A soap is a salt of a fatty acid. Beilstein/REAXYS Number 4046357 . Since glycerol is an alcohol, while fatty acids are carboxylic acid, the process is call esterification, and it is a condensation reaction. Salts of sodium, potassium, calcium, and magnesium are formed when fatty acids react with these salts. : 93348-22-2 EINECS (EC) No. Fatty acids are carboxylic acids with a long unbranched hydrocarbon (aliphatic) chains. It is used as laundry soap. MDL number MFCD00004438. Technical Evaluation Report Citric acid and its salts Handling/Processing February 17, 2015 Page 3 of 31 69 70 Figure 2: Citrate salts molecular structures. Acetic acid is completely miscible with water because it contains only 1 methyl group. Sodium carbonate or sodium hydroxide is then used to convert the fatty acids to their sodium salts (soap molecules): Looking Closer: Soaps Ordinary soap is a mixture of the sodium salts of various fatty acids, produced in one of the oldest organic syntheses practiced by humans (second only to the fermentation of sugars to produce ethyl alcohol). Saponification is a process by which triglycerides are reacted with sodium or potassium hydroxide (lye) to produce glycerol and a fatty acid salt called "soap." Molecular Weight 304.44 . Linear Formula CH 3 (CH 2) 7 CH=CH(CH 2) 7 COONa . Soaps are the sodium and potassium salts of fatty acids. Soaps are just potassium or sodium salts of long-chain fatty acids. The ionic (highly polar, charged) nature of salts typically makes them water soluble. The potassium salt of long chain fatty acid is known as soft soap, as it produces more lather. Palmito-oleic acid is more soluble than palmitic acid. 172.863 Salts of fatty acids. (ChemBioDraw 2014) 71 72 The citrate salts come with various levels (mono-, di-, tri-) of the metal cations (calcium, potassium or 73 sodium… : 297-163-5 Molecular Formula: RCH(SO3Na)COOCH3 R:C16-18 alkyl Characteristics: 1, High effect surfactant produced by natural plant and animal oil and fat. Sodium salts of fatty acids from Mortierella alpina oil View - notice PDF : FDA Mainterm (SATF): 977038-15-5 ; SODIUM SALTS OF FATTY ACIDS: FDA Regulation: FDA PART 172 -- FOOD ADDITIVES PERMITTED FOR DIRECT ADDITION TO FOOD FOR HUMAN CONSUMPTION Subpart I--Multipurpose Additives Sec. When sodium hydroxide is used, a hard soap is produced. The triglycerides are most often animal fats or vegetable oils. PubChem Substance ID 24898044 Fatty acids form salts with alkali and alkaline earth metal. During saponification, ester reacts with an inorganic base to produce alcohol and soap. It is used as toilet soap and shaving soap. Fatty acids have a wide range of commercial applications. Figure above shows that, we can separate the glycerol molecule from the fat molecule, and at the same time, produce three sodium salt of fatty acid. EC Number 205-591-0. The sodium salt of long chain fatty acid is known as hard soap. It is difficult to dissolve in water. For example, they are used not only in the production of numerous food products but also in soaps, detergents, and cosmetics. Sodium oleate ≥99% Synonym: cis-9-Octadecenoic acid sodium salt, Oleic acid sodium salt CAS Number 143-19-1. 61789-30-8 - Fatty acids, coconut oil, potassium salts - Searchable synonyms, formulas, resource links, and other chemical information. 2, Excellent emulsification, wetting, softening, anti-hard water. Generally, it occurs when triglycerides are reacted with potassium or sodium hydroxide (lye) to produce glycerol and fatty acid salt, called ‘soap’. Some skin-care products contain fatty acids, which can help maintain healthy skin appearance and function.
