INTRODUCTION
Potassium sorbate, the potassium salt of sorbic acid, is a white odorless and tasteless salt that is very soluble in water. Potassium sorbate is an antimicrobial preservative. It exhibits both antibacterial and antifungal properties used in pharmaceuticals, foods, enteral preparations and cosmetics.
Manufacture
While sorbic acid occurs naturally in rowan and hippophae berries, virtually all of the world’s supply of sorbic acid, from which potassium sorbate is derived, is manufactured synthetically. Potassium sorbate is produced industrially by neutralizing sorbic acid with potassium hydroxide.

APPLICATIONS |
---|
Potassium sorbate is widely used in a number of foods as a preservative in beverages (fruit juices, wine and cider), cheese, baked goods, mayonnaise-based products, nuts, olives, syrups, jellies and jams. |
It is used as a bacteriostatic and preservative in meat, products based on fish and eggs, cooked shrimps, sausage casings and flavored dairy products. |
As a preservative, it is also used for dehydrated foods like jerky and dried fruit, as it does not leave an after taste. |
One of its properties is that it is used as an anti-microbial agent that can stop the growth and spread of harmful bacteria, mold and yeast. |
Its activity increases as pH of the product decreases due to the formation of undissociated acid. |
It increases the shelf life of foods, so many dietary supplements also include it. |
It is commonly used in as wine stabilizer and is added to a finished wine before bottling to reduce the possibility of re-fermentation by yeast as it is a yeast growth inhibitor; it will not stop a fermentation that is in progress, but it will stop a fermentation from re-starting. |

Boron trifluoride tetrahydrofuran complex, is a colorless liquid that is commonly used as a colorless liquid that is commonly used as a Lewis acid catalyst in various organic reactions. It has a wide range of applications in the synthesis of pharmaceuticals, polymers, and other organic compounds
Nicotinamide riboside chloride (NRCL) is a unique form of vitamin B3. As a precursor to nicotinamide adenine dinucleotide (NAD+), a crucial coenzyme involved in various cellular processes, it has sparked interest in the realms of aging, metabolism, and overall cellular health.
Tetrachlorvinphos (popularly known as TCVP) is an agrochemical belonging to class of organophosphates. It is a non-systemic insecticide and acaracide having widespread uses in crop protection, public health, and animal hygiene.
Sodium Starch Glycolate (SSG) is a very fine free flowing powder that is white or off white in color and has almost no odor. Its property of insolubility is remarkable, with complete insolubility in most organic solvents, and even in water. It is a sodium salt of carboxyl ether of starch and is appreciated for its stability and binding properties.
3-([Ethyl(3-methylphenyl)amino]methyl) benzenesulfonic acid is an organic sulfonic acid, a white crystalline solid, which is widely used as a catalyst, acidifying agent, and a reagent in organic synthesis.
Sodium trifluoroacetate is a colorless organic solid belonging to category of fluoro compounds. It acts as a versatile trifluoromethylation agent in chemicals synthesis and is used to produce an array of chemical intermediates.
Iodopropynyl butylcarbamate, also known as IPBC, is an antimicrobial ingredient commonly used in cosmetics. It appears as a white, crystalline powder. It is not a paraben; it belongs to a different chemical class called carbamates. It is soluble in both water and oil-based systems. IPBC was invented in the 1970s and has a long history of effective use as an antifungal technology.
Stevia extract with Rebaudioside A (98%) is one of the sweet tasting steviol glycoside, extracted and purified from Stevia rebaudiana (Bertoni) – a small perennial shrub also known as “Honey leaf”. The leaves of S. rebaudiana contain more than 30 different steviol glycosides, among which stevioside and rebaudioside A are present in the highest levels. It is non-nutritive and tastes approximately 200-300 times sweeter than sucrose.
Protoporphyrin IX dimethyl ester, abbreviated PPMX, is an organic moiety belonging to category porphyrins. On exposure to light, PPMX releases reactive oxygen that can be used to destroy targeted cancer cells and thus it find applications largely in medicines.
