[0144] (Method of manufacturing gelling agent) The method for producing the above-mentioned gelling agent is not particularly limited. The gelling agent may be obtained by using the above-mentioned reaction product as is, or by mixing the above-mentioned reaction product with the above-mentioned additive as needed, and the method of mixing them is also not particularly limited.

[0145] (Physical properties and uses of gelling agents) The physical properties of the gelling agent described above are not particularly limited.

[0146] In this disclosure, "gelling agent" means a substance that has the function of increasing the viscosity of an oily component, thereby thickening or gelling it. In this disclosure, "gelling ability" means the function of thickening or gelling a target substance.

[0147] Here, the technical effects of "thickening" and "gelling" on oily components are continuous phenomena, and therefore, it is not always possible to clearly distinguish between the two. Generally, "thickening" refers to an increase in the viscosity of an oily component that is liquid at room temperature, and "gelling" refers to the phenomenon in which, after further thickening, the oily component loses almost all of its fluidity and exhibits a gel-like, semi-solid, or flexible solid state, passing through a viscous fluid state such as syrup, cream, or paste. The gelling agent of this disclosure can be suitably used as both a thickening agent and a gelling agent for oily components by selecting the amount used. For example, if a small amount of the gelling agent of this disclosure is added to an oily component, it functions as a thickening agent, and if a large amount is added, it can gel the oily component.

[0148] The reason why the above gelling agent thickens or gels the oily component is not entirely clear, but the following inferences can be made. The reactants self-associate through the reaction of components (A) and (B) to form a salt structure, or through electrostatic interactions or hydrogen bonding of amide groups. Here, since components (A) and (B) are optically active substances, the reactants have a symmetry-lacking structure, making them prone to forming asymmetrical two-dimensional (fibrous) aggregates through self-association. It is inferred that these fibrous aggregates become entangled within the oily component, causing it to thicken or gel.

[0149] In the above gelling agent, when a carboxylic acid other than component (A) (e.g., a higher fatty acid) is used instead of component (A), the gelling ability for oily components tends to be inferior. The reason for this is unclear, but it is thought to be related to the affinity of the carboxylic acid other than component (A) for oily components, and the carboxylic acid itself. It is presumed that this is because, depending on the degree of optical activity, it does not exhibit sufficient gelling ability for oily components.

[0150] In the above-mentioned gelling agent, when an optically active monoamine or a non-optically active diamine (excluding the above-mentioned racemic mixture) is used instead of component (B), the gelling ability for oily components tends to be inferior. The reason for this is not clear, but it is presumed that the reaction products with such amines do not readily form two-dimensional (fibrous) aggregates during self-association, and therefore do not exhibit sufficient gelling ability for oily components.

[0151] In the above-mentioned gelling agent, when component (B1) is a diamine in which the amino group is bonded to an alicyclic structure (for example, a compound represented by the above general formulas (2) to (5)), the gelling ability for oily components tends to be superior. The reason for this is not clear, but it is presumed that the reaction product with such a diamine is more likely to form a two-dimensional (fibrous) aggregate through self-association due to the alicyclic structure, thereby improving the gelling ability for oily components.

[0152] In the above-mentioned gelling agent, when component (B1) is a diamine (for example, a compound represented by the general formulas (3) to (5) above) in which the amino group is bonded to an alicyclic structure and the stereochemistry of the two amino groups is trans, the gelling ability for oily components tends to be superior. The reason for this is not clear, but it is presumed that the reaction product with such a diamine is more likely to form a two-dimensional (fibrous) aggregate during self-association due to the trans stereochemistry of the two diamino groups, thereby improving the gelling ability for oily components.

Then, 17.6 parts of hexamethylenediamine, which had been previously dissolved in 50 parts of acetone, were added dropwise over 30 minutes. After stirring for another 30 minutes, the precipitated solid was filtered off and dried to obtain the diamine salt.

[0251] Comparative Example 2 In a reaction vessel equipped with a stirrer, condenser, and nitrogen inlet, 100 parts lauric acid and 800 parts acetone were charged and completely dissolved under a nitrogen stream, and then the mixture was dissolved in 85 parts acetone beforehand. 28.5 parts of trans-1,2-cyclohexanediamine (50% by mass of (1S,2S)-trans-1,2-cyclohexanediamine and 50% by mass of (1R,2R)-trans-1,2-cyclohexanediamine) were added dropwise over 30 minutes. The mixture was then stirred for another 30 minutes, the acetone was removed by distillation, and the mixture was vacuum-dried to obtain the diamine salt.

[0252] Comparative Example 3 In a reaction vessel equipped with a stirrer, a condenser, and a nitrogen inlet, 100 parts of rosin hydride obtained in Production Example 2 and 400 parts of acetone were charged and completely dissolved under a nitrogen atmosphere. Then, 15.3 parts of dissolved hexylamine, which had been pre-dissolved in 50 parts of acetone, were added dropwise over 30 minutes. The mixture was then stirred for another 30 minutes. After removing the acetone by distillation and vacuum drying, the monoamine salt was obtained.

[0253] Comparative Example 4 A reaction vessel equipped with a stirring device, a cooling pipe, and a nitrogen introduction pipe was charged with 100 parts of hydrogenated rosin obtained in Production Example 2 and 400 parts of acetone. After completely dissolving under a nitrogen stream, 17.3 parts of 1,2-cyclohexanediamine (50% by mass of trans-1,2-cyclohexanediamine and 50% by mass of cis-1,2-cyclohexanediamine) previously dissolved in 50 parts of acetone was added dropwise over 30 minutes. Thereafter, stirring was continued for another 30 minutes, and the precipitated solid was filtered off and dried to obtain a diamine salt.
