[0038] i) One or more hydrophilic solvents were placed in a flask at room temperature, and alpha lipoic acid was added thereto as listed in the table, and then dissolved in the mixture.
[0039] ii) The water-insoluble polymer having self-emulsifying properties is dissolved in a hydrophilic solvent and, if necessary, heated while the water-insoluble polymer having self-emulsifying properties is being dissolved. After the dissolution process was complete, the solution was cooled to room temperature.
[0040] iii) The solution formed in step i) is mixed with the aqueous solution of the water-insoluble polymer having self-emulsifying properties formed in step ii).
[0041] iv) The mixed solution formed in step iii) is mixed with a mixture of water and a hydrophilic solvent while stirring slowly, thus preparing a capsule.
[0042] v) After the capsules are fully prepared, the solvent evaporated at a low pressure of 100 mHg and a temperature of 60° C. is removed from the capsules....

[0061] Example 19: Preparation of Cosmetic Compositions Comprising Alpha Lipoic Acid Capsules
[0062] The cream base was from Amorepacific and was used to prepare the cosmetic composition. A cosmetic composition containing alpha lipoic acid was prepared by mixing 90% of the ointment composition with 10% of the capsule composition prepared in Example 1. Each of the prepared cosmetic compositions was stored at a temperature of 35° C. and room temperature for 2 months, and then its smell was observed using a sensory test. At this time, it was found that the odor of alpha lipoic acid was not emitted.
