Claim 1:
2. A composition in the form of a slurry comprising:
(A) a copolymer of vinyl alcohol and an alkali metal neutralized product of ethylenically unsaturated carboxylic acid and/or (B) carboxymethyl cellulose or a salt thereof;
water; and
an active substance and/or a filler,, wherein when the viscosity of the composition after being diluted with water (25° C. or less) to a viscosity of 1000±900 mPa·s at room temperature (25° C.) and adjusted to a temperature of 25° C. is defined as Xa2 (Pa·s), and the viscosity of the composition after being placed in an airtight container and allowed to stand at 95° C. for 8 hours is defined as Xb2 (Pa·s), the change rate obtained by the following formula is 0 to 10%:

Change rate (%)=(Xa2−Xb2)/Xb2×100,

wherein the viscosities used to calculate the change rate are values measured using a Brookfield viscometer at 30 rpm and a liquid temperature of 25° C.
