(Industrial Application Field) The present invention relates to artificial saliva, and more particularly to a thickener that is an important element of artificial saliva. Saliva is essential for normal oral and pharyngeal function and for breathing, chewing, speaking, and digestion. However, in cases of xerostomia caused by congenital atrophy, Sio¨gren's syndrome, ductal obstruction, radiation, or after salivary gland removal, salivary secretion is impaired temporarily or over the long term, resulting in many patients suffering from dry mouth. A disorder develops. For this purpose, artificial saliva is used in clinical settings. (Prior Art) These artificial saliva formulations contain various inorganic substances and a thickener for the purpose of delaying the evaporation time of water as essential ingredients. As a thickener, according to Japanese Patent Publication No. 55-26121, carboxymethylcellulose sodium salt (hereinafter referred to as CMC-Na) or sorbitol is preferable, and according to JP-A-59-7116, hydroxypropylcellulose (hereinafter referred to as HPC) is preferable. ) is preferred. Thickeners are used to constantly keep the oral mucosa in a smooth state because it has a viscosity and specific gravity similar to saliva, and does not dry easily. (Problems to be Solved by the Invention) However, within the scope of the prior art, there has been no thickener suitable for artificial saliva that completely satisfies various requirements. In other words, the fluidity required for artificial saliva thickeners,
Mucosal properties, salt resistance, rot resistance, viscosity stability over time, PH
It had advantages and disadvantages in terms of stability, heat resistance, thickening properties, foaming suppression, water retention, etc., and was not satisfactory. The present invention aims to improve the drawbacks of conventional thickeners and provide a thickener for artificial saliva that is particularly excellent in fluidity, spoilage resistance, viscosity stability over time, and foaming suppression. . (Means for Solving the Problem) As a result of intensive research, the present inventor discovered that an alkali metal salt of carboxymethyl cellulose with a high degree of etherification (hereinafter abbreviated as DS) is a thickening agent that meets the above purpose, We have arrived at the present invention. That is, the present invention has a degree of etherification (DS) of
This artificial saliva is characterized by containing an alkali metal salt of carboxymethyl cellulose with a concentration of 1.50 or more as a thickening component. The alkali metal salts of carboxymethyl cellulose (hereinafter abbreviated as CMC) that have been commercially available so far are
Highly substituted CMC, which has a relatively low DS of about 0.6 to 1.2 and has a DS of 1.5 or more used in the present invention, has not been well known until now, partly because it is difficult to produce. In recent years, Japanese Patent Application Publication No. 58-45201,
An efficient multi-stage manufacturing method was developed, as described in Japanese Patent Application Laid-Open No. 176202/1983.
It has also come to be produced industrially. What is commercially available as CMC is the sodium salt of CMC (hereinafter abbreviated as CMC-Na).
Potassium salts can be used in the present invention as well. Various types of polymerization are produced by changing the type of raw material cellulose and manufacturing conditions, or by low viscosity treatment with hydrogen peroxide, but in the present invention, the polymerization degree is increased to 400 or more. It is used because of its excellent viscous effect. The artificial saliva of the present invention contains a CMC alkali metal salt with a DS of 1.5 or more as a thickening component, but it goes without saying that in addition to the thickening agent, various active ingredients that are usually included in artificial saliva are added. Nor. That is, in addition to inorganic ingredients, oral disinfectants such as sodium guaiazulene sulfonate, acidulants such as citric acid, bittering agents such as quinine hydrochloride, sweetening agents such as sorbitate, sugars, pungent agents such as sodium chloride, benzoin, etc. Preservatives such as acids, other essences,
Disinfectants etc. are added. (Example) Examples of the present invention will be shown below to explain the effects of the invention. The types of thickeners used in the test are listed in Table 1.
