Cellulose Acetate Phthalate Powder
Cellulose acetate phthalate, also known as cellacefate and cellulosi acetas phthalas, is a commonly used polymer phthalate in the formulation of pharmaceuticals, such as the enteric coating of tablets or capsules and for controlled release formulations.
Cellulose Acetate Phthalate Powder coatings help in resisting prolonged contact with strong acidic gastric fluid, but dissolve in the mild acidic or neutral intestinal environment. It is tasteless and odorless, or might have a slight odor of acetic acid. Cellulose acetate phthalate is hygroscopic and careful precautions are taken to avoid excessive absorption of moisture. Cellulose acetate phthalate is widely used in oral pharmaceutical products and is generally regarded as a nontoxic material, free of adverse effects. However, it may be irritant to the eyes, mucous membranes, and upper respiratory tract.
Polyvinyl Acetate Phthalate Powder
Polyvinyl acetate phthalate is a commonly used polymer phthalate in the formulation of pharmaceuticals, such as the enteric coating of tablets or capsules. It is a vinyl acetate polymer that is partially hydrolyzed and then esterified with phthalic acid.
Polyvinyl acetate phthalate is a viscosity-modifying agent that is used in pharmaceutical formulations to produce enteric coatings for products and for the core sealing of tablets prior to a sugar-coating process. Polyvinyl acetate phthalate does not exhibit tackiness during coating and produces strong robust films. Polyvinyl acetate phthalate is used in oral pharmaceutical formulations and is generally regarded as an essential nonirritant and nontoxic material when used as an excipient. Polyvinyl acetate phthalate is stored in airtight containers because it is relatively stable to temperature and humidity, and does not age, giving predictable release profiles even after prolonged storage. Primarily to ease the clients in getting the accurate and timely release of drug as per release profile required. Our products are ready to mix in drugs and directly compress instead of going through time consuming procedures. Tried and Tested.
