INTRODUCTION
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.
MANUFACTURE:
It is typically produced through microbial fermentation using strains such as Streptococcus, followed by a series of purification steps including filtration, precipitation, and drying to yield a high-purity, stable powder form suitable for various 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.
Ciclopirox Olamine (CPO) is the N-oxide of a 2 -hydroxy pyridine derivative that carries antifungal, antibacterial, and anti-inflammatory properties. It is composed of 6-cyclohexyl-1-hydroxy-4-methyl-2(1H)-pyridone combined with 2 aminoethanol (olamine) in a 1:1 ratio.
N,N-Dimethylglycine sodium salt (DMG Na) is the sodium salt form of N,N-dimethylglycine, a tertiary amino acid derivative is white to off white crystalline solid, freely soluble in water.
Blown Castor Oil (15-17 Poise) is a modified grade of Castor oil. The “15-17 Poise” specification refers to its viscosity range, indicating a medium-viscosity blown oil suitable for industrial applications requiring improved body, tackiness, and elasticity compared to regular castor oil.
