An oral preparation of the present invention contains a multi-composition system including a calcium ion supplying compound; a fluoride ion supplying compound a polyolphosphate ion supplying compound; and, a monofluorophosphate ion supplying compound, wherein the calcium ion supplying compound and the fluoride ion supplying compound are separated within the oral preparation.

Oral preparation system

The invention provides a composition capable of exerting an excellent whitening effect and imparting gloss to teeth. A method for removing a solid product formed on surfaces of teeth, the method containing applying an oral composition to teeth, wherein the oral composition contains 0.05 to 18% by weight of phytic acid or a salt thereof, and contains no polyvalent cation or contains a polyvalent cation in an amount of less than 0.1 fold mol relative to phytic acid, and wherein the oral composition, as diluted with water to 30% by weight, has a pH of 5.5 to 6.5.

Method for removing solid product formed on surfaces of teeth

An absorbent article comprising a liquid permeable topsheet , a liquid impermeable backsheet , and a liquid retentive absorbent member and containing a porous deodorizing agent, wherein the porous deodorizing agent has such pores that the volume of the pores whose diameter ranges from 20 to 200 &angst; is 0.2 ml/g or more, preferably 0.6 ml/g or more.

Absorbent article

Magnetic recording apparatus having reduced friction sliding parts

The present invention provides a glasslike carbon composite material which has reduced surface friction and excellent wear resistance and durability, because of the addition of specific ultrafine ceramic particles as a reinforcing material to a main component of glasslike carbon. The present invention further provides a method for preparing such a glasslike carbon composite material, as well as a method for preparing a glasslike carbon material.

Glasslike carbon composite material and method of preparing the same

The present invention concerns a glass-like carbon material which may be bonded to other materials, the carbon material having a high thermal expansion coefficient and being highly applicable for use as a slider part for a recording medium.
