The humidity-dependent antibacterial powdery composition comprises a volatile oily antibacterial substance contained in a high ratio and a water-soluble film forming agent and the behavior of release of the antibacterial substance is changed depending on humidity. The process for producing the same is characterized in that a water-soluble film forming agent optionally together with a powder vehicle is dissolved and/or dispersed in water, subsequently a volatile oily antibacterial substance optionally together with an emulsifying agent is added to the solution and emulsified, and thereafter the obtained emulsion is spray dried into powder. The humidity-dependent antibacterial food storing article is characterized by carrying the humidity-dependent antibacterial powdery composition. The method of storing food is characterized in that the volatile oily antibacterial substance is released from the humidity-dependent antibacterial food storing article toward food lying in an atmosphere of 70% or higher humidity.

A process for producing a sheet for sustained release of a volatile drug, characterized by dissolving a resin serving as an adhesive in a volatile drug and using the resultant solution as a coating fluid to bond a film permeable to the volatile drug to another film permeable or impermeable to the volatile drug. No organic solvent or peeling film for process is used, accordingly, unlike the so far known process. Consequently, it is not necessary to provide the drying step for removing an organic solvent as well as any thermal energy. As a result, the number of production steps can be reduced considerably. In addition, since the volatile drug is homogeneously diluted in the adhesive, the volatile drug can be incorporated accurately and evenly even in an amount as small as 1 g/m or less. According to the process of the invention, a thinner layer containing a volatile drug can be formed.

Process for producing sheet for sustainedly releasing volatile drug

A controlled release composition comprising a volatile compound such as allyl isothiocyanate and a rosin in a proportion of 0.1 to 100 parts by weight of the compound per 100 parts by weight of the rosin, the controlled release composition further comprising a plasticizer, and the controlled release composition laminated on a substrate or in other forms. The AIT controlled release composition of the present invention can be used for emission of aroma, antimicrobial effect, antibacterial effect, insecticidal action, insectproof effect, fungicidal action, fungiproof action, freshness retention, antiseptic or preservative effect and the like.

Antimicrobial agent containing allyl isothiocyanate and method for

An antimicrobial composition comprising AIT and a polyhydric alcohol which may have aldehyde group or ketone group; an antimicrobial composition comprising a surfactant and said composition; a method for treating microorganisms; and a method for retaining freshness of vegetables, etc., both of which methods comprising treating the target substances such as perishables with the composition of the present invention or an aqueous solution containing said composition.

Composition containing allyl isothiocyanate and its use

An self-adhesive article which is produced by forming an adhesive layer from an adhesive consisting essentially of a polymer of which is soluble in or swellable by an iso-thiocyanate, impregnating the adhesive layer with an iso-thiocyanate to provide a biocidal self-adhesive, and applying the biocidal self-adhesive to at least one surface of a base material. A high concentration of the iso-thiocyanate can be held in the adhesive layer, and the self-adhesive article is put to uses intended for the purpose of providing bactericidal, fungicidal and microbiocidal effects in building and food-related fields and the like.

An allyl isothiocyanate spray prepared by dissolving 0.1 to 10% by weight of an allyl isothiocyanate in liquefied carbon dioxide gas and charging the resulting solution into a pressure vessel under a pressurization so that the liquefied carbon dioxide gas can maintain liquid phase. The spray can practically be employed with safety for bacteriostatic or germicidal treatment or for quality preservation.
