In the manufacture of soap, a hot concentrated solution of sodium hydroxide is added to vegetable oils or animal fats. Vegetable oils and fats contain many different esters, such as glyceryl stearate (formed from an alcohol such as glycerol and a long-chain fatty acid such as stearic acid). Sodium salts of fatty acids (palmitic, stearic, and oleic) form soap, which separates and floats on the surface when...

The most commonly used emulsifiers are sodium, potassium, or ammonium salts of oleic acid, stearic acid, or rosin acids, or disproportionate rosin acids, either singly or in mixture. An aLkylsulfate or aLkylarenesulfonate can also be used or be present as a stabilizer. A useful stabilizer of this class is the condensation product of formaldehyde with the sodium salt of P-naphthalenesulfonic acid. AH these primary emulsifiers and stabilizers are anionic and on adsorption they confer a negative charge to the polymer particles. Latices stabilized with cationic or nonionic surfactants have been developed for special apphcations. Despite the high concentration of emulsifiers in most synthetic latices, only a small proportion is present in the aqueous phase nearly all of it is adsorbed on the polymer particles. 

Soaps are sodium salts of long-chain carboxylic acids such as stearic acid ... 

Sodium stearoyl lactylate (and the similar calcium stearoyl lactylate) is made by combining lactic acid and stearic acid, and then reacting the result with sodium hydroxide or calcium hydroxide to make the sodium or calcium salt. 

Soaps are composed of sodium salts of various fatty acids. These acids include those with the general structure CH3-(CH2) -COOH where n = 6 (caprylic acid), 8 (capric acid), 10 (lauric acid), 12 (myristic acid), 14 (palmitic acid), and 16 (stearic acid). Oleic acid (CH3-(CH2)7-CH=CH-(CH2)7-COOH) and linoleic acid (CH3-(CH2)4-CH=CH- H2-CH=CH-(CH2)7-COOH) are also common soap ingredients. These sodium salts readily dissolve in water, but other metal ions such as Ca2+ and Mg2+ form precipitates with the fatty acid anions. For example, the dissolution of the sodium salt of lauric acid and the subsequent formation of a precipitate of the lauric acid anion with calcium ion is given by... 

Interestingly, in a situation where either magnesium stearate or stearic acid forms a component in the formulation, the organic medicinal compound which is acidic (amobarbital) cannot be extracted with NaOH solution for obvious reason that sodium stearate shall also be extracted along with the salt of the organic acid. Therefore, instead a saturated solution of Ba(OH)2 is employed thereby the insoluble precipitate of barium stearate may be discarded by filtration. 

A typical salt is sodium stearate. This is the salt of stearic acid and sodium hydroxide. The formula of stearic acid is CjjHjjCOOH and the formula of sodium stearate is Na+Cj HjjCOO". 

Soaps are the detergents used since long. Soaps used for cleaning purpose are sodium or potassium salts of long chain fatty acids, e.g., stearic, oleic and palmitic acids. Soaps containing sodium salts are formed by heating fat (i.e., glyceryl ester of fatty acid) with aqueous sodium hydroxide solution. This reaction is known as saponification. 

Sodium, potassium, and calcium salts of ascorbic acids are called ascorbates and are used as food preservatives. These salts are also used as vitamin supplements. Ascorbic acid is water-soluble and sensitive to light, heat, and air. It passes out of the body readily. To make ascorbic acid fat-soluble, it can be esterified. Esters of ascorbic acid and acids, such as palmitic acid to form ascorbyl palmitate and stearic acid to form ascorbic stearate, are used as antioxidants in food, pharmaceuticals, and cosmetics. 

DISSOLVE 1h TEASPOON SOAP POWDER OR FLAKES IN 50 ml WARM WATER. ADD 10 ml HYDROCHLORIC ACID. YOU WILL GET LUMPS OF THE FATTY ACIDS OF WHICH SOAP IS THE SODIUM SALT—MOSTLY STEARIC AND PALMITIC ACIDS. STEARIC ACID IS ADDED TO PARAFFIN IN THE MAKING OF CANDLES. 

All you need is water and plenty of CHsC.H2CHjCHjCH2CH2CH2CH2CH, CHjCHjCIIjCHiCHjCHjCHjCHjCOONa — C17HS5COONa for short, the sodium salt of stearic acid, a substance more generally known as soap. 

Soaps Substances formed by saponification. In this reaction, the oil or fat (glyceryl ester) is hydrolysed by aqueous sodium hydroxide to produce the sodium salt of the fatty acid, particularly sodium stearate (from stearic acid). Soap will dissolve grease because of the dual nature of the soap molecule. It has a hydrophobic part (the hydrocarbon chain) and a hydrophilic part (the ionic head) and so will involve itself with both grease and water molecules. However, it forms a scum with hard water by reacting with the Ca2+ (or Mg2+) present. 

Soap is the sodium salt of a fatty acid (stearic acid). Fatty acids have a long hydrocarbon chain with an acidic group (COOH) at one end. Soap is made by the reaction between stearic acid and sodium hydroxide. 

Answer Mild hydrolysis cleaves the ester linkages between glycerol and fatty acids, forming (a) glycerol and the sodium salts of palmitic and stearic acids (b) D-glycerol 3-phosphocholine and the sodium salts of palmitic and oleic acids. 

Melamine resins are used from this group of thermosets for the manufacture of food contact materials. The melamine can be used in mixtures with urea and in some applications with phenol (< 1 %). The polymerization process is catalyzed in the presence of organic acids (e.g. acetic acid, lactic acid, tartaric acid, citric acid), hydrochloric acid, sulfuric acid, phosphoric acid, sodium and potassium hydroxide, ammonia, calcium or magnesium hydroxide as well as salts of these substances (total < 1 %) which cause the elimination of water and lead to a cured resin system. Stearic acid can be used as a lubricant as can zinc, calcium and magnesium salts, esters of montanic acid with ethandiol and 1,3-butandiol, as well as silicone oil (total < 1 %). 

The alkaline hydrolysis of esters to give carboxylate salts is known as saponification, because it is the process used to make soap. Traditionally, beef tallow (the tristearate ester of glycerol—stearic acid is octadecanoic acid, C17H35CO2H) was hydrolysed with sodium hydroxide to give sodium stearate, Cj HssCC Na, the principal component of soap. Finer soaps are made from palm oil... 

Sodium Stearoyl Lactylate occurs as a cream-colored powder or brittle solid. It is a mixture of sodium salts of stearoyl lactylic acids and minor proportions of other sodium salts of related acids, manufactured by the reaction of stearic acid and lactic acid, neutralized to the sodium salts. It is slightly hygroscopic. It is soluble in ethanol and in hot oil or fat, and is dispersible in warm water. 

PROP Consists of aluminum, calcium, magnesium, potassium, and sodium salts of capric, captyUc, lauric, myristic, oleic, palmitic, and stearic acids manufactured from fats and oils derived from edible sources.
