INTRODUCTION
What is soy lecithin? Lecithin is a food additive that comes from several sources – one of them being soy. It’s generally used as an emulsifier, or lubricant, when added to food, but also has uses as an antioxidant and flavor protector.
Soy lecithin is composed of choline, fatty acids, glycerol, glycolipids, phospholipids, phosphoric acid and triglycerides.
The diverse forms in which lecithin is available – fluid, powder and granules – make it even more suitable to use as per industry specific demands. With additional processing, fluid lecithin can also be hydrolysed, fractionated, hydroxylated and acetylated for very specific industry applications.
Manufacture
Soy Lecithin is made from fresh gums, during de-gumming of Soybean Oil obtained from Soybean seeds.

Applications
It is used in human food, pharmaceuticals, animal feed, paints, and other industrial applications.
| In food industry as an emulsifier, stabilizer, lubricate, release agent, antioxidant and dispersant. |
| In the pharmaceutical industry, it acts as a wetting agent, stabilizing agent and a choline enrichment carrier, helps in emulsification and encapsulation, and is a good dispersing agent. It can be used in manufacture of intravenous fat infusions and for therapeutic use. |
| In animal feed, it enriches fat and protein and improves pelletization. |
| In the paint industry, it forms protective coatings for surfaces with painting and printing ink, has antioxidant properties, helps as a rust inhibitor, is a color-intensifying agent, catalyst, conditioning aid modifier, and dispersing aid; it is a good stabilizing and suspending agent, emulsifier, and wetting agent, helps in maintaining uniform mixture of several pigments, helps in grinding of metal oxide pigments, is a spreading and mixing aid, prevents hard settling of pigments, eliminates foam in water-based paints, and helps in fast dispersion of latex-based paints. |
| Also, may be used as a release agent for plastics, an anti-sludge additive in motor lubricants, an anti-gumming agent in gasoline, and an emulsifier, spreading agent, and antioxidant in textile, rubber, and other industries. |

L-Phenylalanine (L-Phe) is an essential and proteinogenic amino acid that helps build proteins and produces brain chemicals like dopamine and norepinephrine. L-Phenylalanine is one of the 20 standard amino acids that form long chains called polypeptides (proteins).The body cannot produce it, so it must be obtained through diet or supplements.
L-carnitine Hydrochloride is a water soluble, stable salt form of L- Carnitine. It is a naturally occurring amino acid derivative. It is often used as a dietary supplement due to its role in energy production and fat metabolism.
Dimenhydrinate is an antihistamine drug commonly used to prevent and treat motion sickness, nausea, and vertigo. It is a combination of diphenhydramine and 8-chlorotheophylline, where the latter reduces the sedative effects of diphenhydramine. It is available in tablet, liquid, and injectable forms under various brand names.
o-Nitrophenyl Disulfide is a chemical compound used in organic chemistry and biochemistry. It is a disulfide derivative where two o-nitrophenyl groups are connected by a disulfide bond (-S-S-) It is used in various organic synthesis reactions, as a reagent in the preparation of thiol-reactive compounds, in pharmaceutical research and laboratory applications.
Tetrasodium pyrophosphate (TSPP) anhydrous is a white, crystalline or granular inorganic compound, soluble in water but insoluble in alcohol. TSPP is widely used in food, industrial, and cleaning applications due to its sequestrant, dispersing, buffering, and emulsifying properties.
Potassium sodium tartrate commonly known as Rochelle salt, is a double salt of tartaric acid. It is a white crystalline solid that is highly soluble in water. This compound is well known for its piezoelectric properties and has been historically used in various scientific and industrial applications.
Tert-Amyl Alcohol (TAA) also known as 2-Methyl-2-butanol, is a branched-chain alcohol. It is a colorless, flammable liquid with a mild alcoholic odor and moderate water solubility. Due to its unique structural properties, it is widely used as basic organic chemical in synthetic fragrances, pharmaceuticals and pigment industries.
Lithium orotate is a compound consisting of lithium, an alkali metal, and orotic acid, a natural substance involved in nucleic acid metabolism. It is a popular dietary supplement due to its potential neuroprotective and mood-stabilizing effects.
Quinuclidinone Hydrochloride is a derivative of bicyclic amine quinuclidine. The hydrochloride form of quinuclidinone is the salt form, often used for its stability in different reactions. Quinuclidinone Hydrochloride is typically used as an intermediate in the synthesis of various pharmaceuticals and other chemical products.
