Description

Aquateric CAS NO 105287-09-0 is a high-performance, enteric coating polymer widely used in the pharmaceutical industry. Its primary value lies in its ability to protect active ingredients from the acidic environment of the stomach, ensuring targeted release in the intestinal tract. This product is essential for formulators and manufacturers developing oral solid dosage forms such as tablets and capsules that require delayed or site-specific drug delivery.

Application

• Enteric Coating for Pharmaceutical Tablets and Capsules: Provides acid resistance for targeted intestinal release.
• Controlled-Release Drug Delivery Systems: Used as a functional polymer matrix to modulate drug release profiles.
• Nutraceutical and Dietary Supplement Coatings: Protects sensitive ingredients like probiotics and enzymes from gastric acid.
• Taste Masking Applications: Forms a barrier to prevent the release of bitter or unpleasant-tasting actives in the mouth.
• Film Coating for Improved Stability: Shields hygroscopic or light-sensitive core formulations from environmental moisture and oxygen.
• Specialty Chemical Intermediate: Serves as a raw material for further chemical synthesis in advanced polymer research.

Quality Control

Our Aquateric is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. It is produced to meet relevant pharmaceutical-grade standards, with specifications tailored for enteric coating applications. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing key parameters such as phthalyl content, acetyl value, viscosity, and free acid levels to guarantee compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture uptake, which can affect performance.
