PURPOSE:To obtain the subject composition having improved dimensional stability, strength, touch, feeling to the tongue and toughness by using a specific polysaccharide (derivative), a metal capable of forming bivalent or trivalent metal ion and water as essential components. CONSTITUTION:The objective tubular formed composition having a ratio (R/r) of 1.2-36 (R is maximum outer diameter and r is minimum inner diameter) can be produced by compounding (A) 0.08-12wt.% of a polysaccharide (derivative) (e.g. galactomannan) bonded with a hexose (derivative) (e.g. D-glucose), (B) 0.3-16wt.% (>=71wt.% based on the total mineral substances) of a metal capable of forming bivalent or trivalent metal ion (e.g. Mg), (C)>=40wt.% of water and (D)<=16 pts. (based on 1pt. of the component A) of a polymeric material originated from natural substance (e.g. cellulose), an inorganic filler (e.g. CaCO3), a colorant, a synthetic preservative, a reinforcing material, etc., and pouring the mixture into a closed mold containing a cylindrical core at the center. |
