USP Grade, or United States Pharmacopeia Grade, represents chemicals and substances that adhere to the rigorous purity and quality standards set forth by the United States Pharmacopeia (USP), an authoritative organization responsible for establishing benchmarks for pharmaceuticals, dietary supplements, and medical products in the United States. These materials undergo extensive testing to ensure they meet strict criteria for identity, strength, purity, and performance, with impurity levels carefully controlled to avoid any adverse effects in medicinal applications. USP Grade substances are manufactured in compliance with Good Manufacturing Practices (GMP), guaranteeing consistency, traceability, and safety throughout production. They are widely used in the formulation of active pharmaceutical ingredients (APIs), excipients, and other critical components of drugs and healthcare products, ensuring that medications are both effective and safe for human use. By meeting these high standards, USP Grade materials play a vital role in maintaining the integrity and reliability of the pharmaceutical industry.

Cellulose Acetate Phthalate (CAP)

 Cellulose Acetate Phthalate (CAP) is a cellulose derivative obtained by esterification of cellulose with acetic acid and phthalic anhydride. It appears as a white to off-white, free-flowing powder that is insoluble in water but soluble in alkaline solutions and certain organic solvents. CAP is primarily used as an enteric coating agent in pharmaceutical formulations, providing resistance to acidic gastric fluids and enabling targeted release of drugs in the intestines. Due to its film-forming, pH-sensitive solubility, and protective properties, CAP is also applied in food, cosmetics, and specialty industrial uses.

Citric Acid Anhydrous

Original price was: $ 2.25.Current price is: $ 2.14.
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.
