Problems solved by technology

[0003] However, there is a problem that the increase of the abrasive increases the irritation of the oral mucosa and the abrasion of the dentin (dentine), and the increase of the condensed phosphate causes an increase of the irritation of the oral mucosa due to its astringency, and it is impossible to reduce the use feeling without reducing the use feeling. Gives high stain removal power
[0004] In Patent Document 1 (PCT Publication No. 2012 / 124533), although the ratio of the amount of oil, oil / condensed phosphoric acid or its salt in the two-layer separation type liquid oral composition is set within a specific range, thus obtaining Tobacco tar (tobacco tar), stain removal effect is improved, and the astringent feeling is reduced, but there is still room for improvement in the removal of stains. In addition, since it is a composition with a large amount of oil added, it is difficult to use in terms of stability and use. There are also problems with the sense

Abstract

Provided is an oral composition having improved stain removal ability of water-soluble polycondensed phosphate and excellent stain removal effect on teeth, characterized in that it contains: (A) a water-soluble polycondensate represented by the following general formula (1): Phosphate, M n+2 P n o 3n+1 (1) wherein, in the formula, M represents Na or K, and n is an integer of 2 or 3; and (B) one selected from fatty acids and esters having a branched chain structure with 8 to 22 carbon atoms or 2 or more.

Description

technical field [0001] The present invention relates to a composition for oral cavity having improved stain removal ability obtained by water-soluble condensed polyphosphate and excellent stain removal effect on teeth. Background technique [0002] Conventionally, in oral compositions, when removing stains that are a kind of colored stains on teeth, the physical action obtained by increasing the amount of abrasives and / or the chemical action of condensed phosphates such as sodium polyphosphate, etc. Gives a whitening effect. [0003] However, there is a problem that the increase of the abrasive increases the irritation of the oral mucosa and the abrasion of the dentin (dentine), and the increase of the condensed phosphate causes an increase of the irritation of the oral mucosa due to its astringency, and it is impossible to reduce the use feeling without reducing the use feeling. Gives high stain removal power. [0004] In Patent Document 1 (PCT Publication No. 2012 / 124533...
