COSMETIC COMPOSITION COMPRISING EXTRACT CURCUMA LONGA LINNE LEAF AND MANUFACTURING METHOD THEREOF

摘要

The present invention relates to a cosmetic composition comprising Curcuma longa linne leaf extract and a manufacturing method thereof which comprises: vacuum drying Curcuma longa linne leaves under 500-800 hPa of pressure at 40-60C for 5-10 hours; and pascalizing the dried Curcuma longa linne leaves under 10-80MPa of pressure at 25C for 5-45 minutes. The method according to the present invention: minimizes spoilage of the Curcuma longa linne leaves caused during distribution or by hot air drying by vacuum drying the Curcuma longa linne leaves; maximizes elution of useful components contained in the Curcuma longa linne by degrading growth of microbes by ultra high pressure extracting the dried Curcuma longa linne leaves while not damaging active materials in order to effectively sabotage cell walls; and lowers manufacturing costs and is environmentally useful by manufacturing functional cosmetic materials using agricultural by-products such as Curcuma longa linne leaves, but not roots or stem. In addition, the cosmetic composition containing the Curcuma longa linne leaves extract manufactured by the manufacturing method of the present invention uses natural materials instead of chemicals so that long term use can be safe, toxicity and side effects are not existed, and overcomes storage limitation of the natural materials if ultra high pressure extracts the Curcuma longa linne leaves and suppresses the growth of the microbes existed in the the Curcuma longa linne leaves in order to use as cosmetic materials.
