Founded in 1922, the Asahi Kasei Group is a diversified manufacturer centered on chemistry. Throughout more than nine decades of growth, we have continued to proactively diversify and adapt our operating portfolio to changes in the economy, changes in society, and changes in the environment. We are now a major global enterprise with operations in the four business sectors of Chemicals & Fibers, Housing & Construction Materials, Electronics, and Health Care.
Ceolus PH grades are the most commonly used grades for oral solid dosage forms. They show excellent performance when used in granulation and direct compression of tablets.
Standard grade. Most widely used for wet granulation tableting.
Larger particle size. Improved flow while maintaining compactibility and distintegration properties similar to PH-101. Used mostly for direct compression tableting.
Larger particle size than PH-102. Increased flow.
Higher bulk density than PH-101. Improved flow and disintegration.
Larger particle size than PH-301 with similar compactibility and disintegration properties to PH-301. Increased flow.
CEOLUSTM KG grades
The key to the compactibility of the Ceolus KG grades lies in their needle-like particle shape. Needle-like particles, once compressed, have less elastic recovery and moreparticle-to-particle entanglements to provide greater tablet hardness.
In particular, KG-1000, offers practically required tablet hardness and friability at concentrations of 10% or less.
CEOLUSTM UF grades
The porous structures and more spherical morphology of Ceolus UF grades contribute to their effective plastic deformation and better flow. They are highly compactible and flowable.
Application of direct compression
Formulation: Ascorbic acid (milled)/MCC/spray-dried lactose/Kiccolate ND-2HS/Mg-St=75/20/3/2/1.5 (weight part)
Tableting: Rotary press (12 punches, 54 rpm with gravity feeder)
Tablet: 180mg, ?8mm, 12R
Croscarmellose Sodium, USP, Ph.Eur, JP
Kiccolate is water insoluble disintegrant obtained by cross-linking of carmellose sodium. Asahi Kasei Chemicals distributes 2 grades of Kiccolate, ND-2HS and ND-200 as sole distributor of Nichirin Chemical Industries, Ltd.
ND-2HS is suitable for low water solubility drug and ND-200 is suitable for high water solubility drug
