Palmito-oleic acid is more soluble than palmitic acid. The triglycerides are most often animal fats or vegetable oils. Salts of sodium, potassium, calcium, and magnesium are formed when fatty acids react with these salts. MDL number MFCD00004438. 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. The sodium salt of long chain fatty acid is known as hard soap. The potassium salt of long chain fatty acid is known as soft soap, as it produces more lather. It is used as laundry soap. Molecular Weight 304.44 . PubChem Substance ID 24898044 Beilstein/REAXYS Number 4046357 . 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. During saponification, ester reacts with an inorganic base to produce alcohol and soap. Fatty acids form salts with alkali and alkaline earth metal. : 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. 61789-30-8 - Fatty acids, coconut oil, potassium salts - Searchable synonyms, formulas, resource links, and other chemical information. The non-polar hydrocarbon (aliphatic) tail of soap molecules allows them to be miscible with non-polar (greasy) substances The ionic (highly polar, charged) nature of salts typically makes them water soluble. A soap is a salt of a fatty acid. Hard soap Fatty acids have a wide range of commercial applications. : 93348-22-2 EINECS (EC) No. Soaps are just potassium or sodium salts of long-chain fatty acids. Fatty acids are carboxylic acids with a long unbranched hydrocarbon (aliphatic) chains. 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). Sodium Fatty Acid Methyl Ester Sulfonate (α-MES) Other Name: INCI name: CAS No. Some skin-care products contain fatty acids, which can help maintain healthy skin appearance and function. 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." 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. 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. Linear Formula CH 3 (CH 2) 7 CH=CH(CH 2) 7 COONa . When sodium hydroxide is used, a hard soap is produced. Sodium oleate ≥99% Synonym: cis-9-Octadecenoic acid sodium salt, Oleic acid sodium salt CAS Number 143-19-1. EC Number 205-591-0. 2, Excellent emulsification, wetting, softening, anti-hard water. Soaps are the sodium and potassium salts of fatty acids. Since glycerol is an alcohol, while fatty acids are carboxylic acid, the process is call esterification, and it is a condensation reaction. It is used as toilet soap and shaving soap. (ChemBioDraw 2014) 71 72 The citrate salts come with various levels (mono-, di-, tri-) of the metal cations (calcium, potassium or 73 sodium… Generally, it occurs when triglycerides are reacted with potassium or sodium hydroxide (lye) to produce glycerol and fatty acid salt, called ‘soap’. 172.863 Salts of fatty acids.
