INTRODUCTION
Sodium Alginate is a linear polysaccharide derivative of alginic acid processed from brown algae. The conversion of alginic acid to sodium alginate allows its solubility in water, which assists its extraction. Sodium Alginate is used as a hydrocolloid in various applications such as food manufacturing and pharmaceuticals, as an emulsifier in textiles and cosmetics industries and in dentistry to make molds. It is widely used in Molecular Gastronomy.

Applications
| Pharmaceuticals | Pharma grade Sodium Alginate and Alginic Acid is widely used in pharmaceutical preparations, tissue engineering, clinical treatment and cell culture. It is also used as microencapsulated material and cold resistant agent for cells. In addition, can be used as thickening agent for external ointments, oral tablets for increasing viscosity and forming gel barrier, thus prolonging the drug release time and reduce adverse reactions. It is also added in antibiotic, insulin and hormone drug solution. |
| Food Industry | Sodium Alginate is a highly viscous purified product used as a food additive, and as a thickening agent, gelling agent, emulsifier and stabilizer. It is used to enhance the texture of noodles. Also used in Vegan meat, Noodles, Ice creams, Lactic Drinks, Breads, Puddings, Yoghurts, Sauce, Cookies, Desserts, Jelly, Cheese, Spherification, etc. |
| Cosmetics | Sodium Alginate is compatible with a variety of emulsifiers and other skin ingredients. It is an excellent carrier for antioxidants and other anti-aging ingredients, and offers a heightened skin feel. It will help to soften, hydrate and soothe skin and leave it feeling silky and soft. It is used to create a skin care serum or hair gel using water, infusions, distillates and water-soluble extracts etc. |
| Impressions | Sodium Alginate can react with calcium salts forming a heat – irreversible gel. It is widely used in impression material (Dental, Hand and Leg, study models, portraits etc). Normally for impression material it is mixed with Calcium Sulfate (Gypsum), Tri Sodium Phosphate, diatomaceous earth, zinc oxide, potassium titanium fluoride etc. Alginate impression materials are easy to use, less expensive, with quick setting time. It has low water content, steady viscosity and long shelf life. Alginates fine particle size makes impression surface smooth and thus more identical to the original mould. |

Undecylenic acid is an unsaturated fatty acid naturally derived from castor oil. It is a colorless to pale yellow liquid with antifungal and antimicrobial properties. Chemically known as 10-undecenoic acid, it contains an 11-carbon chain with one double bond and is widely used in pharmaceuticals
5-Nitro Isophthalic Acid (5-NIPA) is an aromatic organic compound derived from isophthalic acid. The presence of two carboxylic acid groups along with a nitro substituent at the 5-position makes it a valuable intermediate in the manufacture of fine chemicals, pharmaceuticals, dyes, pigments, and advanced materials.
Trichloroacetonitrile is a halogenated organic compound belonging to nitrile family. Its strong electrophilic character makes it a valuable intermediate in organic synthesis. It readily undergoes hydrolysis, particularly under acidic or basic conditions, yielding trichloroacetamide and related derivatives.
Zinc Dialkyl Dithio Phosphate (ZDDP) belongs to a family of coordination compounds classified as members of transition metal dithiophosphate.
ZDDP is widely used based on a combination of different selected alcohols thus providing antiwear performance and enhanced thermal and hydrolytic stability. In combination with other additives, it is especially used for the formulation of hydraulic fluids, industrial gear oils, metalworking fluids, greases and automotive engine oils.
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.
