The present invention provides a method for preparing a whitening cosmetic composition, the invention comprising the steps of: (a) preparing a first mixture by dispersing 100 to 500 parts by weight of an azelaic acid at temperatures of 60 to 120°C with respect to 100 parts by weight of a glycol, preparing a second mixture by dispersing 100 to 200 parts by weight of a surfactant and 200 to 300 parts by weight of a lipid at temperatures of 60 to 120°C, and preparing a highly concentrated azelaic acid by mixing the first mixture and the second mixture; (b) preparing a third mixture by stirring and mixing the highly concentrated azelaic acid in the above step (a), a thickener, a moisturizer and distilled water; and (c) mixing and stirring a physiologically active material to the third mixture in the step (b). The whitening cosmetic composition of the present invention contains a highly concentrated azelaic acid, thereby exhibiting an excellent whitening effect and providing an excellent feeling of use in comparison with cosmetic compositions using conventional solubilized azelaic acid. |
