferably containing anionic and/or nonionic detergent surfactants. The compositions can be in the form of granules, liquids, pastes, bars, etc.

In the 1920s, Americans used soap flakes to clean their laundry. The flakes performed poorly in hard water, leaving a ring in the washing machine, dulling colors, and turning whites gray. Procter & Gamble began an ambitious mission to change the way Americans washed their clothes. Researchers discovered two-part molecules which they called synthetic surfactants. Each part of the "miracle molecules" executed a specific function--one pulled grease and dirt from the clothes, while the other suspended dirt until it could be rinsed away. In 1933, this discovery was introduced in a detergent called "Dreft," but it could only handle lightly soiled jobs. The next goal was to create a detergent that could clean heavily soiled clothes. That detergent was Tide®. \n\nCreated in 1943, Tide detergent was the combination of synthetic surfactants and "builders." The builders helped the synthetic surfactants penetrate the clothes more deeply to attack greasy, difficult stains. Tide was introduced to test markets in October 1946 as the world’s first heavy-duty detergent. Consumer response was immediate and intense. Tide detergent outsold every other brand within weeks. It became so popular that store owners were forced to limit the quantity purchased per customer. \n\nTide detergent was improved 22 times during its first 21 years on the market, and Procter & Gable still strives for perfection. Each year, researchers duplicate the mineral content of water from all parts of the United States and wash 50,000 loads of laundry to test Tide detergent’s consistency and performance.

Well, I guess the water supply in the UK is hard water. Hard water is water with metal cations in it (mostly calcium and magnesium). Oh, and shampoo has EDTA in it, which "eats" the metal cations and turns hard water into soft water. This is why shampoo lathers in hard water but soap does not. Look at the back of the shampoo bottle, you'll see some form of EDTA in it (mine has tetrasodium EDTA).

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/

They are chemical cousins but not identical  Baking soda is sodium acid carbonate, NaHCO3, while washing soda is sodium carbonate, Na2CO3.  Whether you can get away with the substitution depends on the nature of the project.

The lower the surface tension of a detergent solution the higher its dirt removing ability and viceversa.ie . the better detergent is the one whose soln shows lower capillary rise.

stearic acid and sodium hydroxide form a soap that is soluble in hot water. to my knowledge, the stearic acid in combination with sodium hydroxide should form micelles, but the sebacic acid i don't think so as it's not a fatty acid, and therefor it can't make soaps

Shampoo forms micelles, which cage non-polar soiling oils in our hair and then are rinsed away. Simply running water through our hair does not clean it because the water and soiling oils both are non-polar and do not mix.

Not all shampoo is clear, but I guess if they WERE different, it's because conditioner has more stuff in it. After all, shampoo is to clean your hair, why would you want to put a whole bunch of crap in it. As for that girl who said her shampoo isn't clear, it's probably conditioning shampoo.
