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.
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.
Calcium Chloride Dihydrate
Calcium Chloride Dihydrate (CaCl₂·2H₂O) is a hydrated form of calcium chloride, appearing as white crystalline granules or flakes containing two molecules of water of crystallization. It is highly soluble in water and exhibits strong hygroscopic and deliquescent properties. This compound is widely used in industrial, pharmaceutical, food, and agricultural sectors due to its moisture absorption, de-icing, dust control, and calcium supplementation capabilities. Compared to anhydrous calcium chloride, the dihydrate form has lower hygroscopicity but is easier to handle and store.
Calcium Saccharin
Calcium Saccharin is the calcium salt form of saccharin, a synthetic sweetener. It appears as a white to off-white crystalline powder with a sweet taste that is several hundred times sweeter than sucrose (table sugar). Calcium Saccharin is water-soluble and widely used as a non-nutritive sweetener in food and beverage products, pharmaceuticals, and oral care formulations. Due to its stability under heat and acidic conditions, it is ideal for baked goods and beverages. It serves as a sugar substitute for diabetic and calorie-restricted diets and is often used in combination with other sweeteners to improve taste profiles.
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.
