(57) [Summary] [Structure] Shellac and a compound capable of keeping the viscosity at 80 ° C when kneaded at a ratio of 0.2 part by weight to 1 part by weight of shellac in the range of 1,000 to 50,000 cP. A base for an allyl isothiocyanate (AIT) preparation characterized by containing. Also, AIT composition containing AIT, shellac, and the compound. Furthermore, a method for producing an AIT preparation using these, and an AI in the AIT preparation Method of preventing variation in T content. Effect According to the present invention, AI of any AIT content It can be used for the production of T-formulation, and AI in AIT-formulation It is possible to provide a base and an AIT composition for an AIT formulation, in which T content is constant and does not cause variations, and thermal curing of shellac does not occur. Further, it is possible to provide a method for producing such an AIT preparation and a method for preventing variation in the AIT content in the AIT preparation. |
