INTRODUCTION
Potassium benzoate (E212), the potassium salt of benzoic acid, is a food preservative used to prevent the growth of mold, yeast and some bacteria. It works best in low-pH products, below 4.5, where it exists as benzoic acid.
MANUFACTURE
Potassium benzoate is produced by oxidizing toluene to benzoic acid followed by a neutralization with potassium hydroxide.

Dibutyl sulfide is an organosulfur. It is a clear, colorless to pale yellow liquid characterized by a strong sulfur-like odor and is primarily used as an intermediate in chemical synthesis, specialty organic manufacturing, and research applications. The compound exhibits good solvency properties and moderate thermal stability, making it useful in industrial and laboratory processes involving sulfur-containing organic compounds.
Oleylamine is a long-chain (C18) primary fatty amine derived from natural fatty acids, typically sourced from vegetable oils. It is produced from oleic acid through conversion of the carboxylic acid group (–COOH) into an amine group (–NH₂). With its optimal balance of hydrophobic chain length and reactive amine functionality it serves as a versatile and dependable building block for high-performance formulations.
Sodium Hyaluronate is the sodium salt of hyaluronic acid, a naturally occurring glycosaminoglycan known for its exceptional ability to retain moisture, along with its viscoelastic and biocompatible properties, making it highly valuable across pharmaceutical, cosmetic, and biomedical applications.
Pyrazinamide is a first-line antitubercular drug used in combination therapy for the treatment of tuberculosis (TB). It is a synthetic pyrazine derivative and acts as a prodrug, which is converted into its active form (pyrazinoic acid) inside Mycobacterium tuberculosis.
6-Bromopyridine-2,3-diamine is a heterocyclic organic compound belonging to the class of substituted pyridines. It is used mainly as an intermediate in pharmaceuticals and agrochemicals.
Magnesium trisilicate is an inorganic compound commonly used in pharmaceutical and gastrointestinal (GI) preparations due to its dual action. It is usually produced as a white, odorless, fine powder. It helps bind toxins or irritants in the gastrointestinal tract and occasionally used in formulations for its stabilizing properties.
Choline salicylate is a salicylate salt formed from choline and salicylic acid. It is a non-steroidal anti-inflammatory agent (NSAID-type compound) mainly used for its analgesic, anti-inflammatory, and mild antiseptic properties. Unlike acetylated salicylates, it is less irritating to the gastric mucosa and is commonly used in topical oral preparations such as gels and mouth paints.
TensyraTM N-10 (Octoxinol 10; tert-octyl phenyl ethoxylate) is a non-ionic surfactant known for its excellent solubilizing and membrane-permeabilizing properties. It features a hydrophilic polyethylene oxide chain paired with a lipophilic aromatic hydrocarbon group.It readily breaks down biological membranes to lyse cells, solubilize proteins, and permeabilize cell membranes for assays.
Teprenone (Geranylgeranylacetone, GGA) is a mixture of the all-trans and mono-cis isomers of 6,10,14,18-tetramethyl-5,9,13,17-nonadecatetraen-2-one (in a weight ratio of 3:2). It is an acyclic isoprenoid compound with a structure like retinoids and is widely used for the treatment of gastrointestinal ulcers.
