Bismuth Subgallate
Bismuth Subgallate is a pale yellow, odorless, tasteless powder composed of bismuth and gallic acid derivatives. It is widely used as an internal deodorant for controlling odor from flatulence and stool, especially in patients with gastrointestinal conditions or post-surgery stomas. It also serves as a mild astringent and has hemostatic properties, making it useful in wound care products. Due to its insolubility in water and stability, it is suited for oral and topical formulations.
Borax Pentahydrate
Borax Pentahydrate (sodium tetraborate pentahydrate) is an inorganic compound and a hydrated form of borax. It typically appears as colorless to white crystalline granules or powder. This compound contains five molecules of water of crystallization per formula unit, distinguishing it from other borax hydrates such as the decahydrate form. Borax Pentahydrate is widely used across industries including detergents, glass production, agriculture, and cosmetics, valued for its buffering capacity, emulsification, and antiseptic properties. It is soluble in water and exhibits alkaline properties in aqueous solution.
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.
Cetirizine Dihydrochloride
Cetirizine Dihydrochloride is a second-generation antihistamine widely used to relieve allergy symptoms such as hay fever, urticaria (hives), and other allergic conditions. It is the dihydrochloride salt form of cetirizine, presenting as a white to off-white crystalline powder that is odorless or nearly odorless and slightly bitter in taste. Cetirizine Dihydrochloride acts as a selective antagonist of peripheral H1 histamine receptors, preventing the effects of histamine and thereby reducing allergic symptoms without causing significant sedation. It is a commonly prescribed active pharmaceutical ingredient (API) in oral tablets, syrups, and capsules.
Chlorpheniramine Maleate
Chlorpheniramine Maleate is a first-generation alkylamine antihistamine used primarily to relieve allergy symptoms by blocking H1 histamine receptors. It appears as a white or off-white crystalline powder, freely soluble in water and alcohol. Known for rapid onset and moderate duration of action, it’s widely formulated in pharmaceuticals. It also exhibits mild anticholinergic and sedative effects.
Citric Acid Anhydrous
Citric Acid Anhydrous is a white, crystalline organic acid widely used across food, pharmaceutical, cosmetic, and industrial sectors. It is the anhydrous form of citric acid, meaning it contains no water molecules in its crystal lattice, resulting in higher purity and more concentrated acidic properties compared to its monohydrate form. Derived from natural sources like citrus fruits or produced via microbial fermentation, citric acid anhydrous is valued for its sour taste, excellent chelating ability, and buffering capacity. It serves as a natural preservative, pH adjuster, antioxidant synergist, and cleaning agent, making it a versatile ingredient in many formulations.
Clotrimazole BP2000
Clotrimazole BP2000 is a broad-spectrum antifungal agent belonging to the imidazole class. It appears as a white to off-white crystalline powder that is practically insoluble in water but soluble in organic solvents like ethanol and chloroform. Clotrimazole is widely used in pharmaceutical formulations for the treatment of fungal infections affecting the skin, mucous membranes, and nails. Its mechanism involves inhibition of ergosterol synthesis, a vital component of fungal cell membranes, leading to increased cell permeability and fungal cell death. BP2000 indicates compliance with British Pharmacopoeia standards ensuring high purity and consistent quality suitable for pharmaceutical applications.
Melamine
Melamine is an organic compound widely used as a raw material in the production of melamine-formaldehyde resins, laminates, adhesives, coatings, and flame retardants. It offers excellent hardness, thermal stability, and chemical resistance. Supplied in 25kg bags, melamine is a white crystalline powder with high nitrogen content, making it a valuable additive in plastics, construction materials, and surface treatments.
