What is Methyl stearate

Methyl stearate occurs like a off-white to cream or light yellow paste. Fatty Acids are aliphatic carboxylic acid with varying hydrocarbon lengths at one end of the chain joined to terminal carboxyl (-COOH) group at the other end. Esters react with acids to liberate heat along with alcohols and acids. The general formula is R-(CH2)n-COOH. Fatty acids are predominantly unbranched and those with even numbers of carbon atoms between 12 and 22 carbons long react with glycerol to form lipids (fat-soluble components of living cells) in plants, animals, and microorganisms. Boiling point :442 - 443 C. Heat is also generated by the interaction of esters with caustic solutions.

The saturated fatty acids have no double bonds, while oleic acid is an unsaturated fatty acid has one double bond (also described as olefinic) and polyunsaturated fatty acids like linolenic acid contain two or more double bonds. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Melting point:  31 -35 C. Fatty acids all have common names respectively lilk lauric (C12), MyrIstic (C14), palmitic (C16), stearic (C18), oleic (C18, unsaturated), and linoleic (C18, polyunsaturated) acids. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. CAS: 112-61-8. Fomular: CH3(CH2)16COOCH3; Molecular weight: 298.51g/mol.
Lauric acid (also called Dodecanoic acid) is the main acid in coconut oil (45 - 50 percent) and palm kernel oil (45 - 55 percent). Nutmeg butter is rich in myristic acid (also called Tetradecanoic acid ) which constitutes 60-75 percent of the fatty-acid content. It is widely used as a lubricant and as an additive in industrial preparations and in the manufacture of metallic stearates, pharmaceuticals, soaps, cosmetics, and food packaging.
Stearic acid ( also called Octadecanoic Acid)  is nature's most common long-chain fatty acids, derived from animal and vegetable fats. Palmitic acid(also called Hexadecylic acid ) constitutes between 20 and 30 percent of most animal fats and is also an important constituent of most vegetable fats (35 - 45 percent of palm oil). Oleic acid (systematic chemical name is cis-octadec-9-enoic acid) is the most abundant of the unsaturated fatty acids in nature.
