, (2010/11/03)
A dental composition for oral use, containing a phosphorylated saccharide (a), a polyphosphoric acid and/or a salt thereof (b), and a cationic bactericidal agent (c), wherein a ratio of a total amount of the phosphorylated saccharide (a) and the polyphosphoric acid and/or a salt thereof (b) contained to an amount of the cationic bactericidal agent (c) contained, i.e. {(a)+(b)}/(c), is from 0.05 to 20 in a weight ratio. The dental composition for oral use of the present invention can be suitably used for an oral cavity cleaning agent, including dentifrice agents such as a paste dentifrice agent, a powder dentifrice agent, and a liquid dentifrice agent, a mouse-wash agent, a troche, a tablet, a cream, an ointment, a bonding agent, a mouth spray, a coating agent to tooth surface or a dental prosthetic, a hypersensitive inhibitor, a therapeutic agent for periodontal diseases, that is applied to a periodontal pocket, wet tissue for oral cavity care, an oral refreshing agent, chewing gum, or a gargling agent, or the like.

A variety of chemical compounds were examined as to their abilities to inhibit the ice nucleating activity of Erwinia ananas IN-10 cells and their outer membrane fraction.The nucleating activity of the outher membrane fraction was inhibited by many surface-active species among the compounds examined, whereas that of cells was inhibited only by amines and ammonium salts having amphiphilic structures.Ammonium salts with both an n-alkyl group having a carbon number of more than 8 and a benzyl group were particularly effective in inhibiting the nucleating activity of the bacterial cells.The inhibitory ability of one of the amphiphilic ammonium salts was greater at 15 deg C than at 4 deg C.When a tea plant was sprayed with one of the effective ammonium salts prior to being kept at -3 deg C overnight, it was possible to protect the plant from freeze-injury at the minimal concentration of 250 ppm.
