Abstract

PURPOSE:To obtain the titled composition having increased safety and sustaining the generation of Cl2 and/or ClO2 for a long term by mixing a thixotropic composition contg. polysaccharide with a Cl2 and/or ClO2 generating agent. CONSTITUTION:To a thixotropic composition contg. polysaccharide is added 0.05-0.5wt% amphoteric surfactant such as alkylbetaine, and a Cl2 and/or ClO2 generating agent is further added so that the concn. of available chlorine in the resulting composition becomes 0.5-10wt%, preferably about 1-7wt%. The resulting composition generates stably gaseous Cl2 and/or ClO2, it can generate a very small amount of gaseous Cl2 and/or ClO2 over a long term, and the superior stability is not affected by a sudden change in the temp. of the environment. The polysaccharide can be selected from various kinds of polysaccharides including homo- and heteropolysaccharides.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a chlorine and/or chlorine dioxide generating composition characterized in that a chlorine and/or chlorine dioxide generating agent is mixed into a chicken tropic composition containing a polysaccharide. It is about things.

Chlorine and chlorine dioxide are known to have strong oxidizing properties, and are used as blue bleaching agents, algaecides, disinfectants, deodorizing agents, bleaching agents, antifungal agents, preservatives, etc. However,
Since such chlorine and chlorine dioxide are unstable and difficult to handle, it is difficult to use them alone, and efforts are being made to form compositions with increased stability. Conventionally, such compositions with increased stability include, for example, an aqueous solution of chlorine dioxide stabilized with peroxide of sodium carbonate (USP 3123521);
A stabilized chlorine dioxide aqueous solution or an aqueous solution of an alkali metal or alkaline earth metal chlorite adsorbed on a basic adsorbent (Japanese Patent Publication No. 1983-32079), a chlorine dioxide aqueous solution gelatinized with gelatin Mo-no et al. are known. However, the stability of conventional compositions has not yet been sufficient.

An object of the present invention is to provide a composition that has increased stability and excellent persistence in generating chlorine and chlorine dioxide, unlike conventional compositions.

In order to generate chlorine and/or chlorine dioxide, the present invention does not use chlorine dioxide itself, but uses a chlorine and/or chlorine dioxide generating agent that can gradually generate chlorine dioxide and chlorine. The present invention provides a composition in which polysaccharide is added and mixed into a polysaccharide-containing composition.

As the chlorine and/or chlorine dioxide generating agent, salts of chlorine-containing acids such as hypochlorous acid and chlorous acid, such as alkali metal salts and alkaline earth metal salts, are used. On the other hand, thixotropic compositions containing polysaccharides are disclosed in Japanese Patent Application No. 1973-
These are known as Nos. 63494 to 63499, and are obtained by dispersing polysancalide in a suitable dispersion medium.

In this case, a wide range of polysaccharides can be used, including homopolysaccharides and heterobolyzanocalides, such as galactomanano,
Polysaccharide F derived from natural products such as plant exudates such as glucuronoglucomannan, polysaccharides obtained by microbial fermentation such as products of Leuconostoc bacteria, and products of Xanthomonas bacteria, etc. Can be mentioned. These homo or hetero polysaccharides can be used alone or in combination. There are various types of dispersion medium for polysaccharide, but an aqueous solution consisting of water, a sugar alcohol, and an anionic or nonionic surfactant with an HL 8 value of 5 or more and a penetrating power of within 40 seconds is preferably used. In addition to glycerin, sugar alcohols include sorbitol, mannitol, glucose, fructose, sucrose, and lahinol.

The composition of the present invention is a thixotropic composition containing a polysaccharide mixed with chlorine and/or a chlorine dioxide generator, and the amount of the chlorine and/or chlorine dioxide generator added is not particularly limited. However, in general,
In the whole composition, the effective chlorine concentration is 0.5 to 1O by weight,
Preferably it is about 1 to 7 weight coefficients.

It is preferable to add an amphoteric surfactant to the composition of the present invention, examples of which include alkyl betainos, alkylnoethylene/triaminoacetic acids, etc., and the amount used is as follows: Usually, it is in the range of 0.05 to 0.5 weight factor. This amphoteric surfactant not only uniformly disperses chlorine and/or chlorine dioxide generating agent in the composition, but also has the effect of enhancing anti-fungal, disinfecting, and sterilizing effects, and also has the effect of increasing chlorine gas or chlorine dioxide generating agent from the composition. It has the effect of constantly generating chlorine gas.

Since the composition of the present invention is a mixture of a chlorine and/or chlorine dioxide generating agent with a chicken tropic composition containing polysaccharide, the composition of the present invention is not found in conventional chlorine and/or chlorine dioxide generating compositions. It has various advantages. That is, in the case of the composition of the present invention, chlorine and/or chlorine dioxide gas can be generated stably (constantly), and a trace amount of gas can be generated over a long period of time, and further,
The composition of the present invention has excellent stability even when sudden changes in environmental temperature and humidity occur. Moreover, its physical properties do not change significantly. Furthermore, the composition of the present invention has the following advantages compared to those gelled with agar or gelatin. In other words, products gelled with agar or gelatin tend to deteriorate in composition during long-term storage due to the composition that generates chlorine and/or chlorine dioxide, but this composition does not deteriorate easily and the amount of gas generated is extremely low. become constant.

The composition of the present invention utilizes the action of chlorine and/or chlorine dioxide generated, and can be used for purposes such as deodorization, sterilization, anti-mold, algaecide, etc., as well as for preserving the freshness of fresh foods. It is commonly used as an environmental purification agent. Furthermore, since the composition of the present invention itself has chicken tropism, it is easy to handle, and by fluidizing it, it can be easily filled into containers and bags. Furthermore, the composition of the present invention can be made into a gel or solid by selecting the type and amount of the polysaccharide or hydrophilic colloid IS contained, or can be made into a powder by dehydration. Can be applied in any shape.

Next, examples of compositions of the present invention will be shown.
