Product Description
1. Molecular Composition and Structure
HPMC has two components: (1) cellulose (2) hydroxypropyl group (3) methoxy subgrade group. On each annulus fibrosis are three hydroxyls.
2. Chemical Properties
(1) appearance: White or whitish powder.
(2) particle size: 80 pass rate >98.5%
(3) apparent density: 0.25 - 0.79g /CC (usually at 0.5 g/CC); Specific gravity: 1.26-1.31 g / CC.
(4) color changing temperature: 190-200 degrees Celsius.
(5) surface tension: 2% aqueous solution: 42-56 Dyn/cm.
(7) Dissoluble in water and some solvents, such as proper-proportion ethanol/water, alcohol/water, methyl chloroform, etc.
(8) HPMC's gel point goes higher as the methoxy content reduces, and its water solubility and surfactant performance decreases as well.
(9) HPMC can thicken solution and is salt resistant. It is characterized by low dash, stable pH and dimension, excellent film forming, as well as a wide range of tolerance of enzyme, dispersion, and viscosity.
3, Application Brief introduction:
This product is a multi-purpose medicinal materials can be used as thickener, dispersant, emulsifier and film-forming agent. Made in the drug tablet film coating, adhesive, can significantly improve the dissolution rate of drugs can enhance the waterproof tablets. Also as a suspension, ophthalmic preparations, controlled release formulations such as skeletons and floating tablets. HPMC and other synthetic polymers and colloidal drug binding, can prevent water and alcohol drugs from the transparent gel to separate the water and improve water retention, is also being food, cosmetics and other areas used as a thickener, emulsifier and improve Rheological properties, as well as to other daily-use chemical industry, etc. Currently this product has become the main material for plant capsule.
