[Method for Producing Composition]


The method for producing the composition, (particularly starting material composition for fragrances and cosmetics) of the present embodiment includes the following steps.

    • 1) [First step] reacting glutamic acid or a salt thereof with a fatty acid chloride in a mixed solvent comprising water and an organic solvent to provide a reaction liquid containing a N-acyl glutamic acid or a salt thereof, allowing the reaction liquid to have a pH of 1 to 6 with an acid, and separating the reaction liquid into an organic layer and an aqueous layer at a temperature of 25 to 80° C.
    • 2) [Second step] concentrating the organic layer to dryness under acidity to convert a portion of the N-acyl glutamic acid or a salt thereof into a N-acyl pyrrolidonecarboxylic acid or a salt thereof (component B).
    • 3) [Third step] reacting the N-acyl glutamic acid or a salt thereof with an acid anhydride to provide a N-acyl glutamic acid anhydride.
    • 4) [Fourth step] reacting the N-acyl glutamic acid anhydride with lysine or a salt thereof to provide an acyl group-containing amino acid derivative or a salt thereof (component A).


[First Step]

The acylation reaction step of the present embodiment is a step of condensation-reacting glutamic acid with a fatty acid chloride in a mixed solvent of water and an organic solvent, for example, t-butanol, acetone, methyl ethyl ketone, or isopropanol under the presence of an alkaline compound, and a crude N-acyl glutamic acid is formed by the acylation reaction.


The molar ratio of the fatty acid chloride to the glutamic acid in the acylation reaction step is preferably 1.05 or less, more preferably 1.0 or less, and further preferably 0.98 or less. As the molar ratio of the fatty acid chloride to the glutamic acid is 1.05 or less, the amount of free fatty acid to be formed tends to be reduced.


As the composition of the mixed solvent in the acylation reaction step, the volume ratio of water/organic solvent is preferably in the range of 90/10 to 20/80 and more preferably in the range of 85/15 to 50/50. With the volume ratio in the range of 90/10 to 20/80, the three components: the glutamic acid, fatty acid chloride, and alkaline compound are likely to be compatibilized, and thus the reaction rate can be enhanced.


Although the concentration of the glutamic acid fed in the acylation reaction step is not particularly limited, the viscosity of the reaction liquid increases over time during the reaction, and thus the concentration thereof fed is preferably adjusted to an extent that stirring and mixing can be performed at the time close to the completion of the reaction.


Although the reaction temperature of the acylation reaction step is not particularly limited, the temperature is preferably in the range of −10 to 70° C., more preferably in the range of −10 to 20° C., and further preferably in the range of −5 to 10° C. from the viewpoint of acceleration of the main reaction and suppression of a side reaction.


Examples of the alkaline compound used in the acylation reaction step include, but are not particularly limited to, inorganic bases such as sodium hydroxide, potassium hydroxide, calcium hydroxide, and barium hydroxide.


The pH in the acylation reaction step is preferably maintained at from 9 to 13.5 and more preferably maintained in the range of 10 to 13 from the viewpoint of acceleration of the main reaction and suppression of a side reaction.


The acylation reaction liquid is allowed to have a pH of 1 to 6, for example, with an acid such as hydrochloric acid or sulfuric acid (preferably a mineral acid), the liquid is separated into two layers: an organic layer and an aqueous layer, and the organic layer is provided. In the acylation reaction liquid, the N-acyl glutamic acid formed is present in the form of an alkali salt. Addition of an acid thereto causes the carboxyl groups in the N-acyl glutamic acid partially or entirely to be free acid, thereby separating the liquid into an organic layer and an aqueous layer (acid precipitation step). In accordance with to the pH at the time of the acid precipitation, the dissociation state of the carboxyl groups varies, and the layer separation state, that is, the mass ratio of the organic layer and the aqueous layer and the removability of inorganic salts slightly vary. Thus, the acid precipitation is performed preferably at a pH of 1 to 3 and more preferably at a pH of 1 to 2.5.


The temperature in the acid precipitation step is preferably from 25 to 80° C. The temperature is more preferably from 40 to 70° C. With a temperature of 25° C. or more, there is a tendency that the time taken to reach the layer separation equilibrium can be reduced and when the equilibrium is reached, the amount of the inorganic salt remaining in the organic layer can be reduced.


[Second Step]

In the second step of the present embodiment of the invention, the organic layer provided in the first step is concentrated to dryness to thereby convert a portion of the N-acyl glutamic acid into a N-acyl pyrrolidonecarboxylic acid (component B). The concentration to dryness is preferably performed with warming under normal pressure or under reduced pressure. The concentration to dryness is performed until the loss on drying reaches preferably 10% by mass or less, more preferably 3% by mass or less, and further preferably 1% by mass or less. As the acyl glutamic acid is made into an anhydride in the next step, in order to reduce the moisture, a smaller loss on drying is more preferable.


The “loss on drying” herein means the proportion of the mass to be reduced by drying. Specifically, the loss on drying is the proportion of the mass reduced when 1 g of a specimen is dried at 105° C. for 3 hours, which proportion is calculated by the following expression.





Loss on drying (%)=[{initial specimen mass (g)−dried specimen mass (g)}/initial specimen mass (g)]×100


In the concentration to dryness, the organic solvent and water are preferably distilled off under normal pressure or under reduced pressure initially at a temperature higher than that around the boiling point of the organic solvent, or a temperature around the azeotropic point of the organic solvent to be used and water. When the mass ratio of the organic solvent to water reaches substantially 3% or less, the coexisting acyl glutamic acid is more likely to be foamed, and thus careful control of reduced pressure is required under heating. Even when the organic solvent is substantially distilled off, the moisture still remains. As an actual operation, pressure reduction can be continued around the boiling point of water. Although the above operation requires foaming control, that is, mild stirring adapted to the foaming situation, in comparison with a freeze drying method, in which standing-still is continued under a set temperature, an appropriate amount of an acyl PCA is by-produced at about 10% by mass or less of the acyl glutamic acid and under a high temperature of 85° C., and this acyl PCA can be made useful for emulsifiability and dispersibility in a formulation system.


In this step, for example, as the operation, a freeze drying treatment is used. Substantially no foaming occurs during the treatment, and the drying treatment is simple because there is nothing to do manually, but no acyl PCA is observed.


As the loss on drying is reduced on the organic matter mainly based on the acyl glutamic acid, the foaming attenuates. When a temperature reached of 85° C. or more is maintained for 20 minutes or more at a degree of pressure reduction reached of 200 kPa, the loss on drying will be 10% by mass or less.


In a case in which a more efficient reduction in the loss on drying is desired, the degree of pressure reduction reached is preferably 50 kPa or less and more preferably 20 kPa or less. The temperature reached depends on the melting point and the degree of pressure reduction of the acyl glutamic acid, but is desirably 70° C. or more, more preferably 95° C. or more, and further preferably 105° C. or more.


Setting the loss on drying to 10% by mass or less enables the component B (acyl PCA) to be by-produced from the acyl glutamic acid.


[Third Step]

The solid mainly based on the acyl glutamic acid, which is provided in the second step, is reacted with a carboxylic anhydride such as acetic anhydride to provide a reaction liquid. Filtering-off from the provided reaction liquid followed by drying enables crude crystals mainly based on the acyl glutamic acid anhydride to be provided.


Here, a preferable dehydrating agent is a carboxylic anhydride like acetic anhydride, and acetic anhydride is preferably used from the economic and environmental viewpoint. After the treatment of making the acyl glutamic acid into an anhydride, excess acetic anhydride and acetic acid are removed by filtering-off. In order to enhance the purity of the acyl glutamic acid anhydride, a solid mainly based on the acyl glutamic acid anhydride can be provided by washing with ether and then petroleum ether followed by drying.


[Fourth Step]

The solid mainly based on the acyl glutamic acid anhydride, provided in the third step, is reacted in accordance with Japanese Patent No. 4070768 at the rate of 1 molar equivalent of lysine per 2 molar equivalents of the acyl glutamic acid anhydride, and thus an aqueous solution mainly based on the acyl group-containing amino acid derivative represented by the general formula (A) as described below can be prepared.

<HPLC Analysis Method>

In Examples and Comparative Examples containing the component B described below, the component A and component B were measured from the peak area obtained by an analysis using HPLC described below.


Detector: UV detector (205 nm)


As a measurement instrument, for example, SPD-10Avp, SPD-10AVvp, SPD-20A, SPD-20AV, or the like of Shimadzu Corporation can be used.


Separation tube: a stainless tube of 6 mm in inner diameter and 150 mm in length was filled with silica gel of 5 m in particle diameter and 12 nm in pore diameter modified with octadecylsilyl groups.


Separation tube temperature: a constant temperature around 60° C.


Mobile phase: methanol/water/phosphoric acid=2000/400/0.31


Flow rate: a constant amount around 0.8 mL per minute


More specifically, the component ratio was calculated from the peak area of each of substances detected such as the component A and component B, obtained by an analysis using HPLC. First, the obtained loss on drying was subtracted from the total component ratio 100%, and the value obtained by the subtraction was allotted in accordance with the peak area ratio obtained by the HPLC analysis. Separately, the component B proportion (%) was calculated by the following expression. This proportion corresponds to “Component B proportion (%)” in the following Tables.





Component B proportion (%)=[peak area of component B/peak area of component A]×100


When UV detection is used as described above, the peak sensitivity of the acyl PCA (component B) is higher than that of other substance, and thus a high measurement sensitivity can be kept also in the component B (%) proportion.


Example 1

100 g of the organic layer provided in Production Example 1, which had a component weight ratio of the solid such as lauroyl glutamic acid/t-butanol/water of 62/24/14 was allowed to warm under normal pressure with gentle stirring until the liquid temperature reached 90° C. Then, the layer was allowed to warm while the pressure was gradually reduced, the degree of pressure reduction was gently raised so as to prevent excess foaming, and at a degree of pressure reduction reached of 20 kPa, the temperature reached of 105° C. was maintained for 20 minutes. Then, the pressure was gradually returned to normal pressure, and the melt in the pot was recovered. The provided solid was placed in the refrigerator overnight and pulverized with a juicing mixer. As a result, a solid of 56.6 g was provided. The loss on drying of this solid was 0.25%, and the results of the HPLC analysis were 94.9% of lauroyl glutamic acid, 3.7% of lauroyl PCA, and 0.44% of lauric acid. No other marked impurities were detected.


54.0 g of the solid was dissolved in 36.4 g of acetic anhydride at 50° C., 18.2 g of acetic anhydride was further added thereto, and the reaction was performed still at 50° C. for 3 hours. Then, the temperature was cooled to room temperature, and the product was filtered off from the reaction liquid to thereby provide crude crystals mainly based on N-lauroyl-L-glutamic anhydride. These crystals were washed with 80 ml of ether followed by 15 ml of petroleum ether and dried to provide 34.0 g of a solid. The loss on drying of this solid was 0.24%, and the results of the HPLC analysis were 95.2% of lauroyl glutamic anhydride, 2.3% of lauroyl PCA, and 2.2% of lauroyl glutamic acid. No lauric acid was detected. No other marked impurities were detected.


Further, 9.1 g (0.05 mol) of L-lysine chloride was mixed with 57 g of water. A reaction was performed by adding this solution to 31.1 g of the solid, which was provided by washing and drying as described above, over 2 hours under stirring while the pH range thereof was adjusted with a 25% sodium hydroxide aqueous solution to 10 to 11 and the reaction temperature was maintained at 5° C. After the stirring was continued for further 30 minutes, t-butanol was added thereto at a concentration in the solution of 20% by mass. Then, 75% sulfuric acid was added dropwise to adjust the pH of the solution to 2, and the temperature of the solution was adjusted to 65° C. After completion of the dropping, stirring was stopped, and the solution was allowed to stand at 65° C. for 20 minutes. Then the solution was separated into an organic layer and an aqueous layer, and the organic layer was removed therefrom. Unreacted lysine was substantially recovered in the aqueous layer. After the provided organic layer was subjected to the same water washing operation repeatedly, the solvent was removed from the provided organic layer, and an aqueous solution having a solid content of 30% by mass and a pH of 7 (25° C.) was prepared by neutralization with sodium hydroxide. The solution was distilled under reduced pressure while water was added thereto, and the distillation under reduced pressure was continued at a degree of pressure reduction of 13 to 22 kPa and a solution temperature of 45 to 60° C. until the concentration of t-butanol in the solution reached 10 ppm by mass or less. Finally provided was a 32% by weight aqueous solution mainly based on a composition containing an acyl compound represented by the formula (A), the pH of which solution was 7 (25° C.). The content of the component A was 96.9%, the content of the acyl PCA as the component B was 0.031%, and the content of lauroyl glutamic acid was 2.98%. No other marked impurities were detected. The proportion of the acyl PCA (%) according to the HPLC analysis method described above was 0.032%.
