The product is formed with hydroxypropyl cellulose and enteric coated
materials at one time to improve the stability. It overcomes the quality defects
of gelatin enteric capsule coated with a film to delay disintegration. Its friability
and deformability keep nomal under low or high temperature, which greatly
prolongs the shelf life. Its moisture content is low (< 10%), suitable for
hygroscopicity and water sensitive drugs or health products.
