One of the inner peripheral surface and the outer peripheral surface is formed with first and second helical grooves extending in an axial direction in parallel with each other, and a third groove extending in only a circumferential direction continuously from one side ends of the first and second grooves. The glycoprotein matrix can be formed by permitting the growth of glycoprotein producing bacteria in the presence of the active ingredient. The surfactants are zwitterionicamphoteric surfactants such as dihydroxyl alkyl glycinate, alkyl ampho acetate or propionate, alkyl betaine, alkyl amidopropyl betaine and alkylimino mono- or di-propionates derived from certain waxes, fats and oils.
