Profile: Shanghai Shenmei Pharmaceutical Technology Co., Ltd. is an importer and exporter of pharmaceutical excipients. Our products include lactose anhydrous, high substitution hydroxypropylcellulose, hydroxypropyl methyl cellulose, crospovidone, low substitution hydroxypropylcellulose, microcrystalline cellulose, lactose monohydrate and vinylpyrrolidone. High substitution hydroxypropylcellulose is a white powder. It is odorless and tasteless. It can dissolve in many kinds of liquids such as absolute ethyl carbinol, alcohol, isopropyl, dichloride-methane, as well as in acetone, chloroform and acid solution agent. All solutions are clear and transparent. It is a good thermoplastic material with excellent film forming ability. It possesses good chemical inertia and hardly reacts with other chemicals. hydroxypropyl methyl cellulose is nonionic cellulose ether, available in the form of white grayish-white powder or granule. It dissolves in cold water, glacial acetic acid, ethanol, methanol and propylene glycol. It slightly dissolves in acetone depending on the degree of substitutions. It is insoluble in water, ethylene glycol and toluene. It is used as an adhesive & film-forming reagent in pharmaceutical coating, delayed-release and controlled-release tablets or capsules, thickener & water-binding agent in liquid formulation. Low substitution hydroxypropylcellulose is a white or light gray mobile powder with odorless and tasteless properties. It can be dissolved in some organic solvents or some water-organic components. It is applied as an adhesive agent and crack agent forming agent to improve hardness crackability.
