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