Bronopol
Bronopol (2-Bromo-2-nitropropane-1,3-diol) is a water-soluble, white crystalline powder or granules with a slight odor. It is a synthetic antimicrobial agent widely used as a preservative in personal care products, pharmaceuticals, cosmetics, and industrial applications. Bronopol exhibits broad-spectrum bactericidal and fungicidal activity, making it effective against a wide range of microorganisms. It works by releasing active formaldehyde slowly, which disrupts microbial metabolism and reproduction.
Cellulose Ether
Cellulose ether refers to a group of chemically modified cellulose derivatives where hydroxyl groups on the cellulose backbone are substituted with ether groups such as methyl, hydroxyethyl, or carboxymethyl groups. These modifications improve solubility, viscosity, and film-forming properties while maintaining biodegradability and non-toxicity. Cellulose ethers are white to off-white powders or granules that dissolve in water to form viscous, stable solutions. They are widely used as thickeners, binders, stabilizers, and film formers in industries such as construction, pharmaceuticals, cosmetics, food, and paper.
Prednisolone Sodium Phosphate
Prednisolone Sodium Phosphate is a water-soluble ester of prednisolone, a synthetic glucocorticoid steroid with potent anti-inflammatory and immunosuppressive effects. Its enhanced solubility makes it suitable for injectable formulations and rapid systemic action. It is commonly used to treat various inflammatory, allergic, and autoimmune conditions, offering effective modulation of immune responses and inflammation.
Promethazine
Promethazine is a first-generation antihistamine with potent sedative, antiemetic, and anticholinergic properties.

Vitamin B3 (Niacin)
Vitamin B3 Niacin, also known as Niacin or Nicotinic Acid, is a water-soluble vitamin essential for energy metabolism and enzymatic reactions in the body. It plays a key role in the synthesis of coenzymes NAD and NADP, which are critical for cellular respiration and DNA repair. Niacin is widely used in pharmaceuticals, nutraceuticals, food fortification, and animal nutrition to prevent niacin deficiency and support overall health.
Vitamin B6 (Pyridoxine HCL)
Vitamin B6 Pyridoxine HCL, also known as Pyridoxine Hydrochloride, is a water-soluble form of vitamin B6 used extensively in the pharmaceutical, food, and feed industries. It is essential for protein metabolism, neurotransmitter synthesis, red blood cell formation, and immune function. As a stable and bioavailable form of B6, it is widely incorporated in dietary supplements, fortified foods, clinical nutrition, and animal feed.
Vitamin B7 (Biotin)
Vitamin B7 Biotin, also known as Biotin, is a water-soluble B-complex vitamin essential for various metabolic processes. It serves as a coenzyme for carboxylase enzymes involved in the metabolism of fatty acids, amino acids, and glucose. Biotin is vital for healthy skin, hair, nails, and nervous system function. It is widely used in the pharmaceutical, nutraceutical, food, cosmetic, and animal nutrition industries.
