The Belonging of Methyl Caprylate-Caprate

The fatty acid is the end of the aliphatic hydrocarbon chain length of carboxylic acid added to the terminal at the other end of the carboxyl (-COOH) group. The general formula R-(CH2) N-COOH. Fatty acids is the reaction of the main branches and even 12 and 22 carbon atoms between the carbon atoms in length and form of glycerine, plant, animal and microbial lipids (fat-soluble components of living cells). Fatty acids all have common names respectively lilk lauric (C12), MyrIstic (C14), palmitic (C16), stearic (C18), oleic (C18, unsaturated), and linoleic (C18, polyunsaturated) acids. The saturated fatty acids have no solid bonds, while oleic acid is an unsaturated fatty acid has one solid bond (also described as olefinic) and polyunsaturated fatty acids like linolenic acid contain two or more solid bonds. 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. 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). Stearic acid ( also called Octadecanoic Acid)  is nature's most common long-chain fatty acids, derived from animal and vegetable fats. It is widely used as a lubricant and as an additive in industrial preparations. It is used in the manufacture of metallic stearates, pharmaceuticals, soaps, cosmetics, and food packaging. It is also used as a softener, accelerator activator and dispersing agent in rubbers. Oleic acid (systematic chemical name is cis-octadec-9-enoic acid) is the most abundant of the unsaturated fatty acids in nature.

Fatty Acid Esters are used as raw material of emulsifiers or oiling agents for foods, spin finishes and textiles; lubricants for plastics;  Paint and ink additives; surfactants and base materials for perfumery. They are used as solvents or cosolvents, oil carrier in agricultural industry.

A Description of Palmitate

Palmitic acid, or hexadecanoic acid in IUPAC nomenclature, is one of the most common fatty acids found in animals and plants. It is a major component of the oil from palm trees (palm oil, palm kernel oil and coconut oil). However, palmitic acid can also be found in meats, cheeses, butter, and dairy products.

Its molecular formula is CH3(CH2)14CO2H. As its name indicates, it is a major component of the oil from palm trees (palm oil, palm kernel oil, and coconut oil). Palmitate is a term for the salts and esters of palmitic acid. The palmitate anion is the observed form of palmitic acid at basic pH.
Palmitic acid has been shown to kill the beta cells in the pancreas that are responsible for the secretion of insulin, and to suppress the body's natural appetite-suppressing signals from leptin and insulin -- the key hormones involved in weight regulation.
Aluminum salts of palmitic acid and naphthenic acid were combined during World War II to produce napalm (aluminum naphthenate and aluminum palmitate). The word "napalm" is derived from the words naphthenic acid and palmitic acid.

Niche Uses of Methyl Stearate

Being inexpensively available and chemically benign, stearic acid finds many niche applications. When making plaster castings from a plaster piece mold or waste mold and when making the mold from a shellacked clay original. In this use, powdered stearic acid is dissolved in water and the solution is brushed onto the surface to be parted after casting. This reacts with the calcium in the plaster to form a thin layer of calcium stearate which functions as a release agent. When reacted with zinc it forms zinc stearate which is used a lubricant for playing cards (fanning powder) to ensure a smooth motion when fanning. In compressed confections it is used as a lubricant to keep the tablet from sticking to the die.

Fatty acids are classic components of candle-making. Stearic acid is used along with simple sugar or corn syrup as a hardener in candies. Stearic acid is used to produce dietary supplements.

In fireworks, stearic acid is often used to coat metal powders such as aluminium and iron. This prevents oxidation, allowing compositions to be stored for a longer period of time. Stearic acid is a common lubricant during injection molding and pressing of ceramic powders. It is also used as a mold release for foam latex that is baked in stone molds.

A Little Information of Methyl Vegetable Oil Acid Ester

Biodiesel refers to a vegetable oil- or animal fat-based diesel fuel consisting of long-chain alkyl (methyl, propyl or ethyl) esters. Biodiesel is typically made by chemically reacting lipids (e.g., vegetable oil, animal fat (tallow)) with an alcohol producing fatty acid esters.

Methyl vegetable oil acid ester  is light yellow oil liquid. The saponification value is 185-195mgKOH/g .It is good natural fatty acid methyl ester which are widely used in cosmetics and detergent and armoa and fragrance etc.

Biodiesel is meant to be used in standard diesel engines and is thus distinct from the vegetable and waste oils used to fuel converted diesel engines. Biodiesel can be used alone, or blended with petrodiesel. Biodiesel can also be used as a low carbon alternative to heating oil.

Safety of Fatty Acid Methyl Esters

Fatty Acid Methyl Esters are widely applied indirectly in food, pharmaceutical, cosmetic and industrial applications. Numerous volumes of these materials are shipped regularly by sea and care needs to be taken to avoid contamination with noxious materials that could effect the safety of the final product and effect the processing of the oleochemical itself. Because of it oleochemical producers ensure that when shipping by sea the immediate previous cargo is on either of the Acceptable Immediate Previous Cargo lists set up by FOSFA and NIOP. The former is recognised in principle in Directive 96/3/EC. Methyl esters themselves are on both the FOSFA and the NIOP lists and provide useful safe previous cargoes for the shipment of oils and fats intended for use in food products following further processing.

The European Oleochemicals and Allied Products Group were surprised and concerned when an SCF AD Hoc Group proposed the removal of Fatty Acid Methyl Esters from the list of Acceptable Immediate Previous Cargoes appended to Directive 96/3/EC. This group of products have generally been thouht safe and have already been given Regulatory Clearance for a wide range of direct and indirect food uses. Indeed the SCF's First Report on Chemically Defined Flavouring Substances (November 1995) lists methyl esters from the butyrate to the myristate in Category 1 (substances considered safe to use), the safest of the 5 categories used.

How Does Fatty Acid Esters Work?

Fatty acid esters are used as raw material of emulsifiers or oiling agents for foods, spin finishes and textiles; lubricants for plastics;  Paint and ink additives; surfactants and base materials for perfumery. They are used as solvents or cosolvents, oil carrier in agricultural industry.

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. 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. Fatty acids all have common names respectively lilk lauric (C12), MyrIstic (C14), palmitic (C16), stearic (C18), oleic (C18, unsaturated), and linoleic (C18, polyunsaturated) acids. 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. 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. 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). Stearic acid ( also called Octadecanoic Acid)  is nature's most common long-chain fatty acids, derived from animal and vegetable fats.
