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.
Loperamide HCL
Loperamide HCL is a synthetic opioid-receptor agonist used primarily as an antidiarrheal medication. It acts on the µ-opioid receptors in the intestinal wall to decrease gut motility, prolonging transit time and allowing increased absorption of fluids and electrolytes. Loperamide HCL is widely used in pharmaceutical formulations to treat acute and chronic diarrhea, including travelers’ diarrhea and diarrhea associated with inflammatory bowel disease. It is a white to off-white crystalline powder, highly soluble in water and commonly supplied in pharmaceutical grade for oral dosage forms.
