INTRODUCTION
Glyceryl Stearate Citrate (GSC) is a plant-derived, biodegradable emulsifier commonly used in cosmetics and personal-care products. It functions primarily as an anionic oil-in-water (O/W) emulsifier, helping blend oils and water into smooth, stable creams and lotions. Its natural origin and gentle profile make it popular in eco-certified, organic, and sensitive-skin formulations.
MANUFACTURE
Manufactured through high-level esterification of glycerol, stearic acid, and citric acid.

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.
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.
