"Examples 1 to 10, Comparative Examples 1 to 10"
(1) Evaluation of solubility and coating suitability According to the formulation shown in Table 2, (A) component, (B) component, (C) component or comparative component, (D) component or comparative component, (E ) and (F) were weighed into a 200 mL stainless steel cup so that the total amount was 100.0 g, and then immersed in a hot water bath heated to 80°C or higher, and then mixed with a 30 mm turbine blade attached to a stirrer. was inserted into a stainless steel cup. While maintaining the internal temperature of the stainless steel cup at 80 to 85° C., the mixture was stirred at a rotational speed of 200 rpm for 15 minutes to prepare an anti-caking agent composition.
Immediately after the stirring was completed, approximately 30 mL of the anti-caking agent composition was collected and filled into a polyspray device equipped with a multi-bottle PH-30 equipped with a mini trigger. The remaining anticaking composition was transferred to a 100 mL glass beaker.
The appearance of the anti-caking agent composition transferred to a 100 mL glass beaker was visually observed to confirm the solubility of the anti-caking agent composition at 80°C.
Separately, the polyspray device was moved to a constant temperature bath set at 80° C. and kept warm. The internal temperature of the poly spray equipment was maintained at 80°C, the poly spray equipment was removed from the thermostatic chamber, and the poly spray equipment was immediately activated to solidify with ammonium nitrate (manufactured by Kanto Kagaku Co., Ltd., reagent grade 1) from a height of 300 mm. When the inhibitor composition was spray applied, the spray condition was visually observed to confirm the suitability of application.
Solubility and suitability for application were evaluated using the following evaluation criteria. The results are shown in Table 3.
<<Evaluation criteria>>
〇 (usable level): It is a homogeneous solution state, the viscosity is low, the spray discharged liquid becomes a mist, and it can be uniformly applied to the ammonium nitrate surface.
× (Unusable level): Insoluble matter is observed or the viscosity is high, so it cannot be uniformly applied to the ammonium nitrate surface by spraying.

(2) Evaluation of anti-caking performance 200 g of ammonium nitrate (manufactured by Kanto Kagaku Co., Ltd., reagent grade 1) was placed in a sieve tray (diameter 60 mm x depth 90 mm), spread evenly, and placed on a balance.
Separately, in the same manner as in (1), a polyspray device was filled with the anti-caking agent composition and kept at a constant temperature of 80°C. The internal temperature of the poly spray device was maintained at 80°C, the poly spray device was removed from the thermostatic oven, and the poly spray device was immediately activated to spray the anti-caking agent composition onto the ammonium nitrate in the sieve pan from a height of 300 mm. .25g spray applied. The applied weight was measured to determine the amount (parts by mass) of the anti-caking agent composition applied relative to 100 parts by mass of ammonium nitrate. The results are shown in Table 3.
Immediately after spraying the anti-caking agent composition, the sieve was capped and the sieve was manually shaken up and down and left and right for 1 minute to transfer the ammonium nitrate to a polycup (diameter 65 mm). This polycup was left standing in a constant temperature and humidity chamber (temperature: 30° C., humidity: 85% RH) for 1 hour without a lid. Thereafter, ten 1 kg cylindrical weights (diameter 60 mm) were stacked and placed on the ammonium nitrate in the polycup. Furthermore, in order to prevent the weight from tipping over, a cylindrical cover made of vinyl chloride (90 mm in diameter) was placed over the cylindrical cover, and the cylindrical cover was fixed in place, and the weight was stored in a constant temperature and humidity room (temperature 30°C, humidity 85% RH) for 4 days. Ammonium nitrate was pressure treated.
After the pressure treatment, the polycup was slowly turned over on a sieve tray to remove the ammonium nitrate, and it was visually observed whether the ammonium nitrate remained in a powder state without solidifying into a cylindrical shape, or whether it had solidified into a cylindrical shape. If it solidifies into a cylindrical shape, use a force gauge (manufactured by Imada Co., Ltd., product name "DST-500N") to measure the strength (consolidation strength) required to crush the solidified ammonium nitrate, and evaluate it according to the following evaluation criteria. The results are shown in Table 3.
Note that anti-caking performance was not evaluated for anti-caking agent compositions with an evaluation result of "x" in (1).
<<Evaluation criteria>>
◎ (Excellent quality): Maintains a powder state without solidifying into a cylindrical shape.
○ (usable level): Solidified into a cylindrical shape, and the solidification strength is 1N or less.
△ (target quality not reached): Solidified into a cylindrical shape, the solidification strength is more than 1N and less than 3N.
× (unusable level): solidified into a cylindrical shape, and the solidification strength exceeds 3N.

In Table 2, "A+B" is the total content of component (A) and component (B) with respect to the total mass of the anti-caking agent composition. "A/B ratio" is a mass ratio represented by component (A)/component (B). "E/F ratio" is a mass ratio represented by (E) component/(F) component.
Note that a blank column in Table 2 indicates that the component is not blended.

As is clear from the results in Table 3, the anti-caking agent compositions obtained in each example had excellent anti-caking performance and good solubility and coating suitability.
On the other hand, when component (D) or (F) was not included (Comparative Examples 2 and 4) and when an alkyl fatty acid salt was used instead of component (D) (Comparative Examples 7 and 8), caking occurred. The solubility and applicability of the inhibitor composition were poor.
Cases in which component (C) or component (E) is not included (Comparative Examples 1 and 3) and cases in which a secondary alkylamine or tertiary alkylamine is used in place of component (C) (Comparative Examples 5 and 6) ) and when unsaturated fatty acids or acetic acid were used instead of component (D) (Comparative Examples 9 and 10), the anti-caking performance was poor.
