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.
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.
Methyl Paraben
Methyl Paraben is a white to off-white crystalline powder widely used as an antimicrobial preservative in cosmetics, pharmaceuticals, and food products. It is a member of the paraben family of preservatives known for their effectiveness against a broad spectrum of bacteria and fungi. Methyl Paraben helps extend the shelf life of products by preventing microbial growth without affecting the product's texture or color.
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.
Propylparaben (Prop BH)
Prop BH, also known as Propylparaben or Propyl 4-Hydroxybenzoate, is an organic compound belonging to the paraben family of preservatives. It appears as colorless small crystals or a white crystalline powder with a characteristic mild odor and a slightly bitter taste. The compound is practically insoluble in cold water but readily soluble in alcohols, ethers, and other organic solvents. Propylparaben is widely recognized for its broad-spectrum antimicrobial activity, particularly effective against molds, yeasts, and bacteria. Propylparaben is manufactured for use as a preservative in various industrial applications and is not intended for direct human consumption without appropriate certification.
Veegum
Veegum is a purified magnesium aluminum silicate clay known for its excellent suspending, thickening, and stabilizing properties. It is widely used in pharmaceuticals, cosmetics, and industrial applications as a rheology modifier, suspension stabilizer, and emulsifier. Veegum enhances the texture, consistency, and stability of formulations, providing improved performance in both liquid and semi-solid systems.
Vitamin B12( Cyanocobalamin)
Vitamin B12 Cyanocobalamin BP is a pharmaceutical-grade form of vitamin B12, standardized according to the British Pharmacopoeia (BP). It is an essential nutrient involved in red blood cell formation, neurological function, and DNA synthesis. This stable, synthetic cyanocobalamin is widely used in pharmaceuticals, nutraceuticals, and fortified foods to prevent and treat vitamin B12 deficiency.
Vitamin B3 (Nicotinamide)
Vitamin B3 Nicotinamide, also known as Niacinamide, is a water-soluble amide form of vitamin B3. It plays a crucial role in cellular energy production and DNA repair by serving as a precursor for coenzymes NAD and NADP. Nicotinamide is preferred in many pharmaceutical and cosmetic applications due to its stability and lower side-effect profile compared to niacin. It is widely used in pharmaceuticals, nutraceuticals, cosmetics, and food fortification.
