Abstract

Provided is a liquid oral composition which has an improved effect of preventing the adhesion of stain onto teeth, is free from a sensation of astringency or irritation, does not render the inside of an oral cavity sticky after being applied to the oral cavity, can leave a good sensation particularly after the washing of the mouth with the liquid oral composition, and has a highly clear preparation appearance. A liquid oral composition characterized by comprising (A) a condensed phosphoric acid salt, (B) a hydroxyalkyl cellulose, (C) an acylsarcosine salt and (D) a nonionic surfactant.

Description

technical field [0001] The present invention relates to a liquid composition for oral cavity, which improves the effect of inhibiting the adhesion of tooth stains, suppresses astringent feeling and irritation, and especially has a good feeling of use after gargling, and has a high-clarity appearance of the preparation. Background technique [0002] Condensed phosphoric acid is known to have stain adhesion inhibitory effects in oral compositions (Patent Document 1: JP-A-2000-281548). However, in liquid oral compositions in particular, further enhancement of the stain adhesion inhibiting effect is required. [0003] In addition, condensed phosphoric acid also has the following problems: if it is formulated in an oral composition, it will produce astringent and irritation, which will bring discomfort in the sense of use (Patent Document 2: Japanese Patent Laid-Open No. 10-167940, Patent Document 3: Japanese Patent Application Laid-Open No. 2009-155286), especially after gargli...
