Borax Decahydrate
Borax Decahydrate, also known as sodium tetraborate decahydrate, is a naturally occurring mineral and an important inorganic compound. It appears as colorless or white crystalline granules or powder with a salty, alkaline taste. This compound is widely used in detergents, cosmetics, glass manufacturing, agriculture, and various industrial applications due to its excellent buffering, emulsifying, and antiseptic properties. The “decahydrate” indicates that each molecule of borax contains ten water molecules bound in its crystal structure, contributing to its crystalline appearance and physical properties.
Calcium Propionate
Calcium Propionate is the calcium salt of propionic acid, appearing as a white, crystalline powder or granules with a slightly salty taste and low odor. It is highly soluble in water and used primarily as a food preservative and mold inhibitor. Calcium Propionate inhibits the growth of mold, bacteria, and fungi, making it especially valuable in baked goods, dairy products, and animal feed to extend shelf life and prevent spoilage. It also finds application in pharmaceuticals and cosmetics as a preservative and antimicrobial agent.
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.
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.
Cetirizine Hydrochloride
Cetirizine Hydrochloride is a widely used second-generation antihistamine effective for treating allergic conditions such as allergic rhinitis, chronic urticaria, and other allergy symptoms. It is the hydrochloride salt form of cetirizine, existing as a white to off-white crystalline powder with a slightly bitter taste. Cetirizine HCl acts by selectively blocking peripheral H1 histamine receptors, thereby reducing allergic symptoms without significant sedation or central nervous system depression. It is commonly formulated into tablets, syrups, and capsules as an active pharmaceutical ingredient.
