Acetic Acid (Food Grade)
Food-grade acetic acid is a clear, colorless liquid organic compound with a pungent vinegar-like odor. It is a high-purity form of acetic acid specifically produced and processed for safe use in food applications. As the main component of vinegar (after dilution), it serves as a critical flavoring agent, pH adjuster, and preservative in the food industry. Food-grade acetic acid typically has a concentration of 80-100% (glacial acetic acid) or is diluted to lower concentrations (4-20%) for specific applications.
Boric Acid
Boric Acid, chemically known as hydrogen borate or boracic acid, is a weak, monobasic Lewis acid of boron. It appears as a white, crystalline powder or granules that are odorless and slightly soluble in water. Boric Acid is commonly used in antiseptics, insecticides, flame retardants, and as a buffering agent in various industrial and pharmaceutical applications. Due to its mild antiseptic and antifungal properties, it is often used in ophthalmic, dermatologic, and other personal care formulations. It also plays a key role in glass and ceramics manufacturing as well as in agriculture.
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.
